In the early 2000s, a single map of U.S. climate zones was created based on analysis of U.S. weather sites identified by the National Oceanic and Atmospheric Administration (NOAA), as well as classifications of world climates. Cooling energy recovery in Climate Zones 3C, 4C, 5B, 5C, 6B, 7 and 8. 2. For each county in the United States the IECC defines a climate zone: Residential Provisions of the 2012 International Energy Conservation Code . Residential apartment/condo values may be slightly higher in some climate zones 2015 IECC –same as 2012 IECC Homerenergy.com IECC Climate Zones A Climate Zone Map can be found in the 2012 International Energy Conservation Code (IECC), funded by the U.S. Department of Energy- Energy Efficiency and Renewable Energy. Where the largest source of air exhausted at a single location at the building exterior is less than 75 percent of the design outdoor air flow rate. Climate Zone Map. Climate Zones 1-3 0.40 SHGC in Climate Zone 4 except Marine U-factors in all Climate Zones 2-8 Scope Section R101.4.3/R402.3.6 - Additions, Alterations, Renovations, Repairs 9 . is featured in all climate zones for all building types. The climate zone map was also adopted by ENERGY STAR for Homes in 2006. 26 Phase 2, ES5 Systems requiring dehumidification that employ energy recovery in series with the cooling coil. It first appeared in ASHRAE 90.1 in the 2004 edition. The 2004 IECC Supplement was the first model energy code to adopt this new climate zone map. builders to determine what climate zone applied to a specific building. Marine A marine climate is defined as a region that meets all of the following criteria: • A coldest month mean temperature between 27°F (-3°C) and 65°F (18°C) • … ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. Climate Zone Map • Align more closely with dominant model energy code – IECC and Title 24 (CA) ... – 2009 IECC (< 0.35) allows for trade-offs, IECC 2012 likely to as well – Products exist that meet criteria using current technology and argon gas – Low, moderate and high SHGC can all qualify. Use the “Outline of 2012 IECC Requirements” ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. Using the climate zone map to the right, match the jurisdiction to the appropriate IECC climate zone. IECC Climate Zones - Homer Energy. Again, equivalent alternatives are possible through the U-factor approach. Skylights: Climate Zones marine 4, 5, and 6 - U-factor amended from 0.55 to 0.60; Ceiling: Climate Zones marine 4 and 5 – R-value amended from R49 to R38 and U-factors from 0.026 to 0.030; Wood framed Wall: Climate Zone 6 – R-value amended from 20+5 or 13+10 to 20 or 13+5 and U-factors from 0.48 to 0.57 2012 IECC – economizer required on individual DX cooling units greater that 33,000 BTU/H; 2015/2018 IECC – economizer required on individual DX cooling units greater that 54,000 BTU/H; Figure 1. July 2011 . Use the simplified table of IECC building envelope requirements (below) to determine the basic thermal envelope requirements associated with the jurisdiction. The Building America subarctic climate zone corresponds to IECC climate zone 8. ASHRAE identified 38 climate zones for 240 cities, and IECC used 33 climate zones based on counties. U.S.
