Advanced Glazing
The glazing strategy for Dana Hall combines careful proportions, locations, recesses, canopies and topography with advanced technologies. The triple-glazed punched windows on three siddes of the building are tall and set deep in the wall with two low-E coatings to minimize heat gain. Continuous curtainwall glazing at the ground floor is under cover from the floor above. The penthouse is shaded by the photovoltaic canopy.
The new south addition is clad in an advanced all glass facade system designed with passive measures and active controls to produce a thermally efficient envelope responsive to its environment. The glass facade is made of 2" triple-glazed insulated units and high-performance vacuum insulated glass panels arranged in response to orientation and to maintenance of visual connections to the landscape beyond. Both units have integral expanded metal mesh shading and are silicone structurally glazed to a thermally-improved aluminum curtainwall frame. Each component is optimized for thermal performance with a whole system R-value>8, more than four times more efficient than the latest energy code requirement. The system also pairs automated vent windows with daylight-responsive shades to allow simultaneous daylight control and natural ventilation.
