This has led to the increase in research on efficient ways to achieve sustainability in cities and develop tools to quantify the environmental impacts they are causing. Life Cycle Assessment (LCA) is considered the most reliable tool to assess these impacts (Loiseau et al., 2012) and has been used immensely by researchers, most notably in the construction sector, to compare between various types of buildings. Recently, focus has shifted towards LCA of neighborhoods, whether to improve urban sustainability policies or to assist eco-design urban development projects (Lotteau et al., 2015). Unlike LCA of buildings, the Life Cycle Assessment of neighborhoods is more complicated and does not only analyze the activities happening within buildings, but rather analyzes the interaction between the different components of the neighborhood, which are the buildings, open spaces, public networks and the transportation sector (Lotteau et al., 2015). Differences in scope, goals, life cycle inventory, and life cycle impact assessment make the comparison between LCA of neighborhoods very difficult. The aim of this study is to conduct a Life Cycle Analysis of a new sustainable neighborhood, under renovation in Dijon, France called Fontaine d’Ouche, which is one of two energy-positive pilot projects adopted by the European Program “Response”. Innovative techniques and solutions are implemented in this neighborhood and the LCA study will attempt to quantify the effect of these solutions on the environment. A simulation tool, called Pleiades, complemented by the environmental database “EcoInvent” will be used for the analysis. Comparison of results will be provided, limitations and uncertainties will be addressed, and recommendations for improvement will be presented.

Schau1*, Tim Mavrič1, Eva Prelovšek Niemelä1, Željko Vene2, Sebastjan Molnar2, Barbara Kobale2 1 InnoRenew CoE, Livade 6A, SI-6310 Isola-Izola, Slovenia 2 Marles, Limbuška cesta 2, Sl-2341 Limbuš, Slovenia * Corresponding author There is an urgent need to reduce greenhouse gas emissions by at least 55% by the year 2030 and to reach climate neutrality by 2050. The building sector is one of the largest emitters of CO2 to the atmosphere. Including energy use in buildings, the sector contributes 31% of the global CO2 emissions (Cabessa et al, 2022). However, the cost of climate friendlier buildings needs to be affordable for the purchaser, while taking into account the emitted CO2 during the use phase. This calls for a carbon footprint evaluation along with an LCC. In this contribution, we investigated an existing prefabricated wooden single-family house and compared it to two different hypothetical scenarios of design with different materials. This building serves as a model for the Slovene construction company Marles, for further development of prefabricated home models. In the first scenario we dealt with the optimisation of the existing building in terms of carbon footprint. We changed the insulation materials from less environmentally friendly to bio-based and reduced the concrete parts in the structure (foundation plate). This change increased the cost of construction. In the second scenario we evaluated the change of construction materials from the existing wooden structure into brick with concrete reinforcement elements and slabs. In this scenario we presented a less environmentally friendly solution but managed a lower cost of investment for the purchaser. The results show that, even with increased energy performance for construction materials, the energy consumption in the use phase dominates the carbon footprint. Nevertheless, there is time to stress the importance of reducing the carbon footprint of construction materials, since energy-reduction policies in the use phase of the buildings are well known and have been put into practice. Detailed analysis of the impact of different construction materials on carbon footprint and LCC, gives better insight into how future construction should be developed.

This contribution aims to catalyze a kick start for cooperation and exchange. Due to further CO2 storage and resource savings in each new life cycle, previously used construction timber has a high potential for transitioning to a circular bio-recycling economy. The state of the art is based on shredding recovered wood and using it in the wood-based panels industry or as an energy source. This represents a disproportionate downcycling in the cascade use of wood. Treatment with wood preservatives is a general obstacle to material and energetic recycling. The goal of TimberLoop is to preserve the structure of wood from previous use as much as possible, to integrate it into the recycling system without complex preparation measures, and to minimize waste streams. The basics for recycling wood from the building industry for the building industry in building products for static load-bearing applications and small-volume wooden building products are created. The wood preservative-free recycling is an essential goal for this. However, apart from individual niches, neither extraction, logistics, technology, products nor the market are established for a large-volume real cradle to cradle-based circular economy that spans the entire wood industry. TimberLoop closes the central gaps in knowledge and is accompanied by life cycle analyses, design concepts and solutions for the recycling and upcycling of this valuable raw material and, thus, avoids the early release of CO2 stored in the wood. A wide range of key players in the Austrian wood industry are working in a network with pioneers of the circular bioeconomy, on solutions for how to use wood in domestic material fl ows in an innovative and sustainable way while preserving the structure and value.

