LEED v3: ICFs and Materials & Resources
August 13th, 2009 | Lets Get Technical!
Materials and Resources (MR): This LEED topic covers recycling building materials, and reducing construction waste and using regional materials within a 500 mile radius.
| Credit | Title | NC | Schools | CS |
|---|---|---|---|---|
| MR Credit 2 | Construction Waste Management | 1-2 | 1-2 | 1-2 |
| MR Credit 4 | Recycled Content | 1-2 | 1-2 | 1-2 |
| MR Credit 5 | Regional Materials | 1-2 | 1-2 | 1-2 |
Under the credit Construction Waste Management, Reward’s ICF product is designed so that the form reduces waste during construction. The amount of waste that is produced is often possible to recycle as the expanded polystyrene foam and the plastic ties along with the concrete and rebar are recyclable materials. Any waste that is generated is 100% recyclable. See website below for a list of all EPS recycling facilities for every state.

Reward’s insulating concrete form products contain recycled content and can contribute to the Recycled Content credit. The Reward plastic tie inserts are manufactured from 100% pre-consumer recycled first generation polypropylene plastic. One half (50%) of the calculated pre-consumer amount is included in the total value of recycled content for a project. The calculations and amount of recycled content that the iForm contributes is shown below.
For example, the 11” iForm tie weight is 188 grams
- 100%, (188 grams) is pre-consumer recycled content
- 1.5 ties per square foot
- 282 grams per square foot recycled content
- Foam Weight: 288 grams/square foot
- Total System: 570 grams/square foot
- Cost of System: $3.18/square foot
- Value of Recycled Content per Square Foot (282/570)($3.18)(50%) = 0.79
- % of product value recycled content $0.79/$3.18
Recycled Content of Reward Forms
| Form | Tie weight/sq ft | Foam weight/sq ft | Total Form weight/sq ft | Cost/sq ft | Value of recycled content/sq ft | % of product value recycled content |
|---|---|---|---|---|---|---|
| 9″ iForm | 272g | 287.6g | 560g | $3.12 | $0.76 | 24% |
| 11″ iForm | 282g | 287.6g | 570g | $3.18 | $0.79 | 25% |
| 13″ iForm | 292g | 287.6g | 580g | $3.25 | $0.82 | 25% |
| 15″ iForm | 303g | 287.6g | 591g | $3.44 | $0.88 | 26% |
| 17″ iForm | 348g | 287.6g | 636g | $3.60 | $0.98 | 27% |
The Reward ICF walls can also contribute under the Regional Materials credit. The wall consists of formwork made from expanded polystyrene foam and plastic ties filled with concrete. Reward’s formwork products are manufactured in several plants around the country. Most areas will be within a 500 mile radius. Concrete consists of cement, water, fine and course aggregates and air. The water, air and aggregates are derived locally. The total value of materials that have been extracted and manufactured within a 500 mile radius has to equal 10% for one point and 20% for 2 points.
Reward will qualify as a regional material for projects located within a 500 mile radius of each of Rewards six manufacturing locations - Post Falls, ID; Colorado Springs, CO; Nixa, MO; Becker, MN; New Brighton, PA; Orlando, FL. Depending upon the location of the project relative to the manufacturing plant, projects located in the following states covered by the circles below should qualify.
