Abstract Building design is important for saving energy and reducing GHG emissions by applying passive solar heating and cooling design principles and using the right materials and appropriate design tools. This will make the home healthier and more comfortable. The design of energy efficient and sustainable buildings is critical for the future. A key aspect of any design is the realistic and accurate prediction of the performance of the building under a wide range of weather conditions. This paper examines the effect of different climate zones in Australia (which are comparable to the world's major climates) on the thermal performance of a complete building and recommended design techniques to suit each climate zone to enhance the overall thermal performance. To examine the effect of the location (different climates) on the overall thermal performance and how a good design in one location may not be suitable at another location, AccuRate will be used to assess the thermal performance for the exact module in different climates zones to allow a fair comparison to find the appropriate design for the climate where the building is located. Also, in this research, each climate zone design requirements and techniques were addressed for various climate variables (including: solar radiation, rainfall, wind speed and direction and humidity) to design sustainable building which save great amount of energy while sustaining occupants thermal comfort.

Maximising cross ventilation is a low energy method of naturally ventilating and providing heating and cooling to deep plan spaces. Significant reduction in the emission of greenhouse gases can be achieved through minimising the use of mechanical systems in regions with climatic conditions that support the use of natural ventilation. Arup has provided input into the design of a louvered facade for the control of external noise for Brisbane Domestic Airport. A full scale prototype facade was constructed and noise transmission loss measurements were undertaken. The results indicate that significant noise reduction can be achieved to enable compliance with the internal noise limits for airport terminals, whilst using natural ventilation. The findings from this research will directly benefit building designers and innovators in the pursuit of achieving sustainable building design.

Modern constructions, either private houses or public buildings, nowadays must be built meeting all the requirements of the European Union [EU] standards and must be highly energy efficient. Still, there are a lot of old inefficient buildings with high energy costs that require renovation. These buildings can be renovated applying a passive house model that helps to minimize buildings’ heating and cooling energy expenses. Moreover, the decisions made in the stages of early design and preconstruction are essential for the sustainability in a building facility. It is possible to perform various analyses with Building Information Modeling (BIM) in order to have an optimized sustainable building design. BIM system can be used to evaluate and control the costs (e.g. renovation, efficiency) as well as to monitor the conditions during the life-cycle of the building.

Professional Assessment

The most progress in the area of the sustainable building policy and its implementation has been achieved in certain regions by the Building Certification System regulations such as Passivhaus (Germany) and LEED (U.S). These solutions are similar to the more widely discussed and already applied concepts: the Integrated Whole Building Design (IWBD) and Building Information Modeling (BIM). Although it may sound trivial, it is vital to acknowledge and understand that a building is an integral component of the land lot. In the stage of development of a building concept, it usually lacks a versatile and professional assessment of available resources, especially those of renewable energy. It is suggested at the beginning of the IWBD concept to conduct such assessment on the resources available and more specifically focusing on renewable energy. The assessment should also meet the expectations of the building’s owner to use effectively the potential of all possible solutions. Thus a certificate is drawn up, defining all the resources available for the particular lot. The structure of the certificate data is orientated towards the possibility of designing modern renewable energy technologies, according to their performance under changing weather conditions during the year. Such assessment certificates contribute to shaping the concept of the building and allow achieving the highest level of its sustainability. Article in Lithuanian.

Juos atitinka vis plačiau diskutuojamos ir jau taikomos viso pastato integruoto projektavimo (VPIP/IWBD, Integrated Whole Building Design – angl.) ir pastato informacinio modeliavimo (PIM/BIM, Building Information Modeling – angl.) koncepcijos. Nors tai skamba trivialiai, bet pastatas yra neatsiejamas nuo sklypo: t. y. stokoja savalaikio, įvairiapusiško ir profesionalaus sklype disponuojamų išteklių, ypač atsinaujinančios energijos, įvertinimo. Pirmame VPIP etape, kuris baigiasi projekto koncepcijos sukūrimu, siūloma atlikti sklypo disponuojamų išteklių, visų pirma atsinaujinančios energijos, pastato savininko lūkesčius atitinkančių jų naudojimo galimybių įvertinimą. Tam parengiamas sklypo disponuojamų išteklių sertifikatas. Jo duomenų struktūra orientuota į galimybę projektuoti šiuolaikines atsinaujinančios energijos technologijas, atsižvelgiant į jų veikimą per metus besikeičiant klimato sąlygoms. Tokie vertinimai padėtų kuriant pastato koncepciją ir leistų pasiekti aukštesnio lygio darnos. Po kelių metų su taip projektuojamais pastatais galima prieiti prie kitokio pastato koncepcijos, sprendinių, išvaizdos ir vertės supratimo.

