Revision history [back]

I would tell the building owner that energy modeling alone will save him zero dollars. I would subsequently recommend he find a commissioning agent if he wants to save real $.

It really depends on the type of building, the energy modeling scope and who is creating the energy model. Most importantly, it depends on how the building is operated in the real world, outside of the simulation tool.

Unfortunately, I think an energy model has little impact on verified post-occupancy energy savings. While an energy model is a great tool for guiding the design team it does little to ensure that the design is properly executed and the building is operated efficiently. I often find "high performance" buildings operating very poorly when I retrocommissioning them because the systems are too complicated for the facility personal to operate properly.

Assuming the owner cares about actual performance, not design performance...
