Purpose: The purpose of this study was to investigate what measures the Nordic building company JM AB are using or plan to use to get points in the criterion, of the nordic eco-labeling company Svanen, that they call “Gröna Grepp”. The criterion “Gröna Grepp” aims to implement measures that benefit ecosystems, social sustainability, and energy efficiency. Methods: Three methods were used to complete the study. A literature study was used for searching facts about the subject and support why these measures are important. An interview study was made with the project managers at JM to investigate which points in the criterion they had taken or was planning to take. A survey was also performed with the general public to investigate their views of the measures in the criterion. Results: The study resulted in that 41 % of the investigated projects at JM are using their basic license which consists of solutions such as that 10% of the parking spaces must be adapted to be able to charge an electric car and at least 50% of the bicycle spaces are placed under a roof. The survey indicated that people in society were most interested in being able to charge electric cars and in being able to measure their energy consumption. But other aspects were also discovered from the survey and presented in the results. Conclusions: The conclusion is that the criterion Gröna grepp contributes in a positive way to several aspects. And that one should therefore invest more in Gröna grepp in the future. Taken together, one should invest more in implementing ecosystems and greenery in cities through well-planned gardens or growing boxes.

Between year 1961 and 1975 were about one million homes produced, which today is called the million programme. These homes are now in a great need of renovation as they contain hazardous substances in the materials, unnecessarily high energy use and they are in critical technical condition. Purpose: of the degree project is to identify how we can become increasingly sustainable in ROT-projects within the million programme areas. The degree projects studies among other things how a renovation will be sustainable, materials and waste impact, about the million programme rebuilding needs and rebuilding needs of low-energy houses in the million programme. The method: The degree project is based on a literature study, a questionnaire study and an interview study. The literature study has been carried out to gain an increased knowledge of how a ROT-project works and facts about the million programme. The survey consisted of questions about what the environmental work looks like in various ROT-projects. Entrepreneurs working on ROT-projects, landlords who manage housing in the million programme and tenants who live in the million programmehave participated in the survey. An interview study has been conducted with various ROT-entrepreneurs and landlords to get an overview of how the work of the million programmehas looked environmentally. The result: The million programme leak large amounts of energy and heat. Older have shown that greenhouse gas emissions and energy use have increased, so the need for renovation is becoming more apparent. Sustainable renovation is needed to reduce the negative environmental impact of greenhouse gas emissions and energy gas. In a construction process does material production have a major impact on the environment. When it comes to material selection and waste management is an important aspect for the environment within a ROT-project. In order to be able to work in an environmentally friendly way, it is necessary to plan in detail about various factors when handling the use of materials. The various factors are inventory, waste sorting, ordering materials in the right dimension, choosing materials with regard to the environment and handling the materials well during the construction process. Conclusion: The million programme homes are energyintesive and require among other things trunk replacement, ventilation replacement, replacement of electrical installations, windows, balconies and facades. In order to renovate the million programme homes good knowledge is required about ay hazardous substances in the materials and what measures are required to make the homes more energy efficient.
