Best Engineering Practices – Ideas for addressing real world ventilation challenges

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.

Concepts in Healthy HVAC

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.

Practical Application of a BPE ERV:

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.

Go Big or Go Home

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.

New Kid on the Block!

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.
