Block after block, the same scene can be seen if you stroll through any mid-sized American downtown after dark. Office buildings are dimly lit. Empty floors are humming with ventilation systems. A conference room with lights on since 2008 is being passed by a janitor pushing a cart. The conventional reaction to this waste was optimistic for almost twenty years. Change the lightbulbs. Adjust the boilers. Put in a more intelligent thermostat. The savings would come next. They did for a time. Almost no one outside of the industry seems to have noticed that story has quietly stopped working.
The figures lack the dramatic quality that climate stories typically require. There is neither a burning forest nor a flooded coastline. On a chart that used to slope downward, it was just a flat line. Buildings that made consistent investments during the 2010s are now experiencing yearly efficiency gains of less than one percent, as opposed to the previously common 2.2 percent. Thousands of organizations are monitored by the Department of Energy’s Better Buildings program, and the trend is so consistent that it is no longer really debatable. There is a plateau.

The math of what commercial buildings still represent is what makes this an underreported emergency rather than merely a slow news story. about 20% of the country’s energy consumption. at least half of a city’s greenhouse gas emissions. The percentage rises to 75% in New York. According to a Pacific Northwest National Laboratory study, commercial buildings in the United States could reduce their energy consumption by an average of 29% if current controls were fully implemented. For years, that study has been on the shelves. There is still a chance. It has the will to pursue it.
Simple economics is part of the issue. The initial retrofits quickly paid for themselves. The percentage of commercial buildings with LED lighting increased dramatically from 9% in 2012 to 44% in 2018. The savings were immediately apparent in operating budgets. The next step is more difficult. Deep envelope work, electrification of legacy gas systems, and heat pumps. Larger checks, longer payback periods, and a type of capital conversation that most facilities teams are ill-prepared to have with their CFOs are all necessary for these. The hurdle rates remain unchanged.
The more subdued offender is the fact that buildings are constantly coming up with new ways to use electricity. Storage rooms were once server closets. The parking garage has EV chargers. Every employee now brings a standing desk fan and two monitors from home. The spreadsheets that supported the most recent efficiency project hardly ever include these additions. They simply appear on the meter.
On paper, it’s difficult to ignore how simple it is to make the plateau vanish. Normalization of the weather can accomplish this. Adjustments to occupancy can also be made. When the underlying system has completely stopped improving, a facilities director may show a board a chart that appears to show progress. It is not neutral information to have two flat years with the same occupancy and operating hours. It serves as a caution. The majority of organizations do not currently interpret it that way.
Observing this gives the impression that the nation secretly believed efficiency would continue to carry out the tasks that behavior and policy would not. It can’t. The structures remain intact. The meters continue to spin. Additionally, the majority of the simple victories that formed the foundation of the urban climate progress narrative have been gathered.
