What is home energy audit?
一个家庭能源审计包括建筑围护结构，包括所有组件, 如墙壁, 天花板, 地板, 门, 视窗, 等各成分具有特定电阻, 这就是所谓的U值. 在能源审计, 每个组件R值被测量或估计的. 这项工作的目的是量化建筑的整体散热性能.
审计工作还可以评估效率, 健康状况, 和机械系统，如加热的编程, 通风, 空调设备, 和恒温器. 能源审计工作还考察了泄漏，如空气泄漏. 漏风率是指通过建筑围护结构的空气渗透率.
对于一个完整的能源审计, 它应该包括报告的书面分析. The report must estimated the seasonal energy consumption for typical climate data. This could show the seasonal energy consumption for a given time period with specified equipment setting equipment. 当然, the accuracy of energy estimates depends on the are actual homeowner’s billing history, included electricity, natural gas, fuel oil, or other energy sources consumed over a one or two-year period.
To be more precise, an interview must be conducted between the energy auditor and the home owners. The correct analysis may include the truth information given by the home owner to the auditor. By using some others climate data provided by local authorities, such as heating degree day and cooling degree day, the local weather data in combination with the thermal energy model of the building, the energy billing history from the local utility company can be calibrated. Those data will be easily simulated to provide the seasonal energy profile by using the home energy software which is much available in the market.
