Utveckling av typhus inför EUs Nära-nollenergikrav 2021 : En undersökning om hur ett typhus kan anpassas inför Nära-Nollenergikrav som införs 2021

With the EU's introduction of Near-zero energy requirements to be implemented in all member states by 2021, the construction sector faces a challenge in which all new building constructions are receiving tightened demands for energy conservation. In the latest edition of Boverkets Byggregler, Boverket, the Swedish National Board of Housing, has revised the energy conservation section as the first of two steps in the introduction of the Near-zero energy requirement in Sweden, where the method of calculating energy consumption is renewed and primary energy aspects are now being considered. As it is not yet completed what the exact level of requirement for Near-zero energy is, this study applies the proposal for Swedish application of Near-zero energy requirements published by Boverket in 2015, which proposes, among other things, which primary energy factors to use for different energy carriers and use this in combination with the new method of calculating energy consumption according to the latest edition of Boverkets Byggregler. In addition to investigating what Near-zero energy will mean, the study had as its main objective to investigate what measures can be taken to the model house, provided by Nordisk Boutveckling, to enable the building to meet the new requirements. The study was therefore designed as a parameter study, where various measures to improve the building's energy conservation were tested in the energy-calculation program VIP-Energy. The result shows that the building, which is considered to be of a typical construction standard, is able to meet the requirement when it combines existing solar cells on the roof with a battery that can store the energy produced during the solar hours and then use this to provide the building with electricity for heating, real estate energy and for the production of tap water instead of allowing the electricity to be sold or used as household-electricity. The result also shows that installing better windows is an effective measure if the building is to meet the energy requirements with a certain margin of safety. It also turns out possible to meet the requirements by improving the building with a number of measures and using district heating as a heating method
