Energy Modeling

 

Energy Modeling, short for Building Energy Modeling (BEM), is the computer simulation of a building used to determine or estimate building energy usage.  BEM is a versatile, multi-purpose tool that is used in new building and retrofit design, code compliance, green certification, qualification for tax credits and utility incentives, and real-time building control.  BEM is also used in large-scale analysis to develop building energy efficiency codes and inform policy decisions.

 

How does it work?

A virtual building is created in a software package, the building components are entered, and the building is simulated over the duration of the one year using a weather file.

This allows for multiple scenarios to balance the lowest construction cost with the lowest annual energy cost.  The estimated energy cost of using different windows, walls, roofs and HVAC systems can all be quantified.  This is how we decide for example, if adding wall insulation provides a shorter payback than installing a more efficient boiler or vice versa.

Energy modeling is required for LEED certification.

 

How BEM is used

  • Building Analysis: On prototype models supports the development of energy codes and standards, as well as helps organizations like utilities and local governments plan large scale energy efficiency programs.
  • Building Performance Rating: Can be used to assess the inherence performance of a building while controlling for specific use and operation.  Inherence performance rating is the basis for processes like code compliance, green certifications, and financial incentives.
  • Architectural Design: To design energy efficient buildings, specifically to inform quantitive trade-offs between up-front construction costs and operational energy costs.  In many cases, BEM can reduce both energy costs and up-front construction costs.
  • HVAC Design and Operation: Commercial building HVAC systems can be large and complex, BEM helps mechanical engineers design HVAC systems that meet building thermal loads efficiently.  It also helps design and test control strategies for these systems.

Greener, Greater Building Plan (GGBP)

 

The Greener, Greater Building Plan (GGBP) is a plan implemented by the NYC Department of Buildings (DOB) in 2014, to improve new construction and renovations.  To proactively address energy waste in its existing structures, a problem that had been a difficult task because of the enormous amount of buildings inside of NYC.  After some digging, the city’s square footage is highly concentrated, (in less than two percent of its properties) two percent translates into 15,000 properties over 50,000 square feet, which account for almost half of NYC’s total energy consumption.

After these findings, NYC executed the GGBP, whose objective is energy efficiency in these large existing buildings. Local Laws were put in place as an energy conservation effort that has been industry-transforming, and internationally recognized.  GGBP is designed to ensure that information about energy is provided to decision-makers and that the most cost-effective energy efficiency measures are sought after and maintained.

The GGBP was the most comprehensive set of energy efficiency laws in the U.S., (prior to the NYC’s Climate Mobilization Act) targeting New York City’s largest existing buildings which constitute half its built square footage and 45 percent of citywide energy use.

For these buildings, the policies require an annual benchmarking of energy and water use with public disclosure(Local Law 84 of 2009); an audit and retro-commissioning every ten years(Local Law 87 of 2009); for non-residential spaces, upgrades for lighting to meet the energy code (Local Law 85 of 2009); and the installation of electrical meters or sub-meters for large tenant spaces (Local Law 88 of 2009).

Goal: Reduce GHG Carbon Emissions 30% by 2030.

Bills Within The Act

 

By now almost everyone has an idea about what the Climate Mobilization Act, i.e the Green New Deal entails.  It’s all over the news and social media, but what’s not there is the fine print.  The laws within the Act are precisely the most important pieces of the entire puzzle.  There are several bills or Local Laws in the Green New Deal,that we at The Cotocon Group have carefully put together for you.

 

Local Law 97 of 2019:

Reducing Greenhouse Gas Emissions

Starting in 2024, buildings over 25,000 square feet will be mandated to meet carbon emission limits.  Buildings that exceed their designated Energy Use Intensity (EUI) limits will face steep penalties, depending on their facility.  There are initiations of emission trading systems to be updated by 2021 as well as renewable energy credits (RECs) limited to NYS electric generation for up to 10% of compliance with the emission limit of a building.

