Section J

Section J in the NCC code compliance focuses on energy efficiency. It establishes regulations concerning the design of energy-efficient buildings and their systems. The objective is to minimize peak energy consumption, decrease greenhouse gas (GHG) emissions, and ensure occupant comfort. Our services encompass Section J assessments and reports, and we possess expertise in conducting assessments using both the Deemed to Satisfy approach and the J1V3 verification method


J1V3 Solution

When it comes to Section J compliance, we offer a unique approach that includes utilizing the J1V3 method. This method provides flexibility by allowing the redistribution of allowances between different building fabric elements, resulting in reduced overall energy consumption compared to a reference model. Here's how we can assist you with our Section J solutions:

Energy Modelling Con

Energy Modelling

We can perform energy modelling to optimize building design using IES (VE) modelling software. We can provide assistance from the concept stage through to the monitoring stage. All along, we will use analytical method to support our inputs.

Day Light Modelling

Daylight Modelling

We can conduct the daylight modelling using suite of software tools called “Radiance”. Radiance has this unique ability to simulate the behavior of light in complicated designs hence a very useful tool to evaluate new daylighting techniques .



Commercial buildings are required to be energy efficient in order to be an attractive destination for the tenants. The efficiency of the buildings is largely dependent on the design of its fabric and elements as they will outlive the mechanical and electrical systems.
