“…Generally, modern options for energy conservation in buildings are focused on innovative architectures, shapes, structures, materials of a building, and of course systems utilizing renewable energy [17]. However, these methods do not take human comfort according to the different contexts of use into consideration.…”

Comfort level in the human body is an index that is always difficult to evaluate in a general and objective manner. Therefore, building owners and managers have been known to adjust environmental physical parameters such as temperature, humidity, and air quality based on people’s subjective sensations to yield satisfactory feelings of comfort. Furthermore, electricity consumption could be reduced by minimizing unnecessary use of heating and cooling equipment based on precise knowledge of comfort levels in interior spaces. To achieve the aforementioned objectives, this study undertook the following four tasks: first, providing visualization and smart suggestion functions to assist building managers and users in analyzing and developing plans based on the demands of space usage and electrical equipment; second, using Internet of Things technology to minimize the difference between real situations and those simulated in building information modeling (BIM); third, accurately evaluating interior environment comfort levels and improving equipment operating efficiency based on quantized comfort levels; and fourth, establishing a persuasive workflow for building energy saving systems. Through developing this system, COZyBIM will help to enhance the satisfactions of comfort level in interior space and operate energy consuming equipment efficiently, to reach the target of energy saving.

“…According to the relevant literature, most countries are reducing building energy consumption from two aspects: enhancing the heat insulation of building envelope and improving the efficiency of heating and cooling system [5][6]. In China, the heat transfer coefficient (HTC) of building envelope is regarded as a key index for building energy conservation.…”

In recent years, resource saving and energy conservation have attracted a growing attention across the globe, calling for technical and economic analysis of energy efficiency of exterior walls in buildings. Targeting an actual building project, this paper introduces the energyefficient design software PKPM and the cost analysis software GBQ to the technical and economic analysis of the energy efficiency of exterior walls respectively made of three masonry materials: sintered porous bricks (SPBs), autoclaved aerated concrete (AAC) blocks and ceramsite aerated concrete (CAC) blocks. The analysis shows that the exterior walls made of the CAC blocks achieved the energy conservation requirements with the simplest structure, easiest construction and lowest cost. The application of the CAC blocks in exterior walls can save resources and reduce building energy consumption, achieve excellent technical, economic and social benefits, and should be promoted in building projects.

“…Significant results might be obtained through the energy conscious design of buildings. It was already shown that by proper thermal insulation of the buildings' envelope and rational integration of renewable energy sources important energy savings can be obtained, see for example [4,5]. However, climate change does not help people in their pursuit of reducing the energy use in buildings.…”

The share of cooling is rising in the energy balance of buildings. The reason is for increasing occupants’ comfort needs, which is accentuated by the fact that the number and the amplitude of heat waves are increasing. The comfortable and healthy indoor environment should to be realized with the minimum amount of energy and fossil fuels. In order to meet this goal, designers should know the effect of different parameters on the buildings’ energy consumption. The energy need for cooling is mainly influenced by the glazed ratio and orientation of the facades, the quality of glazing and shading. In this paper the heat load analysis was done by assuming different types of summer days and surface cooling, depending on the glazing ratio, shading factor and solar factor of glazing. It was proven that, for a certain parameter, the sensitivity of the heat load depends on the orientation and chosen summer day. If the glazing area is doubled, the heat load increases with about 30%. Decreasing the glazed area to 50%, the heat load decreases with about 10%. The heat load decreases with about 3% if the g factor is lowered with 25% or the shading factor is reduced with 60%.