Integration of photogrammetry with 3D laser scanning to model buildings and their external environment create a possibility to compensate for the individual weakness of both techniques. Though the methodology of integrating 3D laser scanning and photogrammetry is promising and has been widely used for several applications, its application as a basis for computational fl uid dynamics (CFD) simulations has not been explored enough. This is partly because, creation of meshes from cloud point data usable for performing CFD simulations can be complicated. The aim of this study is to demonstrate the application of high-speed 3D laser scanning technologies and photogrammetry for CFD simulation of wind fl ow in micro-urban spaces. The methods within this research can be classified into four main steps. The first step included setting-up and acquiring microclimate data as well as point cloud data of the sub-urban space under study using 3D scanner and a drone for aerial photography capture. The second step involved pre-processing of captured data. In step three, the data collected was imported and used to perform wind fl ow simulations around buildings and within the case study area. The fourth step involved post-processing and analysis of simulation results. The results show that the workfl ow presented in this study is an efficient way of performing CFD simulations of existing structures. The findings in this study also indicate that these two technologies compensate for one another. Findings from this study also suggest that integrating these two technologies help in capturing and creating a more accurate and detailed 3d model of micro-urban spaces.

The main objective of the project is to identify experimentally a number of full-scale tall timber buildings (existing or currently being built) and, based on these, develop representative finite element (FE) models for predicting the vibration response of TTBs exposed to wind-induced dynamic loading. The main outcomes of this project will be included in a Guideline for practicing engineers with recommendations for the design of TTBs subjected to wind loads in the Serviceability Limit State (SLS). In-situ measurements were performed at different construction stages. The first experimental data set refers to ambient vibration measurements with two independent sets of measurement devices. The second experimental data set was obtained by exciting the structure at different positions with APS 400 vibration exciter during construction, and the third one after the building was finished. The experimental results were then compared to FE models which represent the building’s dynamic response in terms of eigenfrequencies and mode shapes and was further updated and validated. The effects of parameters such as connections’ stiffness, foundations, mechanical properties of timber (elastic and shear modulus) and non-loadbearing structures such as screeds, partition walls, and façade were analysed. In this study we critically discuss the infl uence of aforementioned parameters on the building’s lateral stiffness, compare the results with the FE model used for the structural design of this building, and provide insights that are essential in determining the correct building stiffness for both seismic and wind design cases.

Basically, building energy demand simulations are done by complex software systems, where environmental, building, and engineering parameters must be set and then an accurate simulation is computed. It takes a lot of time to configure the system, calculate and process the simulation result. Moreover, this process requires time of architect and IT experts. Using regression models to replace these resource demanding simulations would simplify and accelerate optimization processes. Among available regression models, a neural network-based regression model could be suitable for energy demand estimations. Structural fl exibility of neural networks makes them a good choice and popular these days. In this study, the process and results of hyper parameter selections for a neural network regression model is presented. Effects of input selection, network structure, and initialization are measured to support and validate the selection of hyper parameters of the network and model creation. Simplification of network structure and reducing model complexity, has multiple effects. It reduces learning time and could increase generic regression accuracy by less chance of overfitting. The overall result is a dense neural network-based regression model with maximized network performance and minimized network structure and length of learning process. This model can be integrated into building energy demand optimization processes with ease or can serve as base of experiments enhancing regression models by changing input structure.

As its extension, Energia Design Synthesis (EDS) method concentrates on the generation of all feasible and potentially optimal building combinations based on mathematical rigor. For a certain class of family houses, complex dynamic building simulation database was created with IDA ICE. Previously, energy related issues of the database were deeply investigated. (Vincze, N. et al., 2022) In this paper, output parameters related to comfort are considered as a basis of the building design investigations. Based on the results of the simulations, the most infl uential parameters and their dependencies were identified. Fifteen building design variables were selected, for example structure, wall window ratio, orientation, specific surfaces, edges, and vertices together with a complex descriptor specified by architect experts. Morris’ Elementary Effect method was used for the sensitivity analysis performed. The order, dominance, monotonicity, and linearity of the parameters were carefully investigated together with their joint effects. The results were compared to the results of some previously performed energy related investigations.

