The importance of a fresh air intake vent. Does your building or home have a fresh air intake vent? Would you know if it did? The tell-tale openings can be found on the building envelope, hopefully at least 10-feet away from contaminant sources. If you place a hand by...
Participating in the practice of hot yoga is a challenge not only for the practitioner, but for the building owner who needs to control the humidity under the required temperatures. The ideal climate for a hot yoga studio is a temperature of 40.5 C (105 F) and 40 percent humidity. Keeping a healthy, mold-free environment with good IAQ is more of a challenge in some geographic locations than others.
If you were offered a 50%-off coupon or a 75%-off coupon while shopping, which would you choose? If you knew you had the option to breathe far cleaner air and improve your day-to-day cognitive skills rather drastically, would you say, “No, that’s okay”’ or “Where do I...
Many people think of energy-efficient savings first when planning to meet ENERGYSTAR®, LEED, or Passive House Institute standards and consider health benefits an added extra. However, as we said in a recent article on The International WELL Building Institute’s WELL Building Standard, buildings without superior ventilation contribute to sluggish performance, less astute thinking, and more sick days.
Since BPE ERVs are modular, they can be stacked to produce fresh air requirements ups to 20,000 cfm. Such modules are man-portable, will fit through a 36-inch door, and can be assembled by two men in four hours.
Depending on the publication or organization you consult, our atmosphere has sucked up enough energy-related emissions to bring us near, at, or past a point of no return where rising sea levels, heightened temperatures, and poor air quality wreak havoc on everything from weather to life itself.
Building Performance Equipment, Inc. welcomes the newest addition to its family of Energy Recovery Ventilators (ERVs)–and it’s a rather special little guy. Like its bigger brothers, the BPE-XE-MIR-200-i is an ultra-energy-efficient unit that sports a counter-flow heat exchanger design with less than 1% mixing of air streams. Ultra-as in 80% to 98% thermal efficiency with an Energy Efficiency Rating (EER) of 60 to 160. (Most ERVs in the industry typically come in at 45% to 65% thermal efficiency, rarely surpassing an EER of 10.) The new unit works much like the rest of the multi-patented line as it preconditions incoming air to room temperature. In other words, it efficiently recovers energy from stale air leaving the building and uses it to warm room temperature in colder months and cool it during the warmer months. In fact, BPE ERVs are so efficient that they, depending on the situation, can actually reduce or eliminate the need for supplemental HVAC. That efficiency can also reduce energy bills and our impact on the environment. In fact, it is LEED approved and ideal for Passive House design as well as conventional.
When school buildings choose clean energy retrofits, many of the benefits are obvious. Others not so much. Improved Indoor Air Quality does more than provide healthier learning environments: Public schools rely on average daily attendance rates to receive federal funding, so the potential for less student and staff sick days is important.
Rarely, can you call someone or something ‘passive’ and have it come off as a compliment. Inactivity, especially in today’s society, comes off as just plain lazy in most circles. Oddly enough, adopting passive methods to power our homes just
might ignite the fastest, most powerful sprint toward a net-zero building stock. Passive energy practices cut back on energy use by 80%, ease harmful emissions, reduce reliance on the grid, save heaps of money, and offer the population far healthier indoor air quality (IAQ).
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.
