A growing number of building owners are looking to design buildings that produce as much energy as they consume each year. These so-called zero-net-energy (ZNE) buildings may sound like a pipe dream, but they’ve already become a reality in many parts of the U.S. and around the world.
Energy Management System Expected to Significantly Reduce Energy Costs
July 21, 2014
For the West Houston Community Center, the hot Texas summer means higher energy costs for air conditioning and an increased strain on its budget. But this summer will be much different thanks to lower energy rates from Houston-based Entelrgy and an energy management system donated by EnTouch Controls.
Savvy contractors working in this niche market focus not only on deep energy reductions, but on non-energy benefits, such as improved comfort, better IAQ, increased home values, and a more durable home.
This analysis shows how a water-cooled 500-ton chiller system when compared to a 500-ton air-cooled chiller system results in approximately $45,000 in annual operating costs savings. Additionally, the water-cooled system reduces peak energy demand by 45 percent.
A new company called Noesis announced that it is providing a collection of free tools, collectively called Noesis Free, that let the user analyze a building’s historical energy consumption and costs, compare buildings within a portfolio to find the best and worst performers (i.e., the opportunities for savings), and more.
The California Public Utilities Commission (CPUC) reported that its energy efficiency programs resulted in savings of 5,900 gigawatt-hours of electricity in 2010-2011, enough to power more than 600,000 households for a year — the equivalent of two major power plants.
Florida A&M University (FAMU) has chosen Siemens to implement a $12.2 million performance contract that is expected to save the university approximately $1.2 million in equivalent guaranteed annual energy savings.
A new generation of copper brazed heat exchangers feature design improvements that provide higher thermal efficiency performance, resulting in energy and cost savings. Models CB30, CB60, CB110, and CB112 cover a wide range of duties and will replace the CB27, CB52, CB76/77, and AC120 models.
Siemens Building Technologies Division announced that Michaels Stores Inc., the major arts and crafts retailer, has rolled out a series of Siemens advanced extensions to the Site Controls™ Energy Management System (EMS).
