doas-graph-300x225Ecotope’s teams contributed research and expertise to NEEA’s efforts to move the Washington State Code toward energy efficient solutions for Northwest climates. Using dedicated outdoor air systems in our climate will allow buildings to ventilate without expending unneeded energy on heating and cooling in spring summer and fall when weather conditions are mild. All part of Ecotope’s mission to design buildings for O-F-F:  A building whose systems are off is Operating For Free.
