Zeinloop
What it is
Zeinloop is a web and API platform for New York City building compliance, emissions tracking and retrofit planning. It is designed for property managers, building owners, asset managers and compliance teams, especially teams managing five or more buildings. The platform tracks LL84, LL87, LL88, LL97 and LL33/95, validates utility data, and displays sources, benchmark years, confidence, assumptions and limitations. Emissions monitoring covers electricity, gas, steam and fuel oil against LL97 limits, with monthly trends and 2030 forecasting. Building analysis shows current LL97 position, projected 2030 exposure and estimated annual penalty. A calculator models 2024–2029 penalty risk and retrofit scenarios. Zeinloop ranks HVAC, lighting and envelope upgrades by compliance return using penalty reduction, capital cost and payback. It can organise RDP-ready documentation, but official LL97 reports must be certified and submitted by a Registered Design Professional. Plans are priced by building, with custom portfolio proposals; pricing is on request.
