Best Ventilation Bang For The Buck In My Climate
I am in the process of a planning a new house. Approximately 2,000 – 2,500 square feet. ICF construction with sealed attic (spray foam under roof deck). I expect the house to be tight and want to make sure I provide for proper ventilation. I’ve read about the various options and I am now trying to determine what would be the best bang for the buck in my climate. The house will be built in the Lubbock Texas area (360 miles west and slightly north of Dallas). Climate is fairly dry. Not as dry as Arizona, New Mexico or the El Paso region of Texas but much drier than the eastern half of the state. We’re practically a desert compared to Houston.
Lubbock Climate Data:
Annual HDD = 3431
Annual CDD = 1689
Annual Days w/max temp over 90 = 80
Annual Days w/min temp below 32 = 93
Average annual rain = 18.6″
Average annual snow = 9.9″
Average wind speed = 12.4 mph
I plan to install some type of energy efficient fireplace with a source of outside air for combustion. I have not yet decided on whether or not to vent the range hood outside.
So, what do you think? Exhaust ventilation, supply ventilation, HRV, ERV, or something else?
Also, if anyone knows of a good builder with ICF experience in the Lubbock area, please let me know.
