Steven Killcoyne is a Passivhaus Certified DesignerHaving been committed to sustainability in architecture for many years, Stephen is now one of a small group of American architects certified in Passive House Design, as accredited by the Passivhaus Institut. This international organization has established a rigorous methodology for creating ultra low energy consuming buildings. Energy reduction—an increasingly important consideration in today’s world—is accomplished through the use of highly insulated walls, high performing windows, tight air infiltration control, building orientation and heat-recovery fresh air ventilation systems. With the proper application of these key features, the heating and cooling system of a Passive House building is approximately one tenth the size of a typical system. This approach to design offers continuous fresh filtered air, great thermal comfort, greatly reduced heating and air conditioning costs and a large reduction in the need for fossil fuels. The implementation of the Passive House Standard is widespread in the Europe and is taking hold in the United States. Across the globe, apartment buildings, individual homes, schools and office buildings have all been constructed utilizing this system with great success.
