Making an Educated Commitment to Sustainability

I never want a student to have to study to find a way to undo what we did to their planet.” That statement, spoken by George Bernardon, vice president of grounds management for SSC Services for Education, during the company’s 50th anniversary celebration in September 2019, helped strengthen the building services contactor’s commitment to sustainability. SSC, a Knoxville, Tennessee-based company that provides facility management and cleaning for more than 170 educational clients in 27 states, has grown its sustainability program through employee passion, according to Catherine Merritt, director of communications for SSC. “Maybe it is the nature of working in the education environment that fosters a natural desire for betterment or the education environment that draws to it people who already have this innate desire, but we are all better for the culture that empowers our environments to thrive,” she said. From classroom cleaning to groundskeeping and facility maintenance, SSC works with its clients to prioritize tools and techniques that protect human health and the environment. “SSC does not sell environmental sustainability as an add-on or an afterthought,” Merritt said. “Environmental sustainability is a life-long course we find embedded across all of the microcultures within SSC’s accounts, and every step forward one campus makes is shared and integrated into our collective.” Conserve precious resources SSC’s mission is to manage award-winning campus landscapes while preserving the environment. Its grounds management programs are built around protecting local watersheds, reducing reliance on synthetic fertilizers and pesticides, and building a culture of doing the right thing not only for today, but long term. Water conservation is always top of mind in SSC’s facility management operations. Water-use reduction can be as simple as planting native species or as complex as installing a smart irrigation system, said Brandon Haley, SSC’s senior project manager for sustainability and grounds. Available features on smart irrigation systems include weather- and soil-based controls as well as components focused on water application and flow sensors that support automatic leak shutdown with alerts. “And then there is everything in-between: rainwater harvesting, bioswales, xeriscaping, rain gardens,” Haley said. “Our water conservation programs save millions of gallons of water every month while still allowing the landscape to look and perform its best. It is quite common for a well-run water conservation program to save over 30% of outdoor water usage, with opportunities for conservation goals to reach over 50%.” Energy-conserving tactics include switching from gas-operated to battery-operated landscaping equipment. “Electric equipment is rapidly becoming our standard and is less of a sustainability practice, but a part of our normal operations. Electric handhelds are more accessible than ever as we see battery lives extended and the benefits of reduced maintenance and ease of use,” Haley said. “We also have a fleet of electric mowers, each with over seven hours of continuous mowing time. The reduction of noise pollution that goes along with them is amazing.” One simple way to conserve water and energy in facility maintenance is to verify all equipment is operating according to its engineering design specifications, according to David Payne, vice president of facilities and energy services at SSC. “Operating equipment outside its design parameters leads to less efficient operation,” said Payne. “A good example is a water-cooling tower for a chilled water system. Improper operation may not only lead to excessive electrical usage, but excess water waste caused by unnecessary water loss through evaporation and blowdown, as well as other costs associated with transporting the water to the site and chemicals for water treatment.” Payne recommends establishing a preventative maintenance (PM) program that ensures energy systems are properly managed. Facilities also need to continually look for opportunities for energy conservation improvement, such as through the implementation of new technology. Don’t skimp on preventative maintenance Paul Tisch, regional director of operations for building maintenance at SSC, builds on the emphasis of a strong PM program. “Replacing belts in air handler units, properly greasing and checking AMP draw on motors, and replacing air filters before becoming clogged will mitigate wasteful energy consumption,” he said. Maintenance workers under Tisch regularly assess aging equipment, replacing it with more energy-efficient alternatives. This practice includes upgrading lighting systems with less energy-consuming LED lamps. The workers also practice water conservation as part of the PM plan. “Repairing or replacing leaking pump seals, leaking faucets, and running toilets when needed is only the beginning,” Tisch said. Routine inspections of water-consuming systems such as boilers and cooling towers are part of a maintenance plan. Utilizing technology and water treatment chemicals allows a system to minimize water usage in both steam-generating boilers and cooling towers. For instance, adjusting the cycles of chemical concentration has resulted in a more than 20% reduction in cooling towers’ water consumption, according to Tisch. He explained that creating deferred maintenance (DM) initiatives that are focused on conserving energy will result in cost savings that can help fund the project and reduce its budgetary impact for years to come. For instance, in two years, the Jasper County School District in Ridgeland, South Carolina, which includes multiple facilities for pre-K to 12th grade schools, saved more than US$900,000 in electricity and water consumption at its facilities as the result of a DM energy project created to improve the quality of the facilities, followed by a PM plan that will keep the equipment running at optimal efficiencyfor years to come. Payne explained it is standard SSC practice to operate equipment within its designed operational parameters and to execute a strong PM program at all client facilities. “Too many facilities deprioritize PM only to see their corrective maintenance (CM) skyrocket. This misalignment of priorities costs campuses significantly more in the long term, not only financially, but in environmental impact through energy consumption and landfill buildup,” he said. “SSC fully utilizes a CMMS [computerized maintenance management system] to not only schedule and track completion of work, but also to track the equipment performance history over time.” Measure your environmental footprint Schools who are just beginning their sustainability efforts will want to start
