High Performance Envelope Systems

Smart Glass

High performance windows can substantially reduce heat from the sun and greatly increase window insulation.

Our design uses Heat Mirror® - low-emissivity, coated films suspended inside an insulating glass unit - to achieve exceptional thermal and optical properties. The airspaces created by the suspended the film, filled with a noble gas, further increase the window’s thermal performance. The glazings have a thermal resistance of R-12.5, a solar heat gain coefficient of 0.4, and a visible transmittance of 0.54. High resistance fiberglass frames complete the package.

Passive Solar

With appropriately selected glazing and dimensionally correct shade devices and louvers, passive solar design techniques are applied to both the south and north wings of the full house. In the summer, the awning and shades are designed to block direct exposure to the living room and sunspace. The sunspace is ventilated or opened up to the courtyard. In the winter, full solar gains help heat the mass within the home during the day and reduce heating loads through the night.

Building Integrated Overhangs

Passive design strategies seek to design overhangs or louvers that admit solar energy in the winter and shade the solar energy in the summer. By placing the window pane inboard of the custom jamb-sill assembly, the window header acts as the shade, without the use of an overhang or awning. The optimal depth is dictated by the location latitude.

Architecturally Integrated Louvers

Tall windows require greater depth of overhang to shade the windows in summer months. Site specific angles designed into artful, exterior louver retain visibility from the interior and block the summer sun from the entire vertical height of the wall.
