While modeling software is often used for the initial design of high-performance buildings, the on-going benchmarking, commissioning, and monitoring of these structures is usually the purview of a building automation systems (BAS).

HVAC systems in commercial buildings consume a lot of energy, which is why many building owners and managers are looking at replacing their older, inefficient equipment with new high-performing systems.

As an HVACR contractor and national chairman of ACCA, I can tell you that, when it comes to my industry, public policy has fundamentally ignored a key energy-efficiency issue for some time.

Challenged to do more with less, data centers are seeking innovative ways to keep operating costs as low as possible — all while computer technologies may be changing as often as every three months. In a market demanding denser and more powerful electronics, data centers are pressed for cooling technology that can keep up with the times.

Originally built in 1872, The Foundry has a rich history dating back more than a century. Once the former manufacturing campus of industrial powerhouse Brown & Sharpe, the 13 brick buildings located on 26 acres at the edge of downtown Providence, Rhode Island, have been meticulously restored into a mixed-use complex, which bridges the old and new.

 

ESP-Systemwize is the evolution of Bell & Gossett’s ESP-Plus Online. It integrates the most popular aspects of the previous program while adding new user-friendly features to specify efficient pump systems.

The eco-LSWE closed-circuit coolers feature an ellipti-fin coil and CrossCool™ internally enhanced tubes to increase the heat transfer of the coil, which improves the unit’s cooling capacity.

Energy efficiency ratings (SEER/EER) of air conditioners and heat pumps keep rising, thanks to new technologies such as electronically commutated motors (ECMs), inverter-driven compressors, and advanced heat exchangers. These technologies have helped boost high-end cooling equipment ratings to the mid-20-SEER range, which was unthinkable just a few years ago.
