Globe Cafe Nutri-Lab (Design) (9Mb PDF)
Globe Cafe Nutri-Lab, by Ercan Ornek
This is a very thoughtfully conceived and designed café with very good use of the space’s volume, light, and available rainfall to create a mezzanine for hydroponic gardening.
Omega-Garden circular carousel is an excellent addition to this model and it's very well integrated into the space. A menu could be designed to work around foods that do well in this growing environment.
The use of propane refrigerators and a gas freezer lighten the electricity usage but still use a different power source. In a design that makes so many departures from conventional spaces and appliances, "free" cold, seasonal rooftop food storage and ambient climate shafts would have been a positive addition to this design. In addition, if excess heat were taken from the PV array, it could replace some or all of the propane used for refrigeration in the kitchen.
The rooftop fish farm is a great addition to this design. It's an excellent utilization of food waste, which more and more commonly is repurposed for either composting or livestock feed. Because the yields aren't certain, it's difficult to measure the benefits of using the space for fish, as opposed to more fruit and vegetables. Rooftop greenhouses can be used to grow foods that have high demand but are not grown locally, where as the embodied carbon of fish is relatively low in coastal Washington.
The south wall is also an excellent place for PV. The panels on the east façade, entry canopy, and north slope of the fish farm can be eliminated, as they would be considerably less effective.
Passive solar would have been an excellent addition to this design, especially in conjunction with the PV panels, from which excess heat could be repurposed.
