Adsorbent air cleaning: a new way to think about commercial ventilation

Do adsorbent air cleaning systems deliver on all that they claim? We test them to find out. Over the past four decades, technology and engineering practices have made enormous strides in lowering the energy use of buildings. However, there is an area of building operations that remains a persistently high energy user: ventilation. Continue reading

City of Providence building energy code compliance process review

Code compliance: the only path to energy savings from advanced codes Many cities lean on advanced building energy codes to meet climate action plan goals. Energy savings that drive reduced emissions and bill savings for businesses and consumers are two great benefits. But are all buildings under construction following code? The City of Providence, RI partnered with Slipstream to find out. Continue reading

Beneficial Electrification with Dual Fuel Home Heating

There are several benefits of dual fuel space heating instead of all-electric space heating. These include resiliency, allowing consumer-members to adapt to changing temperatures, and improving comfort while still providing an opportunity for beneficial electrification. Slipstream’s Justin Margolies contributed to an article titled, “Advancing Beneficial Electrification: The Role of Dual Fuel Home Heating Systems in Cold Climates.” Check it out to learn more about this technology and applications specifically for colder climates.

What utility executives should be thinking about in 2020

There are many ways innovation can disrupt your business–sometimes disruption can be acute; other times, it happens so gradually that by the time you even notice, it might be too late for action. In Energy Central, Slipstream’s Steve Kihm, principal and chief economist, and Karen Weigert, vice president business strategy and regional operations, share stories of businesses impacted by both types of disruption. Learn how these businesses responded, the long-term effects they experienced, and the lessons that utilities can take from their stories. Continue reading

Dust Control Strategies for Energy Upgrades

Dust created during a weatherization job or home performance upgrade is more than just a nuisance—in some cases, it can pose health and safety risks. Effective dust control can protect workers and occupants from lead or asbestos, improve project efficiency, and boost customer satisfaction. Cory Chovanec, Building Science Specialist, shared dust control best practices for the winter 2019 edition of Home Energy Magazine.  Continue reading

Q-Sync motor performance in walk-in coolers and freezers

Q-Sync motors are a new type of innovative, highly efficient and cost-effective, permanent magnet synchronous (PMSM) motor. Between our own field research and the existing literature, studies find that in reach-in and walk-in cooler and freezers, Q-Sync motors cost-effectively use 50% - 80% less energy than traditional shaded-pole (SP) and permanent split capacitor (PSC) motors, and are even more efficient than the newer electronically commutated (EC) motors.

Examining Potential for Prepay

Examining Potential for Prepay as an Energy Efficiency Program in Minnesota

Although prepaid electricity is common in some regions of the world, it is relatively new to the US. But there is a growing interest in finding out whether paying for your electricity use in advance would change or reduce your overall consumption. Could an energy efficiency program capture energy savings simply by changing when you pay your bill from after use to before? Continue reading
