Solar Power System Helps Achieve 'Net Zero' Energy Bill
CLIENT: MARKET ONE | LOCATION: DES MOINES, IA
Getting to a "net zero" design for MODUS Engineering's extraordinary new, eco-smart Market One building was a tall order. To find the way, they enlisted the solar power experts at Van Meter Inc. and Stroh Corporation to create a "net zero" metering system -- one of the first in Iowa
Market One, Des Moines, Iowa, broke ground on April 22, 2014. At almost a century old, the address underwent a nearly $17 million renovation. To control energy costs and reduce its carbon footprint, owner MODUS Engineering's goal was to design a building that would produce as much energy as it consumes.
After exhausting efforts to attain their goal by installing high-efficiency mechanical equipment, building materials and building methods, they still needed approximately 250 kilowatts (kW) of energy to achieve their target. Their solution: install a photovoltaic (PV) solar system.
Hampering the project, however, was very limited roof space. “With this limited real-estate, we needed to reconfigure the system several times to make it work,” explained Brad Duggan, Van Meter Renewable Energy Project Manager.
Working closely with the installer, Stroh Corporation, and MODUS Engineering, Van Meter assisted in the design, implementation, pre-construction, start-up and testing of two solar systems that could work within the constraints of a limited installation footprint.
Market One utilizes PV panels throughout the facility and car canopy. This 222 kW PV system consists of 110,280-watt Solar World™ solar modules on the rooftop and 682, 280-watt modules on the carport, totaling 792 high-efficiency modules and 110 Enphase™ micro-inverters.
“Since the completion of the installation on January 30, 2015, this solar installation has been producing an estimated 22,000 kilowatt hours (kWh) of power monthly, enabling the business to produce 100 percent of the electricity it consumes for a 'net zero' energy bill,” noted Duggan. The end result is a highly effective system that saves energy and preserves the environment by keeping approximately 500,000 pounds of carbon per year from being released into the atmosphere.
MODUS Engineering had originally worked with another solar company that was struggling to effectively meet their changing design needs. Van Meter and Stroh Corporation were able to come in like the cavalry, take over and help design a PV system that would meet their goal.
“We had a very tight timeline on this project and I was greatly impressed with the ability of Van Meter and Stroh to go above and beyond to get the job done,” said Faryal Dotani, MODUS Engineering Electrical Engineer. “Every team member played an important role. Van Meter always delivered on schedule, as promised, so the solar system could be installed without delays.”
Working with Van Meter has helped the city lower its energy bill, improve its security and reduce its environmental impact. “We were looking for a way to lower our energy and maintenance costs and LED lights are helping us accomplish this. The cost savings will benefit all,” said City Manager Jim Ferneau. Certainly, there are more LED lighting upgrades in Burlington's future.
“Working with the Van Meter team of solar specialists was a positive experience. They were responsive, pricing was where it needed to be and coordinating delivery of materials was perfect,” said Kelly Reames, Stroh Corporation Project Manager for the PV installation. “They helped make the project run like clockwork.”
