Weatherization Workforce Plan
A report to the Vermont General Assembly on the coordinated delivery of a standardized statewide building sciences curriculum
Healthy Homes Vermont 2020
Many Vermonters in low-income households are at a greater risk of health problems than are high-income households. Collectively the partners are testing innovative energy-plus-health collaboration pilots and whether these models may be scaled to a cost-effective component of energy efficiency programs statewide. This report addresses the progress achieved in 2020.
Healthy Buildings Vermont 2020
A building’s design and how it operates directly affect occupant health and well-being. Efficiency Vermont has a long history of helping facility managers and building owners make critical energy efficiency decisions—but what impact do these decisions have on indoor air quality (IAQ) and occupant health?
What’s going on in there? Interpretable Machine Learning for Deeper Energy Savings
Efficiency Vermont set out to learn if and how explainable artificial intelligence (XAI)2 approaches could drive adoption of cutting-edge machine learning models for energy modeling at customer facilities.
Phase Change Materials in Refrigeration
Phase change materials (PCMs) are a nascent technology that store heat by virtue of their chemical makeup. How might PCMs be applicable to future energy efficiency work in Vermont?
Lifecycle GHG Impacts of C&I Heat Pump Applications in Vermont
This study provides a method for capturing broader greenhouse gas (GHG) impacts of heat pumps when used to supplement existing fossil fuel heating sources in commercial and industrial buildings.
The high greenhouse gas price tag on residential building materials
This paper quantifies the global warming potential (GWP) impacts of alternatives to common building materials used in residential new construction in Vermont and applies the results of the analysis to actual projects slated for construction.
Energy Resilience Return on Investment
How do you put a price on energy resilience? This paper proposes formulas and variables necessary to do that, helping customer determine the best return on their investment in energy resilience assets.
Research & Development 2019-2020 Final Report for PowerShift
Efficiency Vermont has investigated the practical strategies for achieving grid benefits from flexible load management, through its Project PowerShift.
Embodied Carbon in Vermont Residential Retrofits
This paper fills the gap in the data on the embodied-carbon (lifecycle carbon footprint) contribution of weatherization materials in Vermont retrofit projects, helping residents and trade professionals better understand the climate change impacts of the building materials they select when weatherizing existing homes.
Interim Report for PowerShift
This paper reports on interim findings and progress of a two-year partnership between Efficiency Vermont and Washington Electric Co-op to demonstrate the potential for water heaters to function as “virtual batteries” in a residentially-focused utility service territory with low population density.
2019 Greenhouse Gas Taskforce
An expert assessment of six new greenhouse gas reduction strategies related to energy efficiency.
Healthy Homes Vermont 2019
This paper reports on three pilots designed to test how a collaboration among health care providers, weatherization programs, community service providers, and Efficiency Vermont can deliver an energy-plus-health service approach to improve housing quality, indoor air quality, and customer health.
Peak Response Program: 2018-2019 Demand Response Capability Initiative
This study examines the extent to which a single, medium-sized customer could shed and shift load during the summer peak season, using the Efficiency Vermont office space and staff as the test customer on the Burlington Electric Department system.
Vermont’s Total Energy Burden by Town
Understanding energy burden, the ratio of energy spending expressed as a percentage of household income, is a powerful way to gauge the impact of energy costs on Vermonters. Energy costs are a significant burden on many Vermont households, competing with other priorities such as housing, healthcare, and food. Energy burden data can inform state energy programs to ensure households with high energy burdens have access to programs that can reduce energy costs and burden.
Keep It Cool: Real-time Monitoring of Convenience Store Refrigeration Systems
Energy efficiency programs’ commercial customers frequently follow a business model of responding to needs, especially operational needs, as they arise. But what happens when those customers’ business objectives could shift from a responsive—or more accurately, reactive—service model to a proactive one? This study shows the benefits to customers when they adopt this approach.
Healthy Homes Vermont 2018
The nexus between building energy efficiency and better health is now becoming the target for improving housing conditions for vulnerable populations. This report offers a story of pilot projects under the new Vermont Healthy Homes Program.
Assessment of Demand Response Capability and Effectiveness
This study investigates where existing efficiency program activities might complement existing distribution utility-led demand-response services.
What Are the Limits of AMI in Supporting Load Management?
This study applies AMI interval data to better understand the effects of energy efficiency on regional grid operations across long periods of time.
The Value of Efficiency: Renewable Ramp Challenge
As the electricity grid increasingly accommodates solar electricity, a problem is emerging: At sunset, non-solar sources of electricity must quickly ramp up. This limits choices for power plants providing the post-sunset electricity and is difficult for traditional power grids to accommodate. In this study, Efficiency Vermont analyzed the effectiveness of specific energy-efficient equipment upgrades in flattening the loads of Vermont businesses and residences.
