COAC Construction Team Featured On Cover of ACHR News

ACRH News CovershotThe HVAC Industry’s largest publication, ACHR the NEWS, featured a COAC Construction Team image on the cover of the July 4th edition. The picture shows the COAC team lowering a specialty HVAC unit down through the roof to the floor of an expanding data center. This was a very unique challenge due to the difficult circumstances but the COAC came up with a workable and creative solution to getting the job done. Thanks to Greg Meyers of Emerson for including us in the article formation.

New Video: Caltrans Fan Wall Installation Time Lapse

Over the Memorial Day Weekend, the Cooper Oates Air Conditioning Construction Team demolished an enormous (12 ft. x 15 ft., 107,000 CFM) circulation fan and installed a Fan Wall at the Caltrans Headquarters building in downtown Sacramento. The Fan Wall consisted of fifteen individual, 300 lb., fan cubes that provide much needed redundancy and significant energy savings.

NO downtime was allowed for this project which was a critical infrastructure upgrade for an aging, essential services building with over 1,400 employees.

The project began right at 5:00pm on Friday of the Memorial Day Weekend and was fully installed and ready for tenants by Monday at 3:00pm.

Cal Trans Building New Fan Wall Completed over the Memorial Day Holiday Weekend

The COAC Installation Team just completed a challenging, time-crunched project at the Cal Trans Building across from the State Capitol. The project entailed de-constructing and dismantling an enormous single 12 ft by 12 ft. 100,000 CFM / 60 horsepower circulation fan and replacing it with a more energy efficient and significantly more manageable fan wall. The fan wall was made up of 15 integrated, independently controllable Hunt Air fan cubes that generate as much or more than the required 100,000+ CFM of air flow. The final size of the cube array, not including the supporting steel superstructure, was 16.25 ft. wide by 11 ft. tall. The entire disassemble, removal, preparation of new opening, and installation of the 15 cubes was completed in just under 70 hours during the long Memorial Day weekend with no work disruption to the Cal Trans tenants. All of the month’s long planning, creative solutions and great teamwork certainly paid off. Well done team!

Stay Tuned for the Time lapse video of the deconstruction and installation of the fan wall.

SMUD’s energy-saving guru, Bruce Baccei, discusses ideas for saving energy with your roof-top HVAC units

Add-on Variable Speed Controls for RTUs

DCV, mechanical contractor
In a recent article published at the EnergyCentral website, Bruce Baccei of SMUD’s Energy R&D, discusses a topic that he has devoted years of his professional life to, HVAC efficiency.  In particular Bruce reviews the results of a Sacramento field test on a technology that averaged an energy savings of over 39%.

The addition of variable speed controllers to existing single speed HVAC units has proven to dramatically reduce energy consumption and the technology has other significant benefits. Products like Catalyst, also provide the value of fault detection, measurement of energy savings, adjustment of controls, email alerts, viewing performance and Demand Response all by way of the internet. Read Bruce’s article here.

For more information or an on-site survey showing how Variable Speed Controls, like those discussed in the article, can save your energy dollars contact COAC’s John McAlpine.

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.