Rationalization of resource consumption, time, and spent energy are the goals to be achieved, and solutions are sought in the precise monitoring of the production process, identification and utilization of residues, possibilities of product variability and satisfactory product quality. The paper presents results of the concept verification of digitalization of residues in production, for designing new products in the wood industry. As part of the research project for the development of innovative decorative wall panels at the company Spačva Ltd. the development of aesthetic components for wood products from sliced Slavonian oak (Quercus robur) veneer production waste is carried out. Based on the reviewed literature in the field of BIM (Building Information Modeling) and data transformation, the concept of data format conversion from point cloud to NURBS (Non-Uniform Rational Basis Spline) for use in the BIM approach was set (Barazzetti et al., 2015). This work will present the initial part of the research, the goal of which is to create a digital BIM model of the selected wood residue. Concept verification begins with creating a point cloud by laser scanning the residue followed by converting the point cloud into a mesh of surfaces and finally, creating its three-dimensional representation sufficient for further processing in BIM software (Beale et al., 2019). The results of the research will be used to improve the methodology of scanning and data transformation of selected production residues. This improved methodology of scanning and data transformation will later be applied in further research and procedures for creating informational digital models of new veneer wall covering products for Spačva Ltd.

Due to its slow crystallisation, poor thermal stability, and high cost, it is not suitable for long shelf-life food storage applications. Lignin was introduced to improve the thermal and mechanical properties of PLA. Lignin is a three-dimensional aromatic biopolymer which is obtained as a byproduct from the pulp and paper industry. Our preliminary results (mechanical and thermal properties) have shown that 5 wt% and 10 wt% of Kraft lignin (KL) are better weight composition in PLA matrix (Esakkimuthu et al., 2022). Additionally, to improve the antimicrobial property of the packaging film, copper (Cu) nanoparticles were incorporated into the PLA/KL composite through a casting process. Cu nanoparticles were produced using the sodium borohydride reduction method, and characterised using UV and Particle size analyser. The anti-bacterial performance of the composite film was evaluated against foodborne bacteria such as Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive). The proposed work provides significant advances to boost the utilisation of PLA polymer at low costs for various food packaging applications.

This increase is driven by the aspiration to deliver high-rise buildings with enhanced environmental profiles and human well-being. The desire to use wood in construction is pushing the need for fire treatments capable of meeting a products service life. Currently, the majority of fire retardants are water soluble, meaning that exposed, uncoated surfaces are prone to suffer leaching of the treatment over time, meaning that many treatments are regarded as not suited for such outdoor use. In recent years, work at Luleå University of Technology has focused on the combination of wood modification and fire treatment, with an emphasis on encapsulating fire treatment within the modification system, such that they are permanently held within the wood matrix, yet still capable of imparting their fire-retardant properties. This poster will give an overview of the work carried out, primarily with the reagent guanyl urea phosphate (GUP).

Given their high toxicity and hazard to human health, VOC occurrence in the indoor environment leads to sickness symptoms such as nausea, headaches, and skin irritation known as sick building syndrome (Burge, 2004), which affects the wellness of occupants. Long-term exposure to VOCs is also linked to chronic diseases like asthma and cancer. Therefore, efforts are being made to reduce indoor VOC levels in offices and residential buildings. VOC adsorption is a simple yet efficient technology for trapping pollutants from the air into porous support. Carbonaceous materials are suitable for VOC adsorption due to their high porosity and large surface area. For instance, activated carbon and carbon nanotubes and fibers are widely studied for VOC adsorption (Guo et al., 2016; Lee et al., 2010). Nonetheless, the preparation of engineered carbon materials usually requires time and energy besides the utilisation of chemicals. Biocarbon, prepared from organic feedstock, is a cheap and renewable alternative. However, biocarbon has not been well investigated for the purposes of VOC adsorption as it was claimed that the properties of biocarbon, namely surface area and microporosity, require further development to improve the adsorption capacity. In this study biocarbon was prepared from demineralised Arundo Donax and olive stone by-product at variable temperatures (300 °C, 400 °C, 500 °C, 600 °C, 700 °C, and 800 °C). The prepared biocarbon samples were ball-milled to further increase the surface area and pore volume. The samples were characterised by proximate thermogravimetric, scanning electron microscopy, and physisorption analyses and tested for their capacity to adsorb VOCs at ambient conditions.

