Episode 5: The Juiciness of Decarbonizing Domestic Hot Water with Neil Donnelly & Charlie Simek
Join hosts Alina Michelewicz and Michelle Moran for their deep-dive into hot water. In this episode, Neil Donnelly and Charlie Simek, Energy Engineers at New Ecology specializing in data-focused decarbonization planning and building system optimization, follow up on their recent NESEA BuildingEnergy Boston presentation, “Equitable, Data Driven, Domestic Hot Water Decarbonization” to show how real data from real buildings can guide more efficient and lower-cost systems when its time to replace them. We explore the opportunities within recently monitored domestic hot water systems and the steps for owners, operators, engineers and utility program administrators. This episode was made possible by a Mass Save Community Education Grant.
