Paper
There are many advantages to using a heat pump versus another heating and cooling system that uses fossil fuels—even in cold climates. This article, sponsored by Xcel Energy, describes how education, better training, and marketing programs can help heat pumps gain ground in cold climates. Andrew Kotila, Slipstream program manager, shared his recommendations on promoting this advancing technology.
Thank you to Xcel Energy and Building Performance Journal for the opportunity to share this article.

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. More

Paper
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.

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.
