This dissertation discusses a number of arguments concerning who should do what in environmental practice. The purpose of this paper is to analyse the problem of sustainable architecture pertinent to housing and the architect’s responsibility. This study attempts to prepare the ground for a normative debate on the assignment of responsibility between governments, local authorities, enterprises and individuals. The creation of low energy ecological housing has become a key component of the drive for sustainable development. The idea of living in harmony with the environment has become an essential goal of the design of homes and neighbourhoods in the third millennium. There are a number of different perspectives on sustainable housing and each is subject to distinct design parameters. More than practically any other building type, housing encompasses technical, social, political and economic issues. Designers and developers face serious obstacles to producing sustainable housing, yet the pressure and opportunities are greater than at any time in the past. More sustainable patterns of housing based upon enhanced environmental and energy performance will need to become mainstream if wide spread sustainable development is to be achieved. Design is the key to unlocking the potential of the new energy and ecological awareness, giving architects greatly expanded roles in the field of environmentally sound housing.
