Housing starts declined 4.3 percent to a seasonally adjusted annual rate of 529,000 units in the final month of 2010, according to figures released by the U.S. Department of Commerce. However, the year-end data indicate that production of new homes improved 6.1 percent in 2010 over 2009.

There have been two approaches to capturing the sun’s energy: photovoltaics, to turn sunlight into electricity, or solar thermal systems, to concentrate the sun’s heat to boil water to turn a turbine, or use it directly for hot water or heating. But there’s another approach that was sidelined because nobody found a way to harness it in a practical, economical way.
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.
This troubleshooting situation is a look ahead to the upcoming cooling season. Our customer has called to say that their heat pump “isn’t cooling at all,” and while the outdoor temperature is only in the mid 80’s, it’s quite uncomfortable in the house.

Desiccant dehumidification is a cost-effective and energy efficient option to reduce a supermarkets’ moisture load to lower energy costs, ensure food safety and customer comfort, and provide the proper amount of fresh outdoor air at the precise temperature and humidity necessary for the space.
Workplace violence risks are real, and employers face legal liabilities when employees or customers are victims. Employers must understand how they could be vulnerable to a lawsuit after an incident of workplace violence, and what they can do to prevent such incidences.
Housing starts rose 3.9 percent in November to a seasonally adjusted annual rate of 555,000 units from an upwardly revised number in the previous month, according to the U.S. Department of Commerce. This marked the first upward movement in new home production since August, and was entirely attributable to a nearly 7 percent gain in single-family home building.
Effective pump maintenance allows industrial plants and commercial facilities to keep pumps operating well, to detect problems in time to schedule repairs, and to avoid early pump failures. Regular maintenance also reveals deteriorations in efficiency and capacity, which can occur long before a pump fails.
