Reach On Energy Saving Optimizing And Energy Saving Management For Low Energy Housing In Cold Area Of Inner Mongolia

Energy is the material basis of the economic development of a country, which plays animportant role in the social progress and development. For the development of economy, peopleconsume conventional energy sources without restraint, which contain oil, coal, natural gas andso on, and as a result, the excessive exploitation of energy leads to the non-renewable energysources being dried up. At present, building energy consumption of our country accounts formore than30%in our total energy consumption, so it is necessary to carry out energy savingoptimization for the building. Making full use of solar energy sources in Inner Mongolia, andimplementing the energy saving optimization with energy saving managemen in this area toreduce heating energy consumption, it makes a big significance to realize the sustainabledevelopment of economic benefit and energy utilization.This paper took the building in the cold area of Inner Mongolia as the research object, andcombined the software simulation with the management theory as the research method, andconducted the research on energy saving optimization with energy saving management for thelow energy consumption building. The main research contents and results are summarized asfollows:This paper selected the typical meteorological year data in the cold area of Gillan, and usedthe software DeST to set up a building model, and the initial building heat load was simulated to58315.43kW·h. Based on the theory of enclosure structure design, the west wall and the eastwall of building model was optimized, and the influence of different heat preservation materialon building thermal load was analyzed. The analysis results showed that: the lower heat transfercoefficient of the thermal insulation material, the lower building thermal load. Then the paperused the economic present value method of NPV to calculate the optimum economic thickness,the balanced heating building heat load of enclosure structure after optimization was simulatedto24046.36kW·h. Based on the theory of unbalanced heating, the temperature of each roomwas simulated. It stopped heating when the temperature of natural room is higher than18℃,and the unbalanced heating building thermal load of enclosure structure after optimization was simulated to21458.47kW·h.Comparing the balanced heating building thermal load of enclosure structure afteroptimization with initial building thermal load, the energy saving rate is58.77%; Comparing theunbalanced heating building thermal load of enclosure structure after optimization with initialbuilding thermal load, the energy saving rate is63.20%; Comparing the unbalanced heatingbuilding thermal load with the balanced heating building thermal load, the energy saving rate is10.76%. The results show that: the low energy consumption residential can save energyconsumption by using unbalanced heating, which has a significant energy saving meaning to theautomatic adjustment technology according to the climate change in the future, this technologycan avoid overtemperature in the room. At the same time of optimizing the residential program,a whole process of energy saving management to low energy consumption residential is taken.From the investment decision-making stage, planning and designing stage, construction andcompletion stage, inspection and acceptance stage, daily operation and maintenance stage of theproject, the fine management is carried out, and the effective combination of energy savingtechnology and management is realized.
