Passive energy-saving buildings realized by the combination of transparent heat-shielding glass and energy storage cement

Transparent heat-shielding (THS) glass based on selective absorbing materials has great application prospects in reducing building energy consumption. However, the heat generated by absorbing near-infrared light will also increase the indoor temperature, meanwhile, a single energy-saving material often causes obvious indoor temperature differences. This paper presents an energy-saving building room based on CsxWO3@TiO2 coated glass (CG) and polyethylene glycol (PEG)/halloysite nanotubes (HNTs) energy storage cement (CP/F). The CsxWO3 (CWO) nanoparticles coating with TiO2 enhanced the stability of THS materials. The PEG/HNTs energy storage material exhibits a desirable phase change temperature of 28.70 °C, and relatively high latent heat of 74.84 J/g. The test room result shows that the combination of CG and CP/F can reduce the room temperature by about 10 °C, which is greater than the sum of CG and CP working alone owing to the synergistic effect of two materials, that is, CP/F can absorb part of the heat from CG. The combination of CG and CP/F made the indoor temperature distribution more uniform, with the maximum temperature difference decreasing from 6.7 °C to 3.1 °C. The annual energy saving of CP/F-CG in Changsha and Hong Kong is 14.7 % and 23.4 % respectively, and the economic payback period is 6.57 and 4.82 years respectively. The experimental results provide a new perspective on the development of energy-saving buildings.

Research on environmental green development technology by sustainable utilisation of green sports buildings

This article starts with the concept of green building, points out the necessity of developing green building, and summarises the design criteria of green building. The green sports building technology system structure is proposed, and the resources, environment, energy saving, follow-up utilisation and other aspects such as sustainable use of green sports buildings are discussed. Through research and analysis, this paper uses green design evaluation to simulate the actual project, and proves the feasibility of this evaluation tool. In short, using the concept of sustainable development in the field of green buildings to establish a green sports building evaluation system is of great significance for promoting the development of energy-saving buildings and the sustainable use of sports buildings and other public buildings.

Research on Energy-Saving Design of Building Exterior Pattern for Cold Regions

According to the regional characteristics and climatic features in a cold region, interpret the relationship between building exterior pattern and energy-saving design by do the research on building size, building skin and construction design method,and explore how to combination of both, explore the possibility of the development of energy-saving building forms in a cold region on this basis, and enrich its architectural form vocabulary.

The Research of Energy-Saving Building’s Cost-Benefit Based on the Stakeholders

The main reason for slow development of energy-saving buildings are differences in the benefit of all stakeholders to appeal. Identifying stakeholders, and on the basis of analysis all parties interests and needs, energy-saving building Life Cycle Cost-Benefit Model was established. Then we can find the equilibrium point among the government, developer and consumer, and factors of impacting the development of energy-saving buildings. Last we provide advice for the rapid development of energy-saving buildings.

Analysis on Energy Conservation Materials’ Influence on Energy Saving Construction Cost

Engery-saving buildings are not always high-cost, the construction needs to consider not only the cost of construction, but also the consumption cost in use. We adopt new energy conservation materials and remarkable management mode to reduce the cost of energy-saving building, and fight to get the most benefit with the least investment, in order to master sovereignty in the fierce competition of energy-saving construction market, and to promote the sustainable development of energy-saving building.

Analysis on Life Cycle Cost and Economic Benefits of Self-Thermal Insulation System of Three Different External Walls in Changsha in China

The mathematical analysis model of LCC of self-thermal insulation system of external wall that is applicable to Changsha region is established by using degree days and present worth factor. And the LCC of three commonly used self-thermal insulation systems in Changsha is analyzed by using this model. Analysis results have proven that self-thermal insulation system of external wall has very significant comprehensive economic benefits compared with the wall that energy-saving measures are not taken, and it has an important practical significance to promote the development of energy-saving building in Changsha, China．
