To extract buildings from Digital Elevation Models, we define a point process whose points represent buildings. We then define a density for this point process which is split into two parts, consisting in an ”internal field” that allows us to model the prior knowledge we have on patterns of buildings in urban areas and an ”external field” that makes the point process fit the data. We then use a...

The behavior of the building and real estate sectors is quite important in matters of environmental sustainability. It is reported, for example, that buildings account for approximately 40 percent of the consumption of raw materials and energy. In addition, 55 percent of the wood that is not used for fuel is consumed in construction. Overall, buildings and their associated construction activity...

October 18, 2011 DRAFT: DO NOT CITE OR CIRCULATE Governments often use their considerable purchasing power to promote policy objectives. However, it remains unclear whether or when public procurement preferences can stimulate private markets for innovative products and services.

Latest European Union programs related to energy efficiency underline the need for retrofitting existing buildings, which are responsible for 40% of EU final energy consumption. Although new buildings can be constructed with high performance levels, the majority of the building stock, characterized by a low energy performance, still needs renovation. Thanks to its potential to deliver high ener...

The overarching aim of this study is to investigate the factors behind the relatively slow evolution of the green residential housing market in Sweden. The intention is to examine stated willingness to pay (WTP) for green and low energy apartments, and to explore which factors have a significant effect on stated WTP among apartment owners. A green building was defined as a building certified ac...
