Design-Build Energy Savings for Massachusetts
Client
Hogan Regional and Wrentham Developmental Centers. Hogan Regional Center relied on an oil-fired power plant that operated well below peak capacity and efficiency due to age and minimal upkeep. The Wrentham Center was built in 1907 and building infrastructure hadn’t been upgraded in more than 30 years.
Our Tasks
First, we identified a wide range of energy savings opportunities throughout the design-build process and worked to fulfill each one. We upgraded the oil-fired boiler to a new 1,250 horsepower, high-efficiency condenser water boiler plant that reduced system load by almost half. We also installed a cogeneration system and steam heat distribution system at the Wrentham Center to deliver immediate energy savings.
Skills Involved
- Design-Build
- Energy Efficiency
- Project Management
- Boiler Installation
- Cogeneration System
- Energy Management Controls
- Solar Hot Water Systems
Project Results
Our client’s goal was to reduce the environmental impact of their properties over the course of the two-year project. The mechanical solutions Cannistraro implemented across both facilities are expected to reduce energy use by 48%, delivering cost savings of up to $2.5 million annually. Additionally, our client plans to potentially save $15 million in total maintenance costs with the new infrastructure upgrades.

Driving Project Timelines
Client
Cambridge Center. In 2012, Boston Properties recognized an opportunity to improve buildings 3, 4, and 5 of the Cambridge Center campus. They turned to Cannistraro to execute the complex HVAC upgrades as part of their six-month capital improvement project with the goal of keeping the buildings fully occupied during the project.
Our Tasks
Tasked with keeping existing tenants comfortable during the project, Cannistraro engineered temporary heating and cooling systems for each building while we replaced the boiler and chiller units. The original six-month planning period was restricted to two months due to on-site circumstances, and our project managers sped up timelines to remain on track with project milestones.
Skills Involved
- Preconstruction Planning
- Project Management
- Temporary HVAC
- Zero Lost-Time Injuries
- Fast-Track Project Scheduling
- Energy Efficiency
- Boiler Installation
- Chiller Unit Installation
Project Results
By 2013, Cannistraro completely replaced the heating and cooling infrastructure in all three buildings. We brought the upgraded systems online without any hassle or system downtime. Our experts simultaneously brought all HVAC systems up to code while maximizing energy efficiency. Even on a tight schedule, we were able to deliver on-time results with our team’s ability to adapt and look ahead, thereby saving our client the cost of project setbacks.
