“Doing what was right for the environment was the first goal of this redevelopment project for Berry Architecture & Associates. We wanted to create a pleasant oasis for our staff and our clients where they could be surrounded by a little bit of nature in a downtown urban setting.”

A Little Bit of Nature in a Downtown Urban Setting
Completed in 2011, the Berry Architecture + Downey Roth Hrywkiw Fidek LLP building was a complete revitalization and modernization of a run-down 1950’s bowling alley in downtown Red Deer, Alberta. The green roof, planted in 2012, enhances this downtown neighborhood both aesthetically and environmentally adding a variety of flowering plants and grasses to the area including canada buffalo -berry, prairie onion, wild flax, and wild bergamot.
Students cultivate vegetables and herbs from seed in the greenhouse that are transplanted into raised planting beds. With the help of teachers and parent volunteers the students at P.S. 6 Eco-Center grow fruits, vegetables and herbs for the school cafeteria's salad bar. They collaborate with the cafeteria staff to develop recipes for the produce grown on the roof.
A unique feature of the green roof is the flowing stream which provides habitat and support for birds and insects. Staff and clients enjoy the pleasant setting of this natural retreat through a variety of social events including barbeques and green roof parties, as well as meetings and lunch time gatherings. Three raised planters provide fresh herbs and vegetables for the staff who take turns caring for the gardens. The gardens and stream are watered exclusively through the grey water system. Stormwater is collected in holding tanks located in the mechanical room on the main floor. That stormwater is then used to water the garden planters, refill the stream as needed, and even provide water to on-site toilets. All non-vegetable plants are indigenous species which do not require watering. Since the renovation, the runoff discharge rate and quantity values have decreased by more than 25%.
One goal of the green roof was creating a bio-diverse habitat for wildlife with an emphasis on indigenous pollinators by providing food with a wide range of indigenous plant species, as well as flowing water and perching and nesting sites. Other goals were to decrease the impact of rainwater run-off on the municipal water system and to improve the air quality of the urban environment by installing the roof on a formerly plant-free site.
