For Professionals
Thessla Green MVHR Units are listed on the database for the Building Energy Performance Assessment as can be found from clicking the link. AirPackHome 4 300/400/500h are included within this database with the newer models currently being assessed, expectant to be included in the database also.
This database was created to support UK building energy performance assessments that are produced using the National Calculation Methodologies for energy rating buildings (NCMs). The NCMs are a range of assessment methodologies comprising: the Standard Assessment Procedure for Energy Rating of Dwellings (SAP), Reduced Data SAP (RdSAP), which is used to assess existing dwellings, and the Simplified Building Energy Model (SBEM)*, which is used to assess non-domestic buildings. The website also supports assessments undertaken using the BREDEM (BRE Domestic Energy Model) assessment methodology, the parent methodology upon which SAP and RdSAP are based.
Building energy assessment methodologies are used to deliver multiple Government policy initiatives. These range from Building Regulation compliance checks and the production of Energy Performance Certificates, which satisfy the UK’s obligations under the European Performance of Buildings Directive (EPBD), to supporting the Green Deal and Energy Companies Obligation (ECO) schemes by enabling the differentiation of improvements measures. Assessing the performance of a measure is complex and it may not always be possible to describe in terms of a simple number for comparison purposes. In such instances the assessment of performance is only possible using building energy performance assessments that utilise specific product performance data.
