Redan 2008 satte EU upp klimatmål om att minska utsläppen och spara energi. Minska utsläppen av växthusgaser med 20 procent jämfört med 1990. Den totala energiförbrukningen ska minska med 20 procent jämfört med denprognostiserade trenden. 20 procent av den totala energiförbrukningen ska komma från förnyelsebara energikällor. Genom att då tillämpa en miljöcertifiering på byggnader är detta ett steg på vägen för att uppnå desatta målen. Med miljöcertifiering menas att byggnaden betygsätts med hänsyn till uppnåddmiljöpåverkan utifrån en tredjepartsgranskning. Utifrån ett certifieringssystem får en byggnad ettcertifikat som visar dess miljöprestanda.Det här examensarbetet har som syfte att ta fram ett förslag på miljöcertifieringssystem åtByggbolaget i Värmland med riktlinjer att det skall vara så enkelt och kostnadseffektivt sommöjligt, för att sedan tillämpa detta på Etapp 3 på Bryggudden i Karlstad. Detta med anledning avatt Byggbolaget i Värmland ser ett ökat behov på marknaden utav dessa kunskaper. Decertifieringssystem som ingår i urvalet är, EU GreenBuilding, Leed, Miljöbyggnad och Breeam SE.Utifrån litteraturstudien kunde slutsatsen dras att det certifieringssystem som var lämpligast atttillämpa på Etapp 3 på Bryggudden i Karlstad var Miljöbyggnad. Detta val grundade sig på attByggbolaget i Värmland efterfrågade ett enkelt och kostnadseffektivt miljöcertifieringssystem medrelevanta miljövärderingar. Den största svårigheten med att tillämpa Miljöbyggnad på Etapp 3 varatt byggnaden redan var färdigprojekterad när certifieringsprocessen inleddes, vilket begränsademöjligheten att styra teknik och systemval. En miljöcertifiering enligt Miljöbyggnad på Etapp 3skulle leda till byggnadsbetyget silver. / Back in 2008, the EU set climate targets to reduce emissions and save energy. Reduce greenhouse gas emissions by 20 percent compared to 1990. The total energy consumption will be reduced by 20 percent compared to the forecasted trend. 20 percent of the total energy consumption from renewable energy sources. By applying environmental certification of buildings, this is a step to achieve the set targets. Environmental certification means that the building is graded with respect to the achieved environmental impact based on a third-party review. Based on a certification, a building certification shows its environmental performance.This degree project aims to produce a proposal of environmental certification for Byggbolaget i Värmland based on the guidelines that it should be as simple and cost effective as possible, and then apply it to Etapp 3 on Bryggudden in Karlstad. This is to the fact that Byggbolaget i Värmland sees a growing need for these skills in the market. The certifications included in the sample is, EU GreenBuilding, the LEED, the Miljöbyggnad and the BREEAM SE.Based on the literature review it could be concluded that the certification appropriate to apply to Etapp 3 on Bryggudden in Karlstad was Miljöbyggnad. This choice was based on the request of Byggbolaget i Värmland of a simple and cost-effective environmental certification with the relevant environmental values. The main difficulty in applying the Miljöbyggnad on Etapp 3 was that the building was already fully planned when certification process began, which limited the ability to control technology and system selections. Environmental certification according to Miljöbyggnad on Etapp 3 would lead to construction grade silver.

Climate conditions nowadays are looking critical where the construction and property sector is a major contributing factor. The construction industry stands for one third of Sweden’s total energy use, which has led to different environmental goals and energy requirements that the industry needed to adapt to reduce environmental emissions. In association with this has durability and environmental certifications become one identity marker for companies that strives to make a difference and for users who choose to support them. Growing demand and increased environmental awareness have characterized the construction industry. The most popular environmental certifications on the Swedish market today is: BREEAM, LEED, GreenBuilding and Miljöbyggnad. BREEAM and LEED are the most recognized systems internationally and considers both the building and and the surrounding area. GreenBuilding focuses only on the buildings energy consumption and how to reduce it. Miljöbyggnad is the commonly used system in Sweden and focuses on the building itself.  Miljöbyggnad is a Swedish certification system that is handled and developed by Sweden Green Building Council (SGBC) since 2011 and focuses on the building itself. The building is assessed by 15 different indicators within three segments: energy, indoor environment and material. This Work is limited to examine only Miljöbyggnad four indicators: energy consumption, solar heat load, heating needs and ventilation regarding an ongoing housing unit in cooperation with SWENCN AB.  The aim of this work was to calculate monthly energy consumption for the reference building. Furthermore, was the aim to rate the four indicators according to Miljöbyggnad grade system: bronze, silver and gold and finally see what happens if the household electricity is neglected and can energy efficiency regarding household electricity paradoxically result in that the building appears to be inferior.  The result of this thesis shows that the buildings active heating season is five out of twelve months. Solar thermal load is calculated to a value of 66 W/m2 floor area and because of that did not meet up the criteria for bronze. Heating needs meets up to the criteria for bronze with a value of 21,5 W/m2 , Aom.  and the buildings energy use for gold with a value of 49 kWh/m2, (Atemp), year. Household electricity contributes to increased passive heating and counts because of that as “free energy” which decreases the need for active heating, the building is considered as better. If the household electricity instead is neglected it will increase the heating demand and the building appears to be inferior. The conclusions of this work indicate that the big uncertainty lies in judging how people's habits affects the energy use. The building is currently under production which has led to that static average numbers have been used, and because of that margin of error can in some cases become big. As a result of that should any changes and adjustments updates when the building is put in use. It's easier and more effective to reach gold in the planning stage when there are opportunities to choose building components with lower U-value.
