Net zero fossil energy for heating detached houses in Harbin

Abstract

Following the recognition of the zero energy building concept, the zero energy mass customised houses have received more attention recently. This paper investigates the application of solar energy to achieve net zero on-site energy for space heating in a cold climate. As a case study, a cluster of 30 typical houses in Harbin, China was considered. Harbin is known for its coldest weather and longest winter among major Chinese cities. This study used TRNbuild software to model the house and consequently TRNSYS to determine the total heating load of the cluster of houses. The study focused on fulfilling the heating demand by using a ground source heat pump (GSHP) system. The total electricity c..
