The zero-energy building (ZEB) promotes a new building design that is entirely sustainable and does not depend on an external energy source. This concept has commenced being implemented in developing counties in residential buildings. However, this new innovation is limited to small-sized buildings, and further technological advancement is required to implement the ZEB concept to larger buildings. Objective: This study aims to show the various sustainable construction designs and technologies, focusing on ZERO energy buildings. Furthermore, it illustrates the implications of implementing sustainable practices in developments and solutions to achieve a higher rate of green buildings and sustainable construction practices. Sustainable and green construction is a solution to meet the present generation needs without compromising those of the future by exercising sustainable practices that have minimal impact on the environment and are resource-efficient. (Kubba 2010). Specific Objections: This report concentrates in the following objectives: • • • pg. 3 Why there is a growing importance of Green construction. A summary of the latest materials and design and implement Green Construction. An assessment featuring the advantage and disadvantage of available options and what are the innovations in Green construction. (300536) Major Project in Construction Thesis Report 18717857 Background: In the current environmental situation in the world, shifting to more sustainable and greener construction is necessary. According to the world business council on sustainable development (WBCSD) "The construction and operation of buildings require more energy than any other human activity "(Wilkinson & Mangalagiu 2012a). The conventional construction method primarily concerns about endurance, comfort, and cost-efficiency with minimal consideration to the environmental. (Kubba 2010). Sustainable construction and green building might be an effective way to improve human life quality as it aims to conserve the environment and reduce pollution. Growing Importance of Green Construction (Explicit Knowledge) There is a challenge for the humankind to slow down or stop global warming, resource exhaustion and health complications associated with environmental pollution. The building environmental impact is immense, as it balances 40% of the natural resources extraction, 70% of electricity and up to 65% of waste disposed to landfill. These numbers are rising due to the rapidly growing population, and thebuilding's environmental effect is a prominent issue. (Franzoni 2011) Figure 1 shows global CO2 emission by sector. Building Operations and construction are accountable for 39% of the C02 emission. Green building might be an effective solution to reduce CO2 emission. Figure 1 - Global CO2 Emission by Sector Initial Finding pg. 4 (300536) Major Project in Construction Thesis Report 18717857 Green Building Environmental Effect: Green Construction practices have grown to decrease negative environmental effect by incorporating the environmental factor into the construction practices from the initial design stage to building operation. These practices concentrate on reducing environmental impact to a minimum level (Ojo- Fafore, Aigbavboa & Ramaru 2018) In the last decade, there has been a great effort to decrease the energy consumption for appliances, electricity, and thermal control by introducing the latest innovative materials with lower consumption. It is Green Building Economical Effect: The most denounced matter with green construction is the cost of the construction and materials. Advanced sustainable methods tend to cost more than conventional building practices. Most green construction might increase thestructure's price by 2% compared to the Non-Green buildings; however, it has 10 times more financial advantages over thebuilding's entire life cycle. (Khoshbakht, Gou & Dupre 2017) Energy is a considerable cost of building operation that can be decreased through energy-efficient products and correlated methods which are part of green construction design. Maintenance Management in green building is lower than traditional buildings due to thematerials' efficiency and longevity. High Property market value is one of the essential factors that encourage developers to construct green buildings. Better Rent percentage and the shorter vacancy rate is another factor for a developer to consider green building Marketing opportunities for green building is substantial for their economic, environmental, and social advantages Lower Carbon Tax or other related government fees tends to be discounted for green building in developing countries. (Ciora, Maier & Anghel 2015) pg. 5 (300536) Major Project in Construction Thesis Report 18717857 The table below shows the Green building energy cost difference compared to conventional buildings: Figure 2- Reduced Energy use in Green Buildings as compared with Conventional buildings The graph below shows the total cost per unit of floor area, conventional buildings vs Green-certified