Areas of Focus
Ground Coupled Air Conditioning System
Solar and Wind Power
Biogas
Biodiesel
Ground Coupled A/C
Use ground coupled A/C instead of air-air A/C System
Use of the ground as a heat sink or heat source
Reduction of energy usage
Solar Heating, Electricity and Wind
Currently, 500 square feet of solar cells producing 1000kwh a month on Olin
Wind turbine on Roberts for data
Solar trailer outside of Link building can power a small scooter or PC
Solar Electricity
4.7 Hours of sunlight on average in Florida
Estimated 300,000 square feet of useable roof area
Potential of 600,000kwh a month
Wind
Mostly capturing a sea breeze
Turbines need to be elevated
Wind must be blowing at least 6 mph to spin
Only two practical buildings would be Roberts and Crawford
Solar Heating
Solar collectors used to capture solar radiation and transfer it to water
Large insulated tanks used to store warmed water
Can be used with traditional heating methods
Biogas ProductionBiodigestor systems use natural bacteria to breakdown organic material. The gas produced is very similar to natural gas and can be used in the same applications. Theoretically any organic material will break down in a digester system. Many systems use
animal manures as a feedstock, but food waste has significant potential.
The byproduct of the digestion process is a slurry that can
be used as an excellent soil additive.
Biogas Production at Florida TechFlorida Tech’s food service prepares approximately 4000 meals a day and produces at least 300 pounds of food waste daily. A biogas system on campus could produce 16 therms, or 1600 ft3 of biogas, very close to the gas requirements of the Sub cafeteria. If biogas could be used to replace natural gas at just the Student Union, the school would save over $12,000 annually.
Gas Consumption Spreadsheet. Florida Tech Facilities. Personal Communication from Cheryl Smith received 10 Apr 07.
Biodiesel
Cleaner and less harmful to everyone
Works just like regular diesel fuel
Using waste cooking oil ~ 900 gallons of biodiesel could be made each semester
~4,500gals of mixed fuel (20% biodiesel)
Prebuilt systems start at $7,000
Potential to join research into biodiesel

Energy ConsumptionDining services at Florida Tech: $276,350.33
Evans Hall and the SUB café
Every month ranges from $9,000 to $17,000The most amount of money is spent during September
($17,310.56 for Evans and $15, 127.07 for the SUB)No data for RAT nor Clemente’s Center Court
Evans dining hall spends an average of $2000 more per month when compared to the SUBMost of the energy costs come from heating/cooling, appliances, and lighting
AppliancesProducts marked with ENERGY STAR have met the strict energy efficiency guidelines set by the US EPARefrigerators
Use 40% less energy than the conventional models
DishwashersUse at least 41% less energy than the federal minimum standard for energy consumption
LightingENERGY STAR qualified CFL’s use at least 2/3 less energy than standard incandescent bulbs Generate 70% less heat
On-Campus HousingFlorida Institute of Technology requires all incoming freshman (under 24 credit hours) to live in housing located on-campus. After this initial year, students are given an option to live on campus in one of the residence halls or apartment style buildings.
Electricity consumption for FY 2007• Total energy consumption cost for buildings on campus
(Evans Hall, Southgate Apartments with Pool, All Dorms, ELS Grissom, and Crane Apartments) that include housing facilities (excluding March and April) was $734,994.59
• Air conditioning/heating– All apartments (Southgate and Columbia Village) have own
climate control in residence. – All residence halls have buildings centrally climate controlled.
On-Campus Housing cont.Efficiency
• Window and door efficiency• Refrigeration, freezer, and stove efficiency• Lighting
Incentives• Energy use • Water use• Air quality
Recommendations• Student awareness of their impact on energy consumption
by putting in a system that quantifies total load per apartment/room.
• Incentives given to students who consume the least energy

Areas of FocusWater conservation, reuse, recycling
Composting
Chemicals, hazardous waste, space
Traditional recycling (aluminum, plastic, glass, paper, plastic bags)
Water Conservation
Fix Existing ProblemsLeaking faucets and plumbing cause major water lossOne leak can drip up to six gallons of water a day or 2190 gallons per year
High-Efficiency, Low-Flow OptionsShower heads and sink faucets give a low-flow option which aerates the water to use less freshwater
High-efficiency washing machines and toilets can save anywhere between ten to thirty gallons, respectively, of freshwater each time they are used

