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.

Game Changing Technology: Transformative Wave’s Catalyst Roof Top RTU Energy Solution

Catalyst RTU Solution by Transformative WaveMore Than A VFD, Transformative Wave’s CATALYST Verified as Powerful New Way to Save Energy with Rooftop HVAC Units.

Most commercial buildings are cooled by packaged rooftop units (RTUs), but RTUs have a problem: Their fans run at full power, even when cooling demands are low. A few years ago, retrofit kits – like Catalyst – hit the market. These kits enabled building operators to upgrade their existing single-zone RTUs to variable-air-volume operation with claimed HVAC savings of 25 to 50 percent.

Originally, these claims were greeted with much skepticism, but independent tests keep bearing out vendor assertions. In 2013, US Dept. of Energy’s Advanced Rooftop Control (ARC) Retrofit: Field-Test Results (PDF) verified savings and demonstrated that these products- especially Transformative Wave’s Catalyst – are ready for prime time.

Game Changing Technology – VRF

VRF: An Energy Slashing HVAC System on the Rise

Variable Refrigerant Flow (VRF) also known as a Variable Refrigerant Volume (VRV) HVAC systems are becoming an important HVAC solution in the U.S. VRF’s make up about 24% of the global commercial air conditioning market and over 35% market share in China, India, and Eastern Europe. USA only represents about 3% of the market, but it is growing rapidly with multiple manufacturers like LG, Daikin, Carrier, Mitsubishi and Sanyo.

A VRF system allows one outdoor condensing unit to be connected to multiple indoor fan-coil units, each individually controllable by its user, while modulating the amount of refrigerant being sent to each evaporator. By operating at varying speeds, VRF units work only at the needed rate allowing for substantial energy savings at partial-load conditions.

VRF systems have some distinct advantages over conventional systems but they are not for every situation or  application. Learn more about this growing and innovative HVAC solution and review case studies at the end of the article.   READ MORE HERE

Editors Note: We are seeing greater demand for this technology due to life-cycle cost benefits and occupant comfort benefits that outweigh the higher first-cost as compared to conventional systems.

Building Operations: The First Place To Look To Improve Energy Performance

Improve building energy performance The enduring fact remains that no matter how good a piece of equipment is, no matter how well a building is designed and no matter how much money is spent, all it takes is one override of the HVAC controls to throw off energy efficiency efforts.      READ MORE
