Research On The Residential Buildings Energy Efficiency Design And Examination Method And Developing The Software For Shenzhen

The energy consumption of the residential building is the important constitution of the civilian building's energy consumption. And with the development of the economy, its proportion will increase more and more. At present, the building's energy efficiency especially the residential building's energy efficiency of our country has a long distance with the nation's demand and with the other countries. Therefore, the building's energy efficiency especially the residential building's energy efficiency should be given much more consideration and be researched as an important task.Our country has the frame of primary codes and standards of the building's energy efficiency, but the execution of these codes and standards is very faint. And due to lack of the energy efficiency's evaluating system, the building's energy efficiency evaluation is just a process, as a result we can't be sure if a building has gotten the aim of the energy efficiency. So we should research on the energy efficient building's design and evaluating system to use building design's function of forerunner and to guard the examination gate.In the foreign, softwares are commonly used for energy efficient building's design and examination. They have developed many universal energy simulation softwares and special design softwares applying energy efficiency standards. But these softwares have a universal disadvantage that is complexity. Thus, we need find a simple and reliable building's design and examination method which is applying special energy efficiency standard and develop some softwares based on the method. This paper is based on this need to find the method and taking Shenzhen as a example to develop a residential building's energy efficiency design and examination software.The residential building's energy efficiency design and examination method advanced in this paper is based on the model which is brought forward by Hou Yubo and the method in this paper is made two modifications to her model:1) First is to calculate some typical exterior enclosure's basic energy consumption data. Then based these typical basic energy consumption data, regress some formulas which can calculate any exterior enclosure's basic energy consumption data. The aim is to calculate the building exterior enclosure's basic energy consumption according to these formulas.2) Make the exterior wall and the exterior window as independent and individually calculate their energy consumption.The new model has good continuity in the calculation and the calculation range is more wide. Furthermore, users will easily understand some input parameters.According to the new model, the full-year's energy consumption rules of some typical enclosures of Shenzhen have been studied. Besides, by the DOE-2 program, 28 groups' basic data of the typical roofs, 20352 groups' basic data of the typical exterior walls and 57888 groups' basic data of the typical exterior windows have been simulated. Based on these basic data, 1 group's basic energy consumption calculating formula of the roof, 424 groups' basic energy consumption calculating formulas of the exterior wall and 6432 groups' basic energy consumption calculating formulas of the exterior widow have been regressed. Then the data-base of the residential building's exterior enclosure's basic energy consumption calculating formulas of Shenzhen has been built.Based on the new model and the basic energy consumption calculating formulas, the author developed residential building's energy efficiency design and examination software of Shenzhen －ShenEnergy.By contrast the calculated results of the ShenEnergy program and the DOE-2 program, the author analyzed the difference of the two programs. To reduce or eliminate the difference of the two programs, the author built 4 modificatory formulas by ortho-across experiment and curve matching method. And using the 4 modificatory formulas the author modified the ShenEnergy program. After this modification, the two programs have little difference in the calculating results.
