Microgrids and IoT Integration

Matthew Mininberg

August 2, 2021

Microgrids are self-sufficient, low-voltage energy distribution systems that consume and produce electricity autonomously from the greater electricity transmission grid. These systems comprise a series of managed electric loads such as lighting loads; heating, ventilation, and air conditioning (HVAC); elevators; and electric vehicles among other things. They also include distributed power sources like small scale wind turbines, Solar PV, hydrogen fuel cells, geothermal, heat pumps, Combined Heat and Power (CHP) or Co-Gen, as well as battery storage. Microgrids typically serve a small geographic community independent from the transmission grid, known as being in “island mode.” This is due to the technical, financial, and regulatory difficulties associated with pricing and maintaining electricity flow between the microgrid and the larger public grid. That being said, microgrids can also be connected to the public grid through a “grid-connected mode”, which means there is the potential for a two-way flow of power.

Microgrids are becoming increasingly commonplace in North America. They have shed their niche appeal, migrating from the pioneering edges of society and into urban centers as self-reliant enclaves of technological dynamism and climate resilience. These forays mark a rapid transformation in how cities generate, supply, and distribute electricity. They also demonstrate a change in how business leaders, community architects, building owners and facility managers think about electricity consumption and pricing.  However, the growing prominence of microgrids is not only powered by ESG investments or progressive government policy, but also by leaps in IoT innovation.

Smart meters are becoming the bedrock for measuring and managing the complex data streams associated with energy production and consumption in microgrids. By disaggregating loads by end-use, smart meters provide detailed information regarding the microgrid community’s energy profile and recorded consumption. All that data can then be processed and organized using an energy data hub, which in turn enables microgrid managers and building owners to engage in energy management. Moreover, active grid management using smart metering data can make it easier to match onsite energy production with energy use. This translates to less energy wasted, fewer dollars spent and more system resilience. By balancing energy production with consumption, the microgrid will not only operate more efficiently, it will also be more flexible and better equipped to handle dips in power output.

From a supplier standpoint, the IoT integration of smart metering and microgrids makes it easier to remotely collect energy data for billing. This is because new advanced revenue-grade smart meters allow building owners and billing companies to pull real-time meter reads to generate accurate and reliable invoices. This plays a big role in ensuring the microgrid not only avoids unseen technical and nontechnical losses, but also that it stays financially viable by keeping the cost of providing energy services low.

Energy digitization, automation and intelligent IoT driven microgrids may seem like far off fantasies, but in reality, they drive a lot of today’s innovations in energy infrastructure. By supporting the deployment of microgrids that utilize smart meters and IoT, we not only benefit from having accurate, reliable, and affordable energy services, but also from clean, sustainable, and climate-resilient communities.

Your Top 7 Questions on Local Law 97 Answered!

By Matthew Mininberg

October 7, 2020

1.  What Does Local Law 97 Do?


Develops GHG Reduction Requirements.

Local Law 97 states that ‘covered buildings’ must cut their aggregate GHG emissions by 40% by 2030 and further still to 80% by 2050 as related to their emissions from the base year 2005. These goals also apply to buildings owned by the New York Housing Authority (NYCHA). However, the City government must achieve a 40% emissions reduction by fiscal year 2025 and up to a 50% reduction by calendar year 2030 (using the same base year of 2005).

Creates a New Office to Oversee Energy Efficiency.

To ensure that these targets are achieved, Local Law 97 also establishes a brand-new governmental office— the Office of Building Energy and Emissions Performance (BEEP). The Office has been tasked with administering the implementation and oversight of the City’s building energy and emissions performance laws for both existing buildings and new construction/major renovation.


2.  How Does Local Law 97 Define Building Emissions Intensity?

A building will be considered compliant with Local Law 97 when its emissions intensity is less than the set limit. A building will be non-compliant and fined if they go over the limit. Building limits are set for 5-year periods starting in 2024 through to 2034. Building limits for after 2034 have yet to be set. A building’s emissions limit is determined by “occupancy group”, which can be found on the U.S EPA’s Energy Star Portfolio Manager.  

Building Emissions Intensity = Total Building Emissions / Gross Floor Area

To determine your building emissions intensity limit, you must divide your building’s total emissions by the building’s floor area as expressed by metric tons of CO2 equivalent per ft2 per year (tCO2e/ft2).

