Building Energy Code Requirements Presented by: The leader in metal building insulation
Florida – ASHRAE 90.1 2004
ASHRAE 90.1 2004 Commercial Code: State developed code, Chapter 13 of the Florida Building Code, meets or exceeds ASHRAE 90.1-2001, mandatory statewide; can use Energy Gauge FLACOM to show compliance.
ASHRAE 90.1 2004 Florida 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 2004 Florida Semi-Heated Roofs and Ceilings: U value of .167 Walls: U value of .184 In “R” value terms it means the following: Roofs and Ceilings: In place R-6 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
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
