O'HARA NATURE CENTER
Irvington, New York
Given the limited budget, the project focused on passive approaches to lighting, heating, cooling, ventilation and stormwater. The southern facade of the meeting room is mostly glass providing for ample daylight. In the summer the deep roof overhang shades the glass and limits internal heat gain. By opening the low windows and the north facade and the high windows on the south facade a convective cycle is set up providing passive ventilation. In the winter, the low sun angle allows for solar heat to be collected by the mass of the concrete floor slab. Stormwater is collected and treated in a series of rain gardens.
