ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level. This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis. The purpose was to study modern green solutions, used in different reference projects to collate and pass on the knowledge and experiences from both production and usage of the solutions, to indemnify the quality of them for energy efficiency. Five green solutions were selected: Green lighting installation Solar shields for facades of glass Heat recovery with MVHR-system Demand controlled systems Wall and terrace solution with insulation of PIR. The different solutions were at first studied theoretically and then, if possible, at the site of the project. Interviews were made with adequate people in the production and the intent with the thesis was to find out experiences of the chosen projects. Since the numbers of eco-certified buildings are increasing, an aim to link the different solutions with certifying systems rose, foremost towards the LEED system (Leadership in Energy and Environmental Design) – in line of Skanska’s environmental initiative. The result from the study of green solutions shows that green thinking and interests of energy efficiency by costumers – of economical or environmental reasons – are increasing. The review also shows the fact of green solutions requires economic investments, but a relatively short payoff time can be earned by reduced costs of energy savings. Trends are affecting how we build, which may not always be at the best from an environmental viewpoint. But the fact is that even if large glass
