There is a formula for calculating heating Btu and a formula for calculating cooling Btu. Both of these formulas have three components necessary to complete the calculations. Two of the Btu formula components are field measured while the third is a multiplier that is added at the end of the formula.

The following five projects demonstrate how contractors are working closely with customers to provide personalized, effective, and efficient IAQ solutions.

Building codes and increasingly educated consumers who understand the benefits of proper ventilation are driving innovation in the ventilation market.

With model building codes mandating tighter and tighter ductwork, and with homeowners and building owners desiring increasingly higher efficiencies from their ducted systems, many new products have hit the market to help builders and installers efficiently and effectively meet those requirements. 

The Delta Breez ventilation fan is designed to deliver a ventilation solution that consumes less power with advanced functionality and quiet operation. 

The SkeleCore Pull-Tight™ has been added to the company’s SkeleCore™ line of internal framework systems for fabric duct air dispersion.

Semco LLC showcased its Unitary Wheel Cassette (UWC) Series, a sensible and latent energy recovery aluminum desiccant wheel. 

A couple of months ago, I addressed the topic of how proper HVAC system design could not guarantee the installed performance of a system. Since that article, I have received a number of emails requesting I go into further detail about the measurements I mentioned and how to verify the installed performance of a system.
