Educational Buildings

An educational building is a kind of public building with a high density of occupants and high energy consumption. Energy-saving technology utilization is an effective measure to achieve high-performance buildings. However, numerous studies are greatly limited to practical application due to their strong regional pertinence and technical simplicity. This paper aims to further optimize various commonly used technologies on the basis of the current national standards, and to individually establish four recommended technology selection systems corresponding to four major climatic regions for realizing nearly zero energy educational buildings (nZEEBs) in China. An educational building was selected as the case study. An evaluation index of energy-saving contribution rate (ECR) was proposed for measuring the energy efficiency of each technology. Thereafter, high energy efficiency technologies were selected and implemented together in the four basic cases representing different climatic regions. The results showed that the total energy-saving rate in severe cold regions increased by 70.74% compared with current national standards, and about 60% of the total energy-saving rate can be improved in cold regions. However, to realize nZEEBs in hot summer and cold winter regions as well as in hot summer and warm winter regions, photovoltaic (PV) technology needs to be further supplemented.

In consideration of the current situation that college buildings are still heated as normal without occupancy,causing energy waste,the on-duty heating will be adopted in college buildings without occupancy under the premise to ensure the indoor comfort requirements.In the case of one college, the energy saving rate and cost saving rate were evaluated for college buildings that used zone and time control heating systems for buildings of different functions.The results show that the annual heating energy saving rate is 34.5%,and the annual heating cost saving rate is 51.5%. In similar collage buildings, 5.48kg of standard coal and 14.43Yuan per square meter of structure area can be saved per year if using zone and time control heating.

This paper analyzed the effect of same insulation materials on energy-saving potential of three different buildings by using the energy simulation program DOE-2. The results show that the heating energy saving rate of the building decreases when the building shape coefficient increases, while cooling energy saving rate of the building rises and the total energy saving rate of the buildings will reduce.

With the increasing pressure of energy exhaustion and environmental degradation, environmental regulation is considered as a strategy to achieve sustainable development. This paper specifically analyzes the mechanism of multi-dimensional environmental regulations on energy- and environment-biased technological progress, and empirically detects the differentiated impacts using China’s panel data from the period 2000–2016, employing the generalized method of moments (GMM) and a dynamic threshold model. The results reveal that: (1) command-and-control regulation (CCR) promotes energy-saving and pollution abatement technological progress. Market-based regulation (MBR) stimulates energy-saving technological progress, while informal regulation (IR) only accelerates environment conservation technological progress. (2) There are threshold effects on the relationship of environmental regulations and biased technological progress. With economic developments, CCR and MBR have positive effects on energy- and environment-related technological progress, whilst IR fails to promote backstop and pollution abatement technological progress. The clear diversity in the impacts of different environment regulations on biased technological progress provides new insights for the optimal future policy design.

Reasonable determination of indoor ventilation rates are the main content of residential ventilation designs, and can save consumption by air conditioners. Firstly, the energy saving potential of ventilation cooling technology in Guangzhou is analyzed in this paper. The cooling load of a residential building in Guangzhou with different air exchange rates is simulated by the DeST-h after indoor heating quantity of different rooms is set. The energy saving rate is analyzed, the functional relation between energy saving rate of ventilation and air exchange rate is obtained using the linear-regression analysis method. After a comprehensive consideration of various factors, including variation of energy efficiency, room volume, air outlet size, and that the maximum air exchange rates of different rooms are fixed.

The concept of spatial boundaries is presented as the joints of the two states of the space. The evolution of the architectural boundaries under the influence of scientific and technological progress is considered. The problems of forming the architectural boundaries in the network of the science and technological progress are revealed. The examples of new environmental concepts in design practice, which include the ability of energy saving, air cleansing, reducing hazardous waste in manufacturing and construction and increasing the environments visual comfort, are such buildings as the Replay Store, Caixa Forum Museum, Hotel Athenaeum, Ann Demeulmeester boutique.
