The Deemed to Satisfy method provides a set of prescriptive minimum requirements for the building in order to achieve compliance with the building regulations. This method offers a straightforward approach and we can outline the specific materials, design and construction techniques necessary in order for the building to meet the minimum standards. It’s important to note, this approach may lack flexibility and result in higher building costs compared to alternative performance based compliance solutions (J1V3).

Performance based assessments, also known as 'verification using a reference building', is a method prescribed in the National Construction Code (NCC Volume One) that allows flexibility around design choices involving your building envelope fabric. Instead of following the prescriptive requirements, this approach requires a thermal model to be assessed to demonstrate the proposed building design will perform equal to or better than a reference building that meets the Deemed-to-Satisfy criteria. It relies on computer simulations and modelling to assess the building's performance in terms of energy efficiency, thermal comfort, and other relevant criteria. This method enables a more custom design approach while ensuring compliance with the NCC's performance standards for energy efficiency.

Whether you need a consultants advice to ensure your project meets relevant guidelines, or need additional reports to satisfy planning permit requirements, we can help.

This performance based assessment, also known as 'verification using a reference building', is a method prescribed in the National Construction Code (NCC Volume 2) that allows for much more flexibility around design choices involving your building envelope fabric. Instead of following the prescriptive requirements, this approach requires a thermal model to be assessed to demonstrate the proposed building design will perform equal to or better than a reference building that meets the Deemed-to-Satisfy criteria. It relies on computer simulations and modelling to assess the building's performance in terms of energy efficiency, thermal comfort, and other relevant criteria.