 

Local Law 96 of 2019:

Property Assessed Clean Energy (PACE) Voluntary Finance Program

Establishes a Property Assessed Clean Energy Program, i.e PACE.  A sustainable energy loan program which is a voluntary financing mechanism that will provide low-cost, long-term funding for energy efficiency projects. P  PACE will help building owners finance energy efficiency projects that are required by the new legislation in order to mitigate greenhouse gas emissions citywide.

PACE financing will be repaid as an assessment on the property’s regular tax bill and can be used for commercial, nonprofit, and residential properties.

 

Local Law 94/92 of 2019:

Requirement of Green Roofs on NYC Buildings

Requires the inclusion of a green roofing zone in new construction and for buildings undergoing certain major renovations.  This roofing zone must be comprised of a photovoltaic (PV) electricity generating system (Solar Panels) or a green roof.  Buildings with greater than 200 square feet of usable roof space must install a minimum of 4kW PV electricity generating system.  If a building is unable to install a PV electricity generating system, a green roof system must be utilized.

 

The Cotocon Group

Cooling Season

Cooling Season comes quickly and sometimes with no warning, especially in New York.  It can be challenging to control indoor comfort during springtime weather fluctuations.  In this time, it is also important to make sure that building controls are reset to reflect changes in occupancy schedules, temperatures and daylight.

New York City’s cooling season runs from May 26 to September 24, so maintaining these requirements are crucial.  Usage outside of these dates may result in an electrical demand charge for which funding has not been budgeted.  These guidelines and recommendations have been established for the use and maintenance of air-conditioning systems in City buildings.

 

Many factors impact occupant comfort, such as;

  • Temperature
  • Humidity
  • Air Movement
  • Vertical and Horizontal Temperature Differences
  • Temperature Drift
  • Lighting Conditions

 

Whatever the weather conditions, you’ll want to ensure that your building’s systems are in top shape to control these factors as best as possible to keep occupants complaints to a minimum and ensure productivity and facility performance.

The temperatures are warming up, creating less need for heating and more need for cooling.  To ensure that your building’s performance is running safely and efficiently to increase your comfort and save money, follow these spring maintenance tips…

 

Tips on how to stay cool this summer:

  • Maintain healthy Indoor Air Quality (IAQ)
  • Control Moisture
  • Monitor Thermostat Settings
  • Adjust Lighting
  • Test Cooling Systems
  • Check the Building Envelope
  • Change Air Filters

 

2019 NYC Cooling Season Guidelines for building owners and tenants gives an in depth breakdown for occupants and facility managers on the proper requirements and suggestions to help maintain proper cooling temperatures.

What is an Energy Audit?

An energy audit is the process of identification, survey and the analysis of Energy usage in a building. It is done to optimize the energy usage of the system i.e. Keeping the outputs the same while reducing the energy consumption. A successful energy audit results in energy and cost saving while also reducing the overall carbon footprint.

During an energy audit, health and safety are the primary concerns, while reducing energy consumption and maintaining human comfort. An energy audit seeks to prioritize the energy uses according to the most cost effective technique while keeping in mind the comfort levels.

 

Purpose of Energy Audits:

  • Verify that a facility and its systems meet the Code of Federal Regulations (CFR)
  • Enhance building performance by saving energy and reducing operational costs
  • Identify and resolve building system operation, control and maintenance problems
  • Reduce or eliminate occupant complaints and increase tenant satisfaction
  • Improve indoor environmental comfort and quality + Reduce associated liability
  • Document system operations
  • Analyze the Operations & Maintenance (O&M) personnel training needs and provide such training
  • Minimize operational risk and increase asset value
  • Extend equipment life-cycle
  • Ensure the persistence of improvements over the building’s life
  • Address code issues

 

HOME ENERGY AUDITS in New York

A home energy audit is a service where the energy efficiency of a house is evaluated by a person using professional equipment (such as blower doors and infrared cameras), with the aim to suggest the best ways to improve energy efficiency in heating and cooling the home.

