Electric Power Plants:US power grid mix includes coal, natural gas, fuel oil, nuclear energy, hydropower, biomass, wind, geothermal energy, etc. 3.2 KWh of “source” energy are needed for 1 KWh of electricity delivered to the “site”.

Natural Gas:Includes all activities required to extract, produce and deliver thermal energy to customers. 1.16 Btu of “source” energy are needed for 1 Btu of gas delivered to the “site”.

Polyiso Installation:

Raw Material Manufacture:Includes processing of raw materials for making chemicals such as diphenylmethane diisocyanate (MDI), polyester polyol, pentane blowing agent, and additives such as �ame retardants and catalysts/surfactants.

Recycled materials are used for manufacturing facer and some chemicals such as polyester polyol.

Poly iso : The Product for Bui ld ing Sustainabi l i ty

Raw Material Extraction and Re�ning:Involves extraction of crude oil and natural gas, mining of coal, cultivation of crops, re�ning of crude oil into benzene, pentane, diesel, propane, etc.

Polyiso Use:Rigorous Whole Building Energy Analysis based on the US DOE EnergyPlus simulation program was applied to estimate energysavings and GWP emissions prevented during the use phase. Integrated whole building simulation is essential for modeling realistic energy consumption. ASHRAE 90.1 Appendix G procedures were followed to provide credible data on energy consumption comparisons.

Energy savings from increasing insulation from R-15.3 to R-20.4 amount to 15 million MJ, with embodied energy being only 5%compared to the energy saved. Energy savings from increasing insulation from R-15.3 to R-30.6 total 31 million MJ, while theembodied energy for additional insulation is only 7% compared to the energy saved.

Global Warming Potential (GWP) emissions prevented in the use phase by increasing insulation from R-15.3 to R-20.4 are nearly1 million kg CO2-equivalent, while GWP emissions generated from all other life cycle phases are about 4% compared to GWPemissions prevented. GWP emissions prevented in the use phase by increasing insulation from R-15.3 to R-30.6 total 2.1 million kgCO2-equivalent, while the GWP emissions contributed from all other phases are only 6% compared to GWP emissions prevented.

End-of-life (EOL):Involves transportation to anddisposal of insulation in a localsolid waste land�ll.

Functional Unit: Polyiso insulation with a speci�ed minimum thermal resistancefor a one-story 125,000 ft 2 retail building roof over a 30-year insulation life.

Increased levels of polyisocyanurate (polyiso) insulation save energy and prevent Global WarmingPotential (GWP) emissions during polyiso use that far outweigh energy and GWP emissions associatedwith making, transporting, installing and managing polyiso at end-of-life.

Embodied Energy & GWP:

Based on current polyiso manufacturing and use for commercial roo�ng in North America, life cycle inventorymethods from ISO 14040 were used to estimate “cradle to end-of-life” energy and GWP emissions.

agents. The chemical mix reacts as it travels on a belt through an environmentally con-trolled tunnel, free-rising into continuous bunstock.

Polyiso buns are cut into sheets or blocks for building insulation applications where lami-nate may be applied, or fabricated into shapes for piping insulation. The product is then shipped to the end-user and installed.
