Quick Winter Tips

Taking care of these basic items can help save you money and energy.

  1. Clear off roof hatches of snow and ice. If hatches are not cleared and there is an emergency we will not be able to access the roof.
  2. Clear snow & ice away from heat pumps. Heat pumps can freeze, causing improper functioning.
  3. If you run A/C in the winter due to internal load, be sure:
    • Clear snow & ice away from condensing unit.
    • Make sure your A/C is capable of low ambient operation.
  4. Keeping snow away from equipment electrical panels will help prevent water from entering and possibly causing short circuiting.
  5. Safety with snow & ice is always a concern. Keeping your equipment accessible during the winter time can make it easier for our service technicians to access your equipment safely if repairs are necessary.

Efficient Building Controls

energy-efficient-bcBuilding controls systems are one way to save money and energy on your building. If your system is not set up correctly you could lose energy and money. There are many reasons you system may not function optimally and we will discuss a few of them here.

It is important to make sure that staff does not manually override any of the settingsand that they are trained in reading any errors within the system so that they can react properly.

Monitoring & Evaluation
Another very important part of building controls is evaluation. Once a system is set-up it should be monitored to determine if the building is operating as efficiently as expected. Building controls systems are not a set it and forget it system. You may have expectations that a building will need a certain amount of heating or cooling, but it may actually need more or less.

The building controls system, as well as the equipment connected to it, need proper maintenance. Like all things mechanical,building controls systems require maintenance so that they perform at top efficiency. Maintenance includes calibrating sensors, checking valve actuators, damper actuators and backup information. It is important to make sure all equipment and systems are updated and have the proper service and maintenance.

Improper Set-up
All equipment should be connected to the building controls system. If not, improperly functioning equipment may go unnoticed. This could lead to a decrease in the equipment’s efficiency or a breakdown of the equipment. The building controls system helps to identify smaller issues occurring in the equipment thereby decreasing larger ones. Having more items visible to the building controls system, such as lighting and HVAC has many benefits. Lighting levels within a building can make a very large impact on the energy use and the air conditioning load.

Need Updated Equipment
We often install Facility Explorer supervisory controllers that provide integrated control, supervision and network management services to one or more local networks of field controllers. These controllers also provide system-wide coordination to automate building control operations. All Facility Explorer supervisory controllers provide modular and scalable supervision and control for your building automation system. You choose only those hardware and software features that are applicable to your project requirements. One feature includes the ability to visually see how systems are functioning.

Make sure you are getting the most out of your building management system by using it to its fullest capabilities. The small investment in training, monitoring and maintenance will provide a true cost savings to your company.

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.

Dear Vincent,

On behalf of the U.S. Environmental Protection Agency’s Combined Heat and Power Partnership, I am pleased to provide you with your organization’s 2013 Certificate of Avoided GHG Emissions. The certificate documents the estimated carbon dioxide emissions avoided in 2013 by the CHP projects for which you provided data, expressed in metric tons and the equivalent emissions from electricity use by U.S. homes. This estimate is calculated by comparing the emissions from each CHP system to the total emissions from conventional separate heat and power (i.e., grid electricity and on-site thermal generation).

The certificate also includes the cumulative carbon emissions avoided by the CHP projects you have reported. The certificate can be a valuable resource for communicating the environmental benefits of CHP to your customers, your stakeholders, and the public.

If you have any questions regarding the 2013 Certificate of Avoided GHG Emissions or any of our tools and resources available at www.epa.gov/chp, please do not hesitate to contact the CHP Partnership at (703) 373-8108.

New Deadly Trend Among Teens

99_9_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
