Zero-energy-consumption zero-carbon building calculation method and calculation system

Abstract

A zero-energy-consumption zero-carbon building calculation method comprises the steps of determining dynamic design parameters and a target cooling and heating load value according to meteorological data of an area where a target building is located, basic design parameters of the target building, a target lighting demand and an internal and external heat source ratio; according to the dynamic design parameters, the target cooling and heating load value, the meteorological data, the basic design parameters, the target lighting requirement, the pre-acquired target water consumption and the pre-acquired functional indexes of the target building, determining an equipment form enabling the energy consumption of each active system to be the lowest; determining a total system energy consumption parameter value of the target building according to the dynamic design parameter, the meteorological data, the basic design parameter and the equipment form of each active system; and determining the equipment form of the renewable energy system of the target building according to the total system energy consumption parameter value and the meteorological data. The calculation method can accurately realize zero energy consumption and zero carbon of the target building. The invention further provides a computing system adopting the method.

Description

technical field [0001] The invention relates to a calculation method, especially a calculation method for zero-energy and zero-carbon buildings, and also relates to a zero-energy and zero-carbon building energy calculation system using the above method. Background technique [0002] Zero-energy zero-carbon buildings refer to buildings with zero carbon emissions, can operate independently of the grid, and can run on solar or wind energy. This kind of building does not consume coal, oil, natural gas and other energy sources, and all the annual energy consumption is provided by the renewable energy generated by the site. In addition to emphasizing the passive energy-saving design of the building envelope, the zero-energy and zero-carbon building shifts the energy demand of buildings to renewable energy such as solar energy, wind energy, shallow geothermal energy, and biomass energy, and finds the best solution for the harmonious coexistence of human beings, buildings, and the e...
