The Hunter Mechanical & Controls building is at the forefront of technological advancement in mechanical systems and automation. There is no other commercial facility like it in Oklahoma City, or surrounding cities. Touring the location, the level of knowledge and expertise at the foundation of the company is evident. The amount of energy efficiency gained through each system installed in the building is a model for the industry.
At the core of the building’s inner workings is the geothermal HVAC system. Through a simple, all electric, two-pipe fluid distribution system with low pressure ductwork, heat is transferred into the ground during the summer and removed during the winter, efficiently heating and cooling the entire facility with much lower operating costs. The variable frequency compressors used in the system also contribute to energy savings, allowing for more close control.
At the base of the building’s structure is the radiant flooring system. Flexible, durable tubing beneath the floors circulates warm water, evenly distributing air throughout the facility. With no motor or fan, dust and noise reduction is noticeable onsite. It’s an efficient, maintenance-free technology that also contributes to energy savings, significantly reducing the heating bill. Both of these systems also translate into reduced mechanical room space with easy designs and less equipment.
The integrated automation controls from EarthSmart Controls tie it all together, essentially running the facility with little individual involvement. The geothermal HVAC and radiant flooring systems are automated, but also integrated to give information and feedback so settings will be adjusted accordingly. In this case, the automated system looks at the weather forecast, the thermostat, and water availability to determine temperature control, making sure it doesn’t hit dew point. The power monitor for energy consumption also alters the automated system based on time, demand and use.
Highlighting the energy efficiency and cost savings of these technologies is the monthly energy bill at the Hunter headquarters. On average, the utility bill for a commercial building can be estimated at $.50 per square foot. In a 10,000 square foot facility like Hunter’s, the monthly energy bill could easily reach $4,000-$5,000, but they are seeing an over 80% decrease in monthly energy bill, paying only $.07 per square foot. The cost savings are clear, but the environmental benefits from reduced consumption and emissions, along with its automated efficiency, make the Hunter building a state-of-the-art facility.
