Hitting Homeruns at Raley Field with Pelican T-Stats

Pelican Thermostat in Raley Field Suite with Logo
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.

For more information, watch a live demo or to see if the Pelican System is the right solution for your building, contact COAC’s John McAlpine at 916.381.4611.

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.

 

Demolishing a 12 foot circulation fan at the Cal Trans Building

Cal Trans Massive Circulation Fan with Man LRHere is the before picture of the 12 ft. tall x 14 ft. wide circulation fan that the team from COAC demolished to make way for the new, more redundant and efficient, fan wall.

Stay tuned for the time lapse video of the demolition and installation of the new Cal Trans Fan Wall.

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.

 

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?

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.

COAC’s New Virtual Walk through of the latest NASA project

Watch COAC’s Virtual Walk through video of one of our current NASA projects. The NASA N233 Cooling Tower #2 project is underway and the planning is comprehensive and challenging. COAC’s Principle Engineer Gary Storck and Designer Mike Garcia teamed up to craft this amazing video to show the client how the new cooling tower and pipes would integrate with the existing tower and fit in the existing space.

Using Building Benchmarking As A Tool

Here are 4 ways to use the building benchmarking process more that just a compliance requirement, but a real tool to improve the return on the building investment:

1. How are your buildings doing?
Understand building performance at a building or portfolio level. See performance in simple metrics and benchmark a building against itself, a portfolio, its peers and ENERGY STAR Portfolio Manager®.

2. Are buildings getting better or worse?

Prioritize where to focus attention by watching building energy use and expense move with weather normalization and changes in your building. Spend time finding solutions for those buildings with the greatest needs.

3. Where are the best opportunities for savings?

Implement solutions that will change building performance. Identify low cost operation and maintenance changes, and plan for improvements with a good return on investment.

4. Have past energy improvements paid off? Measure and prove the results. Every investment-large or small-should yield results. Tracking changes and improvements will allow you to build best practices and save more.
