Net-Zero Energy

Building with Energy in Mind

Energy-savings and environmental sustainability are key priorities for architects, engineers, and owners during both restoration and new construction projects.

Using insulated concrete forms (ICFs) for structural walls, the building will have continuous exterior insulation from the basement to the attic, virtually eliminating the thermal bridging that contributes to energy loss.

The superior R-value and seamless connectivity of Nudura’s ICF blocks create an energy-efficient building envelope, decreasing a structure’s carbon footprint and reducing heating and cooling costs throughout its life. Nudura ICFs also contribute to LEED Programs, the Passive House Standard and the Living Building Challenge.

In combination with other sustainable building materials and renewable energy sources, Nudura ICFs aid net-zero, also known as zero-energy, and net-positive initiatives, where buildings produce as much, if not more, energy than they consume over the course of a year. For more information on implementing net-zero, view ASHRAE’s Advanced Energy Design Guide- Achieving Zero Energy series for multifamily, K-12, and small to medium office buildings.

Any structure type can utilize ICFs and benefit from these energy-savings, from an apartment building, healthcare facility, or company headquarters. Schools and other educational buildings, in particular, frequently seek out net-zero goals due to their high HVAC and operational costs when built using traditional wood-frame, steel-frame, or CMU construction. The money saved from using ICFs and other sustainable practices can be reallocated to directly serve the students or community at large.


“Every dollar we save in energy usage is a dollar we put back into education.”

Garry Chaffin, Vice-Chair of Warren County Schools 


How Nudura ICFs Contribute to Energy Savings

Nudura’s ICF blocks offer an R-Value of 24 with thermal mass properties of up to R-50. This insulation values is superior to traditional wood framing and helps to stabilize the internal temperature from day to night temperature fluctuations.

What does this sustainability actually look like when utilizing the full range of Nudura’s ICF products?

Structure Solutions

Insulated Concrete Forms (ICFs) are stay-in-place forms that offer you a variety of superior benefits when building your next project. Nudura ICFs are stacked, then steel reinforced and filled with concrete which completes the building envelope in one building step. With a full range of products to meet every insulation need, using Nudura will provide you with the an air tight, fully insulated building envelope with added benefits over traditional construction.

1. Nudura Standard Form

Nudura Standard Forms are 8' (96") in length, the largest standard block in the industry. Nudura's forms consist of two stay-in-place panels of Expanded Polystyrene (EPS) connected with our patented innovative hinged folding web.

2. Nudura 90° Form

The 90° form is fully reversible, eliminating the need for different right and left corners. Nudura also offers a 45° form, a radius, a taper top and all of the accessories needed to ensure the envelope of any structure can be built with Nudura.

3. Nudura Optimizer

With the Optimizer form it is easy to optimize the height of any wall. Designed to be used as a height adjuster at the top of the wall, the Optimizer allows the installer the ability to hit 17 different stack heights from 4’ (1220 mm) to 12’ (3600 mm).

4. Nudura One Series

The One Series is ideal for elevator shafts, stairwells and other areas that require non-combustible material.
