The infrastructure and bones of historical buildings are extremely delicate. They require just the right environmental conditions to avoid causing damage, and during a renovation this is particularly difficult to achieve.

When Kirlin Mechanical was tasked with renovating the Cannon House Office Building, Washington DC’s oldest congressional building, they needed a way to keep relative humidity low and meet high power needs —  and all despite low electrical availability.

Our system succeeded in keeping relative humidity within the required range throughout the changing seasons, as well as maintaining the temperature and negative pressure required inside the building. The renovations could steam ahead without risk of damage to this important historical office.
