July 2022 - Research done by Ridgeline Energy Analytics for Efficiency Maine demonstrates that replacing homes’ entire heating systems with heat pumps can deliver comfort and cost savings even in subzero temperatures.. Maine is well on its way to a goal of installing 100,000 heat pumps by 2025.  Energy News Network - In Maine, heat pumps are proving themselves even against extreme cold

June 2022 - Developing a Community-Led Certification Process for Facility Power Outage Resilience: Findings from a Massachusetts Pilot Study With an increase in the climate change-linked frequency and intensity of severe weather events that affect electric distribution infrastructure, there is an urgent need to define power outage resilience and identify methods to assess and certify whether and how planning actions and project implementations have made communities more resilient. Accordingly, the Massachusetts Clean Energy Center initiated the Clean Energy and Resiliency (CLEAR) program to provide technical services to nine community sites in the commonwealth, which formed the basis of a convenience sample for this study. A RAND team—comprising Converge Strategies, XENDEE, and Ridgeline Energy Analytics—conducted stakeholder interviews and a literature review to articulate power outage resilience metrics, piloted a certification program, and used focus groups to assess pathways to the CLEAR program's operationalization and administration.

April 2022 - The Clean Energy and Resiliency (CLEAR) Report evaluated how to provide energy resilience for residential recovery services programs located on the Boston Public Health Commission’s Mattapan Campus to allow the programs’ clients to shelter in place during emergencies. The CLEAR Project Team —Converge Strategies, Ridgeline Energy Analytics, XENDEE Corporation, and RAND Corporation — presents the findings of the energy resilience survey and techno-economic analysis conducted on behalf of the Boston Public Health Commission (BPHC), in partnership with the Boston Planning and Development Agency (BPDA), the Mayor’s Office of Environment, Energy, and Open Space (EEOS), and the Mayor’s Office of Emergency Management (OEM). It provides an overview of the City of Boston’s climate, energy and resilience strategy, and the energy resilience initiatives of the four municipal organizations supporting the CLEAR program.  It then reviews the findings of the energy resilience assessment conducted for BPHC’s Mattapan facilities, including their energy resilience requirements, their existing energy resilience capabilities, and new opportunities  For more information on the CLEAR project visit, the Massachusetts Clean Energy Center.  

November 2021  - The Clean Energy and Resiliency (CLEAR) Report summarizes the findings of the energy resilience analysis conducted for Brigham and Women’s Hospital. The CLEAR Project Team — Converge Strategies, Ridgeline Energy Analytics, XENDEE Corporation, and Rand Corporation — evaluated the energy resilience posture of Brigham and Women’s Hospital to ensure that its lifeline facilities and emergency services are positioned to serve its community when they are most in need.  The report reviews BWH compliance for maintaining reliable power and uninterrupted service in healthcare facilities. It found that BWH is not on track to meet the City of Boston’s zero emissions by 2050 decarbonization target through energy efficiency and building upgrades alone.  The report provides recommendations for BWH to partner with the neighboring residential and institutional partners in the Longwood Medical and Academic Area to make joint clean energy and resilience investments.  For more information on the CLEAR project visit, the Massachusetts Clean Energy Center.  

August 2021 - Ridgeline Energy Analytics and Advanced Building Analytics conducted a baseline energy efficiency study of residential new construction in Maine for the Efficiency Maine Trust.  The Trust sought to understand the level of building code compliance and savings opportunities in home construction. The study examined 127 homes across Maine, 29 of which were manufactured (mobile) homes. Home raters visited each home and recorded a detailed assessment of all home components that contribute to the energy use of the home, including the thermal envelope, heating equipment, lighting, and appliances. The on-site assessments were performed using Home Energy Rating System (HERS) inspections developed by RESNET, Inc. The study team modeled as-built energy use and potential energy savings through increased compliance with codes using REM/Rate and Ekotrope Rater4 software. The study team found that homes built between 2017 and 2020 are more energy efficient than the homes assessed for a 2008 study, showing improvement in code compliance and construction techniques. Many of the new homes had one or more components that did not meet code. According to Laura Martel, Research and Evaluation Manager at the Trust, “The findings of the study indicate that code compliance improves over time as builders become more familiar with the requirements and techniques required to meet them. The Trust sees an opportunity to accelerate that process, with the recent adoption of IECC 2015 statewide, by offering training to builders and code enforcement officers.  The Trust will continue to offer incentives for the most efficient heating equipment for which new homes are eligible. The Trust will focus on whole home space heating solutions for new construction and continue to offer incentives on the most efficient domestic water heating solutions.”

March 2021  - The Clean Energy and Resiliency (CLEAR) Report summarizes the findings of the energy resilience analysis conducted for the Town of West Tisbury and presents ideas for energy resilience upgrades that will support the Town's goals of being 100% renewable by 2040. As an island community, West Tisbury, MA is vulnerable to extreme weather events and the prolonged power outages that they bring. Residents of Martha’s Vineyard cannot easily evacuate during severe weather events. They must shelter in place, making it essential that the town has access to adequate services in times of emergency. Upon identifying possible risks, their most immediate focus is making the town’s buildings more resilient by adopting solar plus storage. Additionally, the island towns have a resolution of shifting to 100% Renewable Energy by 2040. The CLEAR Project Team —Converge Strategies, Ridgeline Energy Analytics, XENDEE Corporation, and RAND Corporation —outlined how the town of West Tisbury can strengthen its energy infrastructure against extreme weather and grid interruptions to ensure that its lifeline facilities and emergency services are positioned to serve its community when they are most in need.  For more information on the CLEAR project visit, the  Massachusetts Clean Energy Center.    

February 2021 - Demand Side Analytics and Ridgeline Energy Analytics performed an impact evaluation of Efficiency Maine Trust's Small Business Initiative lighting program. The program delivers LED lamps, fixture retrofit kits, new fixtures, and controls to small businesses in Maine.  The evaluation assessed projects completed in FY2019 and metered lighting from October 2019 through November 2020. The evaluation found that the program was cost effective under all considered cases. The SBI Program is very influential in transitioning small business lighting to LEDs with a net to gross ratio of 91.4%. Findings from the evaluation will be incorporated into the FY2022 Commercial/Industrial/Multifamily Technical Reference Manual (TRM).
