15,500,000 brick … Sustainable … A Hundred Plus Year History!


The National Building Museum in Washington, DC (USA) is a showcase example of how the stack effect of masonry units can achieve natural ventilation and infiltration. Originally the Pension Building, the National Building Museum was designed to provide natural air-conditioning and light for its employees. Through the use of windows and air vents in the exterior walls of the building a ventilation system was created where hot air escaped through the skylights in the roof. The upward flow of air through the large central atrium would draw in fresh air through the exterior wall openings. The significance of brick construction cannot be overstated. The thermal lag created by the brick bearing walls helps to keep the interior of the building cool during the hot Washington, DC summers. And, the combination of the thermal lag and stack effect is how the National Building Museum maintained a comfortable interior environment prior to the installation of air conditioning.

These same concepts--Thermal Lag and Stack Effect are two of the six core concepts identified in the 2009 BrickStainable Design Competition entries. Check out all six design techniques utilizing brick to achieve sustainability goals.

Just this fall, Potomac Valley Brick (PVB) represented the brick and masonry industry by participating in the Festival of the Building Arts event hosted at the National Building Museum. PVB’s team partnered with United Masonry, a local mason contractor, to lead the bricklaying demonstration. This event was attended by thousands of visitors of all ages. A good time was had by all. Ellen Jacknain, coordinator of the Festival of the Building Arts noted, “As always, bricklaying was one of our most popular activities. Thank you so much to (Potomac Valley Brick) Dave and all of the workers for their expertise and patience in working with all the young visitors. The event’s general atmosphere of learning and fun was remarkable – due in large part to the enthusiasm of demonstrators like you.”

And we’ll be back at the National Building Museum in March. It will be the venue for the 2nd Annual BrickStainble Awards Celebration for the second year in a row. We can’t wait to return to this fabulous brick structure for another night of sustainability celebration!
