Total Rent Paid to Owner

Carbon Lighthouse pays rent to owners for access to remote sensors.

Lifetime net cash to owners and tenants

We work in all lease types to ensure the landlord benefits as well as tenants:

  • NNN: If tenants pay utility costs, we create a service contract paid by tenants, and then we pay owners rent for ongoing building access and sensor placements, similar to a cell antenna lease structure.
  • Full-Service Gross: If the landlord pays all utility costs, then we create a service contract to deliver an agreed upon level of savings. The owner receives the full value of savings accrued and pays the service contract.

Owner ROI

ROI is calculated dividing the total net cash to owner by total service cost to owner

Increased disposition value

  • Owners realize an average increased disposition value of $5-$10 per square foot by capping the increased NOI
  • An easy exit is always at hand, whether you buy out the contract or the new owner assumes Carbon Lighthouse’s service contract
