Residential building for energy saving by 65％: a case study of Ningbo

Takes Ningbo as an example, using DeST-h creates a model for typical local residential buildings with energy saving by 50％, and defines it as a base residential building. Analyses the energy consumption share of the envelope and energy saving potential of the base residential building, and studies the approach to energy saving by 65％ for residential building in this area. The results show that further energy saving by 30％, which is based on the 50％, can be reached by improving heat insulation of residential envelopes and energy efficiency ratio of heating and air conditioning equipment, and each of the measures takes about the same proportion.
