Sustainable Site and Building

1 Sustainable Site and Building Case Study # 3 : Okanagan College Centre of Excellence Sofia Cardoso/ Ben Ferry/ Ray Sayers Okanagan College Centre of Excellence: Building Description Designed to be one of most innovative and advanced sustainable facilities in the world. Follows the standards of the Living Building Challenge, the most rigorous sustainability program on the planet. Located in Penticton, British Columbia, Canada sq ft, one of the largest Competed in Climate Data Penticton, BC

2 Regeneration Based Wells Checklist This checklist was very subjective, but it was more helpful than the LEED one. Considered regenerative design. Even though the building is sustainable, it fails to address some issues: No on site rain water recycling Maintenance No food production Does not use recycled materials LEED checklist With a score of 52 this building is considered a Platinum building

3 The Site: Penticton, BC Campus Green According to the Wells Checklist the site: Always produces wildlife habitat It neither produces rich soil nor destroys it It consumes food It has no rain water retention No on site waste water treatment, it is sent off site and then returned Low vegetation maintenance needed since indigenous species are used Bus Drop off Summary: Sunlight According to the Wells Checklist: It always uses sunlight Use of photovoltaic panels The building is expected to use only 65kWh [234MJ] of energy per square meter per year

4 Summary: Sunlight Shading devices strategically placed High ceilings help the light penetrate deeper into the room Narrow rooms design- no dark corners Summary: Passive Cooling and Heating According to the Wells Checklist: It always uses passive heating It sometimes uses passive cooling Uses mechanical cooling as well as passive cooling strategies Stack ventilation Concrete floors Heated and cooled with an in-floor radiant system Windows feature a green light/red light system that indicates when windows can be opened to maximize cooling

5 Summary: Water Management According to the Wells Checklist: Neither wastes nor collects rain water Rainwater is sent to the local water treatment facility which uses chemical-free treatment Domestic hot water heating is supplemented by the solar panels Summary: Overall Sustainable Features Innovative and efficient composite wood and concrete panels contain the mechanical and electrical infrastructure required to integrate the gymnasium with the building s systems. A photovoltaic array that supplies energy to the building. Vacuum tube solar panels supply the building s hot water needs. Accessible green roof planted with local flora attracts local species. All of the building s mechanical and electrical services are exposed, where possible, to demonstrate the technology used

6 Redesign: Proposal Cisterns to collect rain water and store recycled water from the wetlands Food production is increased due to fruit and vegetable crops Produces more food than it consumes Wetland area to treat waste water, keeps water treatment on site Reduces the amount of energy needed to transport the water out the facility and back in Water can be used to fertilize the crops Produces rich soil Redesign: Proposal Site Plan Possible cistern placement Possible Wetland Area Possible crop area

7 Redesign: Wells Checklist Major Improvements: Clean air Cleans water Stores rainwater Creates rich soil Conclusion: A Step Towards Regeneration Since the building proves to be already sustainable with the wells score of 1050, and the LEED platinum certificate, we were still able to find some issues with the design. Although there was a storm water collection system, it sent most of the water to the local water treatment facility. We thought this may be a good opportunity to collect the grey water into cisterns for the new vegetable garden we designed, along with having wetlands to treat black water. With the changes, it brings the final Wells checklist to 1400, and of course keeps the LEED platinum status.
