Every month this section features must-read content from past newsletters – just in case you missed it.

Heat Recovery Ventilation System Design Considerations

Achieving reliable ventilation in relatively tight homes requires a balanced system. While there are multiple ways to achieve balanced ventilation strategies in residential new construction, heat recovery ventilators, or HRVs, are the optimal home balanced ventilation system for tight homes in the Northwest. Energy recovery ventilators, or ERVs, may be better suited for cold climates and higher elevations. The Heat Recovery Ventilation System Design Considerations factsheet provides tips and recommendations to make the most of your HRV installation. Unless properly designed, installed, and operated, an HRV may be no more energy efficient than a pair of exhaust fans.

BetterBuiltNW Publishes Additional Ductless Heat Pump Resources

Resources are newly available on the BetterBuiltNW website about ductless heat pumps for installers and builders. These resources were originally developed by the NW Ductless Heat Pump Project (which will be retired in April 2022).

The resources explain installation best practices and how to maximize efficiency, especially in cold climates. Note, in addition to the articles referenced below, BetterBuiltNW published the first two articles in the January newsletter and two more in February.
