DiscoverEE Webinars: Air Sealing De-Mystified: A Custom Calculator That Instantly Measures and Evaluates Energy Savings

April 14, 2023 @ 12:00 pm - 1:00 pm

Every house needs to breathe, hence builders have to allow a certain amount of infiltration or even better provide a mechanical ventilation system that brings in fresh air.

However, as the house gets older it becomes leakier.

Listeners would be quite aware of the fact that the current methodology used to quantify energy losses associated with air leaks in a house is through HOT2000 only. The whole house is modelled with the software, then blower door tests are conducted and the results processed through HOT2000 to generate an Energuide report which also contains infiltration losses.

And to evaluate energy savings from air sealing, they’ll have to conduct the modelling twice and this is time consuming and costly.

Now, they’ll be happy to learn that a full Energuide audit will not be required anymore. Summerhill will be presenting this tool which is also available in an app. All they need to do is collect the blower door test data and some parameters from the house and input into the calculator. Results, specific to infiltration only, are instantaneously generated.

With this tool, the process of guided air sealing becomes much easier and simpler.

Utilities can consider this as a great tool for a performance-based air sealing program.

On the other hand, new home builders, renovators, insulation contractors can use these to demonstrate the effectiveness of their air sealing work, kind of a QA. The whole testing process including generation of results will take no more than 30 minutes.
