Study on Optimization of Rural Housing Energy-saving Reconstruction Strategy in Severe Cold Area

Abstract

Unreasonable design of the outer envelope structure of rural houses in severe cold areas leads to high heat consumption index, poor indoor comfort and increased heating cost in winter. In order to solve this problem, this paper takes a rural house in Heilongjiang as an example, establishes a three-dimensional model using BIM technology, calculates the heat consumption of existing maintenance structures, and proposes an energy-saving renovation scheme. The energy-saving percentage is obtained by numerical calculation before and after the energy-saving renovation of the rural houses using building energy consumption simulation software DeST, and the investment cost of the energy-saving renovation scheme is given through economic and technical analysis. The energy consumption of the reconstructed building is reduced, the indoor comfort is improved, and the people’s happiness is enhanced.
