A bill in the Senate aims to update the efficiency standards of appliances and building systems, including furnaces, heat pumps, and central air conditioners. Titled the “Implementation of National Consensus Appliance Agreements Act of 2011,” it divides the nation into three regions with different efficiency standards for each. It also recommends more stringent building codes for new construction.
Whether you use tea leaves, tarot cards, a crystal ball or just good old fashioned statistical analysis, the future of the housing market remains murky and the overall economic recovery seems to be missing in action, but one thing is clear. Definite housing trends have emerged and they won’t be going away anytime soon.
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.
As a host of pressures - from demanding consumers to stringent regulations to rising energy costs - continue to bear down on the industry, compressor manufacturers are reiterating that energy efficiency is the best response to these issues.
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.
For some time, energy efficiency and IAQ were thought to be mutually exclusive HVAC goals. They actually can have negative or positive effects on each other that can be mitigated by contractors in a number of ways: coil care, duct repair, and the judicious use of specific equipment among them. A recent trend has been linking the impacts IAQ and efficiency can have on each other.

Three years ago, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) set out to achieve new efficiency goals for Standard 90.1. The association announced at its 2011 winter conference in January that it had been successful. It now attains site energy savings of 32.6 percent and energy cost savings of 30.1 percent without plug loads.
Many contractors are asking what happened to Home Star, the proposed legislation that would have extended rebates to homeowners who invested in energy efficiency upgrades for their homes. While the bill was a hot topic for much of 2010, it ultimately failed to pass in the Senate, and has not been reintroduced in Congress so far in 2011.