This research contributes to making residential buildings more efficient in the city of Azraq, Jordan, which is located in a warm climate zone in the Saharan Mediterranean region (classified as a hot desert climate according to the Köppen climate classification). It involved the optimisation of several envelope parameters with the aim of reducing the usage of energy within a normal structure occupying an area of 186 m2 without the occupants’ involvement in saving energy in the building to solely measure the building envelope’s thermal performance. The DesignBuilder software was used for the sensitivity analysis using 12 design variables, which enabled their significance for both cooling and heating loads. The selected variables were separated into two categories based on their level of significance: a group with higher importance (window to wall %, local type of shading, ground floor building, natural rate of ventilation, rate of infiltration, kind of glazing, and flat roof structure) as well as a group with lower importance (partition construction, site position, construction of outside walls, kind of window blinds, and window shade control timetable); these variables will save a significant amount of heating and cooling energy.

The present paper deals with a wide range of issues related to the environmental quality in learning spaces, such as thermal and visual comfort, as well as energy efficiency. All of these issues fall under the umbrella of the UN Agenda 2030 and Sustainable Development Goals (SDGs). Upon reviewing publications of past studies, interviews were conducted and questionnaires were distributed in public high schools in the province of Alicante, located in the Southeast of Spain. Sixteen high schools were selected for the interviews. Fifteen in the city of Elche, which is the total amount of the high schools in the city. One additional high school that was considered important for this research was included in the study due to the characteristics of the building design, excessively exposed to weather conditions. Significant differences were observed between schools built before 2000 and those built after that date. The latter, surprisingly, not more thermally and visually comfortable or energy efficient. The knowledge gained from our investigation will be of great benefit for architects, designers, engineers, school planners and principals in order to establish stronger connections between infrastructures and SDGs. A chart linking recommendations with specific SDGs is also included in this study.

Air Conditioning Systems

Airports, broadly spread world-wide, present continuously increasing energy demands for heating and cooling purposes. Relocatable facilities within them could be built on recycling shipping containers provided with the right insulation layer, to reduce the outstanding consumption of the heating, ventilation and air conditioning systems (HVAC). This research focuses on studying the effect of added insulation on the thermal performance of a construction in the scope of an airport facility, based on a recycled shipping container. Passive heating and cooling insulation strategies have shown good results in terms of energy savings. A series of simulations were performed along six different Spanish airports locations, selected to represent several climate conditions. Temperature evolution inside the container, and energy demands of the HVAC system were obtained to show that the insulation provided by phase change materials (PCM) is performing better than traditional insulation, or a raw container. Although there are slight behavior differences according to the climate, PCM can increase inside temperature even with no HVAC under certain circumstances.

The Impact

<p>Heating and cooling is responsible for about 50% of the European total energy use. Therefore, renewable sources of heat are needed to reduce GHG emissions (e.g. solar, geothermal, waste-heat). Due to a temporal and spatial mismatch between availability and demand of heat, large scale heat storage facilities are needed. High Temperature Aquifer Thermal Energy Storage (HT-ATES) systems are one of the cheapest and most adequate ways to store large amounts of sensible heat. Regular/Low-T ATES systems are considered a proven technology with currently more than 3 000 systems operable world-wide. However, at higher storage temperatures (e.g. 40-100 °C) temperature dependent water properties (density, viscosity) more strongly affect physical processes, resulting in higher and unpredictable heat losses. While first applications and research on this subject started more than 50 years ago, many uncertainties still remain. In this research we study the (hydrogeological) storage conditions that affect the heat losses of HT-ATES systems. Numerical simulations of a wide range of storage conditions, are done to obtain generic insights in the performance of HT-ATES systems. These insights allow to identify which heat transport processes dominate in contribution to heat losses. Results show that conduction always contributes to heat losses for HT-ATES systems and relate to geometric storage conditions. While buoyancy flow (free convection) may also contribute considerable to heat losses under specific conditions.</p>

