Energy Efficiency Rating
A measure of the overall efficiency of a building. The higher the rating, the more energy efficient the building.
Environmental Impact Rating
A measure of a buildings environmental impact in terms of CO2 emissions. The higher the rating the lower the impact on the environment.
Low-e glass
Low-emissivity coatings are normally metal oxide coatings applied to glass, primarily to reduce heat losses.
Low energy demand
Industrial/Agricultural buildings which are not fully conditioned but may have localised conditioning for work stations, etc.. May be conditioned for a few days per year to permit seed germination.
Non-Domestic
Not a dwelling (all other)
