Mobile and Manufactured Housing Market Characterization
Assessing the landscape of energy efficiency programs available to mobile and manufactured housing (MH) in Vermont, this research offers recommendations around customer engagement, funding and financing, and workforce capacity to better serve MH customers.
Heating Pattern Cluster Analysis of Winter AMI Data
Targeted approaches are needed to help transition customers from price-volatile fossil fuels to more efficient and regulated electricity for heating and cooling. Analyzing energy use patterns alongside cold temperature data revealed likely ideal candidates for electrification programs.
Energy Resilience Planning Framework
Efficiency Vermont surveyed existing resources to develop a shared definition of energy resilience suitable for Vermont that can guide planners through a comprehensive strategy to prepare for, adapt to, and recover from energy disruptions.
2024 Vermont Heat Pump Market Assessment
This Market Assessment investigates the status of heat pump technology, availability, accessibility, and adoption in Vermont as of fall 2024. The assessment includes cold-climate heat pumps used for space heating and cooling, and heat pump water heaters, with a focus on the residential market.
Load Shape Segmentation for Better Grid Stability and Increased Customer Benefit
Utilizing advanced metering infrastructure (AMI) data, this research project demonstrated that the use of load clustering can help identify typical load patterns within a population, revealing use patterns well-suited for certain efficiency measures or programs.
Industrialized Weatherization: Comprehensive Deep Energy Retrofits with Prefabricated Panel Block Wall Insulation
This research project offers a possible prototype for achieving Vermont’s building weatherization goals by evaluating a super-insulated wall retrofitting process using prefabricated panel block wall insulation, a form of industrialized weatherization or industrialized construction developed by the Fraunhofer USA Center for Manufacturing Innovation.
Evaluating Equity and Justice Impacts of Energy Efficiency Projects
This research project sought to determine which energy equity metrics could provide the greatest insight into equitable program design, and recommended strategies to address equity in both C&I and residential markets.
Enhancing Carbon Reduction Estimation: A Time-Centric Analysis of Vermont's Clean Energy Programs
Vermont’s clean energy program efforts now include transitioning fossil fuel energy use onto an increasingly renewable electric grid and shifting energy time of use to periods where renewable energy is most abundant. Quantifying carbon reduction as a result of these efforts might require greater consideration for the time component of energy use.
Efficiency Vermont’s Approach to Energy Resilience
As the energy industry undergoes a rapid increase in the use of renewable energy, Efficiency Vermont is supporting customers and Vermont’s energy system in achieving resilience.
2023 Focused Communities Key Findings
Learn how Efficiency Vermont is making energy-saving tips easy to understand for everyone, no matter what language they speak. Find out about our new efforts to make our services accessible to all Vermonters.
Vermont's 2023 Energy Burden Report
Vermonters spend, on average, 11 percent of their household income on energy. That’s more than one in every ten dollars spent on heating, driving, and keeping the lights on.
Evaluating Equity and Justice Impacts of Energy Efficiency Projects
Researchers looked at equality, equity and justice in energy efficiency projects, and identified ways to capture the broader societal impacts of efficiency efforts to both boost equitable outcomes and foster thriving communities.
Energy Resilience: Three Multi-Year Energy Resilience Demonstration Projects
This paper evaluated three Efficiency Vermont demonstration projects around energy resilience: a microgrid in a housing complex, heating/cooling projects using phase change materials, and modeling around indoor temperature change after a power outage. Insights from this evaluation can inform design and construction professionals, as well as regulators, about the most cost-effective ways to implement resilience, from simple and inexpensive options to expensive projects.
Greenhouse Gas Reduction: Simulating Grid Effects of EVs, Batteries and Solar in Vermont
A computer model simulated a Vermont neighborhood of about 100 homes with different amounts of solar panels, electric vehicles, and in-home batteries. These distributed energy resources (DERs) can have beneficial effects for the grid, and help manage increased energy loads without expensive infrastructure investments.
Resilience: The Role of Energy Storage in Meeting Vermont’s Energy Goals
Utility-scale batteries and other long-duration energy storage technology will need to be deployed on a large scale to stabilize Vermont's grid and meet demand when renewables like solar and wind are intermittent. Comprehensive planning with regional grid partners is necessary if all forms of energy storage are to work in concert to meet the needs of the grid.
Greenhouse Gas Reduction: Residential Rate Calculator
Could alternative electricity rates save customers money? This paper used a rate calculator and found that variable rates can in fact lower costs with no change in customer behavior. Utilities could use such a calculator to manage the electrical grid by incentivizing customers to use less or more energy at specific times.
Greenhouse Gas Reduction: Delivering Value to Commercial Customers with Load Shape Segmentation
Advanced meter data and analysis can identify commercial operations with similar energy use patterns, pinpointing untapped savings and finding customers well-suited to efficiency programs—delivering both savings and grid benefits.
Comfortable, Healthy, and Saving Money: Linking Building Occupants’ Health to Energy Efficiency Programs
Healthcare payers, like hospitals and health insurers, could leverage "energy plus health" strategies that realize health benefits from energy efficiency projects. Similarly, government institutions and philanthropic organizations could support vulnerable or marginalized communities and businesses with programs that reduce air pollution, improve indoor air quality, and boost housing safety and affordability through initiatives that consider both energy efficiency and health outcomes.
Embodied and Operational Emissions in Retrofitting Vermont Homes
What's the "Carbon Smart" approach to weatherization?
Healthy Homes Vermont 2021
Efficiency Vermont collaborated with regional hospitals and the Vermont Weatherization Assistance Program (WAP) to deliver energy-plus-health services to low-income households.
