Academy District 20 Green Grant Application Date: April 17, 2011

School Name: Rampart High School

Project Description and Scope: Installation of solar panels to power a sustainable greenhouse

A group of Rampart High School students enrolled in engineering, CADD, and construction classes have worked collaboratively to design a sustainable greenhouse to be installed locally on our campus. The greenhouse is slated to be completed by the end of summer 2011. The intent of our greenhouse project is to engage our students in curriculum and general conversation about topics in sustainable living. These topics were at the forefront throughout the design process, as students researched the importance of smart materials, building location, and architectural design features that allow the building to be “in harmony” with its surroundings. The greenhouse design calls for dimensions that parallel the path of the sun through the sky at our exact latitude in order to capture maximum solar energy on the summer and winter solstice. In fact, every aspect of the greenhouse design, from its geographical orientation and location, materials selection, and physical dimensions, has been implemented with the idea of maximizing energy efficiency. “Gray water” runoff will be collected locally, filtered, and recycled to a central irrigation tank, minimizing water waste. Pending city approval, rain water will be collected locally and diverted to the central irrigation tank as well. The overarching goal with the greenhouse project is to demonstrate the principles involved in “living off the grid,” in this case in regards to cultivation of food and ornamental vegetation. By collecting and recycling water locally, we can reduce our dependence on water utilities. By minimizing our energy use through smart materials and design, we can reduce our dependence on grid-based electricity, and solar power would completely eliminate our usage of grid-based power. Curricular tie-ins include the study of the costs of solar energy versus grid-based electricity, as well as the ecological and economic impact of grid-based power. If the students’ vision of the greenhouse is carried out, the RHS greenhouse will be a model for sustainability, as it will not draw power from the grid, it will recycle water runoff (and potentially collect rain water), and can be used for growing food organically. The greenhouse also provides a location where composted soil may be used, opening the possibility for future projects in recycling. The purpose of this grant application is to procure funding for a small solar panel array to power the greenhouse. Specifically, the energy collected will be used to operate the pumps that power the irrigation and water recycling system, as well as a small electric heater to be operated on days of extreme cold in order to maintain year-round growing conditions. The installation of solar panels will save the school money by eliminating our need for grid electricity to power both current and future educational growing projects.

Projected Cost Savings Approximately $500 - $700 annually

The greenhouse will be used for a variety of educational growing projects that ordinarily would use a substantial amount of electricity for artificial lighting if conducted indoors. AP Environmental Science classes conduct an annual in-depth study of ecology, and currently use multiple 100 watt growing lamps for an average of 10 hours per day for a 6 month period. AP Biology classes conduct a similar growing project as well. In addition, there are several intended uses for the greenhouse that would potentially use a large amount of grid electricity to run irrigation pumps and artificial heating throughout colder growing months. These include raising produce for school “farmers markets” and other small fundraisers, growth of ornamental plants and flowers for use in school clubs and biology classes, and laboratory activities throughout the science department. The greenhouse may also be used to raise low-water ornamental vegetation to be planted across the district in place of ornamental sod.

It is estimated that the aforementioned projects currently or could potentially consume upwards of 7,500 kilowatt hours annually (some of those kilowatt hours are already being used by growing projects, while some are projections based on estimated future greenhouse usage). At an estimated cost of 8 cents per kilowatt hour, this amounts to an annual cost of just over $600.

By using solar energy to power the greenhouse, our school could conservatively save between $500 and $700 annually. This does not account for the possibility of lowering water usage by replacing ornamental sod with vegetation that requires less water, which is a potential future application of the greenhouse.

In summary, it is estimated that the installation of solar panels to power the greenhouse could result in an annual cost savings of at least $500, conservatively. This is accomplished by discontinuing the use of artificial lights for current educational growing projects, and avoiding the use of grid power to operate electric heaters and irrigation pumps to operate the greenhouse.

School in the Woods Greenhouse Green Grant Proposal

Who are we and what do we believe and value? We are the naturalists of School in the Woods and we believe in our mission statement:

The Mission of School in the Woods, dedicated to the study of natural sciences in a natural setting, is to inspire our students to be critical thinkers as they pursue lifelong learning through direct interaction with living systems, integrated into an academically challenging curriculum in a safe environment. Our naturalists will share their deep appreciation and stewardship of the natural world with the larger community.

