renewable energy + sustainability





our expertise
Patrick works with our clients to develop and implement alternative and renewable energy projects. Projects range from the siting and program management of wind farms to design of solar farms, to design of micro-grids and battery systems to provide efficient and reliable power. Patrick’s team of civil, structural, and electrical engineers and dedicated project managers and control specialists work collaboratively with clients to integrate systems that deliver results. Our advantage is understanding the risks involved including permitting, supply-chain, schedule, financial and constructability when developing renewables from concept to operation. Our services include fuel delivery design, substation design, structural design, and design and permitting of temporary and permanent site improvements. Our clients include renewable developers, investor-owned utilities, and private companies. With a focus on safety, quality and lifecycle costs, and a history of on-schedule and on-budget performance, Patrick is proud to be a premier provider of renewable energy and sustainability solutions.

Forest Preserve of DuPage County (FPDDC) | Blackwell Forest Preserve Solar
The Forest Preserve of DuPage County (FPDDC) commissioned Patrick to do a feasibility study to verify the viability of installing rooftop solar on two of their buildings at the Blackwell Forest Preserve. These buildings are referred to as the Facilities Management building and the Fleet Management building. Patrick performed the studies utilizing Helioscope, a commercially available software package, and Patrick developed spreadsheets. Helioscope provided estimated production rates and allowed for the preliminary layout design. Along with this design tool, separate tools were used to help in developing the economic analysis. Patrick also performed a structural analysis of each building to check on the ability of the buildings to support the added load presented by the solar equipment. Based on the analyses of each building, the Facilities building would require extensive structural reinforcing in order to support the solar equipment and deemed not feasible to pursue. The Fleet building was found capable of supporting the solar equipment. The roof area available for the solar array on the Fleet building was only capable of supplying up to 85% of the building’s electrical needs, so it was determined that the addition of carport canopies be included to provide additional roof space for solar panels. Along with the canopies, the FPDDC asked that design include EV charging stations for the use of district owned electric vehicles.
