These sensitive applications call for looking at several established humidification techniques through a particular lens. The authors not only review the processes involved in various technologies but also some relevant secondary effects, such as a change (or no change) in the air temperature, that could be especially meaningful in a data center.
Generally, when we think about BAS, it is in the context of large commercial buildings, those well over 25,000 sq ft. According to the latest government data though (from the 2012 Commercial Building Energy Consumption Survey), 88% of all commercial buildings are 25,000 sq ft or less.
The sport of curling is a strategic game like chess, with an element of skill and experience. Played on ice in an indoor controlled environment, temperature and humidity are critical to setting ice speed and the amount of “curl” the stone will incur.
Will my smoke control system work properly during a fire? That is the question all building owners/operators should ask themselves. Smoke control systems are unique in that they often sit dormant (sometimes for years) and problems that can affect their operation may not be identified until it is too late. To ensure the right answer when you need it, catch up on device monitoring, commissioning, and why the self-test concept has received a bad rap.
The assortment of standards, variety of technologies, and evolving weather patterns don’t make it simple. However, humidification and dehumidification strategies that suit the facility’s location and address some spaces’ specialized demands are worth the effort.
The codes and standards aren’t what they used to be when it comes to ventilation requirements. It might also be time to reconsider real-life occupancies with regard to design demands. Is there room to tighten up and boost efficiencies while maintaining adequate airflows?
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.
