Section CD601 Simulation of the Proposed Building Design
For the purpose of calculating the HVAC TSPR the following simple utility rate determined by the Washington State Department of Commerce shall be used:
- $0.112/kWh of electricity
- $1.158/therm of fossil fuel
The geometry of buildings shall be configured using one or more blocks. Each block shall define attributes including block dimensions, number of floors, floor-to-floor height and floor-to-ceiling height. Simulation software may allow the use of simplified shapes (such as rectangle, L shape, H Shape, U shape or T shape) to represent blocks. Where actual building shape does not match these pre-defined shapes, simplifications are permitted providing the following requirements are met:
The creation of additional blocks may be necessary to meet these requirements.
Exception: Portions of the building that are unconditioned or served by systems not covered by the requirements of Section C403.1.1 shall be omitted.
One or more blocks may be required per building based on the following restrictions:
At a minimum, the HVAC systems shown in Table CD601.11.1 shall be supported by the simulation program.
