The Rob and Cheryl McEwen Graduate Study & Research Building: York University's new Research and Graduate Building will merge with and link to the existing, award-winning Seymour Schulich Building and will feature extensive outdoor courtyards, green roofs, radiant heating and operable windows with bird-friendly glazing. One of the first buildings in Canada to use the principles of Thermally Active Building Design (TABS), the building will maximize natural ventilation and solar energy harvesting while minimizing unwanted solar heat gain. A 27-metre-tall solar chimney will provide free cooling and ventilation in spring and fall as well as passive solar preheating of mechanical air ventilation in winter. The new building will be targeting LEED Gold Certification."
