Replacing an NYC building boiler with heat pumps requires more than equipment selection. Learn how heating loads, distribution temperatures, electrical capacity, ASHP and WSHP options, controls, phasing, and Local Law 97 targets shape the right solution.
Local Law 87 requires covered NYC buildings to complete an energy audit and retro-commissioning every ten years. Learn what owners should expect—from confirming the due date and preparing records to field testing, corrective work, and filing the Energy Efficiency Report.
Retro-commissioning helps building owners identify operational problems, control issues, and energy waste in existing systems. Learn how the process differs from maintenance, what warning signs to watch for, and when an RCx investigation makes sense.
