When it comes to comfortable, healthy Indoor Air Quality, reliable HVAC solutions must compensate for increasingly tight building envelopes. The trend toward tighter envelopes is, no doubt, an important one. They are a must for keeping out moisture, condensation, and soil gases (i.e. radon) as well as reducing heat and air conditioning costs. However, a supply of fresh air coming into a space is vital if you, quite simply, want occupants to breathe. Further, you want them breathing healthy air. The tighter the envelope, the less fresh air makes it into the building naturally.
The World Green Building Council claims the planet needs to engineer a net zero carbon building stock by 2050 to keep the global temperature increase below 2°C. Scientists believe doing so will prevent the most serious consequences of climate change such as disruption of the world’s food supply and flooding of coastal areas. If the world manages to make all new construction net zero by 2030 and older structures retrofit compliant by 2050, will it be enough to help the planet self-correct? Is keeping the temperature increase below 2°C even feasible?
It’s easy to ignore things we cannot see. Gravity, oxygen, atoms fall into this category … all good things our bodies make use of daily. If these concepts ceased to exist, so would we. Yet we don’t think about that often, nor is it necessary for the average person to do so. Likewise–and unfortunately–we tend to ignore less-beneficial invisible realities such as poisonous elements that collect in our indoor environments and irritate or endanger our bodies. Sometimes we even ignore stinky toxins if the smell is bearable enough. If your home or work environment’s HVAC system is not spitting out bad air and filtering in fresh air optimally, chances are you’re inhaling damaging elements just as sure as gravity is keeping your feet on the ground. And that’s someone everyone should think about.
He’s busy. She’s busy. You’re busy. We’re all busy, and sometimes in this world where information is increasingly at our fingertips, the result becomes overwhelmingly counterproductive. Do you really have time to research the pros and cons for five brands of sunblock when your car battery just died again and you leave for vacation tomorrow?
When we bust ERV myths at BPE, Inc., we aren’t just talking theory. We have demonstrated what today’s super-efficient ERVs can do in the real world. After discussing cross-contamination, efficiency myths, and a case study that demonstrates the excellent IAQ benefits of an ERV in a practical application, we move on to our next ERV myth:
MYTH: “ERVs installations are difficult and complicated.”
When we bust ERV myths at BPE, Inc., we aren’t just talking theory. We have demonstrated what today’s super-efficient ERVs can do in the real world. After discussing cross-contamination and efficiency myths over the last two weeks, we present a case study that demonstrates the excellent IAQ benefits of an ERV in a practical application:
Part of what we do at BPE, Inc. involves busting myths that prevent folks from ruling out the very thing that can improve Indoor Air Quality (IAQ) and comfort, heating and cooling bills, and health. Last week, we tackled the issue of cross contamination in ERVs. This week, let’s dive into efficiency:
Myth Two: “What good is an ERV if the word on the street says they are, on average, only 55% efficient?”
It is the plight of professionals in most industries: You introduce your company to potential clients only to discover their perception of your product or concept has already been influenced by myths or outdated information. It’s no different for the sales force at BPE, Inc. when we explain how Energy Recovery Ventilators (ERVs) are the cost-effective answer for bringing fresh, preconditioned air into buildings and homes so airtight we think of them as Tupperware containers. Therefore, part of what we do involves busting myths that prevent folks from ruling out the very thing that can improve Indoor Air Quality (IAQ) and comfort, heating and cooling bills, and health. Let’s start dismantling some of the myths surrounding ERVs with an oldie but a goodie:
The following case study was undertaken by Klas Haglid in his 7,000-plus-sq.ft. New Jersey home to determine how much of a risk radon levels play in his family’s life. He wanted to see how far he could lower the levels and therefore cut the risk of radon-induced lung cancer proportionately.
Background: To ensure proper radon control, you need continual monitoring and a proper mitigation strategy. If you think the decent radon levels next door are good enough for you, think again. Your neighbor’s numbers have little to do with the levels in your home, so you can’t use generally low levels in your area to claim you are safe
After radon was recognized as the culprit causing high rates of lung cancer in miners, most folks in the construction, realty, and engineering industries came to realize radon gas-a radioactive substance–is not our friend when it comes to indoor living. Still, the grim stats on radon-induced lung cancer deaths and the public’s poor understanding of the problem recently left our Indoor Air Quality experts at BPE, quite frankly, exasperated.
