Level 1 Energy Audit

Energy Efficiency Rating ChartWe perform energy audits for most of our customers. It gives us information about energy usage,  savings, and the potential for rebates and incentives. Our audits begin with a Level 1 Energy Audit/Pre-Audit. The pre-audit Identifies the potential for improvement and conceptual approaches for closing the gap from a low performing building to a high performance building.

Step 1: Survey and evaluates the energy usage in a building through:

  • Talking to occupants and building managers
  • Collect drawings and building information
  • Collect All Utility Bills – Minimum of one year
  • Equipment
    • HVAC, Controls, Data Loggers and Flow/BTU Meters
  • Usage/hours of operation and Occupancy

Step 2: Preliminary Analysis

  • Review large energy uses
  • Compare to standard database the dollar per square foot energy use
  • Comparison to other Like facilities
  • Benchmarking (Energy star and ASHRAE)
  • Analyze heating and cooling practices and identify inefficiencies
  • Identify possible cost saving measures and energy saving opportunities

Sep 3: Initial Planning and Ideas for a Capital Improvement

  • Identify opportunities with best ROI
  • Plan equipment replacement with High Efficiency options
  • Demand limiting EMS system that also tacks and monitors energy such as lighting, process or HVAC loads.
  • Identify large and fast payback opportunities (1-5 yrs)
  • Identify longer term payback opportunities
  • Identify possible rebate and incentive opportunities

Step 4: Discuss Common Potential Upgrades:

  • Energy Management Systems
  • Cogeneration System
  • Gas fired chiller for HVAC and ice making equipment.
  • Separate Suite HVAC from main chiller plant.
  • Economizers for central heating plant
  • Use cogeneration or separate generation system to handle peak demands
  • Improve heat recover opportunities
  • Maximize the use of the desiccant dehumidifiers.


  • What makes sense
  • Agree on direction or plan
  • Move on to more detailed analysis
  • Computer Energy Modeling of Building
  • Level II Energy Audit
  • Prioritize solutions and energy saving measures

Long Wharf Theatre Project Wins Award for “Excellence In Construction”

photoThe Long Wharf Theater Main Stage project has been recognized for an “Excellence In Construction Award” by Associated Builders and Contractors, Inc.
The Long Wharf Theater received over $24,000 in utility incentives from CL&P for being more efficient than required by code. Controlled Air, Inc. provided them with economical solution through custom design build, saving them well over $1mil from their original budget. Seven roof top units were installed: Three AAON single VAV variable speed units and four efficient Johnson Controls units. The RTU’s were connected to a CO2 detection system that allows them to limit the outside air intake to only what is necessary, saving money and energy. Noise was also a concern for our customer and as such, we worked directly with acoustical engineers to ensure that the air distribution system and equipment ran with the lowest level of noise possible.
Controlled Air, Inc. will be part of the team presented with the “Excellence In Construction Award” at a ceremony held on January 30, 2014.

Rebates & Incentives

Don’t forget that there are multiple rebates and incentives available to help pay for energy efficient upgrades.

  • CPACE – Low Interest loans paid back through the property tax bill. We have many customers who are finding this a great way to help finance upgrades!
  • CHP – The Clean Energy Finance and Investment Authority (CEFIA) seeks proposals for grants, loans, loan enhancements or power purchase incentives to help finance the cost of combined heat and power equipment for energy-generating projects.
  • LREC/ZREC – This LREC/ZREC program is a bidding process for projects to compete to obtain a 15-year revenue stream from the sale of RECs (Renewable Generation Credit) to the electric utilities.

New Deadly Trend Among Teens

R22_RefrigerantThere is a new trend among teens with deadly consequence, freon huffing. Huffing is the inhalation of chemicals, paint or gasoline through the nose or mouth. It is also referred to as sniffing, dusting or bagging. Freon huffing rapidly destroys brain cells and can lead to heart-failure, brain damage or death. It gives teens the feeling of being intensely drunk but quickly dissipates making detection difficult. Some teens even place a plastic bag over their head with the freon inside which can lead to suffocation.

Here are some statistics about huffing:

  • The National Institute on Drug Abuse reports that one in five American teens have used Inhalants to get high.
  • According to Stephen J. Pasierb, President and CEO of The Partnership for Drug-Free America, 22% of 6th and 8th graders admitted abusing inhalants and only 3% of parents think their child has ever abused inhalants.
  • An analysis of 144 Texas death certificates by the Texas Commission on Alcohol and Drug Abuse involving misuse of inhalants found that the most frequently mentioned inhalant (35%) was Freon (51 deaths).  Of the Freon deaths, 42 percent were students or youth with a mean age of 16.4 years.
  • National Institute on Drug Abuse’s ‘Monitoring the Future’ study reveals that inhalant abuse among 8th graders is up 7.7% since 2002.
  • 55% of deaths linked to inhalant abuse are caused by “Sudden Sniffing Death Syndrome.”  SSDS can occur on the first use or any use.  The Inhalant causes the heart to beat rapidly and erratically, resulting in cardiac arrest.
  • 22% of inhalant abusers who died of SSDS had no history of previous inhalant abuse. In other words, they were first-time user.
  • “Huffing,” or inhaling volatile substances is becoming increasingly popular among children, especially among 12- to 14-year-olds (Archives of Pediatric and Adolescent Medicine, 1998;152(8):781–786).

