How To: Adding a CERV to Existing HVAC in a Home
In older homes or buildings where adding new ductwork can be challenging, the CERV2 offers a unique solution by directly interfacing with a central system's ductwork. In this setup, the CERV effectively functions as an air purifier and fresh air injector within the existing HVAC framework.

How To: Install a CERV in a Deep Retrofit Home
Deep retrofits on old homes allow great opportunities to cut utility bills and increase comfort. Insulating and sealing an older home without adding ventilation will most definitely result in indoor air quality and moisture issues, so now is the perfect time to install a CERV!

Smart Ventilation and Smart Air Distribution
Efficiently maintaining a healthy indoor environment is complicated. Automatic control, or “smart ventilation”, is important for meeting a home’s dynamic fresh air requirements while relieving the home occupants’ stress worrying about air quality. Effective distribution of fresh air within a home is essential for ensuring all occupied regions within a home are kept healthy.

Designing Exceptional Homes for Exceptional People
Today’s high performance homes require smart fresh air ventilation and smart comfort conditioning systems that are responsive to the dynamics of human activities. Proper accounting for human ventilation needs and comfort conditioning preferences requires statistical assessments to design homes that are likely to satisfy most people.

Ductology Part 1:
Understand Duct Design & Performance
Understand Duct Design & Performance
How much should a ventilation system’s ductwork cost? And, how can one determine if an installed duct network performs at an acceptable level? We begin a new topic, “Ductology” with a two-part series that explores these questions.

Understand Duct Design & Performance
Part 2 of Ductology focuses on the performance of ventilation ductwork. In this article, we describe two “rough-in” tests that should be performed on installed duct systems before ducts are hidden behind wallboard and ceilings.
