DTS Energy Efficiency Reports (Elemental Provisions)

---

Understanding the Deemed to Satisfy (DTS) Pathway

The National Construction Code provides two primary methods for demonstrating energy efficiency compliance: a 7 Star NatHERS Energy Rating or a Deemed to Satisfy Solution. The DtS pathway is a prescriptive-based approach, essentially functioning as a detailed checklist against the specific, non-negotiable requirements laid out in the NCC.

Unlike a 7 Star energy report, which involves complex thermal performance modelling to generate an overall star rating, a DtS assessment directly verifies that your project’s plans meet or exceed the minimum standards for individual building elements. This prescriptive method avoids abstract modelling in favour of tangible, black-and-white compliance, making it an excellent option for projects where the architectural design can comfortably meet the code’s baseline requirements.

What our DtS Energy Report covers

When you engage Energy Assess for a DtS Energy Report, our accredited assessors conduct a meticulous review of your architectural plans. We methodically check each relevant component of your design against the stringent provisions of the NCC. An official energy report is then produced, documenting clause-by-clause compliance.

Key elements we meticulously assess include:

• Insulation: Verifying that the proposed R-values for walls, ceilings, floors, and any sub-floor structures meet the minimum requirements for your specific climate zone.
• Glazing: Ensuring all windows and glazed doors meet the required U-values (insulating capability) and Solar Heat Gain Coefficients.
• Building Sealing: Checking for appropriate measures for weather sealing, draught-proofing, and fireplace/chimney sealing to prevent unwanted air leakage.
• Lighting: Assessing the artificial lighting plan to ensure it does not exceed the maximum allowable power density.
