What is a DTS Assessment?

A deemed to satisfy assessment is a very simple form of energy assessment that simply compares the proposed materials to the minimum requirements stated in the deemed to satisfy provisions in the National Construction Code (NCC).

    When would I use a DTS assessment?

    ​A DTS is an alternative to a 6 star energy rating and can be used for all Residential projects. Typically one would use a DTS report for alterations and additions where only part of a dwelling needs to be assessed or in any other situation where a 6 star rating may be inappropriate.

    How Does the Assessment work?

    The energy rating checksheet will show the proposed insulation and r-values as stated on the plans provided. A total r-value is shown and goal is to be equal to or more than the minimum requirement. If the total r-value is below the minimum stated requirement the energy assessment is classed as failed.

    What are the minimum requirements?

    The minimum insulation requirements differ depending on the climate zone of the proposed site, the materials chosen and construction method. These are outlined in the NCC Volume 2, Part 3.12.
