The U.S. Department of Energy (DOE) and the U.S. Department of Education have joined with the National Science Teachers Association to launch America’s Home Energy Education Challenge, a new energy education initiative. The goal is to motivate students across the country to learn about energy efficiency and help their families save money.
The “Implementation of National Consensus Appliance Agreements Act of 2011” (S. 398) bill, recently introduced in the U.S. Senate, would enact into law several consensus agreements that would set new federal efficiency standards for residential furnaces in two regions, for central air conditioners in three regions, and for central heat pumps in one, national region.
CityCenter, an $8.5 billion resort development on the Las Vegas Strip, may be billed as the largest and most elaborate commercial construction project in U.S. history, but the mechanical systems that manage the indoor environment were chosen based on consistency and simplicity.
New Frontiers Natural Marketplace decided to test the claims of refrigeration equipment manufacturer Muller Industries by having three of its 3C hybrid condensers installed at the store in San Luis Obispo, Calif.
In a survey of more than 1,500 homeowners conducted by Emerson Climate Technologies Inc. late last year, a high percentage of consumers showed continued interest in potential energy savings as a major purchase criterion when replacing an existing HVAC system.
Tall ceilings can be both a builder’s dream and an HVAC contractor’s nightmare. The introduction of air movement by means of large-diameter, low-speed fans can provide the necessary comfort, further optimize HVAC system effectiveness, and save money on both energy use and building supplies.
On Jan. 28, the Building Performance Institute (BPI) released a proposed new standard (BSR/BPI 101-201x, Home Energy Auditing Standard) for public comment. The Air Conditioning Contractors of America (ACCA) reviewed BPI’s proposed standard and believes that a number of significant flaws need to be addressed and a number of passages need to be improved.
The need for energy efficiency and the desire for
intelligent energy efficiency have created a hunger for data. This trend
started 10 years ago (or more) in the building controls industry and is now
being seen in the refrigeration controls sector.
Highlighting the importance of finding balance in design, this year’s American Society of Heating, Refrigerating and Air-Conditioning Engineers’ (ASHRAE) Winter Conference will focus on zero-energy design and greening the industry. The program will include paper-related sessions, application-oriented, non-paper seminars, and open discussion forums.
Thermography uses an infrared camera (thermal imager) to capture two-dimensional representations of the surface temperatures of parts of buildings. Often, those images reveal temperatures or temperature differences that indicate conditions contributing to the waste of heated or cooled air and, as a result, needlessly excessive energy costs.
