Multi-Campus Energy Savings: A West Coast Health System
Eneration’s Approach
- Analyzed three years of utility data across all facilities.
- Prioritized buildings based on savings and energy reduction opportunities.
- Performed an energy checkup to identify Energy Conservation Measures (ECMs).
- Prioritized ECMs based on impact and payback to advance the highest value opportunities.
Key Outcomes
- ECMs identified: 75
-kWh reduction: 5,377,500
- Therm reduction: 229,380
- Annual savings calculated: $1,386,050
- Estimated cost: $4,273,400
- Simple payback: 3.1 years
To help a West Coast health system achieve its goals of increasing sustainability and reducing operational costs, the Eneration team implemented a strategic prioritization process across several campuses and buildings to identify the most impactful opportunities for energy reduction. By focusing on the top three prioritized buildings, Eneration uncovered over 70 unique Energy Conservation Measures (ECMs) that allow the system to capitalize on significant financial and environmental returns. These improvements are projected to reduce the healthcare system's annual energy bill by $1.3 million, roughly 40 percent of its total energy costs, while eliminating over 5,000 metric tons of CO2 from the atmosphere.
THE ENVIRONMENTAL IMPACT
Energy savings that go beyond the bottom line: 75 metric tons of CO2 eliminated each year, equal to removing 958 cars from the road, planting 1,068 acres of forest, or powering 426 homes.
Energy Efficiency Benchmarking and Savings Potential
The Eneration team analyzed three years of utility data for all facilities to identify where energy savings would be most impactful. Buildings were prioritized based on energy spend and energy use intensity (EUI) compared to the average hospital and clinic in the same climate zone. The three highest-opportunity buildings were selected for a full energy checkup.
In the chart, green hexagons mark the three chosen buildings. Green bars represent each building's energy spend, while blue bars indicate the building's energy use intensity (EUI) compared to the average hospital and clinic in the same climate zone, shown as blue and orange dashed lines.
