COMMERCIAL BUILDING ELECTRIFICATION

The extent of commercial building electrification across the US

Electrification is making gradual inroads into US commercial buildings. For now it is confined to a small number of cities, mostly to municipal buildings, and mostly to new construction. But drivers including city building codes, municipal procurement rules and air quality regulation will have implications for certain cities — public and private buildings alike — over the coming years.

RESONANCE INSIGHT
Very few cities so far mandate all-electric. Most only require energy reporting or efficiency levels that a good gas unit already meets.
Where mandates do exist, most cover municipal buildings only. Privately owned offices, hotels and apartment blocks are untouched.
Only three of the six require all-electric in privately owned buildings. San Francisco covers new build and major renovation. Seattle covers new build, and hotels and apartment blocks when the hot water system is replaced. Denver covers new build, and replacement only where an electric alternative proves cost effective.
Only one of the three has no way out. Seattle lets a building keep gas if it buys enough efficiency credits. Denver bars gas water heaters but still allows the gas boilers that serve the same load. San Francisco has no equivalent exit.
What triggers the rule matters more than how many buildings it covers. A city that requires electric when equipment breaks down reaches four to six times more buildings a year than one that only applies to new construction.
A heat pump requirement does not mean the gas comes out. Codes typically allow existing gas plant to stay as back-up or to meet peak demand.
Some cities have scrapped their mandates. One repealed its rule and backdated the repeal.

RESONANCE INSIGHT
Ten of the eighty largest US cities have an all-electric mandate in force today. Two more came out of that count during the last review — one had repealed its ordinance, and one turned out never to have adopted a requirement at all.
Only two of the eighty largest cities have a dated requirement still ahead of them. The rest of what is coming is not from city halls. It is from air districts and states, and it reaches existing buildings when equipment is replaced.
Others are stuck, and some are going backwards. Some are in the courts, some were passed but never written into the rules, some are being sued by the federal government — and in one state every city ordinance we checked has been repealed, suspended or left unenforced.
The rules arriving next are harder to plan around. They reach privately owned buildings, and they bite when equipment is replaced rather than when something is built.
WHAT IS STUCK, AND WHERE
Federal courts — two circuits now disagree
A voter initiative before a state supreme court
Mandates passed but never written into the rules
Cities being sued by the federal government
Air district rules under review
A statewide standard that has not reached its own board

WHAT SUBSCRIBERS GET
Every dated requirement through 2040, by year and by city — with the floor area behind each one, so demand can be phased and sized rather than guessed.
Where the next wave is coming from. Most of it is not city building codes, and it reaches existing buildings when equipment is replaced.
Where gas still complies, even in cities reported as all-electric.
Which building types are exempt — including the ones with the heaviest hot water loads.
What is at risk of going backwards. What sits in the courts, on a ballot, or has already been repealed.