in America. Figure 3 -conventional building vs. Green (LEED) certified buildings Green Building Health Benefits: Public health research has shown that enhanced indoor environmental conditions are associated with improved health effects and cognitive function. pg. 6 (300536) Major Project in Construction Thesis Report 18717857 Design of the building can have a direct impact on the health of the occupant. The scientifical research around the green building on cognitive function and heath finds that the following factors in green buildings are the foundation of a healthy building: • • • • Adequate Ventilation Air quality Thermal Comfort Noise and Lighting Overall, occupants report better Indoor environmental quality and fewer health problems in certified green buildings than conventional buildings. (MacNaughton et al. 2017) The photos below show different sections of a green-certified building designed with adequate ventilation, high air quality, appropriate thermal comfort, Efficient and natural lighting and sufficient insulation to manage noise pollution Figure 4- Certified Green Building Design pg. 7 (300536) Major Project in Construction Thesis Report 18717857 Figure 5- Certified Building Design Implications with Green buildings, There are several barriers to implement green design and construction in developing countries. Worldwide, the importance of Green developments as been distinguished. However, everygovernment's degree to sustainable practices effectively differs based on the obstacles implementing green projects. These barriers are more evident in developing countries for various reasons. Two of the main reasons have been illustrated below; Green Projects and technologies; There are various green technologies for green buildings, such as doubled glazed windows or energy-efficient HVAC systems designed for specific environments. These technologies and designs are vastly available in developed countries and mainly suitable for a similar climate of the origin country. For example, an energy-efficient HVAC system design in England might not be appropriate to operate in an African country. pg. 8 (300536) Major Project in Construction Thesis Report 18717857 Sustainable Construction in Developing countries; There are various agendas regarding sustainable developments generated in 1992 Summit in Rio in which Agenda 21 was approved for sustainable developments. These different agendas have indicated that billions of dollars have been and will be spent on sustainable construction. Unfortunately, most developing countries have not been able to implement these practices due to the country financial situation, and they primarily rely on developed countries to implement these sustainable practices in sustainable construction. Therefore, these practices are only implemented to meet the developer goals rather than ensure the methods are appropriate and preserved in the long term. (Nikyema & Blouin 2020) Materials and Design of Green Buildings (Tacit Knowledge) The selection of Green building materials is crucial to achieving the highest standard and rating from the primary stage of the design method when strategic decisions are planned and at the construction phase when available materials are selected. Furthermore, the pre-use phase production of green building materials (extraction, production method, and delivery) is crucial to mitigate the environmental impact. The materials can be quantified through parameters uncovered in the procedures (ISO-14040) and Life cycle Assessment (LCA), energy consumption, CO2 emission, water exhaustion. These parameters are fundamental to ensure the environmental impact of green building materials is mitigated. Selecting the materials at the construction phase is as critical as the initial design as the engineer and architect responsible for material selection might have a lack of evaluation tools to select the materials adequately. (Franzoni 2011) The picture below shows the different materials that can be used in green building; pg. 9 (300536) Major Project in Construction Thesis Report 18717857 Figure 6- Green building Materials selection picture Zero Energy Building (ZEB) The latest advancement in renewable energy products has led to developing ZERO Energy building concept suggesting Zero energy used from external sources and all the energy required to generate from the building from the renewable energy product. (Thiel et al. 2013) The zero-energy building concept is consist of the following critical elements with energy efficiency coming first: • • • • • • Use of solar gains Thermal building-integrated photovoltaics (BIPV-T) Window shading Ground cooling system Natural ventilation Natural lighting An example of nearly zero energy building (XXI Building Lismore) The concept of solar gains in ZEB buildings is a neutral building in energy consumption that provides as much energy to the source grid as it uses from the grid). Based on this concept zero energy might be used as a result of two central ideas, Firstly, minimise the building required