Previous studies showed that using wood instead of other materials has the potential of reducing environmental impacts (e.g.: Gustavsson et al., 2021; Eberhardt et al. 2019). However, it is unclear how high the potential for improvements is (considering different impact categories). As the construction sector shares the limited resource wood with other sectors it is important to consider the direct effects of increasing the amount of wood in the sector and indirect effects on other wood-processing sectors, e.g. saw residues leading to side effects in the pulp and paper, or panel industry. Apart from that, it is unknown which measures need to be taken to increase the share of wood in the construction sector. Increasing the use of wood and substituting other materials is a complex issue and there are political, economic, social, and technological factors infl uencing the decision of the choice of material for buildings, e.g. price elasticity or the acceptance of wood. Therefore, a system’s perspective needs to be taken, where not only the substitution impacts are assessed but where also the effects of these infl uencing factors are accounted for. We propose a system dynamics model that describes the substitution of wood in the construction sector. The model quantifies the direct and indirect effects of wood substitution for several impact categories. It includes infl uencing factors of substitution in the construction sector to depict the dynamics of the system and gives the opportunity to estimate the impact of different scenarios. The model will show which factors have a high infl uence on increasing the use of wood in the construction sector and the environmental impacts connected with the substitution. This will indicate where actions need to be taken to improve the sustainability performance of the construction sector.

The densification process improves the mechanical properties of wood that can then be used for advanced engineering (structures and other applications). However, as with all cellulose products aimed at the built environment, the fire performance of the densified wood products needs to be characterised. Therefore, cone calorimeter experiments, following the ISO 5660-1 standard (ISO, 2015), were carried out for a range of densified samples of Black poplar (Populus spp.) and European beech (Fagus sylvatica L.) to assess the fire characteristics of densified wood. Densification was performed by thermo-hydro-mechanical (THM) treatment in an open system at 170 ℃ - 200 ℃. Time to ignition and the heat release rate (HRR) were measured during the testing campaign. Three groups of poplar were tested: (1) unmodified specimens, (2) THM-densified specimens, (3) low-molecular-weight phenol-formaldehyde resin-impregnated and THM-densified specimens, while the test on beech only included unmodified specimens and THM-densified specimens. For poplar, the time to ignition increased by 5 times with resin impregnation (when exposed to 35 kW/ m²), whereas the infl uence on time to ignition from densification alone is less clear. The heat release rate (HRR) of poplar was slightly decreased by densification, but the peak HRR increased somewhat by densification. This falls in line with the fact that the mass loss rate of the poplar decreased by densification. More significant results were obtained for beech, as the densification increased substantially by the HRR and mass loss rate. Interesting observations were also made in the analysis of the combustion products. All in all, poplar with resin impregnation and THM treatment is significantly less ignitable than untreated poplar, and densified beech burns at a lower rate than untreated beech.

Fortunately, due to environmental and economic reasons a positive trend has been observed over recent years, attributable to the reuse of secondary raw materials (Tomaszewska, 2020). The demolition, renovation, and modernization of buildings generate a large amount of such waste, which are a valuable source of material resources that can be recycled and reused in construction, including wooden construction. The posibility of reusing secondary raw materials supports their effective maintenance in a circular economy. The study aims to develop a prototype of multifunctional composites in the form of construction and insulation products, produced from secondary raw materials available on the local market, including demolition wood, textile, and leather waste. Innovative materials are dedicated to the construction facililties in technologies based on prefabrication. Modern building materials should comply with basic requirements, such as: strength, resistance to water, resistance to fire, heat insulation, as well as not have harmful effects on human health. In addition to the development of modern products with improved properties, the project will deepen the knowledge regarding the suitability of secondary raw materials for building materials’ production and contribute to the promotion of circular solutions.

The wood was subjected to diff erent combinations of impregnation and densifi cation processes. A water solution with 1%, 2.5%, and 5% carbon was used for impregnating the wood. The impregnation and thermal-hydro-mechanical densifi cation treatments (THM) were performed on four types of wood: Populus nigra (Black poplar), Picea abies (Spruce), Abies alba (European fi r), and Fagus sylvatica (Beech). The physical and mechanical characteristics were evaluated and compared for all samples in relation to the percentage of carbon. It was shown that the addition of 2.5 and 5% carbon particles positively aff ected the mechanical behaviour of spruce wood. In the case of other woods, biochar had no eff ect or at some percentages it had a negative eff ect. In the densifi ed samples the presence of carbon lowered the set-recovery values.

