New Big Deal: LEED Zero

Project teams have relied on LEED (Leadership in Energy and Environmental Design) standards to achieve healthy, cost-effective, and environmentally sound status in green buildings since the U.S. Green Building Council (USGBC) piloted the certification in 1998. Thanks to the third-party verification system, more people have come to understand that sustainable buildings aren’t just good for the planet. Those who build, own, and occupy them reap personal benefits. Let’s face it, we humans like our comfort and we love to save money, so once we hear people gushing over pristine indoor air, lower energy bills, and all-around better living, we all start to want in.

Energy Efficiency Day 2018

October 5th, 2018 marks the third annual Energy Efficiency Day aimed at growing a network of advocates, companies, government agencies, and utilities for the purpose of spreading the news about the benefits of energy efficient practices. How can you take part on a...

Leave the Past Behind

At one point in history, people thought leeches were the answer to illness. There was a time when nobody batted an eye over a pregnant woman dangling a cigarette from her lips. Mercury was applied to cuts and scrapes. Happily, we learned better health practices through the years, didn’t we?

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.

Seeing is Believing

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.

Net-Zero Buildings

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).
