Pelican Mesh-network Thermostat at Raley Field Raley Field is a unique and challenging set of buildings and environments. The facilities have the needs of an office building and a hotel, as well as the special needs of a data center and huge heat generating equipment (like an enormous scoreboard). To manage these diverse needs and physically spread out locations, COAC delivered a solution that provides energy savings, full, flexible and immediate controls from anywhere at a very affordable price. The solution was the Pelican Wireless System.

Pelican Mesh Network Graphic The Pelican system automatically creates an advanced mesh network where all the thermostats communicate with each other and the gateway simultaneously. This enables thermostats to be controlled even if they are not directly connected to gateway.

The system allows owners and property managers to access a simple-to-use, dynamic and powerful management platform for their building with full diagnostic and trend data right on any internet enabled device, including their smart phones. This is a user-friendly solution to more enhanced building controls at a relatively budget price.

Easy Trick to Save Energy Dollars with Your HVAC System

dirty and clean coil

Dirty Coil (left), Cleaned Coiled (right)

Coil Cleaning Is a Money Saving No-Brainer.

Its not really a trick just some good maintenance. Out of all the preventative maintenance steps you can take to ensure your building’s HVAC system works at its peak efficiency, having your coils professionally cleaned is one of the easiest and can give you the best return on your investment over time.

Coils are pretty simple by design. They come in a variety of sizes, and the size has been engineered to do its job according to the size of the area you are cooling. Coils consist of numerous small, metal fins that allow air to move across them, transferring heat in the process and allowing the heating or cooling process to occur smoothly.

The problem is air contains contaminants such as cottonwood fuzz, dirt, pollen, dust, grease, mold spores and moisture, which can settle on a coil’s surface and build up, acting as a roadblock to air flow and reducing a unit’s efficiency. When this happens, an air conditioning unit has to work harder to do the same amount of work, thus using more energy – more than 30 percent in some cases, according to experts.

In addition, other components such as the compressor are at risk of breaking down due to the increased stress on the air conditioning equipment. Hot temperatures + no compressor = no cooling = unhappy building occupants = costly repairs. Other factors such as indoor air quality also can be negatively affected due to contaminants like mold and bacteria residing in your coils.

There are numerous coil cleaning products on the market today and a variety of methods to cleaning a coil. While many businesses have maintenance staff that clean coils, it’s never a bad idea to have your coils cleaned professionally by a trusted service partner as a service professional may find other problems that need to be addressed.

Remember, preventive maintenance steps like coil cleaning offer the following benefits to you and your heating and air conditioning equipment:

  • Reduced risk of breakdowns
  • Increased equipment life
  • Better indoor air quality
  • Improved equipment efficiencies & reliability
  • Reliable building tenant comfort

R-22 – Fading Fast

Sara Jackson - Headshot closeup sml

Sara Jackson COAC Customer Service Manager

As HVAC system owners and contractors, we should all be paying attention to the major changes in the refrigeration markets occurring in 2016. As the complete phase-out of R-22 continues, the EPA has declared that in 2016 only 18 million pounds of R-22 can be produced or imported. The 2016 amount is down from 51 million pounds allowed in 2014, and will be decreasing significantly each year until December 31, 2019, when no new or imported R-22 will be permitted in the United States.

The R-22 supply dwindles and the “normal to warmer-than-usual” temperatures, predicted by meteorologists, for this coming summer will assuredly increase the demand. R-22 prices were up 15% in the final quarter of 2015 and are anticipated to reach record levels by the end of 2016. Refrigerant distributors will be subject to allocation limits and supplies will become scarce. The possibilities of imported counterfeit R-22 is a real and likely possibility, therefore purchasers will have to be vigilant in their research and trust who they are buying from.

r-22 Fading AwayAnother notable change will be the end of production of the “dry-shipped” unit (equipment designed to use R-22, yet not containing any refrigerant at the time of sale/shipment). As of the end of February, manufacturers are no longer able to sell this type of equipment. This means all new units will be required to use other types of refrigerants.

