The 5th floor atrium was redesigned with a high-performance curtain wall and glazing system in order to prevent solar heat gain and glare from the west. This change also allowed Perkins + Will to reshape the structure with minimal impact and provide connections between the floors of the office as well as add an exterior terrace, creating a variety of spaces to support a creative and collaborative atmosphere for office-wide meetings and events.
The basic principle of solar space heating is to maximize the glazing that is perpendicular to the sun's rays. Passive solar design techniques include direct gain, thermal storage wall, sun spaces, convection loops and radiant floors.
Energy Efficient glazing -Solar control glass is a product developed by the glass industry to allow sunlight to pass through a window or façade while radiating away a large degree of the sun's heat, thereby reducing significantly the need for air-conditioning and sometime even eliminates the need for it.