A home energy audit is a process of analysis carried out by a professional. A professional with various equipment to suggest the best methods of energy usage.

Various factors, such as the local climate, the number of residents and building orientation are considered before making final suggestions. The equipment that is in place is checked for optimal performance as well as the life of building.

 

The Cotocon Group has energy audit professionals with vast experience. Use of technology such as thermal simulations and the use of experience goes a long way in creating the best audit report.

In New York City, laws like the Local Law 87, require buildings larger than 50,000 sq. ft. to have an energy audit once every 10 years. The Local Law 87 requires a licensed Professional Engineer to oversee the work and The Cotocon Group handles these regularly. Similarly, Local Law 84 states that as of May 1, 2011 all buildings 50,000 square feet and larger must be ENERGY STAR Benchmarked and report their building’s energy & water use. These laws are the results of New York City’s PlaNYC.  o reduce wasted energy used by buildings.  hich are the greatest source of pollution in NYC.

The Cotocon Group can manage Local Law 84 requirements and start saving you money on building operations, making your building more competitive. We have a group of experienced professionals qualified to carry out these tasks.

 

Benefits of Energy Audits

 

 

 

Greater Comfort

Energy Efficient homes are inherently comfortable because of better insulation, better cooling and fixed heating leaks.

Improved Indoor Air Quality

During an energy audit, focus is also given on how the indoor air quality can be increased. The ventilation and Air Conditioning is scrutinized for proper operation.

Greater Building Durability

One of the major aims of an energy audit is to ensure building longevity and durability. Attention is paid to leaks, moisture levels, ventilation and sun-proofing so as to maintain the buildings health.

Higher Resale Value  

With the energy prices increasing all the time, the value of energy efficient buildings always ensures high market value of your house as much as 20%. A little investment now ensures your home is valued higher than its counterparts down the road.

NYC Climate Mobilization Act

What is it?

In NYC on April 18 2019, the Climate Mobilization Act was passed in the hope of reducing the city’s built environments gas emissions 80 percent by 2050.  New York City is calling this the “Green New Deal”, the law will take full effect in 2024.

Climate Emergency: A cascading breakdown of the climate system due to unsustainable extractive economic and social forces, posing an existential risk to humanity and life on earth.

Annual energy and water benchmarking data is required for these buildings in order to assess their usage levels.  The NYC Local Laws such as; Local Law 133, Local Law 84 and Local Law 87 (which had become Pilars throughout the country) have been put in place to audit these levels of usage for the past years.  The NYC Climate Mobilization Act is the aggressive action of passive results to make a change.

For those structures that can’t be brought up to code on schedule, their owners can offset a portion of their emissions by purchasing renewable energy credits.  If an owner still isn’t in compliance, they can be hit with an ongoing fine based on their actual emissions versus the cap.

 

 

How much do NYC buildings waste?

According to the Urban Green Council, NYC produces 50 million tons of carbon dioxide a year, and buildings account for approximately 67 percent of that—meaning buildings over 25,000 square feet produce 35 percent, or about 13 million tons of carbon dioxide, a year.

— That’s a lot.

How do buildings waste energy?

  • Lighting
  • Heating
  • Cooling
  • Inefficient Equipment
  • Leaky envelopes

NYC Local Law 33

Energy Efficiency Grade

Have you seen the NYC Restaurant Letter Grades?  The letter on the front of the restaurants indicating the Sanitation Inspection results?  Almost anyone who has walked around New York City has.  Well, similarly to that score, beginning in 2020, NYC Local Law 33 will take effect.  There will be grades on every building that is on the NYC Covered Buildings List.  These grades will be based on their Energy Efficiency and Water Usage.

