In modern construction, a thoughtful integration of green building technology can make a tremendous difference in the input and output of the energy consumption of any building.  The Green SEED organization is an environmentally conscious group of professionals committed to the improvement of the building sciences sector.  Our goal at Green SEED is to build, design or develop a more efficient building through:

SUSTAINABLE

ENERGY

ENVELOPE

DESIGN

Windows and doors comprise a large part of the exterior building envelope and from a green building standpoint.  Windows and doors rank second only to the design of the HVAC system in overall complexity.  Sustainable window design maximizes the benefits of day-lighting while minimizing energy use.  It also considers the need for raw materials and life-cycle, maintenance and transportation costs.  Therefore GreenSEED’s primary discipline is window and door efficiency and overall effectiveness.  There are three primary factors in a window and door energy performance model:  ( 1 ) Radiation – the process in which energetic particles or energetic waves travel through a medium or space; ( 2 ) Thermal conduction –  the mode of transfer of energy within and between bodies of matter due to temperature gradient; and ( 3 ) Convection – the concerted and collective movement of ensembles of molecules within fluids.  Frame construction, glass and spacer material that separates the panes of glass are also important factors that determine a window and doors energy performance.
