Our Affordable Smart Blue Roof (ASBR) system provides climate adaptation, water conservation, and energy efficiency to your building.
Blue Roof Technology
As described in this CBC article, blue roofs are an emerging rainwater harvesting technology that stores stormwater on roofs. Benefits of blue roofs include climate adaptation advantages such as flood prevention and reduced stormwater infrastructure costs, as well as water reuse and energy conservation.
The Affordable Smart Blue Roof (ASBR)
Enviro-Stewards’ innovation of the blue roof is what we call the Affordable Smart Blue Roof (ASBR for short). The first installation of an ASBR was completed on the roof of Enviro-Stewards’ head office in Elmira, Ontario, in June 2021.
Enviro-Stewards’ innovative ASBR provides climate adaptation advantages such as flood prevention and reduced stormwater infrastructure costs, as well as water reuse and energy conservation.
Given the increasing risk of flooding due to climate change and the associated insurance costs, an ASBR stores water on the roof to attenuate stormwater flow to municipal stormwater systems. The smart components of the roof can automatically drain the roof at a certain rate, store a predetermined volume of water, and automatically flush the stored water if required to free up capacity (for example if a significant rainstorm is approaching). The integrated weather station, temperature probes, flow meters, and other components round out the smarts behind the system.
Stored water can be retained on the roof to provide thermal benefits by keeping buildings cooler during hot weather (thus reducing HVAC loading) and be treated and stored in a tank for water reuse. At Enviro-Stewards’ office, collected rainwater is treated (filter and UV) and used in our toilets. In addition to domestic use, in an industrial application collected water could be stored and reused for cleaning applications (an added benefit is rainwater is naturally soft, thus it doesn’t require softening).
The ASBR once again demonstrates our holistic approach to providing cost-effective and practical solutions to environmental challenges.
