Inquiry

5. ASHRAE 90.1-1999 vs. local energy code. We are required to show compliance with the Model National Energy Building Code (MNECB) as part of the application process for the Commercial Building Incentive Program (CBIP). This program is offered by Natural Resources Canada to promote energy efficient design in new and renovated existing buildings. We have to use the Performance Path Method, which is similar to the Energy Cost Budget method in that simulations of both the proposed design and a Reference building are performed to compare energy results. Our goal is to better the MNECB Reference model by 25% to qualify for a CBIP funding. At first glance, both codes would appear to be as demanding. There are differences in the codes but where one is stricter in an area, the other is stricter in other areas. A model of both base buildings would be required to accurately determine which is stricter. What is your recommendation?
