Submodules¶

eppy.constructions.thermal_properties module¶

Functions to calculate the thermal properties of constructions and materials.

eppy.constructions.thermal_properties.heatcapacity(ddtt)[source]¶: Heat capacity (kJ/m2-K) of a construction or material. thickness (m) * density (kg/m3) * specific heat (J/kg-K) * 0.001

eppy.constructions.thermal_properties.rvalue(ddtt)[source]¶: R value (m2-K/W) of a construction or material. thickness (m) / conductivity (W/m-K)

eppy.constructions.thermal_properties.rvalue_ip(ddtt)[source]¶: return R value in IP units

eppy.constructions.thermal_properties.ufactor(ddtt)[source]¶: U factor (W/m2-K) of a construction or material. 1 / R value (W/K)

eppy.constructions.thermal_properties.ufactor_ip(ddtt)[source]¶: U factor (BTU/(h °F ft^2)) of a construction or material. 1 / R value (ft^2 °F hr/Btu)
