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

Cal Trans Fan Wall, COAC, Mechanical Contractor

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.

 

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.

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 over-cooling 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 at rplotner@coacair.com or at 916.381.4611.
