Heat pump space conditioning and water heating can greatly reduce energy consumption compared to existing electric resistance or natural gas combustion options. Requirements for electrical service upgrades add cost and installation delays for customers considering retrofitting heat pumps for space...

Implementing more efficient electric motors can greatly reduce the amount of energy used, save money, and reduce greenhouse gas emissions. Many new electric motor technologies promise higher efficiency, particularly in variable speed applications. However, end-users are reluctant to switch from...

Smart electrical panels, an emerging product category, can provide a number of energy efficiency and electrification benefits to single family residential buildings. These panels replace or augment typical electrical panels and include monitoring and control capabilities of each individual...

This project focuses on the electrification of foodservice hot water. The project will conduct a literature review of commercial kitchen hot water research and data and collect primary data of foodservice facility hot water peak and hourly demand. The objective of this project is to provide data to...

Problem: For residential and commercial consumers seeking to reduce their energy consumption and carbon footprint and to promote a more sustainable future for their local communities and economies, variable frequency drives (VFDs) deliver significant efficiency improvements and a quick return on...

With 40-60 kWh per square foot electric usage intensity (EUI) supermarkets and grocery stores have one of the highest EUIs in the commercial buildings sector. Refrigeration accounts for roughly 50% of the electric energy and furthermore relies largely on Hydrofluorocarbon (HFC) refrigerants with...

The goal of this project is to understand the potential of heat pump rooftop unit (RTU) technology to electrify and decarbonize existing commercial building heating loads. Rooftop units are particularly ripe for market transformation as they are ubiquitous in the commercial sector with decades of...

This project is a demonstration and comparison study between conventional Normalized Metered Energy Consumption (NMEC) analysis and a Measurement & Verification (M&V) method which enhances NMEC with rapid & repeatable interventions. The Enhanced NMEC (E-NMEC) with Rapid Interventions (RI) is...

A limiting factor to rapid adoption of air-source heat pumps (ASHPs) for residential retrofit applications is the first costs associated with installing a heat pump system that provides the home’s full heating and cooling loads with direct distribution into all conditioned rooms of the home. This...