energy and secondly, pg. 10 (300536) Major Project in Construction Thesis Report 18717857 produce enough energy from solar panels and other materials to credit for the energy used from the grid. The example to demonstrate this concept is XXI building located in Lismore, Table 1- XXI Building information Picture 1 - XXI Building In XXI Building PV units and windows are covering the central building façade. Thebuilding's glass area interacts precisely with the occupied rooms, gathering solar energy, supplying heat and natural light to these areas. the photo below shows the front elevation of this building: pg. 11 (300536) Major Project in Construction Thesis Report 18717857 Building Integrated Photovoltaic - Thermal (BIPV-T) IN XXI building, besides utilising solar gains through windows, the BIPV_T System incorporating the façade in the south also helps for the quality of indoor temperature during the day in warm season when the heat emitted in the course of transforming solar radiation into energy is efficaciously recuperated. Figure 7- building BIPV-T system.- Natural lighting e natural ventilation The central skylight location as a prominent light distributor is important, as also the vents in the doors that connect from south and north space to hallways and the glass areas spread around the building envelop. These features designed for XXI building contribute to a reduction of energy consumption for lighting. There is natural ventilation from the wind through the openings in the façade and the roof. Windows shading Venetian blinds installed outside the windows to reduce direct solar exposure. It is an effective measure during the summer to reduce solar incidence. pg. 12 (300536) Major Project in Construction Thesis Report 18717857 Ground Cooling System A land cooling structure as the source to provide cooled air into the building utilising the earth as the source to cool down the air. The Cooling System has 32 tubes and installed at 4.5 meters deep in the ground. The air enters the lines 15 meters away from the building and cool down to average ground temperature from 13 to 19 degrees and return to the rooms by natural or forced circulation by using fans. This is an efficient way during hot days when the indoor air temperature is substantially higher. Thetubes' air entered the room and caused the room temperature to drop down by 2 to 3 degrees. Figure 8 - Ground colling system Fig. 4 shows the distribution of the XXIbuilding's electric energy used contrasted with the PVmethod's power. pg. 13 (300536) Major Project in Construction Thesis Report 18717857 Figure 9 - Fig. 4. Solar XXI - Electric energy consumption. SolarXXI building – nearly ZEB XXI building shows a combination of integrated renewable energy systems to reduce building energy consumption significantly. This building offers one of the most advanced efficient solutions and strategies from the concept of reducing energy consumption to a level that is equal to the energy produced by solar panels in the building. Figure 10 shows Fig. 5 shows the building performance and the concept of Zero-energy building. Figure 10-XXI building- path to ZEB Renewable energy system (RES) pg. 14 (300536) Major Project in Construction Thesis Report 18717857 RES proposed model for a building RES System is compromising several energy transitions to generate enough energy for electricity, cooling and heating of a building The wind turbine produces the needed energy for electricity of the building that is linked to the grid to offset the low energy level and transfer the additional energy supplied by RES. The heating system that contains a heat pump water heater(HPWH), a gas boiler and solar collector, is linked with a hot water tank(HW) to deliver fan coils and domestic hot water (DHW). A water heater without a tank is placed as a second measure to control the DHW temperature. (Sobhani, Shahmoradi & Sajadi 2020) Figure 11- Diagram of the RES model. The proposed system above shows the integration of all energies consumed in a building to minimise energy wastage and at the same time, produce energy that contributes to the energy demand of the building. A path towards positive energy buildings (PEB) pg. 15 (300536) Major Project in Construction Thesis Report 18717857 The case study below demonstrates how a practical and integrated design provides enough energy for the building energy consumption demand and produces an energy surplus that could transit back to the urban supply. The table shows the main comparison between Nearly zero energy building to positive energy buildings. (Magrini et al. 2020) Peb is intended to produce excess energy and is a system to efficiently distribute the energy to external sources. Therefore, the concept of PEB is comprised of several buildings linked to each other at a suburb o contribute to the energy demand of buildings through a controlled distribution system. Figure 12- Energy Distribution between PEN buildings An example of PEB building: pg. 16 (300536) Major Project in Construction Thesis Report 18717857 