A small team led by an award-winning Florida engineer decided to test conventional wisdom about pressure loss, both in a straight run and in comparing supply and exhaust scenarios. Early returns suggest the data may be flowing in an unexpected fashion.
With a wide spectrum of specialized spaces and particular outside air requirements, a hospital’s en-ergy-efficiency efforts start when arranging which areas go where. From there, the author leaves no technology unturned — chilled beams, geothermal, DOAS, VRF, etc. — in evaluating which ap-proaches might best contribute proper ventilation and humidity in which environments, with an eye on minimizing facility energy consumption.
Brush up on the environmental factors that can throw things out of, well, balance, and note how space pressure problems can create assorted complications.
A lot will happen under the single rooftop of the new Wesley Long Cancer Center in Greensboro, NC. The 33,000-sq-ft addition to the Moses Cone Regional Cancer Center includes a business office, lobby/waiting area, admitting, phlebotomy lab, breast cancer treatment, exam areas, chemotherapy, an auditorium, and education classrooms.
Leakage caused by modern cleaning techniques, evolving codes, increased airflow requirements ... kitchen ventilation design has become more complicated than the old sizing and design challenges. Of course, they’re still around, too. Grease is the word, so review these tips to keep it from popping up in the wrong places.
Critchfield Mechanical, Inc. an HVAC engineering firm in Menlo Park, CA needed a cost-effective and energy-efficient perimeter zone ventilation solution.
Just what the doctor ordered: specifics on pre-filters, after-filters, AHU tips, and more to meet
critical IAQ goals and prevent that ventilation system from operating in a “fog.”
Plenty of potential ventilation crises await many otherwise unassuming buildings, thanks to
nothing more sinister than truck accidents, emissions from nearby buildings, or unavoidable
natural disasters. However, by pairing a clear basis of design with HVAC response strategies,
building owners can apply some forethought and preparation to avoid worst-case consequences.
Start by asking the right questions about your facility.
Pharmaceutical giant GlaxoSmithKline faced some extreme dehumidification requirements for its facility manufacturing denture-cleaning tablets. The strategy it selected not only reached target humidity levels but also allowed a 3º increase in chilled water temperature. Get the details on the system and savings that put smiles on the faces of this project team.
