The ENMAX Conservatory came to life when the Calgary Zoo decided to convert two existing aging green-houses from the 1960's into a new mixed-use facility. Set in the south portion of the Calgary Zoo campus, the new ENMAX Conservatory houses a visitor centre, banquet facilities as well as two revitalized greenhouses. The greenhouses are now experiential learning facilities designed to educate visitors on the relationship between humans and their environment. The focus on ecological education informed design decisions at every stage of the project. The building program extends outside the building through the surrounding Dorothy Harvie Gardens which are a showcase of plant life suited to the Calgary region. The impact of the project on the site and surrounding environment is minimized through the use of native plant species for landscaping, retention and reuse of storm water runoff from the greenhouse roofs for irrigation of indoor plants, and night sky friendly lighting.
