Team Catalyst works with building designers to optimise the building envelope design in terms of daylighting, thermal comfort, indoor environmental quality and energy efficiency.
We also carry out BCA (NCC) Section-J compliance calculations for the whole building envelope using either Deemed-To-Satisfy (DTS) or the Alternate Verification JV3 energy simulation method. The JV3 method allows for performance trade-offs between building envelope elements, that is between glazing, framing, shading, insulation and thermal mass. This process allows for architectural design flexibility.
Team Catalyst have expertise in calculating the solar, thermal and optical performance for window systems and curtain walls. These values are required for BCA (NCC) Section-J2 and J1 compliance calculations.
