In last November’s Back2Basics, I created a test for the readers based on the idea that the patient room design was similar to a pharmaceutical cleanroom, with an air lock for people to enter and leave the room.
The public’s taste for regional and local beer has flourished in recent years, but crafting a proper steam boiler system for its production can be sobering task. Pull up a bar stool and contemplate at least 23 design and maintenance facets to ensure that what’s brewing is all beer and no trouble.
It’s not necessarily a plug-and-play situation, but these chillers can play key roles and deliver meaningful savings in several scenarios. Waste heat, CCHP, standalone, and even renewable solar as part of the refrigeration cycle can all provide the setting for absorption success.
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.
This month, I want to address an issue which is as old as building systems commissioning itself. It was one of the first challenges commissioning professionals endeavored to resolve in order to more effectively and efficiently facilitate the commissioning process … and yet it still lingers.
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.
School, warehouse, office building … the boiler stories they tell put the focus back on specific circumstances and smart pre-design study to ensure their systems (and budgets) enjoy the best of times for as long as possible.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
