Abstract:

 To certain extent, existing buildings are limited by design and technology. Their poor energy efficiencies cannot reach current standards and cause irreversible influences on the environment. Using Ecotect, the efficiency of a small museum in Zengcheng City is simulated and analyzed. The result demonstratesthat after using natural ventilation and heat insulation designs, the architectural environment including lighting is much improved, which may provide a theoretical basis for architectural enhancement in the Lingnan region.
