While Todd Collins didn’t start his career in the building industry, he quickly developed a interest in architecture and building. While looking for ways to develop his growing passion for energy efficient construction he discovered the Passive House method of building. It soon became obvious that while there was a clear method for constructing high performance buildings, the lack of quality building products was a barrier difficult to overcome. Seeing a great opportunity to mesh his working life with his lives passion he formed A&E Building Systems in 2011. In a short period Todd developed a steady client base and has expanded the companies offerings to over a dozen different products and systems. Todd is a member of the Denver Passive House Alliance board and is active in the CGBG and many other affiliated groups. In his spare time he stays active by participating in many outdoor activities and spends quality time with his family.

Mark Attard has been involved in the building industry for the past 25 years. Always looking for opportunities to learn he began exploring advanced building techniques in the early 1990′s. After becoming a LEED AP he quickly discovered Passive House building, igniting his passion to develop more energy efficient building envelopes. Through the Passive House training and local meetings, Mark met Todd and in the fall of 2012 decided to join A&E. Mark is constantly thinking of ways to improve the performance of his home as well as other buildings. Joining A&E helps him continue to evolve as a green building expert while helping others meet their green building goals. Outside of A&E, Mark spends most of his time with his family and tries to ride his bike as often as possible.