Many VOCs are associated with Sick-Building-Syndrome (SBS), and up to 10% of the population experience symptoms of SBS (Kishi et al., 2020). However, wood is generally regarded as a suitable material for indoor surfaces, as multiple studies indicate positive psychological effects from exposure to wood. In addition, wood surfaces are beneficial regarding their hygroscopic properties, as wood building materials have the potential to reduce seasonal fl uctuations in temperature and relative humidity (Nore et al., 2017). To assess the suitability of wood as an indoor building material it is important to identify the size and profile of VOC emissions from wood. In this study, emission rates of six VOCs were measured during construction of student housing in Fredrikstad, Norway. The main frame of the building was cross-laminated timber (CLT) and air samples were collected from rooms with either ceiling or ceiling and one wall in visible CLT. The sampling was performed during nine weeks of construction, and the air samples were analyzed using TD-GCMS. All emission rates of the VOCs, namely camphene, α-pinene, β-pinene, β-myrcene, 3-carene and hexanal, were below recommended LCI values, indicating no adverse health impact in the indoor environment.

As social changes occur, so do changes in the professional approach in the field of technology, production, and design. It is very important nowadays to rethink technology and processes in order to reduce production waste and design better products for a more sustainable future (Fell, 2010). Based on such an approach, a research and development project is being implemented with the goal of increasing the use of oak logs in the company Spačva Ltd., Vinkovci, Croatia. The aim of this research is to determine what is the residue from the production of oak veneer (Lutz, 1978) and how that residue can be shaped into the design of a new decorative wall panel product. An example of a possible public application of decorative wall panels, such as school classrooms, was analyzed to define the most common wall dimensions. Ratios of proportions were obtained for the development of the final geometry when designing the wall module. The results show that with an innovative approach, a large amount of raw material waste can be exploited and processed into a new product such as decorative wall covering. Further research is moving in the direction of confirming the positive impact on the natural environment, built environment (well-being) as well as the overall business of the company.

Many businesses look for solutions to tackle the waste problem. While garbage separation at the source could play a decisive role, there are no obligatory regulations that require Thai citizens to perform it. However, despite the lack of encouraging programs offered by governmental organizations and authorities, Chak Daeng Temple is an example of attempts to solve this issue at the local level. Alongside advocating Buddhism, this temple has included information on waste separation in an ordinary manner for the locals.

In the learning process, participants themselves create knowledge from experience and then apply it to their own lives. Scardamalia and Bereiter (Visvizi et.al. 2020) call this the theory of collaborative knowledge construction. The theory explains how a community of learners actively creates knowledge and emphasizes the need to educate individuals on how to function in a society where knowledge and innovation are fundamental principles. They add that innovation in education should be understood as ideas that trigger the design of educational modernization, services, and approaches to achieve learning objectives more effectively (Visvizi et.al. 2020). In this paper we will present a pilot project Loose Cells - Innovation at the Crossroads of Art and Science, which was carried out by representatives of different educational institutions, exploring different innovative approaches in the development of art and science to promote sustainable development in education. After the pilot project, we conducted a case study involving data collection through semi-structured interviews with participating students. Based on the data collected, we found that the interdisciplinary approach contributed to the complexity of sustainable development understanding, while encouraging participants to develop creative and innovative visual solutions. The research, therefore, helped to foster the attitude towards education for sustainable development.

In this context, the possibility to give new life to underexploited bio-based side streams and residues has enormous benefits. High quality olive leaves represent a potentially lucrative feedstock for various biorefinery routes; however, the chemical concentration of the extractives varies considerably between feedstock provenance defining the leaf’s industrial value. There is limited availability of analytical technologies suitable for in-field assessment of the chemical-physical properties of biomass. However, intensive progress in smart, portable, and relatively low-cost sensors suitable for the characterisation of materials is occurring. The real challenge is the development of the spectra post-processing routines, especially chemometric models linking the light absorbance spectrum with specific biomass characteristics. Implementation of an approach directly at the site of collection of the leaves will avoid biorefining of poor-quality biomass and allow the highest concentration of extractives to be processed. The desired solution will identify high-quality leaves that feature high concentrations of oleuropein, apigenin-like polyphenols, luteolin-like polyphenols, total polyphenols, oleanolic acid, total triterpenes, essential oil, lignin, cellulose, and hemicellulose. In concomitance with the OLEAF4VALUE project optimal portable spectrometers will be investigated. The required chemometric models will be built without advanced data mining; however, implementation of deep learning for achieving all our goals is not excluded.

