The project RFP included an absolute energy use intensity target for energy consumption, a net zero energy balance target, and a minimum 50% energy savings versus a minimally code-compliant equivalent building with the same unregulated loads and program. This requirement necessitated construction of a baseline building model, built according to the requirements laid out in Appendix G of ASHRAE 90.1-2004, which include distributing glazing in equal bands around the building, eliminating shading devices, modeling a standard HVAC system type with airside economizers and screw chillers with a coefficient of performance of 4.9, and using standard lighting power densities per space type. U-values of the opaque envelope and glazing assemblies were taken from ASHRAE 90.1-2004 Table 5.5-5. In the baseline case, computer workstations were assumed to consume 120 Watts versus the 65 Watts in the low energy case.
