In fact, North Dakota has the highest energy consumption per capita in residential buildings （101 MM Btu in 2013）, and its energy consumption per capita in commercial buildings ranks the second （l 18 MM Btu in 2013） in the nation. When humans spend a long time indoors to escape the inclement weather, their health will be more susceptible to the indoor environment. In addition, North Dakota has the 3rd least number of green buildings certified by LEED （Leadership in Energy and Environmental Design） in the nation. This paper aims to investigate the status quo of buildings with respect to energy, health and sustainability in North Dakota, and attempts to propose strategies regarding research and higher education to rectify the current issues. These strategies include but not limited to forming the architectural engineering program, a comprehensive and interdisciplinary program in buildings.展开更多

As a result of these debates, both the several levels of government and some of the NGOs （Non-Governmental Organizations） have commissioned innumerous opinion researches aiming at measuring and evaluating the knowledge and perception of the public in relation of the best non-polluting energy sources. Prior to 2001 these researches would not make any sense in Brazil., however due to that year＇s drought, the competent authorities were faced with the necessity of developing a plan, the PNE2030 （Piano Nacional de Energia） aiming, among others objectives, at finalizing the construction of the Angra three plants and implementing new nuclear plants in places still to be determined. Allowing for the complexity of the subject, this paper presents a field research conducted from September 28th, 2010 to October 28th, 2010 assessing the current level of perception of the Brazilian population about the nuclear area, in particular of the residents of three cities of Rio de Janeiro. As a result of this work, the authors suggest how the competent authorities should proceed to reach in an efficient manner a greater understanding of the population about the proposed subject, through communication campaigns being both informative and educational.展开更多
