An Energy Performance Certificate shows the official energy rating of a property and its environmental impact on a scale from A to G. A being the most efficient and E being the least. The certificate can also give recommendations on how to improve energy performance.

A SAP Calculation is The Standard Assessment Procedure (SAP) for energy ratings of dwellings. It is a Calculation of a buildings energy efficiency. A SAP rating is scored on a scale of 1 to 100, were 1 is the worst and 100 would indicate no cost for heating/ hot water.

An SBEM or Simplified Building Energy Model, is a Government Defined process in accordance with Building Regulations Part L2a and Part L2b. It is the calculation of the energy performance of new commercial, industrial and or retail buildings. As from 7th April 2007 all new buildings would require an SBEM Calculation.

BREEAM is the world's foremost environmental assessment method and rating system for buildings, with 250,000 buildings with certified BREEAM assessment ratings and over a million registered for assessment since it was first launched in 1990

There are two types of sound test - airborne and impact. Airborne tests are carried out on walls and floors separating dwellings, impact tests are carried out on floors separating dwellings.

An Air tightness test consists of a computerised fan being fitted to a main entrance or suitable doorway. The fan extracts large amounts of air from the building on domestic builds and blows air into the building on commercial builds.

Dynamic Simulation Modelling (DSM)

Simulation modelling enables us to assess every aspect of thermal performance, from annual energy consumption and carbon emissions down to individual surface temperatures.
