The purpose of the building envelope is to keep external elements out of the building, that’s the easy part. Creating a breathable, insulated, air tight enclosure is the difficult part. In an industry offering a wealth of building materials and processes all designated for the building envelope it is impossible to apply a one case fits all combination of materials for any exterior wall. Choosing an assembly of materials ...more »
Building Envelope Call for Innovation
Novel Building Envelope Design for Increased Thermal Performance
In 2014, more than 40% of US primary energy and 70% of electricity was consumed in residential and commercial buildings, resulting in annual energy costs of more than $430 billion. The envelope of the building, which refers to the external walls, windows, roof, and floor of a building, is the thermal barrier between the indoor and outdoor environment and one of the primary determinants of energy use to maintain indoor comfort. In fact, approximately 35% of this consumption, equating to almost 15% of overall primary energy usage, is used to maintain a comfortable indoor environment, and thus directly related to the performance of the building envelope.
The building industry strives to produce cost-effective and eco-friendly technologies that improve the performance of building envelopes, while also considering the overall building health. It is crucial that innovative techniques and materials be developed that: reduce the amount of energy lost through the building envelope, contribute to improved occupant comfort, and have low product and installation costs. Such energy, comfort and cost considerations will best enable contractors and builders to provide customers with high-performing, sustainable buildings.
The challenge is to develop a new material or an installation method that uses readily available products to improve the thermal performance and air tightness of a wall assembly, without compromising the durability of the wall assembly. Innovative ideas on the designs of a wall assembly or the materials are welcomed. Examples of innovative materials include but are not limited to: phase change materials, vapor open materials, and integrating materials into wood sheathing / studs to increase their R-value. Examples of innovative wall assemblies could potentially provide thinner profile with higher R-value components, easier insulation installation methods with lower thermal bridging effects, among others.
The solution should comply with the following design criteria:
- Focuses on new construction for residential applications;
- Minimum U-Value (inverse of R-Value) equivalent to the residential requirements of IECC 2015;
- Materials and/or methods should reduce the likelihood of improper installation and thermal bridging impact;
- Cost effective materials and designs meeting a simple payback calculation of under 10 years; and
- Materials should be non-toxic and eco-friendly.
This JUMP Call for Innovation requires only a written proposal. Review and consideration of ideas does not require submitters to provide ideas with documented Intellectual Property (IP). If you are concerned about protecting the potential of your IP, Select the "On" option under "Only Allow Moderators and Admins to see my idea" on the "Submit Your Idea "page. This will not permit the JUMP community to comment, discuss, or vote on your idea.
Cash award of $5,000; will be sponsored by an Industry Leader in the Envelope Space for the top selected technology submission. The idea submitter will also be invited to discuss future collaboration with the Industry Partner and ORNL technical experts.
Depending on the needs identified ORNL may provide in-kind technical support of $10,000 - $20,000 to enable ORNL staff to provide prototype development, testing, 3rd party validation, or other defined needs.
Additionally, Successful JUMP participants looking for funding and incubation support may be invited to participate in the Clean Tech Open Accelerator Program based on technical and market merit.

This proposal describes the Whole Wall and Window Building System (WWW), an integrated building system for residential and commercial construction which meets and exceeds the requirements set out by the Oak Ridge National Laboratory (ORNL) in this Building Envelope Innovation Challenge. Some elements of this system have been used in construction before, but they have never been used together to achieve extreme energy ...more »
Use Dynamic Insulated Vinyl Solar Siding to recover heated air from the solar heated siding for a variety of direct and indirect uses within the building to displace a portion of purchased fossil and electric heating uses.
Conventional residential wall systems, such as stick framing, have four primary problems: 1) They are too costly for affordable housing due to piecemeal, time-consuming construction and high labor costs; 2) They are full of thermal bridges and fall significantly short in terms of energy efficiency; 3) With fragile materials such as polyethylene vapor retarders and relatively exposed sheathing, they are prone to moisture ...more »
Insulated Concrete Forms (ICFs) create the best living environments because you can quickly build durable, resilient, super insulated, airtight, comfortable & sound-absorbing building shells. ICFs for walls & for floors/roofs form cast-in-place, reinforced-concrete buildings and stay in place to provide superior insulation, space to run utilities, and backing for finishes. Combining many construction steps (framing, sheathing, ...more »
Panels made using an inner and outer sheet of fiberglass internally braced but separated in a way similar to Insulated glass windows. heating and air duct chambers would be molded in a way that all duct work and wiring routes between the to panels. Standard 4 foot by 8 foot measurement. Panels interlock sealed with a strip of rubber or caulk. Mold variation would allow for faux grain, log cabin, many styles for the exterior ...more »

Make SIP panels with “mushroom” insulation. Mushrooms Insulation currently in development by companies like Ecovative (https://ecovativedesign.com/myco-foam) could be used to make a non-toxic, fire resistive SIP system. SIPs provide R-3.5/ inch of insulation and grow to fill out a mold. A thin aluminum shell could be used for the exterior skin and mushroom mold. SIPs significantly reduce labor, minimize construction waste, ...more »
Like several JUMP contributors, I am frustrated by the lack of “out of the box” thinking, and “we can’t do that” attitudes that are keeping residential construction in the dark ages. Stick building a wall, one stud, one nail and one cut at a time, really? Still? I won’t complete the “if we can go to the moon….” cliché, but why aren’t we trying to harness the newest materials, machines and “makers” initiative to invent ...more »
MICF stands for Masonry ICF or Masonry Insulating Concrete Form. It is a stay-in-place ICF form system where the shells of the form are CMU instead of Rigid Insulation. Rigid Insulation is layered against the inside face of the exterior or both CMU shells. The shells are assembled in place with dovetail shaped plastic tees that also accept 1/2" pvc crossties. The key to using CMU shells as concrete form walls in a labor ...more »
