The Life Cycle Oriented Concepts of Zero Energy Solar House: A Review of SDE2010 Projects

Abstract:

The Solar Decathlon Competition on zero energy solar house was held in Europe in 2010 (SDE2010, Madrid). Sustainability is added as a major contest with special emphasis on reducing long term environmental impacts and costs. The life cycle oriented concepts of the entry projects are reviewed and analyzed. First, to avoid the increase of embodied energy due to extreme pursue for PV productivity, smart combination of technical solutions was stressed, including passive strategies, local and natural materials, and improving the efficiency of the solar system with innovative design. Second, modular design is an important way to improve spatial adaptability, the recycling of building components and the reduction of cost and impacts for transportation and construction. Finally, quantitative LCA & LCC methods to optimize and evaluate the projects were introduced. A comparative study shows that there is a trade-off between the initial and long term impacts, and between the impacts and the costs.
