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.”

AIA Redwood City Balanced Ventilation Event

On June 20, Hayward hosted the American Architects’ Institute (AIA) of San Mateo County and members of the Passive House community for presentations from Dr. Kara Rosemeier and Bill Hayward on “Balanced Ventilation in Passive Houses.” The event, which took place Hayward’s Redwood City facility focused not only on the critical roles air tightness and balanced ventilation play in passive houses, but also on how they work together to provide the foundation for a healthy home by ensuring superior indoor air quality.

Dr. Rosemeier is an expert in ventilation for residential buildings, with a special focus on healthy and affordable housing in New Zealand. She is the chair of the Passive House Institute New Zealand and teaches part-time at the architecture department of Unitec in Auckland.  She was in the Bay Area as part of a North American organized by the North American Passive House Network and hosted locally by Passive House California.

Dr. Rosemeier spoke about how to design an efficient residential ventilation system. Her presentation covered the role of an airtight thermal envelope in ensuring good indoor air quality, the importance of continuous air exchange, and the advantages and disadvantages of different options for continuous ventilation.  She also covered typical layouts and design challenges of heat recovery ventilation systems.

Bill Hayward is CEO of Hayward and founder of Hayward Healthy Home. Eight years ago, he set out to discover what about his family’s dream home was making them all sick. The result? A realization that indoor air quality was paramount to good health and a set of four principles to ensure that every home could be a healthy home. Recognizing that many elements of a passive house, which not only lower energy consumption but also provide superior comfort, indoor air quality, and resilience, supported his ideas about a healthy home, he decided incorporate those elements into his home as well.

Since the home was completed almost two years ago, four separate indoor air quality studies have been done. Analysis of the data resulted in several thought-provoking conclusions including:

  • There are far more chemicals, particles and VOC’s (volatile organic compounds) found in new houses than expected, even when non-toxic, no-to-low VOC, and other “green” products are used exclusively;
  • Higher ventilation rates in the first 12 months after construction are needed to protect occupants from off-gassing and may be necessary longer-term depending on occupancy, behaviors, and personal sensitivities;
  • Air tightness, a key component of passive houses, needs to be offset by a balanced ventilation system in order to optimize health.

In addition, Mr. Hayward presented data from “The Impact of Green Buildings on Cognitive Function,” a new study from the Harvard T.H. Chan School of Public Health’s Center for Health and the Global Environment, that found that improved indoor environmental quality doubled occupants’ cognitive function test scores.

All in all, the evening provided the attendees with a lot of new information about the role of ventilation in home design and why air tightness and balanced ventilation is critical for building healthy homes.

Hayward Healthy Home Featured in the Monterey County Weekly

Hayward Healthy Home Featured in the Monterey Weekly

Hayward Healthy Home was recently featured in the Monterey County Weekly, in order to inform more people about the dangers of an unhealthy home.  This magazine article continues to get the word out about Bill Hayward’s personal experience with a mold infested home and how he responded to protect his family’s health and his own.  Bill Hayward founded Hayward Healthy Home to educate people on what to look for in their personal homes that may be promoting poor health.  His premise, which drives Hayward Healthy Home, is that home should promote good health rather than create poor health in their occupants.

Sinus congestion, coughing, mood swings, headaches and fatigue are all common health concerns that may actually be caused by the poor air quality inside of a home!  The article brought out how Hayward Healthy Home is dedicated to improving the quality of indoor air by using eco-friendly building techniques and products to implement its four principles for a healthy home.  For example, Zehnder fresh air machines deliver continuous fresh air inside of a home, which can drastically improve the air quality, and therefore the health of your home.

Hayward Healthy Home is now launching Ahhm, a radiant heating and cooling system built into the ceiling panels of a home.  This device heats more quickly and offers more control over important comfort factors such as moisture, air circulation, and humidity than either traditional forced air heating or floor based radiant heating.  It also cools a home, in addition to heating it.  Along with the already popular Zehnder fresh air machine, Ahhm will be another great option for individuals who want the ultimate in indoor comfort and who recognize the importance of indoor air quality.

The article also discussed another innovative advancement in building envelope technology, which Hayward Healthy Home is developing in partnership with View Dynamic Glass.  Hayward Healthy Home will pioneer the distribution of this new “smart windows” technology into single family homes.  These windows will permit home owners to easily control glare and the amount of sunlight entering their house with just the touch of a button on a phone or tablet.  Dynamic Glass technology has already been proven in commercial buildings, and it has several advantages over typical windows including reducing sun glare and heat during peak sunlight hours and significantly reducing annual energy costs.  Proper sealing and insulation is a second principle for a Hayward Healthy Home.

Hayward Healthy Home builds on Hayward’s long standing commitment to promoting “green” products that are better for the environment.  Hayward Healthy Home wants to promote building houses where both human health and comfort and environmental consciousness is a priority.  This is consistent with the third principle of building a healthy home: minimizing toxic materials.  We highly recommend reading the recent article released about our company to learn more about how you can personally benefit.  The article contains health risk statistics and other vital information for making your home a safe haven.
