Research On The Application Of DEST-h Simulation Of Thermal Environment In The Design Of Residential Building Balcony

In recent years, with the improvement of people’s living standard and increased environmental awareness, the requirement of the residential environment is also rising.On the other hand, with the worsening impacts of climate change and the consumption of global primary energy, counties are beginning to develop energy saving strategy. In the construction area, green building, eco-building are being carried out.Studies of residential indoor physical environment could create good living environment for people; on the other hand, could make theoretical basis for building energy-saving technology. As an important part of residential building, Balcony draw people’s attention gradually. From the initial use of functions,people begin to care about the physical properties of their space heat, reflecting the importance of the balcony in which the residential building. As the over space of indoor and outdoor environment, different forms of the balcony has a different effect on the indoor thermal environment of adjoining room.This subject is based on the influence of balcony on the indoor thermal environment. With appropriate model simplification, different enclosed balcony schemes are being built. DEST-h thermal environment simulation software is being introduced to each scheme. The coldest day hourly temperature, the hottest hourly temperature, the annual indoor temperature distribution, the annual energy consumption and other indicators of the simulation results are being comparative analyzed. Through comparative analysis, the characteristics, advantages and disadvantages of the different balconies program in thermal environmental aspect are being summed up. Some recommendations for balcony designs are being made, which are reference for designers.The simulation process of thermal environment of balcony is introduced. Our research works will serve as a guidance and reference on the balcony design; and is optimization of the traditional design. With widely introduce of the DEST-h simulation technology in the design phase, will enhance the science and rationality of design.Our work is a kind of research of application basis. The principle and method is scientific and feasible, but still need to be verified, revised and consummated in a large number of practical projects.