To calculate your building emissions for Local Law 97, multiply your GHG emissions coefficient by the amount of energy used in the building. However,the GHG emissions coefficient will depend on what type of energy your building consumes. GHG coefficients will also change with each new emissions limit period (they are specified through to 2034) and are displayed individually on the Local Law 97 document.

Remember that your building’s total emissions are the sum of all calculated building emissions for the types of energy consumed.

Building Emissions = GHG Coefficient x Total Energy Usage


3.  Can I Make Deductions from My Total Emissions?

Building owners may make three types of deductions from the total amount of GHG emissions they report.

          1.  Purchasing GHG offsets: The deduction is equal to the metric tons of CO2 equivalent purchased.

          2.  Purchasing renewable energy credits (certificates): The deduction is equal to the amount of credits purchased.

          3.  Use clean,on-site distributed energy resources: The deduction is equal to the calculated output of the clean distributed energy.

          4. Are There Annual Reporting Requirements?

Building owners must file an annual energy compliant building report with BEEP. The compliance report must first be certified by a registered design professional and state the building’s compliance status with the emissions limit during the previous calendar year.  Reporting shall begin on May 1st,2025 and will continue annually each May.


5. Who Needs to Comply with Local Law 97?

Local Law 97 only places GHG emissions reduction requirements on“covered buildings.” Meaning buildings that exceed 25,000 ft2, properties with two or more buildings which together exceed 50,000 ft2, or two or more condominium buildings overseen by the same board of managers that together exceed 50,000 ft2. Exceptions include: power generation facilities, ‘city buildings’ (buildings owned by the City), rent regulated accommodations, religious places of public worship, housing development fund properties and properties less than 3 stories where each dwelling unit is held by an individual owner.


6. What Happens If I Can’t Comply with Local Law 97?

If you exceed the annual building emissions limit set for your occupancy group, then you are liable to face a fine of an amount equal to the difference between the emissions limit for that year and the reported building emissions, multiplied by $268.

There is also a financial penalty for not filing the report at all. This being an amount equal to your gross floor area, multiplied by $0.50,for each month that you don’t correct the violation.  However, if you file a late report demonstrating compliance then you are granted a 60-day grace period.

Providing a false statement will be considered a misdemeanor and will therefore include a fine of not more than $500,000, or imprisonment of 30 days or less, or could receive both the fine and imprisonment. Additionally,you could be liable for a civil penalty of not more than $500,000.


7. When Does Local Law 97 Take Effect?

Local Law 97 was enacted on May 18, 2019 and took effect on November 14th, 2019. Emissions caps do not go into effect until 2024.

NYC Shines Brightly on Energy Efficiency: What Building Owners Should Know About the Climate Mobilization Act

By Matthew Mininberg

October 7, 2020

Under the towering skyscrapers of Manhattan, Energy Efficiency seems to finally be getting its day in the sun. For years, the rapid growth of renewable energy has captured the attention of the American public. Most people even agree that increasing America’s use of renewables is a good thing. A Gallup Poll from March found that most Americans agree that more emphasis should be placed on renewable energy production (80% for solar and 70% for wind) and want to reduce fossil fuel use (60%) to combat climate change.

However, what is talked about much less, is the important role that energy efficiency has in lowering America’s greenhouse gas emissions (GHG). Becoming more energy efficient might even be the best thing the United States can do to cut GHG emissions. A report published in October by the American Council for Energy-Efficient Economy (ACEEE) found that energy efficiency opportunities like installing smart meters could reduce expected 2050 US GHG emissions by as much as 50% and could cut primary energy use by 49%. That’s not just a lot of emissions savings- it’s also a lot of dollars.

Several cities are already incorporating energy efficiency into aggressive plans to combat climate change, but no American city is doing more than New York. Its Green New Deal, the Climate Mobilization Act (CMA), is the first major piece of legislation specifically designed to place energy efficiency at the center of its plan to lower the City’s GHG emissions.  


CMA is one of the most ambitious and significant climate actions undertaken by any major city in the world. It matters even on an international level because New York City has a GMP of about $1.5 trillion. That makes New York City among the world’s twenty largest economies, just shy of Canada and Spain’s national economies.

