“…A case study in India examined the energy efficiency of every system in an office building located in different climates. It showed the correlation between building envelopes and the energy consumption of HVAC systems that result from a reduction in heat transfer in buildings through high-efficiency material and external shading [29]. Another case study in Spain also evaluated the retrofitting of building envelopes and showed a reduction in residential building energy consumption by 12% [30].…”

“…Many studies have discussed the potential of retrofitting building envelopes in conjunction with local limitations such as climate, local policy, and occupant behaviour by using case studies in their specific locations [27][28][29][30][31]. In a case study from Egypt, a retrofitted educational building demonstrated that a simple retrofitting strategy on a building envelope can reduce the average energy consumption up to 33% even though the building is located in a hot climate [27].…”

The building envelope has a direct impact on the overall energy consumption of a building. Thus, an improvement in the building envelope using energy-efficient material can yield the desired energy performance. This study is based on the materials and compositions used in building envelopes in compliance with the building energy code of Thailand. The building under study is an educational building located in Bangkok, Thailand. Both the energy and the economic aspects of retrofitted building envelopes are discussed in this study. The energy performance was evaluated by calculating the thermal transfer value and whole building energy consumption using the building energy code (BEC) software. The simulation was done under the assumption that the building envelope in the case study building was retrofitted with different materials and compositions. The study determines the feasibility of retrofitting buildings using energy-efficient material by utilizing the discounted payback period and internal rate of return (IRR) as indicators. The results show that retrofitted building envelopes in every case can reduce the whole building energy consumption. In the best envelope configuration, energy consumption can decrease by 65%. In addition, the economic potential is also high, with an IRR value of approximately 15% and a payback period of 23 less than nine years. These finding indicate that a building envelope made with energy-efficient material can achieve good results for both energy performance and economic feasibility.

“…Solar thermal heating systems are utilized in millions of residences worldwide [1] and have made a great contribution to the sustainable development of the earth [2]. Solar water heaters are not only widely used in rural China [3] but also in rural areas in Australia [4], Turkey [5], India [6], and parts of Africa [7]. However, it is more urgent for urban buildings to improve energy efficiency and reduce emissions [8].…”

Solar Water Heating Systems Applied to High-Rise Buildings—Lessons from Experiences in China

High-rise buildings have a significant impact on the surrounding environment. Building-integrated solar water heating (SWH) systems are effective ways to use renewable energy in buildings. Impediments, such as security concerns, aesthetics and functionality, make it difficult to apply SWH systems in high-rise buildings. At present, only China uses SWH systems on a large scale in such buildings. What are China’s experiences and lessons learned in applying SWH systems in high-rises? Are these experiences scalable to other countries? This study used a combination of field investigation, literature review and case study to summarize 36 systems that had been in operation for 1–14 years. System types, collector types, installation methods, types of auxiliary heat sources, economic performance and various basic principles were summarized. The economic performance of SWH systems in high-rise buildings was analyzed and verified by a case study in Shanghai. The results show that the installation of SWH systems in high-rise buildings is feasible and reliable as long as appropriate design, construction, operation, and maintenance measures are employed. China's unique practical experience gives a reference for other countries in their efforts to make high-rise buildings more sustainable.

“…Over the centuries humans have tried to develop ways and means to provide adequate shelter for the surrounding environment to achieve thermal comfort within. He developed a traditional home, which achieved thermal comfort based on natural resources and the primitive strategies of passive solar design [1,2].However, the modern house neglected to take into account climate elements in achieving thermal comfort. Instead, the buildings relied on electrical equipment that uses energy while the world faces a major energy problem.…”
