SBEM Calculations - for new buildings (Part L2A) & converted buildings (Part L2B)

SBEM Calculations show compliance with Part L* of the Building Regulations. “SBEM Calcs” are required by Building Control at the design stage of a new dwelling to show how it complies with Part L. Once built, the building requires a new set of SBEM calcs to show that what is built complies with Part L. At this stage we produce the as-built SBEM calculations & provide the EPC (Energy Performance Certificate), where required, based on the as-built spec.

SBEM calculations, like SAP calculations for dwellings, are produced by interpreting & inputting building data (areas, volumes, u-values, heating/cooling systems, renewables, etc) into software to show how the building compares to a ‘notional’ building. The calculation ‘passes’ when the CO₂ emissions (BER) is better than the TER for notional building.


Air Tightness Testing (aka Air Pressure Testing, Air Permeability Testing)

Air Testing shows how airtight a building is. The more airtight a building is the less heat energy can escape. A building’s SAP calculations will normally assume a certain level of air tightness in order to achieve a ‘pass’.

An air test is conducted by temporarily installing a fan into an external doorway of a building and either blowing air into, or sucking air out of the building. The fan is set to a series of different fan speeds to show how much air can enter or escape the building, thus showing how airtight the building is. The result (q50) is measured in m3/hour/m2 surface area.


Environmental Noise Surveys

The noise assessments undertaken vary greatly, from a single existing or proposed air conditioning plant to inner city residential developments and large out of town developments. This can also include the measurement, assessment and evaluation of noise pollution from rail, road, aircraft and more recently wind turbines.

All noise surveys are carried out to meet the latest standards and confirm the requirements set out by the local governing department, be it Environmental Health, Planning or Building Control.

We will provide a full technical report that analyses your proposed development, ensuring you will meet the necessary acoustic requirements. We can also recommend what level of sound insulation your development may require.
