Sustainability FAQ & Tips
Altering our lifestyles to become more environmentally conscious helps to build stronger communities, save money and improve the longevity of our limited resources. But changing your lifestyle to be more sustainable can seem daunting without helpful tips, advice and support.
Below are some answers to frequently asked questions about sustainability on campus, as well as guides, tips and resources to help make your life a little more sustainable.
Sustainability is based on a simple principle: Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment. Therefore, to sustain life on Earth we must use our resources in a manner that allows us to thrive without infringing on the ability of future generations to do the same. This entails acting in a manner that promotes economic vitality, environmental conservation and social equality.

SLU established two sustainability goals in 2014.
The first goal is to reduce energy intensity (BTU/GSF) by 20% by 2020 from the 2013 baseline. The second goal is to reduce potable water consumption (gallons/campus acre) by 20% by 2020 from the 2013 baseline.
LEED, or Leadership in Energy and Environmental Design, is an internationally-recognized green building certification system.
The Doisy Research Center is LEED Certified. The Doisy Research Center is a 230,173 square foot, state-of-the-art research facility equipped with an energy-efficient heating and cooling system and furnished with recycled steel, concrete, carpeting and materials. The facility also includes a green roof, bike racks, showers and locker rooms for employees who ride their bicycles to work.
A green roof has vegetation growing over it to compensate for the landscaping loss that a building causes. Green roofs can help stabilize temperatures inside and outside the building while providing air filtration.
As part of the construction of SLU's Doisy Research Center in 2008, approximately 7,200 square feet of vegetation was installed. This green roof is an extensive system (4") and is planted with five varieties of sedum. These varieties were chosen based on their survivability in a vegetative roof environment.
SLU uses Rain Bird's Maxicom2 Multi-Site Central Controls Systems, which monitors local weather data, including evapotranspiration rates, to determine if irrigation is required and which suspends irrigation while raining. The Maxicom2 system also employs four rain cans to monitor daily rainfall and suspend or cancel irrigation based on predetermined thresholds.
Yes. Single-stream recycling is the method in which the consumer places all recyclables, including glass, plastic, aluminum, paper and cardboard, into a single bin. This eliminates the need to sort the materials making it easier and more user-friendly to recycle.
Many different items can be recycled on campus via single-stream recycling. If you questions, check out this PDF, ask your area custodian, or email greenbilliken@slu.edu.
SLU has been participating in the national Recyclemania competition since 2011. Learn more about the competition and how SLU ranks.
If you need a recycling bin at your desk, ask your area custodian or contact Facilities Services via .
We take recycling very seriously on SLU's campus and want to ensure that every item is accounted for and goes to the correct place.
Typically, custodians use their trash cart/bin to store both recycling and trash waste using two separate liners, blue for recycling and black or clear for landfill waste. It might look like the recycling is going into the same container, but separating these two forms of trash is important to us.
On occasion, food or other non-recyclable items may end up in the recycling containers. This contaminates the whole bin, forcing us to throw all of it into our waste containers. Custodial Services has implemented two separate bins for collection to remove any concern over this process. Custodians also receive training about recycling at SLU and are well-equipped to answer questions about this process.
Yes, you should do a quick rinse, but it doesn't have to be perfect. Just make sure you get rid of the majority of the food, so it doesn't contaminate the rest of the recyclables.
Recycling on campus is a joint effort between several departments within the Division of Facilities Services and the campus community.
Contact us at greenbilliken@slu.edu so we can place new signage on your bin.
Facilities Management currently recycles light bulbs and batteries used on campus. To request recycling of these items, place a

Trash to Treasure, SLU's move-out initiative, uses the resources of the Center for Social Justice, Facilities Management, Grounds Services, Sustainability and Benchmarking and Residence Life to divert unwanted move-out items, many of which are sent to local donation centers.
Trash to Treasure takes place during finals week in the fall and spring semesters. During the fall program, boxes are placed inside most of the residence halls. Donations will gradually be brought to central locations and picked up by local non-profits and charities. For the spring program, tents are set up at strategic locations across campus for donations to be dropped off.

The EcoLogo product certification program is recognized as a Type-I Eco-label by the International Organization for Standardization (ISO), certifying environmental leaders using sustainable products. To receive certification, products are compared to others within specific categories and scientifically tested by relevant criteria throughout their life cycle.
SLU uses Tork漏 (towel, tissue and napkin) paper products certified by EcoLogo鈩� - the "Environmental Choice."
SLU completed the installation of nine solar arrays throughout campus during the summer of 2015. These solar arrays are estimated to divert 191 metric tons of CO2 from the University's current power system.
The University's utility providers also participate in many sustainability practices.
Individual metered building data is provided by local utility providers for those SLU buildings on separate meters. We are in the process of sub-metering additional buildings that have consolidated utility data bundled together under one meter. This will provide the opportunity to collect and analyze the data and make better energy-related decisions.
天美传媒制片厂 uses Metasys for building automation and control. The system has been configured to enable night setbacks as well as unoccupied and local operation of remote buildings. The system is used to turn air handlers and pumps on and off according to the scheduling needs for a particular building or zone within a building.
Building occupancy needs are determined by academic, event, research and administrative users for each building or zone.
The equipment schedules are optimized to prevent unnecessary run-time, which assists in reducing energy consumption.
Dual technology lighting sensors using infrared and ultrasonic detection have been installed and are used to control lighting in classrooms, conference rooms and restrooms. For any room still equipped with a manual light switch, we ask that you turn the light off when you are the last one to leave the room or if you see a room not in use.
LED lighting is being implemented in many lighting projects including, but not limited to: mounted exterior lights, chandeliers, private offices, banquet rooms, track lighting and parking lots. The conversion to LED technology in Busch Student Center alone has reduced energy usage from 44,136 watts to 5,526 watts. Large multipurpose banquet rooms and common areas have been primary targets for LED retrofits. The result is an estimated energy savings of $13,000 per year.
Vending Miser equipment has been installed on vending machines to manage lighting and compressor cooling cycles. The local electric utility supplier, Ameren Missouri, awarded SLU with an incentive rebate of $10,500 for the purchase and installation 105 units installed on refrigerated soda vending machines. This installation is estimated to save $10,229 by reducing energy usage by 157,000 kWh annually.