The developments in communication technologies have led to the rise of digital platforms and social media. By sharing messages on social media, a wider audience can be reached and a platform for engagement can be created. However, it is important to know what kind of messages to share, and to understand the differences between the various social media channels. In this study we investigated what kind of messages should be shared on institutional social media channels (Facebook, Twitter and LinkedIn) about topics related to sustainable construction (Engineered wood composites with enhanced impact sound insulation performance to improve human well-being), in order to further engage the audience (e.g. general public) and consequently infl uence a change in behaviour. Weekly posts (from May 2022 until August 2022) were shared and the created engagement was monitored and recorded. We created three types of content that varied weekly: a) text-based information related to the research field of wood composites, sound insulation, building acoustics, human well-being, and modelling of the fl oating fl oor and project research activities, b) displaying images related to the project research activities and research equipment used, with a short text caption of the image, c) photographs of researchers working on the project research activities and using research equipment, with a short text caption of the image. Preliminary results of the study showed which type of messages shared on social media channels created more engagement of the general public, and possible differences in engagement among the three social media channels.

Around the world, several methods for carbon accounting of HWPs exist. Globally used IPCC 2016 method for carbon accounting for national inventory reports takes into account the carbon stored in HWPs. However, it uses simplified assumptions about categories and lifespans , failing to provide an accurate account of the carbon stored in all HWPs. Other more detailed methods such as Life Cycle Assessment (LCA), by default consider the neutrality of biogenic carbon, and do not account for timing of uptake and release of CO2. Furthermore, LCA does not consider delayed emissions of carbon over time. The advantage of LCA is nevertheless its standardisation, availability and accessible data, and the capacity to demonstrate impacts of material substitution. The above mentioned and other methodologies for carbon accounting in HWPs should be advanced in order to include environmental impact throughout the forest-based industry, encompassing its manufacturing emissions, end-of-life treatments of wood, and wood substitution. As the basis for methodology development, the present study shows an overview of existing data on carbon storage for selected European countries in HWPs, obtained with various methods (Dias et al., 2012, Pilli et al., 2015, Aleinikovas et al. 2018, Johnston at al. 2017), including LCA (Hoxha et al., 2020, Wiloso et al., 2016), dynamic system models (Braun et al. 2017), and others. Based on the results of the statistical analysis, inputs from experts as well as findings from literature, best practices, and guidance for method improvement and development will be provided. The improved method should be robust and sufficiently detailed to inform a transition towards greener, carbon neutral forest-based industry. Furthermore, cascade utilisation of wood will be included to emphasise the reuse of HWPs in multiple cycles.

On one hand, climate change poses a growing threat to European forests as evidenced by the increasing frequency and severity of heat waves, extended periods of drought, storms, and other natural disturbances over an increasingly larger scale (Seidl et al., 2017). On the other hand, forests mitigate climate change by storing carbon, regulating extreme weather events, and halting land degradation. In addition, forest-related economic activities play an important role in climate change mitigation and adaptation strategies, as innovation and promotion of new forest-based materials and products to replace fossil-based counterparts can have potentially significant environmental benefits (Hurmekoski et al., 2021). Along these lines, we conducted a study to understand the impact climate change has on enterprises in the forest-based and related sectors, their attitudes and motivations that lead them to act regarding climate change and how that is related to innovation strategies and activities. In this study, we present the results of a survey of 293 Slovenian and Austrian companies in the forest-timber sector, which took place in mid-2021. We found that most companies are at least somewhat concerned about climate change, and few have developed related innovations. Their level of concern and analogous activities can to some extent be explained based on the theory of planned behavior (Ajzen, 2011). Based on the results and keeping in mind the theory of planned behavior, we make recommendations on what measures and communication strategies can be used to encourage companies to innovate and consequently contribute to climate change mitigation.

In our research, we believe that the interiors of kindergartens, which involve natural wooden materials containing natural patterns, natural colors, can provide the child with a sense of well-being, security, harmony, and peace. This article aims to expand current scientific knowledge about the positive infl uence of wood material and its impact on educational processes in the architectural environment of kindergartens. Research and discussion opens the topic of using wood material and seeks its application in the context of preschool educational programs such as Montessori, Waldorf, Reggio Emilia, HigScope, Bank Street, Emergent, Ascend, Parent Co-ops and Religious. The article touches on the topic of biophilic design and restorative environmental design. The authors examine the benefits of using solid wood, the design of which is authentic, with or without a fine surface finish, which does not degrade its visual-haptic-olfactory qualities. The topic discusses the architecture and design of the physical environment of the interiors and exteriors of realized kindergartens and examines the interaction of wooden material and the child.

