Welcome to BTF Net Zero Designs

Putting your mind at ease: 

In our background we’ve seen firsthand the flawed stock plans sold online. 

We’ve seen furniture drawn half its size to make rooms ‘look big’

We’ve seen plans where the roof lines are not construct-able

And plans where the stairways between floors, simply don’t line up. 

You won’t have that from us. 

We’ve gone above and beyond to develop our plans to be contractor friendly and up to par! 

Our plans meet more than just the IRC. 

We’ve designed our plans to meet all of these:

At BTF we work to meet the newest available versions of the following codes & standards (plus a few more not yet listed!): 

• International Energy Conservation Codes (IECC)
• International Residential Code (IRC)
• American Society of Heating Refrigeration and Air Conditioning  Engineers Standard on Ventilation and Acceptable Indoor Air Quality in  Low-Rise Residential Buildings (ASHRAE 62.2)
• U.S. Environmental Protection Agency Indoor (EPA) AirPLUS
• U.S. Department of Energy (DOE) - National Renewable Energy Laboratory (NREL) House Simulation Protocols 
• National Program Requirements of Energy Star Certified Homes
• U.S. Department of Energy (DOE) - Zero Energy Ready Home National Requirements
• U.S. Environmental Protection Agency (EPA) Solar Photovoltaic Specification, Checklist & Guide
• California Energy Commission Building Energy Standards - Title 24
• Vermont Residential Building Energy Standard (RBES)
• PGH 2.0 Pretty Good House Design Guidelines 

The newest versions of these codes, standards & requirements, exceed  many local & sate codes currently in place. 

However - we recommend  you refer to your local building authority.  

Note: Our Net Zero plans are designed for cold climates. 

None  of our Net Zero or HVAC plans are designed for construction in the  following states:  Alabama, Arkansas, District of Columbia, Delaware,  Florida , Georgia, Hawaii, Kentucky, Louisiana, Mississippi, Oklahoma,  South Carolina, Tennessee, Texas, or Virginia.
