Energy, efficiency, and economics were the key topics at the 13th Danfoss EnVisioneering Symposium held in Washington, D.C., recently at the Russell Senate Office Building. It was appropriate that Senator Jeff Bingaman (D-N.M.) keynoted the event as he is the Chairman of the Energy and Natural Resources Committee.
A group of nearly 550 individuals packed the South Point Hotel in Las Vegas for the 2011 HVAC Excellence National HVACR Educators and Trainers Conference (NHETC). The NHETC is an annual event dedicated to providing continuing education for HVACR educators and trainers.
It is one thing to install efficiently running refrigeration equipment. But it also has to be energy efficient - according to a wide range of standards. That’s why Emerson recently issued a white paper called Status of Energy Regulations for Commercial Refrigeration Equipment.
The theme of the 22nd annual North American Energy Efficiency Forum was “Energy Efficiency: The Smart Path to Energy Security and Economic Growth” and speakers addressed the importance of pursuing energy efficiency and alternative energy sources not only to reduce energy costs but also enhance national security.
Servidyne Inc. announced that it is has been awarded contracts to provide energy efficiency and demand response services for commercial and institutional buildings in the city of San Antonio. The contracts call for the company to provide retro-commissioning and energy audit services. Servidyne also will perform demand response audits.
More than 350 commercial controls contractors and distributors gathered to attend Honeywell’s Momentum Conference. The annual event serves as an energy, environmental, and economic idea exchange for those who provide the building industry with HVAC, security, video, and intrusion products and solutions.

You may be familiar with the Energy Star® label on energy efficient heating and cooling equipment, but did you know there are also Quality Installation (QI) guidelines to help ensure that heating and cooling equipment is installed properly? Nearly half of all heating and cooling equipment in U.S. homes never performs to the advertised capacity and efficiency due to installation problems.
The first step in evaluating a building’s energy use involves an energy audit. This consists of various home performance tests that identify opportunities to reduce energy use. More HVAC contractors are starting to offer this service because of its direct impact on a home’s heating-cooling costs.
As HVAC products get more and more efficient, the logical question is what level will they top off at? The laws of physics can limit the efficiency levels of air-source heating and cooling equipment. The laws of economics also come into play, as the cost for each incremental escalation in efficiency can substantially increase the cost of the equipment.
