GROWING GREEN
The growing green mobile greenhouse was an excellent opportunity to enhance the existing idea of food production. The Center for urban ecology at Butler University funds a small urban farm pilot program for a more extensive system of farming that, in the future, could supplement fruits and vegetables for the College of Butler food distribution system on campus. The Center for Urban Ecology farm (CUE Farm) was limited to crop size and seeding preparation due to ill-efficient facilities. The next logical step in Cue Farm's evolution was to look for such a facility that could meet their needs. Ball State University and its reputation for an exceptional architecture program were given the opportunity to take on this endeavor, and so Growing Green hit the ground running.
Green House Assembly
The Growing Green mobile green house utilized a hybrid of different materials and exterior wall assemblies. The steel structure was constrained to the dimensions of the local powder coating oven resulting in a modulated 3 price structure. The selection of durable materials like; Polycarbonate, fiberglass and Cedar made up the exterior wall assemblies.
Solar Optimization
The southern fenestration is angled by 10 degrees to increase solar exposure for each planter. The client was looking to start planting in late march in order advance crop yields. Solar initialization was temperature control were very important pieces of the project.
Ventilation
Passive ventilation was designed using two large windows on the south facade and four smaller windows on the north facade to create a stacked effect. The windows were controlled using a gas piston which automatically opened based upon internal temperature and humidity levels. Smaller electric fans were used to circulated airflow and micronutrients.
Irrigation
The irrigation system utilizes a digital control box which allows the user ultimate flexibility. The irrigation system was divided into multiple zones for different crops and is set to a timer so the client does not need to be present to watering. Additionally each water nozzle allows for multiple water setting from mist - soak.