What we already do for the environment at our school? Some of the things we already do out at School in the Woods are very green, but we still want to improve and make our school even greener. One of the things we do out at school is composting, there is an indoor worm composter and four 55 gallon outdoor drum composters. We also do terra-cycling & single stream recycling. We try to recycle almost all of our waste. We are active gardeners, with both outdoor raised garden beds and some small plants in pots and containers that we have to transport in and out of the building every day so they won’t freeze. Energy conservation is a top priority at School in the Woods. We turn off the lights and use the sunlight coming through the window whenever possible. Also, we keep the thermostat at 50 °F at night and 60 °F during the day. Our sweatshirts, slippers and knit hats keep us comfortable. The hand-knitted hats that we wear are donated by volunteers. School in the Woods has made many steps in the right direction; this grant would help us to further reduce our carbon footprint and create many new learning opportunities.

How will the greenhouse enhance our commitment to our mission and sustainability? This greenhouse would increase our school’s support of our mission by allowing for the direct interaction of living systems throughout their life cycles. It will permit us to put more sustainability into practice by reducing our electrical use and increasing the number of plants we can grow, study, measure, and maintain. In the cold months, we use grow lights round the clock to germinate seeds, keep the plants growing, and fans to strengthen the plants. The proposed greenhouse utilizes solar lights and automatic vents. It is physically demanding having to carry the plants in and out every day, and we could avoid this by keeping the germinated plants in the greenhouse more of the time. A greenhouse would allow us to grow more plants. In the past, we have enjoyed freshly harvested salad with our Friday pizza lunches, and a greenhouse on the property would allow us to harvest greens on a more frequent basis. We lose a lot of moisture due to frequent breezes when our plants are set out on the deck each day. A greenhouse would help reduce our water consumption by reducing water loss due to evaporation. Those are some of the ways a greenhouse can save us energy and improve our school. We advocate for ourselves and advocate for our wonderful mother earth.

Who contributed to this grant proposal, and what have we been doing to create our grant? All the School in the Woods naturalists were involved in coming up with a specific sustainability area to improve in our school. The overwhelming feeling was that we needed to take our botany program to the next level. We then selected a core group of naturalists, parents and faculty. They have been meeting almost every day, and smaller groups have been working at students’ houses too. For the past few weeks we met at school each day during lunch and recess for about 45 minutes. On three of the days we made phone calls to local businesses to get information on pricing, discounts, and accessories for our greenhouse. We worked as a group to put together this grant proposal and do some of the typing. We also photographed students doing their jobs, researched our needs to find the best greenhouse to meet our requirements, and decided how to put our grant proposal together.

Rion Green Giant 8'6" x 16'6" Greenhouse Premium Package

• Overall head room height: 8 ft. • Interior wall height: 6 ft. 9 in., door frame height: 6 ft. 9 in. • Durable resin frame construction allows for snow loads up to 1100 pounds • Translucent light-diffusing 6mm polycarbonate on all four sides and

translucent light-diffusing 4mm polycarbonate on roof • Weatherproofed, UV stabilized safety glazing for roof panels • Double French Doors for easy access and additional ventilation if needed • Push-fit assembly: simply snaps together, no tools or screws needed • Premium package includes - basic greenhouse, 3 roof vents, 3 side louver

vents, 3 automatic vent openers, 3 automatic louver openers, 1 base kit, rain gutters, 5 two tier staging tables and 1 solar light

How we will make sure that our greenhouse is useful each year and doesn’t get run down? We will adjust our job’s schedule to make sure that there are always a sufficient number of gardeners on the job. We will identify parents who will be responsible for the scheduling of our plantings, upkeep, and harvesting. Given School in the Woods tremendous amount of parent support, we are certain we will have parents contributing time to our botany and gardening program. Key parents will be selected, who will assist with the weekly training of student gardeners and ensure that schedules are kept and plants are not neglected. We will investigate ways to prevent the greenhouse from getting below freezing during early fall and mid spring days. Having materials inside the greenhouse that absorb heat (solar mass) during the day is one idea. We may periodically need to carry some plants inside on colder, but having 52 students to carry helps. We have purposefully chosen a greenhouse that is portable should the need to remove it arise.

Funds Requested: greenhouse ($3932 have written quote w/5% discount), gravel to underlay base ($80)