Nowadays, we face a high prevalence of unhealthy movement behaviours, including a lack of physical activity and sleep, which emerged in our industrialisation and urbanisation periods. To develop evidence-based interventions for population-level behavioural change, underlying factors that affect movement behaviours need to be identified. The aim of this study was to examine existing systematic reviews to identify the characteristics of the built environment that affect physical activity, sedentary behaviour, or sleep. Methods: A literature search was conducted in May 2022. We searched PubMed/MEDLINE, using a search query that included keywords “environment”, “movement behaviours”, and “review”. Only systematic reviews, published in English, reporting a relationship between physical activity, sedentary behaviour, or sleep with characteristics of the built environment were included. Results: After screening titles and abstracts for eligibility, we found 75 systematic reviews that reported associations with physical activity, 19 for sedentary behaviour, and 8 for sleep. The reviews (n = 81) reported associations between movement behaviours and numerous characteristics of macro-level environments, including neighbourhood walkability, mixed land-use, proximity of services, housing density, recreational facilities, green spaces, street connectivity, traffic safety, ambient air pollution, and noise pollution. Some reviews (n = 9) also reported associations between movement behaviours and micro-level environments, including aesthetic stairs, fl exible office design, sit-to-stand desks, presence of screen technology, and prompting (e.g., to use stairs). Conclusions: A substantial body of literature reports on the impact of the outdoor built environment on physical activity, while few reviews focused on indoor built environment. The findings suggest a great opportunity to support an active lifestyle through urban design. Given that people spend a considerable proportion of time indoors, studies should further explore the opportunities to promote healthy movement behaviours through indoor design as well.

Burnard1,2 1 InnoRenew CoE, Livade 6a, 6310 Izola, Slovenia, mateja.erce@innorenew.eu 2 Andrej Marušič Institute, University of Primorska, Muzejski trg 2, 6000 Koper, Slovenia, dean.lipovac@innorenew.eu, mike.burnard@innorenew.eu * Corresponding author Background: Older adults, a fast growing and vulnerable group, face physical and psychosocial challenges, while losing resources to satisfy their own needs despite little change in their needs (ten Bruggencate et al., 2019). Because older adults interact with the built environment constantly, it is a promising way to support them as they face these challenges. However, built environments are more associated with satisfying basic needs while neglecting higher needs (Altomonte et al., 2020). To address these gaps, we assessed scientific literature to identify characteristics of the built environment that may address older adults’ basic, psychological, and spiritual needs. Methods: A systematic literature review was conducted following the PRISMA guidelines in November and December 2021 using Scopus, PubMed, Web of Knowledge, and Google Scholar. The search queries included keywords related to “older adults”, “built environment”, and “needs” or “well-being”. Articles were included if they involved people aged 65 years or more and were written in English. Needs were assessed within Maslow’s hierarchy of needs and the Social production function – Successful ageing model (Lindenberg, 1996; Maslow, 1943). Results: 13,533 articles were identified, 72 met inclusion criteria, and additional 5 articles were identified through other sources. The review revealed that older adults’ basic needs are mainly addressed by lighting, paths, sound, and mobility support, psychological with natural environment, views, seats, and sounds, while spiritual needs are addressed with natural environments. Conclusions: The knowledge gained can be used to help designers, investors, and other practitioners to shape the built environment to improve the well-being of older adults by supporting them in meeting their needs.

It is well known that noise levels can aff ect speech intelligibility, which is critical in lecture rooms where information must be conveyed accurately and easily. In this regard, building regulations include requirements for acceptable background noise levels. However, there are no guidelines for choosing the position of noise sources in the room, which is the subject of this study. Using an artifi cial speaker as the source, the generated sound was recorded in a representative university lecture room. In addition, background noise was added, and its position and level were varied. Measured speech transmission index (STI) and perceived speech intelligibility were analysed at two listening positions. The latter was determined by binaural listening tests (N=80). The results show that while the position of the noise source has no signifi cant infl uence on the STI, it can signifi cantly infl uence the perceived intelligibility. The results are important because they show that background noise is not a suffi cient criterion for the inclusion of noise sources in the built environment and that the position of noise sources can be optimised in the design phase.
