# High star rating buildings features
# Minimize artificial air conditioning including heating and cooling
# Use of natural cooling processes such as evaporative cooling, natural ventilation and green vegetation
# Use of natural lighting where possible but with heat filtration
# Maximize thermal insulation where appropriate, including synthetic materials and natural insulating barriers such as double glazing and shading. Green roofing where possible can reduce significant cooling load in buildings.
# The use of phase change thermal storage to transfer cooling and heating load to a uniform level.
# Minimize use of direct electric heating
# Optimize the heating and cooling set points for building envelope and hot water supply.
# Minimize water flow at the ablution, showers and basin taps. Bypass mixture of hot and cold water in warmer weather where possible
# Maximizing “containing” the heating or cooling load example – automatic door closer in conditioned space.
