Green Building Events – Scottsdale passes 2021 codes Comments Off on Green Building Events – Scottsdale passes 2021 codes

Scottsdale becomes the first in the state and one of only a few nationwide to adopt mandatory ‘green’ building code requirements

On Dec. 6, Scottsdale City Council adopted the 2021 edition of the International Energy Construction Code (IECC) and the International Green Construction Code (IgCC) as mandatory codes.

The new energy code (IECC) applies to new residential and commercial buildings and will result in lower energy use, cost savings, thermal comfort and reduced environmental impacts. Benefits include an energy cost savings of 10.6% and greenhouse gas emission reduction of 10.2% as compared to the 2018 IECC. It is estimated that energy codes for residential and commercial buildings will be able to save $138 billion energy cost savings and 900 million metric tons of avoided CO2 emissions (cumulative 2010-2040, source: US Dept. of Energy). Scottsdale’s energy code updates include:

• Improved residential ceiling insulation and cool roof surfaces (low-slope roofs)
• High-efficacy lighting (LED or similar) for all lighting
• Interior lighting controls with dimmers or sensors excluding bathroom and hallways
• Exterior lighting controls with automatic shut-off when daylight is present
• Electric vehicle capable charging infrastructure (reserved breaker space and conduit) for new homes, apartments and hotels to support growing EV charging demand.
• Solar-ready roof tops for residential and commercial buildings (reserved breaker space and conduit)

The effective date for the International Energy Conservation Code (IECC) is Jan. 7, 2023.

The green construction code (IgCC) applies to all new commercial and multifamily buildings. Environmental benefits include conserving natural resources, improved air quality, enhanced occupant comfort and health, reduced waste streams, low environmental impactful materials and minimized strain on local infrastructure. Economic benefits include reduced operating costs, occupant productivity, life-cycle cost savings and improved property value. Social benefits include equity and access to improved quality of life. Scottsdale’s green code provisions include:

• Heat island mitigation for new hardscapes such as black asphalt parking lots
• Indoor and outdoor water use reduction
• Electric vehicle capable charging infrastructure for non-residential buildings
• On-site renewable energy (exceptions include equivalent energy efficiency improvements)
• Construction waste management (50% diversion of waste from landfill for recycling and reuse)
• Less impactful building materials (recycled content, regional resources, certified lumber and/or environmental product declarations)
• Improved indoor environmental quality (low VOC materials and finishes)

The effective date for the International Green Construction Code (IgCC) is July 1, 2023.
