The Evidence of Suitability method using the Deemed to Satisfy Provisions of Part J of the Energy Efficiency section of the NCC Volume 1 (formally the BCA) have been chosen as the most appropriate method to assess the compliance of the proposed development.
The performance requirements of the Deemed to Satisfy provisions include but are not limited to meeting the Total R-Values of roofs, walls and floors, the glazing allowances and the air movement requirements. These detailed provisions also include the testing and installation of insulation, thermal breaks, compensation for downlights, floor edge insulation and detailed provisions for building sealing. These requirements fall into nine main sections in the NCC:
Part J0 - Energy Efficiency (J0.1 to J0.3) and Part J1 - Building Fabric (J1.1 to J1.6) and Part J2 - Glazing (J2.1 to J2.5) and Part J3 - Building Sealing (J3.1 to J3.7) and Part J4 - Air Movement (not applicable) Part J5 - Air-conditioning and Ventilation Systems (J5.1 to J5.4) and Part J6 - Artificial Lighting and Power (J6.1 to J6.6) and Part J7 - Heated Water Supply and Swimming Pool and Spa Pool Plant (J7.1 to J7.4) and Part J8 - Facilities for Energy Monitoring (J8.1 to J8.3)
In your Section J report, we will identify how the new building works comply with the said Deemed to Satisfy provisions.
