What's The Difference Between LL87, LL33, And LL84 Benchmarking?

 

Are you curious about the different types of benchmarking? Do you know which one to use for your specific needs? In this post, we'll break down LL87, LL33, and LL84 benchmarking so that you can understand the differences between them. We'll also provide tips on choosing the right type of benchmarking process for your business. Keep reading to learn more!

Local Law 87

New York City's building energy benchmarking law, Local Law 87 of 2009, requires covered buildings to track whole-building energy use by performing an energy audit, reporting to the city annually, and submitting to the city upon request.

The Department of Buildings (DOB) will use this data to generate an Energy Efficiency Rating (EER) for each building. The EER is a 1-100 index comparing a building's annual energy use to similar buildings nationwide. The US Environmental Protection Agency made a benchmarking tool as the Energy Star Portfolio Manager to help owners track a building's energy consumption.

An energy efficiency score of 70 or above indicates that a building performs better than at least 70% of similar structures; a score below 30 indicates that it performs worse than at least 70%.

All residential buildings larger than 50,000 square feet and all non-residential buildings larger than 100,000 square feet are required to benchmark. The law applies to the private sector and city-, state-, and federal-owned buildings. The goal of the law is to promote energy efficiency in large buildings, reduce greenhouse gas emissions from the building sector, and reduce energy consumption.

Local Law 33

New York City's Benchmarking Local Law 33 requires a covered buildings list to track their energy and water consumption data and report to the city annually. The law, which applies to buildings larger than 50,000 square feet, is designed to help reduce greenhouse gas emissions and promote energy efficiency.

By making large building owners aware of their energy use, the city hopes to encourage them to take steps to improve the efficiency of their buildings. In addition, the law requires the city to publicly disclose the energy performance and energy efficiency report of covered buildings, providing a valuable resource for both building owners and tenants.

As NYC continues its efforts to lead the way on climate change, Benchmarking Local Law 33 is an important step forward and is beneficial for the environmental protection agency.

Local Law 84

In New York City, Local Law 84 requires all large buildings to benchmark their energy use and report the data to the city.

The data helps commercial building owners compare their energy use to similar buildings, identify ways to improve energy efficiency grade, and track progress over time. The city also uses the data to develop policies and an energy star program to reduce greenhouse gas emissions.

In addition, the data is made available to the public, so everyone can see how NYC's buildings are performing. As a result of Local Law 84, NYC's buildings are becoming more energy-efficient, and the city is making progress toward its goal of reducing emissions by 80% by 2050.

LL87, LL33, And LL84 Benchmarking: The Key Differences

To start, let's quickly review what LL87, LL33, and LL84 are. LL87 is the energy benchmarking law for large buildings in New York City. LL33 is the energy benchmarking law for small to mid-sized buildings in New York City. LL84 is the energy benchmarking law for all buildings in New York State.

Now that we've got that out of the way, let's get into the differences between the three laws. The most obvious difference is that LL87 applies to large buildings, while LL33 and LL84 both apply to small to mid-sized buildings. But there are a few other key differences as well.

For one, LL87 requires that buildings track and report their energy use on an annual basis. LL33 and LL84, on the other hand, only require that buildings track their energy use once every three years.

Another key difference is that LL87 requires buildings to submit their energy use data to the city, while LL33 and LL84 only require that they submit their data to the state.

Finally, LL87 requires buildings to publicly disclose their energy use data, while LL33 and LL84 only require that they make their data available upon request.

So, what does all of this mean for building owners and managers? Well, if you're managing a large building in New York City, you'll need to comply with LL87. And if you're working a small to mid-sized building in New York City or New York State, you'll need to be compliant with LL33 or LL84.

You can always check with your local code enforcement office if you need help determining which law applies to your building. They'll be able to tell you which law applies to your building and what you need to do to be in compliance with retro-commissioning.