To be proactive make sure to secure refrigerant, installing locking caps on an A/C unit is one possibility. There is a provision for securing refrigerant access ports on new construction  codified by the International Code Council (ICC) in the 2009 International Mechanical Code (IMC) and the 2009 International Residential Code (IRC) and has been accepted by the International Association of Plumbing and Mechanical Officials (IAPMO) for inclusion in the 2012 Uniform Mechanical Code (UMC), but these codes are not adopted by all jurisdictions.

Please be aware and take precautions about this tragic new trend with teens. It is important for us all to educate preteens and teens about the dangers of huffing. For more information visit UPROARORG.ORG or INHALANT ABUSE PREVENTION

CEFIA Releases RFP for Cogeneration (CHP) Pilot Program

Tecogen Cogeneration

Tecogen Cogeneration

CEFIA is charged with administering a three-year $6 million dollar pilot program. The total funding remaining in the program for all selected projects under this competitive solicitation is $5 million dollars. This program will offer support for projects that are below five megawatts.

However, funding will not exceed the equivalent of $450 per kilowatt of nameplate rated capacity. Financial support is intended to help you achieve a fair and reasonable payback and return on investment during the life of the project compared to purchasing the equivalent amount of power, fuel oil and/or gas from your utility. If you are interesting in installing cogeneration, this funding will offer incentives that will help pay for the installation.

The Children’s Community School

Controlled Air, Inc. partnered with Alexion Pharmaceuticals, through their community outreach program, to install a security system at the Children’s Community School in Waterbury. The school was concerned with safety of their students, they had an on-going struggle with security issues happening both during and after school hours.

We installed a Johnson Controls card access system in conjunction with 16 cameras, DVR, and internet and phone access.

The system has already helped to apprehend individuals speeding through the school parking lot during school hours narrowly missing students. It has also helped to identify those involved in disagreements amongst groups of students.

During the installation process a kindergartner noticed our service technician, Rich Messner, up on the roof working. The student asked his teacher if Rich was Bob the Builder.  The teacher replied, “Maybe you should ask.”  The student waited patiently until Rich came down from the roof then shyly approached him and asked, “Are you Bob the Builder?”  Rich replied, “Yes, I am.” The student was very excited to have met one of his idols in person.

More than 20% of the project cost was donated by us at Controlled Air, Inc.

Gas Conversions

Governor Malloy’s $7 bil expansion of natural gas has made converting to natural gas a possibility for many homes and businesses. Currently there are no incentives to make the conversion, BUT there are incentives and rebates available for the equipment that will run on natural gas. Depending on your current oil or propane usage payback can be as little as 2 years.

  • Most natural gas furnaces and boilers are up to 96 percent efficient.
  • Natural gas produces fewer emissions of sulfur, carbon, and nitrogen than oil, and it leaves almost no ash particles after burning.
  • Natural gas costs less than heating oil and requires less maintenance.

Update on R-22 Refrigerant

R22_RefrigerantThe EPA has finally signed the 2012-2014 (yes a little late since it is already 2013) allocation rule for R-22, which dictates how much can be imported and produced.

Here are the figures:
2012  55 mil lbs, 38% reduction
2013  63 mil lbs, 21% reduction
2014  50 mil lbs, 18% reduction

The amounts allocated are higher then originally dictated in 2009, but the price for R-22 continues to rise. One of our suppliers for refrigerant told us there is no shortage of R-22, only that people are holding on to it to drive up the price! Unfortunately as it gets closer to 2020 when R-22 is to be phased out the price will continue to climb.

The EPA will will now begin drafting the 2015-2019 allocations from 50 millions pounds to 0 pounds in 2020.

If you are running old or outdated equipment it is a good time to start planning to replace the equipment with new energy efficient models that use refrigerant other than R-22. With the rebates and incentives available and the money saved on energy it will help make the new equipment more afforable.

Energy Efficiency Funding

This is just a quick summary of some funding available in energy efficiency for both large scale and small scale projects:


Connecticut Property Assessed Clean Energy (C-PACE) is an innovative program that is helping commercial, industrial and multi-family property owners access affordable, long-term financing for smart energy upgrades to their buildings.

C-PACE allows building owners to finance qualifying energy efficiency and clean energy improvements through placing a voluntary assessment on their property tax bill. Property owners pay for the improvements over time through this additional charge on their property tax bill and the repayment obligation transfers automatically to the next owner if the property is sold. Similar to a sewer tax assessment, capital provided under the C-PACE program is secured by a lien on the property, so low-interest capital can be raised from the private sector with no government financing required.
