Detta är en Uppsats för yrkesexamina på grundnivå från Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik; Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik


The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljöbyggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed. First a literature review was carried out with delimitation to evaluate the systems manuals and guidelines for new produced multi-apartment dwellings in Sweden. Then a comparison between the systems assessments and methods of calculations for the energy field as well as the systems considerations for the energy’s environmental effect was carried out. The comparison was based on emissions related to production and use and also depletion of non- renewable resources. Finally the theory from the literature review and the results from the comparison were discussed and that led to some recommendations for the systems.

Different assessment systems that are used for the systems are grading systems, marking systems and certifications. The systems judge similar indicators and subfields for energy. Something that they all judge is building’s annual energy use but they define them differently. Beyond that, the systems distinguish in the judgements of the energy field. The requirements of the inputs for energy calculations are different for the systems. As well as the energy’s environmental impact, all systems take some consideration by judging the energy use. Some of the systems also take into consideration the environmental impact through assessment of energy source’s environmental impact or through energy form factors and primary energy factors for the energy type.

For all systems the indicators and the subfields are mandatory but the criteria and requirement levels are different. The systems that take consideration to climatic zones allow buildings located in colder climate to use more energy and have more environmental impact, the systems should reformulate the criteria and requirements were consideration is not taken to climate zones. The requirements of the heat effect demand for buildings should not take consideration to the heating system because the heating system does not affect the heat effect demand.

At the moment the systems are undeveloped when it comes to consideration to the energy’s environmental impacts and should therefore revise this. Some recommendations for the judgements of the energy field is to allocate the energy use/ per person and to judge primary energy or carbon dioxide emissions, other emissions and to judge the energy’s environmental impacts from “the cradle to the grave”. However it can be problematic to judge primary energy because today, there are no standards for how primary energy factors should be calculated currently.