Water ReuseRainwater Collection
Rooftop storage tanks can be easily placed all over campus buildings to collect and pump rainwaterToilets and washing machines can use the rainwaterPolyethylene tanks are best option—lightweight, UV resistant and relatively cheap to manufacture
Greywater TreatmentGreywater is partially polluted water from all household uses excluding toilet water
Primary filtering in domestic greywater treatment systems allows water to be reused in toilets and washing machines
61 percent of all water used in a household can be considered greywater and be recovered
http://www.clemson.edu/scg/sust/project_rainwater.html
Water Recycling
Wetland RecoverySecondary treatment of water after primary filtering naturally removes all diseases and particles in the waterArtificially engineered wetlands and gardens are becoming an important source of water recovery and companies are starting up to create such products around the States
Melbourne Water FacilitiesThe city reclaims water from all source at the MELBOURNE WATER PLANT, approximately 58 percent of the total incoming volumeReclaimed water is used to irrigate at an inexpensive price but is not potableFIT is offered this water at a flat rate of $150 per month for irrigation
CompostingDid You Know That Compost Can... Suppress plant diseases and pests. Reduce or eliminate the need for chemical fertilizers. Promote higher yields of agricultural crops. Facilitate reforestation, wetlands restoration, and habitat
revitalization efforts by amending contaminated, compacted, and marginal soils.
Cost-effectively remediate soils contaminated by hazardous waste. Remove solids, oil, grease, and heavy metals from stormwater
runoff. Capture and destroy 99.6 percent of industrial volatile organic
chemicals (VOC) in contaminated air. Provide cost savings of at least 50 percent over conventional soil,
water, and air pollution remediation technologies, where applicable.
Composting cont’d
Yard wastes account for
nearly a fifth (over 31
million tons) of all garbage
generated in the U. S.
each year, making yard
wastes the second largest
component (by weight) of
the municipal solid waste
stream.
Students at US colleges and universities generate on the order of 3.6 million tons of waste a year, or about 2 percent of the country's total waste stream. Food and food-related items may account for 10 to 20 percent of this waste.
Current State of ChemicalsFlorida Tech does what it needs to when it comes to hazardous wastesSafety department is trying to define the waste streamFuture plan: Stop the problem at the sourceChemistry and Biological Oceanography labs are recovering and reusing chemicals

Ideas to Reduce Chemical WasteSimple laboratory methods such as proper weighing and measuring of chemicals Organization and inventory of all chemicals and materials present in each individual departmentContinue to recycle chemicals in laboratoriesObtain permits to do acid/base neutralization and metals reclamation from dilute wastewaters
Traditional RecyclingExisting Recycling Efforts
Paper collection is done by Alpha Phi Omega.
Plastic bins are set out by Habitat for Humanity.
Some Benefits of RecyclingRecycling one aluminum can requires 95% less energy than creating a new can from raw materials…enough energy to run a television for 3 hours.
The energy saved by recycling 1 plastic bottle will power a computer for 25 minutes.
Recycling one glass bottles creates 20% less air pollution and 50% less water pollution than when a new bottle is made.
Recycling a single run of the Sunday New York Times would save 75,000 trees.
Traditional Recycling cont’d
Other Campus Recycling ProgramsHarvard University
• Website and hotline to guide people in recycling
University of Florida• Formal program began in 1989
University of Minnesota, Morris Campus• Recycle cardboard, plastic, aluminum,
electronics, tin, class, and paper, and even offer a paper shredding service
Potential for Recycling at Florida Tech1900 lbs of paper per month are collected 8 months out of the year.Annual potential recycling estimates
• 364,750 plastic bottle• 47,000 glass bottles• 25,250 aluminum cans• Total – 437,000 items!!!
Traditional Recycling cont’d
The Plastic Bag ProblemA single, central location on campus could serve as a deposit for empty plastic bags.
Plastic bags could then be delivered to the local Wal-Mart for recycling.
SuggestionsHand out water bottles to incoming freshman instead of laundry bags.
Look into the purchasing of biodegradable items.
Use recycled paper at the copy machines.
Use less paper in classrooms. Instead of making copies of handouts, scan them and let students view the PDF files.
CostsThe cost for recycling is $25.00 per month for one 90 gallon bin.A minimum of 25 bins would be necessary.
Conclusion – Reduce, Reuse, Recycle!!
There are ways to minimize the use of materials and creation of waste
Materials are being reused!
There is some recycling at Florida Tech.
The recycling of more items is a definite possibility, and support for a recycling program does exist.
Conclusions
As a first class research institution and an important force in the Melbourne community, Florida Tech should take a far more proactive stance in addressing the school’s environmental impact.
Overall, saving energy reduces cost, reduces the depletion rate of natural resources, and reduces loads at power plants, which ultimately reduces emissions of greenhouse gases from fossil fuel combustion.
By using this opportunity to educate not only students and staff, but the surrounding communities as well, Florida Tech can have a far reaching impact as a model Green Campus.
