This month, a consultant and NFPA committee chairman looks at the major items involved in a hospital’s life safety design. Like the fire risks themselves, the assorted relevant codes are evolving with regard to specifics like smoke dampers. HVAC wall penetrations, alarm zoning, and response plans are just three other aspects to consider in this demanding design environment.
In which CFD modeling lets us compare two possible design configurations for ventilation in a hospital patient room, yielding some similarities and perhaps surprising differences in what each configuration means for pathogen control and occupant comfort.
We’ve made some progress, but the fight against hospital-acquired infection (HAI) remains long and uphill. Here, we look at various risks and strategies, putting some thoughts on a wise approach to humidification in the context of the HAI battle.
When a community-based hospital adds a neonatal intensive care unit (NICU) so its most fragile patients can be cared for in-house rather than at a regional center 50 miles away, a family places enormous trust in the hospital’s ability to meet its baby’s health care needs.
Pressure independent control valves proved to be a key in wringing the benefits out of smartly managed chilled water temperature, but that wasn’t all. Airside energy recovery, desiccant dehumidification to eliminate reheat in operating room environments, and upgrading to ECM fan systems have all contributed to this hospital’s fiscal wellness.
For a building program to be successful and sustainable, it must include an operating budget as well as a construction budget. Fifteen to 20% of the total cost of a building is first cost, and that remaining 80% or more is in the operation of the building over its life.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop. Learn more about Grounded In Reality in the December issue. Other topics in the December issue include health care HVAC, Boilders, check out the Back2Basics, and more.
