Short Payback Retrofits Win Budgets
Lee Hoffman, co-founder of Runwise, on the operating system for buildings
The buying trigger in building tech has shifted from climate compliance to immediate cash flow. Owners are not shopping for abstract efficiency projects, they are buying tools that cut utility bills, avoid emergency costs, and raise NOI within months. That favors software and controls retrofits over big equipment swaps, because wireless systems can be installed fast, priced lightly upfront, and measured against the next utility bill.

Runwise built its sales motion around short payback, using wireless controls that go in within a day or less and targeting savings large enough to outweigh fees in year one. The product then expands from heating into cooling, leaks, toilets, and gas monitoring, which adds more savings without another major install.

This is also why lighter retrofits are winning budget over deep retrofits. Replacing boilers, windows, or whole HVAC systems can be good economics over time, but those projects are expensive and slow. Controls software changes how existing equipment runs now, which matters more when rates are high and landlords are capital constrained.

Regulation still helps, but mostly when it lines up with operating pain. New York City Local Law 157 created a deadline for gas detection in residential buildings, and Runwise turned that requirement into one more software linked sensor on the same network. Utilities also subsidize efficiency projects, which further shortens payback for owners.
The next phase is that the fastest paying products become the wedge into a broader building operating stack. Once a wireless control layer is already in place, more safety, maintenance, and grid response software can ride on top of it. The company that proves payback first is best positioned to become the default system running older building stock.