This building has a conventional design and construction built in italy in 2013. This shows that high efficiency does not mean that the building needs to have a modern line. This building has three levels with the usable area of 322m2. The building was constructed with 52cm, of which 35 cm of filled blocks and fibreglass insulation) it been built with a thermal transmittance U=0.19W/)m2k, with triple glazed wooden frames defined by U=1.30W/(m2k) The thermal power plant is located in the basement of the house, which includes: The electrically charged air-water heat pump with the heat output of 13.1KW and operational control operation button which controls for cold temperature airconditioning with combining to the luminous floor and supply of DHW; The mechanical, ventilation that consist includes of an enthalpy exchanger hat operates consistently around the clock and entails a flow of air changing from m3/h and 550 m3/h; A dehumidifier, A 500 L water tank linked to panels of thermal system. This building has a building control system and building management system that controls humidity and indoor temperature to a comfortable level based on the given information. Therefore, the climate control unit has been installed to collect temperature and moisture level from the north of the building. (Magrini et al. 2020) Furthermore, the peculiarities are the existence of a trapped greenhouse facing south and an expansion of the livable areas on the first d floor. In summer, it acts as a helpful build-up of heat, which can be transferred through, which gets air from the greenhouse, employing two 100 m3/h fans, when the temperature surpasses 3 °C the of the inside environment, inserting it in the rooms. The coverage, concerning the parallel plane on the south of the building, with a photovoltaic structure that satisfies the electricity consumption, and a solar thermal system which helps the pg. 17 (300536) Major Project in Construction Thesis Report 18717857 pump to supply Hot Water (DHW). This strategy guarantees nearly total demand for building from renewable sources (94%). Figure 13-Difference between Design energy consumption and real consumption The difference between electricity consumption and the photovoltaic system generated indicates that the building consumes only 34% of the energy to meet consumer's needs. The energy surplus is transferred to the urban supply, with high financial benefit compare to the little costs in winter, in which the solar radiation is not adequate to cover energy utilisation.(Wilkinson & Mangalagiu 2012b, Zhang, J. et al. 2021) Design From the perspective of Zero-Energy Building, the design is the most critical phase to achieving the highest energy efficiency as most choices are selected at this stage. Architectural aspects of Zeb buildings have a significant influence on achieving energy efficiency. The New architecture should pursue to achieve the maximum efficiency in the management of linked resources and the highest generation of renewable energy. ZEB model setting By 2050, the concept of zero energy building will inevitably continue to grow substantially. Various building development approaches provide very diverse future. To study the possible ways and strategy options to achieve the best path to energy efficiency and CO2 reduction three models are described, under these three models, the total volume of extreme- pg. 18 (300536) Major Project in Construction Thesis Report 18717857 low, close to zero and zero energy buildings will rise 50%,75% and 100% by 2050 individually. (Wang et al. 2021, Aelenei & Gonçalves 2014) the table below shows descriptions of these models: ZEB-1 ZEB-2 ZEB-3 2016 2020 2030 2040 2050 Existing buildings ExtremeLow energy buildings Close to ZEB ZEB 100% 95% 85% 70% 50% 0% 5% 10% 15% 25% 0% 0% 5% 10% 15% 0% 0% 0% 5% 10% Existing buildings ExtremeLow energy Close to ZEB ZEB 100% 90% 75% 50% 25% 0% 10% 15% 20% 30% 0% 0% 5% 20% 20% 0% 0% 5% 10% 25% Existing buildings ExtremeLow energy Close to ZEB ZEB 100% 90% 60% 30% 0% 0% 5% 20% 25% 30% 0% 5% 15% 30% 30% 0% 0% 5% 15% 40% Table 2 -Percentage of building types for the study models Figures-7 compare possible energy building consumptions towards the future. In BAU and CAP, energy usage resumes to rise over time and gets to 2456.8 and 1992.6 Mtoe, individually, by 2050. For the three zero building developments, energy consumption first rises and then declines. (Zhang, S. et al. 2020) Three different zero energy building consumption show below pg. 19 (300536) Major Project in Construction Thesis Report 18717857 Figure 14- Building Energy Consumption(2020-2050)Consumption for five scenario Conclusion It is inevitable with the growing concerns with global warming from conventional buildings and construction adverse effects to not adopt green building methods to reduce energy consumption, resource exhaustion, and ultimately decreasing CO2 emission. The Zero-energy building concept (ZEB) is the final goal that many countries strive to achieve, requiring global cooperation to succeed.
