Streamlining Surgery: Temperature & IAQ Versatility In The OR

An advance investigation into the needs and preferences of the medical team proved in valuable for a Virginia hospital retrofit. The range of desired OR conditions was demanding, but for good reason. The designers, armed with this info, applied experience and mechanical muscle to provide the environmental flexibility to operate from one patient to the next.

Successful Smoke Control

Successful Smoke Control: Caution & Coordination

This second look at the Museum Of The Bible project focuses on the integrated life safety design approach. The team arrived at a final design that not only provides functionality appropriately tailored to the space but also incorporates itself into architectural elements to preserve aesthetic value. The BAS plays a key role between the mechanical and electrical sides of smoke control as well.

The Museum of the Bible’s project team was already up against the extremes of Washington weather and the high demands of IAQ for artifact preservation. A system that harnessed adequate cooling, heating, humidification, and ventilation capabilities would still have one more hurdle: a physical footprint of hardly Biblical proportion. Get a first look at this testament to design acumen and true collaboration.
