This month’s Facility File is based on a new 40,000-square-foot office building HVAC system using VRF heat pump equipment with a focus on the Back2Basics February test. The project will include two VRF systems, each serving approximately 20,000 square feet of space. The building will also have a 100 percent DOAS gas-fired rooftop HVAC system for ventilation to the occupants in the building.
This month's Facility Files will focus on the Back2Basics test addressing the renovation of an existing Metro station with the addition of a new smoke evacuation system located within the building and within the subway’s inbound and outbound tunnels. The associated ADA-compliant elevator will have its own stand-alone, engineered, smoke control, 100 percent outside air fan to a positive-pressurized elevator shaft system.
This month’s Facility File will focus on the B2B December test for the energy retrofit of a commercial office building hot water heating system conversion from a utility company steam system to a new, high-efficiency condensing boiler system.
A BAS spec is typically a section within Division 23 (e.g., 230923), while the sequences and points are usually provided elsewhere (i.e., on the drawings, in section 230993, or some combination thereof).
HEMCO has introduced its Softwall Clean Rooms, designed to meet ISO 5 - ISO 8 requirements. The clean rooms feature a flexible design that allows them to locate over and around equipment, with the option of being mobile with casters. The structural framework is of aircraft anodized aluminum with clear vinyl curtains around the unit.
On Demand Ductwork and piping are only two components fighting for space in modern building design. That space is tight, avoidable changes can be expensive, and conflicts identified later can be even more costly in time and money.
