Local Law 97 Update


As most NYC apartment owners and managers know, the City of New York enacted Local Law 97 (LL97) in 2019 as a part of the Climate Mobilization Act. This forward looking law places carbon caps on most buildings larger than 25,000 square feet—roughly 50,000 residential and commercial properties across NYC. These caps start in 2024 and will become more stringent over time, eventually reducing carbon emissions 80 percent by 2050.

Heat-Timer® has been actively involved in the discussion around LL97 and has provided assistance to hundreds of NYC building owners as they plan for compliance to the law and seek to avoid increasing penalties for non-compliance.

Recent Local Law 97 Updates 

The rules around NYC local law 97 are complex and reflect a timetable that allows building owners time to get their properties analyzed and solutions proposed and budgeted. On October 6, 2022, the NYC Department of Buildings released a new document called Proposed Rules for Local Law 97 that answers and clarifies more questions about the law’s requirements through 2050. 

Here are a few key take-away’s from the update, which building owners need to know.

1. 60 NEW PROPERTY TYPES ADDED FROM EPA’S PORTFOLIO MANAGER

The EPA’s Portfolio Manager, is the well-established tool for tracking building energy use. LL97 originally set 10 emissions limits based on Building Code occupancy group classifications. The proposed rules expand those categories based on Portfolio Manager, which includes dozens of different property types that more accurately reflect the variation in energy use among buildings. 

2. BUILDING EMISSIONS LIMITS SET FOR ALL PROPERTY TYPES TO 2050 AND BEYOND

The proposed rules assign new emissions limits for each new property type from 2030 through 2049. From 2050 onward, a zero emissions requirement applies to all property types—a move that aligns to global 1.5°C climate targets. For 2024 to 2029, the proposed rules preserve LL97’s original 10 emissions limits but distribute those limits across the 60 Portfolio Manager property types, creating better-tailored targets for all buildings.

3. A 2030 ELECTRICITY CARBON COEFFICIENT THAT REFLECTS THE GREENING GRID AND SUPPORTS ELECTRIFICATION

The electricity carbon coefficient is used to calculate the carbon content of the electricity that a building consumes each year. The proposed rules specify an electricity coefficient for 2030 to 2034 that is about 50 percent lower than the one that applies for 2024 to 2029. This change reflects major new clean energy coming to NYC in the next few years, bringing rapid decarbonization to reach New York State CLCPA targets. 

4. RECS CAN ONLY OFFSET EMISSIONS FROM ELECTRICITY USE

LL97 allows building owners to deduct or offset annual building emissions through the purchase of renewable energy credits (RECs) for local green power. The proposed rules clarify that these deductions are limited to emissions from building electricity use, which would ensure that credits for the purchase of green electricity aren’t used to offset fossil fuels burned onsite for heat and hot water.

Heat-Timer® Can Help with LL97 Compliance



By reducing the energy consumption of your heating systems by up to 30%, Heat-Timer® Platinum Series Boiler Controls and our newly released Genesis Heat-Timer control can go a long way to reducing your carbon footprint and meeting the increasingly stringent requirements of LL97. Best of all for New York customers, there are rebate programs which most utility companies are providing that can offset a major part of the cost of heating control installation. A current list of rebate incentives available to New York Customers is available at the NYSERDA website.

How Heat-Timer® Controls Can Make Your Building Management System Better

A  Building Management System  (BMS), also called Building Automation System (BAS) is a system that allows building managers to monitor and control a building’s major mechanical and safety systems in one central, easy-to-use application. A BMS can be thought of as a distributed network of building systems supervised and controlled in one central platform. The network of field controllers and other system controllers are distributed throughout the building and communicate to the BMS through a local area network. Field controllers can be general purpose, supplied by the BMS integrator and used for simple applications like lighting control, ventilation fans and building access. With a BMS, these applications can also be separated by zone, floor or other combinations to yield optimal HVAC performance. Field controllers for mission critical systems like fire alarms and heating are specialized and can act independently, as well as under BMS control. The Heat-Timer® Platinum se...

Water Safety For all Time

Image
Because of regulations put in place after the outbreak of legionnaire’s disease in the 90’s, installation of Domestic Hot Water (DHW) systems were changed for the sake of public safety.  All DHW systems, whether storage based or tankless, must now meet the conflicting requirements of holding DHW at a minimum of 140°F (60°C) to comply with such standards as OSHA Technical Manual Section 3 Chapter 7, to combat Legionella growth, while delivering hot water at a temperature that prevents scalding injuries in sinks and other fixtures. For decades, commercial plumbing installers have embraced a 3 way mixing valve or “tempering valve” as the perfect solution to the dilemma. Early tempering valves were controlled manually with fixed setpoints, but in 2020 we have evolved to using motorized valves under the direction of a standalone electronic control station that adds flexibility, reduces energy use, provides alerts and alarms, and generally improves the safety of any domestic ...

Heat-Timer’s Wireless Sensor Integration Just got a Big Upgrade

Image
  One of the most appealing parts of the Heat-Timer® Platinum Series is the wireless sensor connectivity that comes with our Building Net internet upgrade. There are thousands of clients who own an original, non-internet capable Platinum Series control and when they upgrade the control with our Building Net internet package they actually get two major elements: An Internet/Mobile ready control – The Building Net upgrade gives any platinum control the ability to be controlled via the internet through a simple browser connection to a web management portal, or via our free mobile app. In either case, reports, alarms, control settings, and real-time monitoring are all at your fingertips, wherever those fingertips may be. Wireless Sensor Integration – You can think of this as the second network access that is enabled by the Building Net upgrade. This internal Long Range network allows you to connect our wireless space sensors to the control, which by reporting temperatures in vari...
