Proven Track Record in Energy Reduction
- Average Energy Savings: [A line graph showing an average of 15% to 30% reduction in annual energy consumption (steam, oil, gas, electricity) for client buildings after BMS installation]
- Rapid ROI: Many clients achieve a full return on their BMS investment within [Financial data table showing ROI timelines for various project sizes]
- Compliance Assurance: Our systems provide the granular, verifiable data necessary for accurate LL97 reporting and continuous performance monitoring.
National Reach, Local Expertise
Specialized BMS Solutions for Every Building
Retrofit Solutions for
Older Buildings
Older buildings, which often struggle most with LL97 compliance due to outdated systems, are our specialty. Our BMS acts as a smart, modern layer of control over existing equipment, drastically improving efficiency without requiring a full mechanical overhaul.
Implementing intelligent boiler controls and heating system sensors to precisely match heat output to demand, reducing steam, oil, and gas consumption.
Dividing large buildings into smaller thermal zones with independent temperature controls to prevent overheating and energy waste.
Non-disruptive integration with existing legacy equipment (HVAC, lighting, and metering) to provide centralized control.
Optimization for New Construction
BMS Implementation for Direct LL97 Compliance
LOCAL LAW 97 FAQs
NYC Local Law 97 (LL97), passed in 2019 as part of the Climate Mobilization Act, is one of the most ambitious climate laws in the United States. It aims to reduce greenhouse gas emissions from buildings — which account for nearly 70% of New York City’s carbon footprint — and achieve carbon neutrality by 2050. The law sets strict emissions limits based on building size and occupancy type, pushing property owners toward sustainable and energy-efficient operations.
To enhance safety, New The following buildings are subject to the requirements of LL 97:
- Buildings that exceed 25,000 gross square feet
- Two or more buildings on the same tax lot that together exceed 50,000 gross square feet.
- Two or more buildings held in condominium ownership that are governed by the same board of managers and that together exceed 50,000 gross square feet.
- Certain buildings, including: City-owned buildings, classified religious places of worship, nonprofit hospitals and healthcare facilities, and buildings with a certain threshold of rent-regulated dwellings, may be exempt.
- Buildings owned by cooperative corporations that meet the above criteria are subject to the requirements of LL 97.
The city has provided an Operations & Maintenance Best Practices guide – A Guide to Achieving Operational Efficiency. You can instantly download the guide by clicking here.
Small operational changes can lead to energy savings; however, building owners should bring in a licensed consultant to conduct an audit for larger cuts to carbon emissions. The consultants will identify equipment (i.e., heating, lighting, and cooling systems) that should be replaced or upgraded.
Your carbon footprint is determined by your building’s total energy usage, which includes building systems and tenant usage. Examples of energy usage include: Natural Oil, Natural Gas, Electricity, Fuel Oils, and District Steam.
Depending on the size and use of your building, an energy use threshold is established with buildings expected to reduce their usage from this level progressively over the years. Reduction of carbon emissions is in itself a multi-faceted problem which involves benchmarking, identifying high energy use areas of the building and implementing solutions to reduce this usage. For buildings that do reduce their emissions, the payoff comes in the form of reduced energy use.
