In early 2020, buildings around the world transitioned from full occupancy to low occupancy in a matter of days.

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.

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.

One of the most important factors in the efficiency of any HVAC system is the selection and implementation of the proper control sequence of operations. 

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.
