Consider whether high-SRI materials are appropriate for any given application. Partcularly for occupiable roof spaces and roofs adjacent to glazing, there is a danger that some roofing materials will be too reflective, and cause glare problems. Not all high-SRI materials are the same in this regard because the metric is determined by both reflectivity and emissivity, so examine your choices for materials that work well.

Recalibrating the energy model to match the actual energy use of tenant spaces will add some cost to your project. Recalibration should be done 10 to 12 months after occupancy, and the added cost should be minor if it only involves something like adjustin

Recalibrating the energy model to match the actual energy use of tenant spaces will add some cost to your project. Recalibration should be done 10 to 12 months after occupancy, and the added cost should be minor if it only involves something like adjusting occupancy hours. However, note that unforeseen complexities can drive up these costs. 

The payback period for an M&V program depends on the initial cost of additional meters and whether the system identifies inefficiencies that wouldn’t have been found otherwise. Some fixes may be substantial enough to pay for the metering system. After

The payback period for an M&V program depends on the initial cost of additional meters and whether the system identifies inefficiencies that wouldn’t have been found otherwise. Some fixes may be substantial enough to pay for the metering system. After your BMS or submetering system has been installed, true return depends on the commitment of the owner and operations staff to making the best use of the system.
