The Research On Residential Energy-saving Design Based On The Energy Consumption In Changsha Area

Residential building energy efficiency research has been the study of buildingenergy efficiency is an important task. Cold and cold regions of northern residentialbuildings only consider winter insulation, building envelope materials are also just alarge thermal inertia insulation materials, subtropical region is also just considersummer heat, does not require envelope insulation treatment. However, hot summerand cold winter areas should take into account the summer heat and winter insulation,so hot in summer and cold winter area is the study of energy-saving design emphasisand difficulty.Currently, energy-saving residential Changsha winter indoor thermalenvironmental improvement and energy consumption reduction effect is not obvious,affecting the enthusiasm of the owners and developers, and the need to increaseinvestment, improve the cost resulting in a new waste. Therefore, Changsha, Hunanarea proposed for the overall strategy of energy-saving design, is a serious problem.For the hot summer and cold winter zone building energy research, the country hascarried out many aspects of the study, but the overall design of strategic studies lessrelevant systematic treatise is rare. The author through participation issues, and basedon existing research and further studies on energy saving strategies, the use ofsoftware simulation and field pilot testing, developed an optimal design of residentialenergy strategy, making residential buildings more energy efficient.First through statistics and analysis, summarized in Changsha traditional andmodern residential flat and tectonic advantage and analyzed and summarized the typeand characteristics of the local climate, from the architectural space and graphicdesign, envelope design, passive strategies and behavior patterns, etc., summarize atypical residential apartment.Then, while maintaining the thermal environment in certain circumstances, inorder to evaluate the energy consumption indicators, through Designbuild software tobuild a typical apartment, and orderly conduct of software simulation experiment: theproportion of energy through the building envelope simulation to determine factorsaffecting energy envelope The focus of the research object, for these factors tointermittent and continuous two consumption habits were simulated to obtainenvelope and passive strategies related to design strategy. Through field tests before and after the transformation of traditional residentialenergy improvement, to verify the feasibility of the design strategy. Finally summedto target residential energy saving design strategies.
