Project Background
Adventist Healthcare (AHC) is near completion on an innovative energy efficiency project at its 443-bed Shady Grove Medical Center, a nationally recognized acute care facility located in Rockville, MD. The project is expected to significantly lower greenhouse gas emissions and represents a critical investment in the patients and communities AHC serves across the Metro DC region.
The 2.2 MW combined heat and power (CHP) project, which launched construction in September 2021 and is slated for completion in the first quarter of 2023, will result in an annual savings of $1 million, and is eligible for nearly $3 million in incentives, to be reinvested back into the community.
Implemented in partnership with Edison Energy, the project utilizes 1.1 MW cogeneration engines, a heat recovery steam generator, and an absorption chiller, resulting in an energy supply that is less dependent on fluctuations in utility pricing and increased flexibility in energy sourcing (pictured below!).
The project builds on Adventist’s broader Shady Grove expansion and renovation, which includes a new 150,352-square-foot patient care tower that will allow for larger, state-of-the-art replacements for its Intensive Care Unit and Emergency Department. The six-floor tower will stand as a symbol of Adventist’s commitment to the well-being of the community.
Project Updates
Our first milestone was installing condenser water and chilled water pumps to circulate water through the new cooling tower and chillers. The team will turn over the chiller system to the owner within the next few weeks.
The team has completed the façade of the new addition and is now working on getting conditioned air to the space so that they can start installing some of their major electrical components. The project team also completed running the underground electrical conduits that will ultimately connect the power plant’s new electrical room to the hospital’s electrical grid.
The team installed a new boiler, which they set, piped, and completely tied into the hospital’s system. Because the team is working on an active hospital campus that must continuously produce energy and steam, the team devised a plan for coordinated outages in order to bring on and off both new and used boilers. This will ensure that there are two boilers always in service. Now that the team has installed the first boiler, they will start work on the second boiler.
