The answer was closer than he knew. Energy Points, a Boston company, had developed an algorithm it claimed could do just that. So last year Lasker fed three years' worth of data on heating, cooling, electricity, waste, and water from the MBTA's four oldest bus garages into EnergyPoints Analytics software -- which translates the energy contained in various sources into a single common unit -- and started asking hypotheticals. At the Quincy facility, an old horse-and-carriage garage built in the early 1900s, he learned the MBTA could save $112,121 and the energy equivalent of 29,561 gallons of gasoline in just one year by switching from fuel oil to natural gas for heat.
