Energy and Atmosphere: The high performance thermal envelope of ICF construction can offer a significant contribution toward achieving all possible nineteen (19) of the Energy & Atmosphere Optimize Energy Performance points.
The energy effectiveness of an ICF wall is due to the unique synergy of continuous insulation, virtually no air infiltration and the added thermal mass of the concrete wall.
Sustainable Sites: The Sustainable Sites Credit calls for reducing the development footprint and limiting site disturbance to conserve existing natural areas, specifically credits 5.1 & 5.2, “Site Development, Protect or Restore Habitat” and “Site Development, Maximize Open Space.” TransForm construction can reduce impact to a construction site, as the bracing can be erected on the inside of the TransForm wall, with limited construction activity around the perimeter.
ICFs contribute to the Materials & Resource Credits in three areas: construction waste reduction, recycled content and regional materials. Credit 2 seeks to reduce construction waste. ICF construction typically factors in only 2–5% waste, much lower than most other wall materials.
Both ThermoForm and TransForm have incorporated recycled content in the plastic rails it uses and the Recycled Content Credit 4 is applicable. Also, the concrete mix used for TF forms can incorporate high percentages of fly-ash, which is 100% pre-consumer waste. The reinforcing steel (rebar) is generally over 80% post-consumer recycled. LEED calculates recycled content by weight. The recycled fraction of the assembly is then multiplied by the cost of assembly to determine the recycled content value. The values of all the recycled materials used in the building are adjusted for pre- vs. post-consumer and then added together to determine a combined recycled materials percentage of total value.
Using TF Forms for the building envelope can reduce temperature and humidity variables, and facilitate the maintenance of the comfort ranges specified for Credit EQ7.1, Thermal Comfort.
Innovation and Design Process Credits This is provided for projects that have the opportunity to achieve exceptional performance above the requirements set by the LEED Program. This can be achieved in a combination of ways as specified by the LEED 2009 for New Construction and Major Renovations Rating System. In essence, three different paths are used to determine how a project can achieve all 5 points possible.
With any LEED project, if a LEED Accredited professional is involved in the process, one LEED point is awarded to the project.

In the heart of tornado alley, more and more home owners are choosing to build with Insulated Concrete Form homes for disaster resistance and energy efficiency. Hideaway Developments, Inc. has a brand new insulated concrete form home for sale in their newest pocket community development in Ozark, Missouri.
According to the article below by DWM Magazine, Net-Zero-Energy Homes saw strong growth in 2016. The article is geared toward the door and window manufacturing sector but realizes how important the building envelope is in achieving the Net-Zero-Energy Home. At TF Forming Systems, we know how critical the building envelope is. This is why we are passionate about our vertical insulated concrete forms.
