Big flat roofs and light, steady electricity use. Solar can cover most of the bill, and a battery trims the monthly peak.
What decides itRoof condition and how many years are left on it.
By building type
What works best for your type of building.
Each type of building uses power differently, so the best mix of energy sources changes too. These are typical results. Your Scorecard decides for each of your buildings.

At a glance
Every building type, side by side.
The usual best fit for each, and the one thing that most often changes the answer.
Industrial
Huge roofs and heavy, steady use. Solar takes the daytime energy charges; fuel cells carry the around-the-clock demand and keep lines running in an outage.
What decides itPeak demand charges, and gas price against your grid rate.
Hospital
Runs around the clock, uses heat all day and can never lose power. Fuel cells supply steady power on site; combined heat and power (CHP) turns waste heat into hot water and steam.
What decides itYear-round heat use and backup power requirements.
Hospitality
Hotels and resorts use hot water, laundry and cooling day and night. CHP covers the steady heat and power; solar on roofs and carports takes the daytime load.
What decides itHot water and laundry use, and open roof or parking space.
Retail · Malls
Long hours, heavy cooling and big roofs and parking lots. Fuel cells carry the steady demand; solar cuts daytime costs; storage trims the monthly peak.
What decides itPeak demand charges, and how leases split the energy bill.
Office
Heavy daytime use and big heating and cooling bills. Solar pays today; geothermal pays best when the HVAC is due for replacement.
What decides itWhere your HVAC system is in its replacement cycle.
