ASHRAE 170 is just the baseline for the fight against hospital acquired infections (HAIs). The ongoing human and financial tolls taken by these infections point to the need for engineers and facilities to raise their IAQ game wherever possible. Move beyond the minimum and get into the what, where, and how of HEPA filtration, ultraviolet technology, and catalytic air cleaners.
Cornell’s Bill and Melinda Gates Hall required a suitably thoughtful design process. After considerable analysis, an unusual strategy emerged, led by chilled beams and DOAS with key dehumidification elements.
Do you remember your first college Parents Weekend, when as a freshman you welcomed mom and dad into your room? Did you have to hastily transform your room into an “acceptable” living space just prior to this reunion?
Few areas can be as tough to condition as pools and ice rinks. Indoor pools, or natatoriums, need to be able to maintain a space temperature warmer than the water temperature and space humidity between 50% to 60%.
Critical facility HVAC and indoor air management is not all alike! In doing my homework for writing this column on critical facilities, I have been struck by the precision of IAQ monitoring in data centers.
