What Do You Think of Most Efficient?
The R-5 window may be back as the Environmental Protection Agency has released its draft criteria for Most Efficient designation for windows under the Energy Star windows, doors and skylights program. In addition to other requirements, including NAFS certification, the newest high-performance criteria sets a minimum U-factor of 0.20 for all regions of the country.
Many in the industry have supported the idea of a Most Efficient program for windows, as EPA has created in a number of other Energy Star product categories. The Most Efficient designation provides a way to differentiate ultra-energy-efficient products, while lessening pressure to ratchet down the regular Energy Star criteria too much.
So will you offer Most Efficient products? That's our poll question of the week. And, of course, I'd like to hear from you. Is Most Efficient a plus for the industry? Will it promote demand triple-glazing and other high-performance options? Will it benefit homeowners? Post a comment and let me know what you think.
Survey Results as of 10/24/2012:
Will probably not sell "Most Efficient" windows
Will take a wait-and-see approach to "Most Efficient" windows
Plans to offer "Most Efficient" windows as soon as possible
Will probably offer "Most Efficient" windows soon
Doesn't sell windows, so it does not apply to us.
Our poll results suggest some window and door companies will be moving forward with "Most Efficient," but it's not for everyone. That seems to be what EPA is looking for.
As comments indicate, some manufacturers are already at the performance levels necessary with some of their products. It will be interesting to see, looking forward, if those manufacturers not offering products with those types of performance numbers will feel compelled to get there.
