This paper represents a unique collaboration between experts in architecture and engineering from around the globe to evaluate the true potential to reduce CO 2 emissions from buildings. The result of this experiment in remote collaboration between Europe, USA, Japan and China, was a summary that was generated for the Holcim Forum workshop, "Reduce CO 2 - With technology to zero emissions." This covers challenges of reducing emissions from building construction, operation and maintenance while also presenting an array of potential solutions. Here we expand on that work for the benefit of a broader audience. The paper covers the overall problem of building emissions, both direct and indirect. It discusses the often-overlooked impacts of building material use. It also reviews the problems related directly to building CO 2 emissions and energy consumption, as well as new analysis methods for better system design. Finally, many new processes are discussed that have the potential to drastically reduce building CO 2 production to nearly zero. In summary we encourage new perspectives that increase the utilization of new methods and systems, thereby providing examples of technological groundwork that can incite new policy to reduce building CO 2 emissions.
