Survey and analysis of energy consumption in office buildings in Tianjin

Abstract

An energy audit of 24 office buildings was conducted in Tianjin, including basic information of buildings, building energy system and energy bills. The investigation results showed that the average intensity of energy consumption in office buildings in Tianjin accounts for 161.51 kW·h/(m²·a). By breaking the energy consumption down into detailed items, it was found that the heating system consumed the highest amount of energy (46.6%), followed by equipment (35.9%), cooling system (11%) and lighting system (6.69%). The main factors for office building energy consumption were found and some feasible measures to save energy were proposed.

Keywords
