Popular Multifamily Retrofits, Pt III

SWA_MF_energy_storage_systems

In the first two entries of this series (Part One | Part Two), we explored advanced controls for electrically heated buildings; combined heat and power systems; upgraded atmospheric boilers and ventilation systems. For the final installment of SWA’s Favorite Multifamily Retrofits, we’ll examine the ins-and-outs of stand-alone energy storage. Read more

It Can Take Years – A Market Adoption Story

Earlier this year, at the AHR Expo in Orlando, the biggest trade show for HVAC professionals, Aeroseal’s duct sealing technology was declared the Product of the Year, the top honor of the Innovation Awards. Aeroseal was recognized as “a groundbreaking solution to an industry-wide problem.”

The unique appeal of the Aeroseal technology is that it seals ducts from the inside. Walls and ceilings do not need to be removed or damaged to gain access for traditional mastic sealing. Aerosolized vinyl polymer particles from 2 to 20 micrometers are injected into a pressurized duct system. The particles stay suspended in the air stream until they reach the leaks, where they are deposited and built up at the leak edges until the leaks are sealed.

The Aeroseal technology has been around for more than two decades. It was developed at Lawrence Berkeley National Laboratory in the early nineties and patented in 1997. It has received many awards over the years including the Best of What’s New award from Popular Science magazine in 1996 and the Energy 100 award from the U.S. Department of Energy.

So what’s the big deal?

In our first entry of this three-part series, we described advanced controls for electrically heated buildings, combined heat and power systems, and upgraded atmospheric boilers. This time around, we’ll examine the ins-and-outs of exhaust ventilation in multifamily buildings. Read more

Popular Multifamily Retrofits, Part I

SWA_Multifamily_Retrofits

There is no single retrofit that is a panacea for all multifamily buildings. There are myriad options and permutations for upgrades, the efficacy of which is defined by the operational needs, budget, and goals set by the owner. With that in mind, we will examine six retrofits popular with SWA clients in this three-part blog series. Read more

Game Changers in Building Science

Thank you to everyone who stopped by our booth last week at Greenbuild 2015 in Washington, D.C.! By all accounts, this year’s event was a great success. In case you missed it, our fearless leader, Steven Winter, spoke at the GAF booth on Wednesday. As an architect who has been practicing building science for the past 50 years, he shared insights about some building science innovations that he thinks have been “game changers” and have intrigued him: they are changing the way we design, build and operate buildings.
