Week 11 post-session activity: reflection of Building a low carbon house- more stars or Life Cycle Design?

This article compares star rating with life cycle design. 0star rating is ' synonymous with a glass box in the desert', 10star rating requires to keep it comfortable without air conditioning. However, to achieve 10 star needs to remove all thermal control impacts, which is still far away from low carbon design outcome. 

LCD provide a method for designers to know all carbon impacts through its lifespan. In addition, LCD consider the function and to minimize carbon footprint. Thus, it's much easier to reduce footprint by making it smaller, having more people live in and enhancing its lifespan. So designers can use LCD to answer the questions Alex have put forward at the beginning of the article. 

I do think life cycle design is a good technology to know carbon footprint, but it still has advantages. For example, a life cycle design is not always a reliable indicator of true carbon footprint, this would lead to mistakes. however, everything has a risk, anyway, I think LCD is useful to help design low carbon building.
