SAP assessment and domestic air pressure testing

energy assessment that does not cost the earth!...
with over 20 years experience in the construction industry we offer unbiased advice on insulation and new technologies such as ground source pumps, solar energy and ventilation systems.

With the world of energy efficiency becoming more demanding and complex every day it is vital that you can call on a team that knows the nuts and bolts of the ever changing industry. With all that knowledge we are offering a range of services for new build dwellings and the refurbishment of existing dwellings.

As an energy consultancy specialising in assessing new buildings our technicians are qualified and accredited to issue certification in SAP, PEA and EPC as well as air-tightness testing.

here comes the science bit...
SAP is for assessing the energy performance of dwellings. The indicators of the energy performance are energy consumption per unit floor area, an energy cost rating (the SAP rating), an Environmental Impact rating based on CO2 emissions (the EI rating) and a Dwelling CO2 Emission Rate (DER).

SAP 2005 calculates the proposed dwellings energy performance in terms in CO2 emissions per m2 of total floor area per year for heating, hot water, ventilation and lighting.

"The aim is to provide an indication of the energy efficiency of a home that is in a format that can be easily recoginisable by the public in a similar way to "Miles Per Gallon" used to show the energy performance of a car"

who needs a SAP?...
If you are planning to build a new dwelling you will need to have a SAP calculation carried out. You will need a PEA (Predicted Energy Assessment) that can be submitted to building control to show that the building regulations criteria have been met in regard to energy performance.

Once built, an air pressure test result will need to be given to determine the level of air permeability of the dwelling. Finally, an EPC (Energy Performance Certificate) can then be created.