An “Energy Efficiency Grade” means (for a covered building), an Energy Efficiency score assigned through the benchmarking process (Local Law 84) in accordance to a NYC grading tool.

 

The Cotocon Group

NYC Local Law 33 of 2020

 

The ENERGY STAR rating that a buildings earns using the United States Environmental Protection Agency, helps compare the building’s energy performance to similar buildings in similar climates.

NYC Buildings (on the Covered Buildings List) required to comply shall receive scores according to the following:

A= If the score is equal to or greater than 85
B= If the score is equal to or greater than 70 but less than 84
C= If the score is equal to or greater than 55 but less than 69
D= If the score is equal to or greater than 1 but less than 54
F= If the owner of such building has not complied, and the owner has had an opportunity to be heard with respect to such non-compliance.

 

Within 30 days after the owner obtains his/her Energy Efficiency Grade, such owner must post the grade and the Energy Efficiency score upon the location near each public entrance to such buildings.  They must do this in a form and manner established by the department.

PSEG LI Rebate Programs provide customers with numerous types of incentives to not only save money but conserve energy.

Long Island Power Authority (LIPA), is a municipal subdivision of the State of New York that oversees PSEG Long Island, the electricity service provider for most of Long Island.  LIPA currently is responsible for the oversight and ownership of the former LILCO electric grid on Long Island.

History: On December 15, 2011, LIPA selected Public Service Enterprise Group of New Jersey, the largest electric utility of that state, to take over management and operation of the electric grid from National Grid, starting in January 2014.  On July 29, 2013 the state legislature passed a law effectively transferring most of LIPA’s operations to PSEG beginning in 2014.  LIPA’s Long Island retail electric system provides electric service to over 1.1 million customers in Nassau and Suffolk counties, and the Rockaway Peninsula in Queens.

In a bid to create a more sustainable future, PSEG LI provides its customers with various types of rebate programs.  If a customer complies with those standards, he/she is given financial incentives.  The rebate programs are meant to encourage energy efficient practices in order to save energy and resources.

Two types of incentive programs are;
1- Residential
2- Commercial

1- Residential Programs:

PSEG Long Island offers a plethora of incentives which help resident customers adopt more energy efficient equipment and appliances. Incentives are available for home energy audits and for purchase and installation of equipment like refrigerators, washers, dryers etc.

The Cool Homes Program provides rebates for both homeowners and contractors for the installation of energy efficient central air conditioning systems and air-source heat pumps.  Customers can from choose from list of specially-trained contractors.  They can also choose any licensed air conditioning contractor to install their preferred system.
As well as, customers may also choose to receive a free programmable thermostat of $300 value.  This would allow PSEG to remotely adjust the electricity use of the central AC.

In-home energy assessment is available through the PSEG’s Home Performance.  They can with ENERGY STAR program (for homes with central A/C) or through Home Performance Direct program (for homes without central A/C). These programs offer home energy audit at no additional cost.
The rebate amounts can be checked out at the PSEG LI website here.

2- Commercial  Programs:

As with the residential buildings, the PSEG Long Island offers a variety of incentives.  Incentives for its non-residential customers to increase the energy efficiency of facilities through the Commercial Efficiency Program. Major renovations of existing buildings and new construction projects are both eligible for this program.

There are several paths to choose from in the program, each one designed to fit the needs of a particular customer.

The Prescriptive Approach offers rebates on a pre-qualified list of energy-efficient equipment including lighting, compressed air, kitchen equipment, variable frequency drives, and HVAC equipment.

The Custom Approach offers funding for more complex energy-saving measures, perhaps measures unique to the building or business, which are not covered under the prescriptive approach.

Energy Assessment program provides free services for facilities to assess their energy demands and analyse energy conservation measures.  Based on the size of the facility the assessment will include 1-2 hour walk-through of a facility.  It will also provide recommendations on any efficiency upgrades and calculations for rebates and paybacks.

**The rebate amounts can be found out here.
