Builder.com’s recent article, Advocating For Fresh Air In Homes, highlights Bill Hayward’s passion for creating a healthy breathing environment in our homes. Written by Jennifer Castenson, the article delves into how Bill Hayward has been in the industry for many years and why he knows fresh air in our homes should be a priority.
In the following statement made by Bill, we can see an evaluation of the building industry and how air quality should be a highlight. ““Homes should come with a warning label,” Hayward states. “Most builders and architects aren’t aware that the normal home concentrates outdoor pollutants inside the house. I have been running Hayward Lumber for 25 years and I didn’t know that. A traditionally built house, due to the way it is built, will concentrate outdoor pollutants. But, home buyers have a choice to put a fresh air system in their home. And, we, as an industry, have a responsibility to educate and support that process.”
““After my family got sick inside our home, I started researching,” Hayward says. “Thirty percent of the population has allergies and is physically affected by the indoor air quality. The worst air that Americans breathe right now is the air within their house.””
The article proceeds on to talk about Bill’s “discoveries” and how they spurned his mission onward to make changes to improve the home building industry. The article quotes him saying, “homes can be improved with two changes: the right ventilation and the right sealing. First, in today’s home construction, ventilation is usually approached by a bathroom fan. The plus side is that a bathroom vent gets rid of the damp, warm air. But, on the other hand, it’s bad because it pushes the warm air into the walls and ducts, where it can then harbor pollutants and help them grow.”
The article also mentions “that it is not just about balancing ventilation supply and exhaust, it’s about tempering the air passively.” So the ventilation is added to the clean the air, and instead of that air mixing with the rest of the air in the room, it should be replacing it. Bill Hayward says that every home should have a high-performance ventilation system, just like any other standard system that homes are built with today.
If your home was built without a ventilation system Bill estimates “that for a 2,500 square foot home it would cost about $12,000 – $15,000” to install a ventilation system. The home building industry is recognizing that having proper air ventilation is important and that “code is starting to respond to these demands.”
With the ventilation of the home now addressed, the article now mentions “the issue of air tightness”. The article continues: “Hayward contends that for wellness and comfort, homes should be built to a 1 ACH (air changes per hour) or lower, which means fewer pollutants and sound entering the cracks. In a 2,500-square-foot house, to get to a 1 ACH would require $1,000 worth of tape, if you have Tyvek. The tape would need to go on all plywood seams and at all sources of air flow.”
The code for this subject is set at a pretty low bar but “Hayward Hopes that builders can focus beyond the code to create air tightness and noise reduction.” Noise reduction is a great benefit to a properly vented home as well.
There are many benefits that coincide with equipping your home with these systems. “There are several cost savings. First from downsizing the HVAC, then from lower risk, and also from the water proofing envelope. Plus, the house performs better and the home builder can reduce reserve per house if they have to hold because of the risk reduction. One of the highest litigation risks in home building right now is home buyer’s illness. So, the ventilation and sealing improvements lead to cost reductions for the builder and also for the consumer over time.”
