or A trained person who uses SBEM software to produce Energy Performance Certificates (EPCs) for Commercial premises.

Dwelling
Self-contained living accomodation for a single household.  Not sharing kitchen and bathroom.

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)

Part L
Building Regulations for England & Wales Approved Document L2

Stand-alone building
A stand-alone building is free standing i.e. entirely detached.

Total useful floor area
Total enclosed space measured internally.

u-value          
A measure of heat flow through a building material.  The lower the u-value the better the thermal
