Health care does tremendous good, but the industry is also one of the highest contributors to greenhouse gas emissions and air pollutants.
After a successful sustainability pilot program at Maine Medical Center, MaineHealth leadership decided to incorporate environmental sustainability into the system-wide strategic plan and set a five-year target of reducing greenhouse gas emissions by 25%. Working towards this target in 2023, 12 facilities that provide acute care to patients across the MaineHealth service area received environmental sustainability audits.
“Hospitals and inpatient care settings account for nearly 75% of all energy consumption in health care facilities. Prioritizing building audits with the highest energy consumption was a good place to start.”
– Mike Arsnow, MaineHealth Sustainability Manager
MaineHealth partnered with energy efficiency company Ameresco, whose teams conducted the audits. Three teams focused on energy (weatherization, lighting conditions and HVAC), and one evaluated water efficiency. Following the inspections, Ameresco reviewed each building’s historical utilities data and is now quantifying the impact of potential efficiency upgrades from a financial and environmental standpoint. Key stakeholders will review proposed energy and water conservation measures before implementation begins.
