Yankee Green
AN AFFORDABLE HOUSE. COMPARED TO A CONVENTIONAL STICK-BUILT NEW HOME, IRC 2015 STANDARDS, A "YANKEE GREEN HIGH PERFORMANCE HOME" IS NOW TRENDING AT 2%-5% MORE BUT WITH SIGNIFICANT MONTHLY DOLLAR SAVINGS. OVERALL IT IS LESS EXPENSIVE.
"Yankee Green High Performance" maximizes the land, siting, resources, and money to create a sustainable home environment that is healthy, comfortable, airtight and durable, and energy-efficient. It is simply common sense, net energy or not, solar or not!
Whole system approach – All variables – house, energy, permaculture, neighborhood, terrain, sun
Envelope – framing, water flow, airflow, penetrations, wall/roof system, energy tested
Ultra-efficient – comparative to old school thinking; water vapor barrier, highly tight and insulated; blower tested
Manufactured Unity Homes – highly engineered – walls, complete panels, and modular. These words are not your father’s Buick. Highly advanced and no longer mean a double-wide
Just because a home is built "new" does not mean it really is new. Most builders in the Maine Mid-Coast area may tell you they build to the latest, most current building codes. They do because Maine only requires the older IRC 2009 as current.
Many builders are likely using 6-9 year old standards and are behind the technology. Much has changed since 2009. Maine is just now transitioning to 2015 IRC in the coming year (2021). However, Maine exempts the new code for testing, keeping the 2009 IRC 7 ACH50 “big hole” specification. 2009 IRC is 7 ACH50, a very big hole in the wall,. The 2015 IRC is smaller but still a significant hole with 3 ACH50. Our recent NEW house tested at 0.7 ACH50. One IRC standard hole is ~ 3ftsq; one is 1sqft, while our equivalent hole is the size of a dryer vent opening.
That is Passive Haus standards at 0.6 ACH50. The highest building standard.
One cannot take a traditional stick-built design and "super insulate it" and expect excellent results. The home must be properly designed from the beginning to be high performance along with the correctly matched energy and fresh air healthy systems.
Ask your builder to provide all his past blower test results. If he is not blower testing, or testing above 1 ACH50, we suggest you find another qualified builder.
Landicity®-Builders builds to the most current IRC 2018+ standards with continual upgrades and improvements. While many other builders may not blower test, we do blower test with outstanding results, at or below 1 ACH50. New 2018+ IRC standards are being adopted by many states and we incorporate them whenever feasible.
