Building Energy Code Requirements Presented by: The leader in metal building insulation
ASHRAE 90.1 2004 Commercial Code: 2003 IECC with reference to ASHRAE 90.1-2001 is mandatory statewide. The State Engineer's Office and the SC Department of Education have adopted the ASHRAE 90.1 1999 as the energy code for state buildings and schools and buildings under their jurisdiction. Can use COMcheck-EZ to show compliance.
ASHRAE 90.1 2004South Carolina • Heated (condition buildings) • Roofs and Ceilings: U value of .065 • Walls: U value of .113 • In “R” value terms it means the following: • Roofs and Ceilings: In place R-15.3 • Walls: In place R-9
Insulation compression and reduction of R-Values A loss in R-Value occurs when the insulation is compressed between the roof and walls structurals and the exterior metal skin.
Metal Building Roof Requirements Conditioned Building In order to achieve a U-Value of .065 (in place R-15.3) in the roof the following is required • 6” of R-19 metal building fiberglass insulation • Thermal Blocks – are required • This will achieve an in place R-value of R-15.4
Metal Building Wall Requirements Conditioned Building In order to achieve a U-Value of .113 (in place R-8.9) in the walls the following is required • 4” of R-13 metal building fiberglass insulation • Thermal Blocks – not required • This assembly will achieve an in-place R-Value of R-8.9
ASHRAE 90.1 2004South Carolina • Semi-Heated • Roofs and Ceilings: U value of .167 • Greenville-Spartenburg area: U value of .097 • Walls: U value of .184 • In “R” value terms it means the following: • Roofs and Ceilings: In place R-6 • Greenville-Spartenburg area: In place R-10 • Walls: In place R-5.5
Metal Building Roof Requirements Semi-Heated Building In order to achieve a U-Value of .184 (in place R-6) in the roof the following is required • 3” Thick of R-10 metal building fiberglass insulation • Thermal Blocks – are not required • This will achieve an in place R-value of R-6.5 • Greenville-Spartenburg: In Place R-Value of R-10.3 • Need to use 6” of R-19 insulation w/o thermal blocks to achieve a in place R-value of R-10.2 • Or in a Standing Seam Roof 3” of R-10 insulation with thermal blocks to achieve a in place R-value of R-10.3
Metal Building Wall Requirements Semi-Heated Building In order to achieve a U-Value of .184 (in place R-5.5) in the walls the following is required • 3” of R-10 metal building fiberglass insulation • Thermal Blocks – not required • This assembly will achieve an in-place R-Value of R-7