To improve the energy efficiency of dwellings, rooftop photovoltaic (PV) technology is proposed in contemporary designs; however, adopting this technology will add a new component to the roof that may affect its thermal balance. This paper studies the effect of roof shading developed by solar PV panels on dwellings’ thermal performance. The analysis in this work is performed by using two types of software packages: “AccuRate Sustainability” for rating the energy efficiency of a residential building design, and “PVSYST” for the solar PV power system design. AccuRate Sustainability is used to calculate the annual heating and cooling load, and PVSYST is used to evaluate the power production from the rooftop PV system. The analysis correlates the electrical energy generated from the PV panels to the change in the heating and cooling load due to roof shading. Different roof orientations, roof inclinations, and roof insulation, as well as PV dwelling floor areas, are considered in this study. The analysis shows that the drop in energy efficiency due to the shaded area of the roof by PV panels is very small compared to the energy generated by these panels. The analysis also shows that, with an increasing number of floors in the dwelling, the effect of shading by PV panels on thermal performance becomes negligible. The results show that insensitivity of the annual heating and cooling load to the thermal resistance of rooftop solar systems is only because the total thermal resistance is dominated by roof insulation.

<p>Design inspired by nature has been known as biomimicry or biomimetic design that is believed to transform human technologies into a sustainable status through translation of biological models, systems, and processes. Considering energy efficiency as one of the aspects of sustainability in the concept of bio-inspired building design, the problem was how to access the solutions best matched to the design problem. Various tools for finding existing knowledge from a different domain are described but as yet there appears to be no tool for allowing building designers to access the efficient ways found in nature of producing energy, using energy, and recycling resources. What the research investigated was to find if it is possible to develop a generalised thermo-bio-architectural (ThBA) framework by use of which architects would be able to improve the energy performance of buildings in a wide range of climates, by following a systematic process that methodically connects design thermal challenges to thermal adaptation principles used in nature.  The ThBA was developed by studying biology to find how thermal regulation strategies used by living organisms can be classified and generalised. The proposed ThBA was confirmed and evaluated before it was used for the rest of the research. The biological part of the ThBA was assessed by biological experts within a focus group session. Having the ThBA confirmed, the research also investigated how the heat transfer principles in buildings can be articulated to be linked to the generalised thermal adaptation strategies in nature. For this, a series of case studies were selected and for each an energy simulation was run to analyse its thermal performance and identify its thermal challenges.  Then, the ThBA was used to introduce innovative solutions for improving the thermal performance of the case studies with big energy use to reveal unexpected techniques or technologies. This, however, necessitated its reconfiguration so as to be useful for architects.  Testing the ThBA for two extreme climates in New Zealand, highlighted the fact that the simple translation of the majority of biological thermal adaptation principles are being used by architects, although for some, the architectural equivalents did not function in exactly in the same way as biological thermoregulation strategies. The differences were seen either in the central thermoregulatory principles or the broader properties within which the key principles fitted. Apart from that, for both architectural and biological thermoregulatory strategies the heat transfer parameter and methods were the same. Given that, in a context where biomimicry is understood as the imitation of complicated thermoregulatory solutions in nature for which innovation is evolutionary achieved, the term biomimetics seems to not have a place in the context of bio-inspired energy efficient design considering the current state of technology. The ThBA, however, suggested a few strategies that might address opportunities for designing a new generation of buildings in the future. This implies that the ThBA is more useful for researchers than architects.</p>
