Using an integrated design process, the team can easily reduce energy usage below ASHRAE 90.1-2007 thresholds. When designing the lighting layout, the team can take into account the daylighting design of the space in order to reduce the number of fixtures and lower the wattage. The architect can finish the interior space to further enhance lighting efficacy and reduce dependence on mechanical cooling and heating. If appropriate, the mechanical designer should evaluate underfloor air distribution or radiant heat instead of ducted air for higher efficiency.
