Simulation Weather DataSimulation Weather Data24 hour profiles of actual weather data for all 365 days in a year DB, WB, direct and diffuse solar 8760 hours of real weather data

Data is used for Energy Analysis

SourcesNational Oceanic and Atmospheric Administration (NOAA), National Renewable Energy Laboratory

(NREL), Environment Canada, ASHRAE, national government weather services, and other sources

Variability of Weather Data Real weather conditions are diverse Any one month has a wide range of conditions Hot, cold, humid, dry, sunny, cloudy Results using average profiles are less accurate than those calculated using TMY

weather data TMY Data is NOT average, it is a Typical Meteorological Year

Simulation data differs from design" weather data Used loads are run for 1 design day each month using warmer than normal temps and clear sky

solar. The purpose of simulation is to compare energy costs of alternate designs ... the purpose of

loads is to determine required sizes for HVAC system components.

Window - Overall U ValueWindow - Overall U ValueHAP and ASHRAE 90.1-2007 use overall U value. This defines the heat transmission of the entire window assembly, including glass and framing

HAP accounts for heat flow through the center of glass, edge of glass, window frame and any internal shades.

Overall Shade Coefficient (SC) Versus Solar Heat Gain Coefficient (SHGC)Overall Shade Coefficient (SC) Versus Solar Heat Gain Coefficient (SHGC)

87.SHGCSC =

Shade coefficient describes how much solar energy is transmitted through the window glass and framing. Solar Heat Gain Coefficient (SHGC) represents the solar gain through the glass relative to the incident solar radiation .

In simple terms, the shade coefficient is a ratio of solar transmission for the window divided by solar transmission through a single pane of reference glass. It therefore accounts for the difference between the optical properties of your specific window design, framing and interior shades versus the properties of reference glass. When using the detailed input approach in defining a window, HAP calculates the overall shade coefficient using ASHRAE and NFRC (National Fenestration Rating Council) estimation procedures. These procedures consider solar energy transmission through the glass portion of the window, solar heat absorbed and transmitted through the window frame, the effects of heat absorbed by glazings in the window assembly and the effects of internal shading devices.
