A new federal courthouse on Long Island seeks not only to illuminate visitors with the light of the law, but with plenty of natural light as well. After appropriate deliberation by the designers, the final system does justice to some creative architecture, a challenging atrium, and even preplanned expansion strategies. By John Lennon, P.E.
Mixed-flow impeller roof exhaust technology usually has been deployed for re-entrainment prevention and odor control. Now, it's providing energy savings in industrial and educational settings in a heat recovery role. By Paul A. Tetley
It's a building designed to house the backbone of the Internet, that's what. As you might imagine, its special purpose informs every building system, from mechanical to fire detection and beyond. By Victor A. Neuman, P.E.
The building envelope and mechanical system can interact to either master potential humidity problems or encourage them. However, an integrated commissioning approach can pre-empt many pitfalls before they propagate. By John F. McCarthy, Sc.D., C.I.H.
A few safety initiatives regarding other water and piping issues have left thermal expansion as a potentially disastrous problem that designers must still address. Learn about the first signs of trouble, and take a look at the potential of thermal expansion tanks. By Jim Fuller and
When an Ontario medical center shifted to a new humidification system, it helped protect the health of patients, especially those most vulnerable to complications. Subsequent reductions in energy usage and related infrastructure improvements have made the retrofit all the more welcome. By Drew Robb
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.
