The Human Services Building was new construction to house various social service organizations within the county. The three-story office building with atrium utilized an 80-ton variable air volume (VAV) direct expansion (DX) air-handling unit. High efficiency modular boilers were installed for hot water reheat coils. In addition to mechanical systems, lighting, plumbing, fire protection, electrical and fire detection systems were designed. The controls are direct digital controls (DDC) and communicate back to the engineer’s office in Boulder for monitoring and adjustment.
