Calculation method of operational carbon emission for HVAC in Carbonemission calculation standard for civil buildings of Zhejiang Province

This paper presents the calculation boundary of operational carbon emission from civil buildings, and the calculation method of operational carbon emission from cold and heat sources, transmission and distribution systems and air systems in this standard. This standard expands and extends the calculation boundary of carbon emissions from civil buildings, and covers the whole boundary of the whole life cycle. This standard defines the nominal operating conditions of buildings, and unifies the standard building use mode and equipment operation mode in the carbon emission calculation of civil buildings. The detailed algorithms of HVAC systems are supplemented, and the calculation formulas of operating energy consumption and carbon emissions of air conditioning cold and heat sources, transmission and distribution systems, terminal air treatment equipment and ventilation fans are given. It improves the operability of carbon emission calculation of buildings in Zhejiang Province.
