Building energy efficiency testing determines whether the completion acceptance project meets energy conservation requirements through a series of national standards. GB 50411-2007 "Building Energy Conservation Engineering Construction Quality Acceptance Specification" for indoor temperature, hydraulic balance of outdoor pipe network of heating system, water supply rate of heating system, heat transfer efficiency of outdoor pipe network, air volume of each air outlet, ventilation and The total air volume of the air conditioning system, the water flow rate of the air conditioning unit, the total flow of the hot and cold water of the air conditioning system, the total flow of the cooling water, the average illuminance, and the lighting power density are used for energy saving detection.
Public building energy-saving testing based on JGJ/T 177-2009 "Public Building Energy-Saving Testing Standards" for building indoor average temperature, humidity, non-transparent outer protective structure heat transfer coefficient, cold water (heat pump) unit actual performance coefficient, water system back Water temperature consistency, water system supply and return water temperature difference, pump efficiency, cooling source system energy efficiency coefficient, fan unit air volume power consumption, fresh air volume, constant air volume system balance, heat source (dispatch center, heat station) outdoor temperature, etc. .
Energy-saving testing of residential buildings is based on JGJ132-2009 “Energy-saving Testing Standards for Residential Buildings†for indoor average temperature, heat transfer coefficient of main parts of enclosures, internal surface temperature of thermal bridges of external protection structures, thermal defects of external protection structures, and peripherals Energy-saving detection of insulation structure, outdoor pipe network hydraulic balance, water supply rate, outdoor pipe network heat loss rate, boiler operation efficiency, and power consumption ratio.