The phase-out will force owners of R-22 equipment to replace their systems or transition to an environmentally approved retrofit alternative for their legacy systems. Manufacturers are coming to the table with new refrigerants such as Gentron 422D, Performax LT, and Solstice N40. These next generation products all have different characteristics and performance specifications. When retrofitting with these alternative refrigerants it will be important to note the lubricant choice and its effect on system performance and to recognize the need to replace elastomers, O-rings, and possibly system valves during that retrofit. In this rapidly changing industry, it will behoove the consumer to research the options and regulations and form solid, reliable relationships with well-informed service providers they can trust to do the job right and keep the comfortable air flowing.

Bob Knows: Winter Building Preparations

Robert Plotner Vice President Service Operations

There are many things to consider when preparing for winter operation of any building, but keep in mind these shoulder months offer a huge opportunity for energy saving.

As we approach the heating season, we need to be checking the heating cycles on all the air conditioning equipment, paying particular attention to the operation of the boilers. During the early hours of the morning heating may be needed to take the chill off but in the afternoon there may be a need for cooling.  A well-tuned building will only use the amount of heating and cooling needed to make the building comfortable.  Too often we find a building is overheating and overcooling and sometimes heating and cooling at the same time, missing out on a tremendous amount of energy savings.

Besides the HVAC systems, building owners should check and clear all roof drains, remove all roof debris and look for cracks or bubbles in the roofing that may indicate problems.  As a service for our customers, our technicians report any issues they may see while they are on the roof of any building, but a thorough exam should be on your winter prep list.

Don’t wait until you have bigger problems at critical times, now is the time to test and review your systems and insure that energy expenses are minimized and tenant comfort is protected. If you have any questions about your HVAC winter preparations, feel free to contact me directly.

Bob Plotner,
Vice President, Service Operations

 

 

Preparing For a Future Without Any R-22

R-22 bannedThe EPA’s release of the R-22 phaseout schedule has provided a better idea of how fast R-22 refrigerant will be eliminated. Building owners and managers can now plan for it over the next few years. A big part of that preparation is education.

R-22 will be gone soon so now is the time to make decisions about your HVAC equipment. In Sacramento, 70-80% of commercial buildings still have R-22 systems in operation. Whats your plan?

3 Ways to Improve Winter IAQ & Productivity

Winter IAQ solutionsAccording to some World Health Organization experts, 30% of commercial buildings in the U.S. have poor IAQ, which is linked to respiratory illnesses and allergies. In addition to shouldering the medical expenses of sick workers, U.S. businesses experience as much as a 33% drop in worker productivity due to poor IAQ. But there are ways to decrease airborne disease transmission and have a healthier building. Read More Here

 

 

HVAC Retirement – To plan or not to plan

The end is coming! The question is, is it better to plan for HVAC replacement or endure the disruption when it occurs.

Old HVAC Ready for Retirement Replacing or upgrading an HVAC unit is never an easy decision, unless that decision has already been made for you due to the unit failing. Many building owners and managers are reactive when it comes to their HVAC systems. Something changes (no air, no cool, no warm etc…) then action is taken to correct the failure or replace the unrepairable unit. Even with diligent and meticulous maintenance HVAC has a finite lifespan and it will fail eventually. The real decision with managing the HVAC assets is will you manage them or will they manage you.

We suggest that you take control and manage these remarkable and quite vital assets. Whether the units are old and running on borrowed time due to the increasing shortage of R-22 refrigerant, you are looking to increase the buildings value and marketability or just want to save energy, taking control will pay off in many ways. Have a plan in place that allows you to be pro-active about your replacement strategy and that fits you budget. Thinking strategically about your HVAC assets is proving to be more economical over the long run than reacting to emergencies.

COAC can provide you with information and expert advice that will guide you through your decision process. Detailed unit evaluations, pre & post energy use modeling, maintenance and replacement planning and financing are just some of the ways we can assist you in taking control. To plan or not to plan, it’s up to you.
