This presentation addresses the technical feasibility of meeting the Architecture 2030 challenge based on recent analysis, including ASHRAE research on the maximum technical potential for achieving low energy buildings (RP-1651), and the on-site renewable energy production potential for typical climates. ASHRAE and many other societies and governmental organizations have adopted the Architecture 2030 challenge which calls for new buildings to be zero net-energy (ZNE) by the year 2030. This seminar addresses the technical feasibility of meeting this challenge based on
