Stego Sustainability Report

GREEN BUILDING CONTRIBUTIONS

PHIUS (Passive House Institute US): a certification based on passive house prin ciples. Passive building focuses on aspects like continuous insulation, an airtight envelope, high-performance windows, and vapor control layers to create extremely durable and efficient buildings and homes. Foundation water vapor control is a re quired component of PHIUS Certification Guidebook v3.02. PHIUS certification also earns U.S. Department of Energy Zero Energy Ready Home (ZERH) status. Phius Certified Consultants have completed a comprehensive training course and passed a rigorous exam. • Stego products exceed minimum requirements for water vapor control be- neath slabs and as a component of required sealed crawl space. Stego accessories are engineered to help achieve a monolithic and fully sealed installation, critical to air sealing the building envelope. Stego also has a Phius Certified Passive House Consultant on staff (see pg 49 for more information). ENERGY STAR ® : a government-backed certification for energy efficient consumer products and buildings. ENERGY STAR certified homes achieve a higher level of performance compared to code built homes through third-party verified building science measures.* • Stego products can contribute to EPA’s ENERGY STAR certified homes and apartments, as Stego products exceed requirements for the capillary break beneath slabs and covering the ground in crawl spaces outlined in the mandatory Water Management System Builder Checklist Guide. Indoor airPLUS: from the U.S. EPA, this program builds on the EPA’s ENGERY STAR program for new homes but incorporates additional focus on advanced indoor air quality provisions. Indoor airPLUS homes not only exceed minimum energy efficiency requirements but are safer and healthier. • Stego products exceed minimum requirements for slab and crawl space water vapor protection as part of the Moisture Control section.

Standards, Certifications, and Rating Systems (continued)

NGBS (National Green Building Standard)/ICC 700: administered by Home Inno vation Research Labs, NGBS is a green building certification specifically designed for homes and multi-family residential. It was developed in partnership between ASHRAE, the International Code Council (ICC), and the National Association of Home Builders (NAHB). • NGBS 2020: Enhanced Durability and Reduced Maintenance Section 602.1 Moisture Management — Building Envelope: ° 602.1.1.1 — Stego products exceed the vapor retarder requirement for below concrete slabs (Mandatory). ° 602.1.4.1 — Stego products exceed the vapor retarder minimum over floors of unconditioned, vented crawl spaces (6 Points). ° 602.1.4.2 — Stego products exceed the vapor retarder requirement over floors of conditioned, sealed crawl spaces (Mandatory); and below a concrete slab in crawl space (8 Points). ° 602.1.5 Termite Barrier — Pango Wrap is Home Innovation NGBS Green Certified as a continuous physical foundation termite barrier (4 Points). • NGBS 2020: Pollutant Control Section 902.3 Radon Reduction Measures: ° 902.3.1.1 Soil-Gas Barriers and Base Course — Stego products exceed soil-gas retarder minimum as part of passive or active radon mitigation systems (Mandatory to 12 Points).
