Are you a co-op/condo board member, owner of a rental building or property manager of a residential building with steam radiators? Learn about cost-effective steps you can take today to improve your building, avoid fines and comply with LL97 in 2030.
Older residential buildings with steam heating systems are the most common building type covered by LL97’s carbon limits. Meeting these targets is too often framed as an all or nothing proposition, but for almost every co-op, condo and rental building energy efficiency is the place to start.
Here’s why you should act now:
- Get free money before it’s gone: Generous rebates and incentives will decrease after 2025 for certain types of upgrades.
- Avoid fines through 2034: Many steam radiator buildings can comply with LL97 through cost-effective improvements to current heating systems.
- Don’t miss two-for-one opportunities: Increase building value and comfort by adding LL97 upgrades to work you already plan to do.
For buildings that need to go beyond heating system efficiency work, there are targeted near-term projects that can help you avoid fines and set up your building for success beyond 2030. And no, we are not talking about replacing your entire heating system and spending millions of dollars.
