Abstract: In order to overcome the problems of low energy-saving rate and high net energy consumption existing in the urban residential zero-energy building feasibility model, this paper proposes a new solar source urban residential zero-energy building feasibility model based on Laplace transform method. The Laplacian transform of the energy-saving design parameters of the solar energy source urban residential zero-energy building is used to build a feasibility model of the urban residential zero-energy building. The feasibility parameters of the urban residential zero-energy building are calculated based on the feasibility model, and consumption of building feasibility. The experimental results show that the feasibility model of urban residential zero-energy building construction greatly improves the energy saving rate, the highest energy saving rate can reach 93%, the net energy consumption is reduced, and the minimum energy consumption is only 80 kg/t.

Keywords: Laplacian transformation; solar energy; urban housing; zero-energy-consuming; building; feasibility.