CMA is a massive undertaking, occurring in an immense economy. However, it isn’t just one piece of legislation. CMA is actually a legislative package of 9 bills meant to align the City with its 1.5 °C Climate Action Plan— “to advance the Paris Agreement goal of limiting global temperature rise to 1.5 degrees Celsius”. All 9 bills were enacted into law on May 18, 2019, becoming Local Laws 92, 93, 94, 95, 96, 97, 98, 99 and 100.  These laws set the City on a path towards achieving carbon neutrality by 2050. While CMA may seem overwhelming, only Local Laws 95 and 97 need to be understood in order to know how CMA affects energy efficiency.  


New York City’s big buildings use an enormous amount of energy for heating, cooling, lighting and other operations. By cutting a building’s energy use, less GHG emissions are emitted because less power needs to be generated for the building to carry out its operations. It is critical that New York City’s buildings become more energy efficient considering they account for about 67% of the City’s total GHG emissions. What’s more, a report by Align-New York and its partners found that just 2% of the City’s buildings consume 45% of its energy. To put a significant dent in New York City’s GHG emissions, the Office of the Mayor and New York City Council must rapidly improve the energy efficiency of large buildings.

There is no question that achieving the targets laid out under Local Law 97 will take considerable effort. However, it is important to remember that because the base year used in Local Law 97 is 2005, it is more than likely that your building has already become more energy efficient since then.

Understanding the benefits of residential submetering

August 21, 2018

What is Submetering?

Submetering is the use of electrical metering devices with the ability to measure energy usage in each apartment, after the building primary service utility meter.

Submetering tenant spaces is beneficial for both property owners and tenants. Landlords (note that in coops and condos, the tenants are the owners) benefit from increased tenant engagement, reduced resource consumption, and eligibility for Energy & Atmosphere LEED credits. Tenants can use submeter data to monitor daily usage, ensure accurate billing, reach sustainability goals, and reduce their utility bills. In addition, the master meter enables shopping for less expensive and “Green” power from ESCO’s, and buying in bulk often qualifies the building for lower rates. Why pay “retail” rates with an individual (aka “direct”) meter when a master meter provides “bulk” or “wholesale” rates.

1. Seamless and Accurate Tenant Billing

In some states, in multifamily buildings, it is permitted to charge each tenant a portion of the building total energy bill equivalent to the square footage that tenant occupies. However, this standard industry practice is inherently unfair to both owners and tenants and results in unfair billing. For example, if a laundromat (an energy-intensive business) and a retail shop (not energy-intensive) occupy the same square footage in a building, they pay an equal share of the electric bill, even though one tenant consumes much more than the other; or, if two apartments of equal square footage have different size families, they would both be charged the same amount even though the usage is quite different. Other real-world examples include tenants who have more than one residence, and may be spending a week or season in another home and use little or no kWh consumption in the un-occupied apartment, but they would still be charged based on the occupied space. The problem here is that tenants are not billed based on consumption behavior, rather, they are billed based on the total consumption of the rest of the tenants - this is known as “RUBS” (Ratio Utility Billing Service) where permitted.

That is one reason why, in NY state, new construction multi-family buildings must have either direct utility meters or submeters for each apartment. The NY State Energy Research and Development Agency (NYSERDA) has shown that residents of an un-metered apartment (where the rent includes the utility cost, aka “rent-inclusion”) will use 10% - 30% more electricity compared to the same apartment when a submeter is installed. The reason is obvious, since the rent does not increase when more electricity is used or wasted.

With submeters, landlords can instead charge each tenant for their exact consumption during a particular billing period, rather than making an arbitrary and time-consuming estimation.

2. Identifying Inefficiencies

As energy management becomes more important to companies that operate large buildings and facilities, the need for detailed information on how energy is used increases. Submetering of spaces and equipment can identify areas where energy is consumed. Property managers and building engineers use this data to create and implement energy reduction programs to save electricity and money.

Energy efficiency is the first step in achieving sustainability in buildings and helps to control increasing energy costs while reducing their environmental footprint. “If you don’t measure it, you can’t manage it”.

Quadlogic submeters log usage (kWh) at hourly and daily intervals so usage patterns can be analyzed.

3. Going Green

Submetering enables building owners to implement an effective green strategy. Hardware and software system are introduced, specifically addressing the needs of the sustainability market by providing functionality that helps analyze residents’ energy consumption habits.

As the industry continues to evolve, the need for a powerful, accurate, and environmentally conscious solution becomes more apparent.
