Underground cooling towers and controls with graphics custom-designed to complement the facility engineers’ operational expectations? These are just two aspects of the Moscone Center’s expansion strategy to stand out and stand up to unusual demands.
This design environment keeps moving, but the performance and cost pressures remain. Weigh air-side and water-side economizers carefully: not just one or the other, but the options within each approach.
Modern data centers are evaluated not just on reliability but also on the efficiency of the cooling plant that supports them, so the cost to cool data center space is a key issue that must be addressed during design and system selection.
Carrier has released its newly designed variable air volume (VAV) WeatherExpert™ 48/50LC 6- to 23-ton packaged rooftop units. The newly designed WeatherExpert VAV models, available from 23 tons down to 6 tons, use a dedicated i-Vu® controller that links communication between the system zone terminals and the unit to efficiently adjust the air flow and compressor stages that are required.
Look at not only some nearly automatic benefits-in-waiting for your average hospital boiler retrofit, but also at some ideas for what to do if there isn’t budget for a full replacement. Meanwhile, a short laundry list of hospital-specific boiler considerations actually includes the laundry (but not how you might expect).
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.
Sometimes it’s less important to think outside the box than to notice that the stuff inside the box has changed. In the case of airside economizers, more modern components and seasonal opportunities can make things work swimmingly.
Engineered Systems magazine’s February 2020 issue showcases the winners of our annual 20 to Watch: Women in HVAC contest, examines how a new MLS soccer facility partnered with a Woman Business Enterprise to design an energy-efficient VRF and DOAS system, continues our discussion on simple and complex sequences, and much more.
