Purpose: This work is based on the problem with the product cross-laminated timber and its properties in the event of fire. The reason for the problem is the glue used in the product and the lack of requirements for adhesion at high temperatures. Due to this, there is a risk of delamination in the event of a fire, i.e. that the wooden slats that constitute the largest component in the CLT wood fall off during the course of the fire and contribute to extra energy. Method: The work is built up of two different methods, first a literature study and then an experiment. The literature study focuses on the National Board of Housing, Building and Planning's building regulations, the production of cross-laminated timber and what happens in the event of a fire. The experiment was carried out at Fågelbacken in Västerås, where help from the rescue service was available. The informative part of the report begins with a subject reference framework where the first part consists of information about the National Board of Housing, Building and Planning's requirements and ordinances that are based on the Planning and Building Act and the Planning and Building Ordinance. This study describes the experiment, everything from the application of the fire protection treatment to the design of the fire test. The materials included in the fire test are described and any certifications they hold are mentioned. The results section presents the results of the literature study and the fire test. Results: The four pieces of wood showed different results after fire, as three out of four showed cracks between the slats on the fire-affected surface. No piece of wood delaminated or had loose slats, however, the cracks are interpreted as meaning that the glue did not withstand the temperature that the fire generated, and melted. The depths of the carbon layer, on the other hand, were significantly protected by the fire protection treatment as there was a maximum difference of 7 mm between one of the fire protection-treated pieces of wood and the untreated piece of wood. The burning time of the fuel pool varied. The course of fire for the pieces that were treated with fire protection was strong with large flames and large, black smoke pillars. Conclusion: The conclusion of the thesis is that the fire protection treatment has a good effect on the depth of the carbon layer, which delays the risk of delamination. The fire protection treatment also has a good effect on the adhesive in some of the cases when no or few cracks between the slats were seen.

Sveriges befolkning ökar och i takt med detta behöver fler bostäder byggas. En flexibel lösning till problemet skulle kunna vara modulbostäder. Detta examensarbete undersöker i huvudsak två frågeställningar. Dels hur modulerna står mot de krav som ställts på den svenska byggnadsmarknaden. Dels hur valet av ventilation kan påverka modulbostäderna. Detta genomförs med en jämförelse av kostnader, energiberäkningar och krav mot en referensmodul. Tanken med modulbostäder är att bland annat minska byggtiden genom att producera modulerna i fabrik. Modulerna kan också byggas för att vara möjliga att flytta efter behov.   Studien har genomförts genom faktainsamling från litteratur samt intervjuer med ventilationsföretag och företag som jobbar med moduler. Avgränsningar har bland annat gjorts till att bara studera flerbostadshus.   Resultatet tyder på att modulbostäder i teorin uppfyller de krav som ställs från bland annat Boverket. Företag satsar mot hållbara byggnader och försöker bygga sina moduler mer som ett vanligt flerbostadshus. Detta ger en längre livslängd och energieffektivare byggnader.   Ventilationen visade ett resultat som var svårtolkat. Mycket beror på byggnadens utformning och valet av aggregat från leverantör. Detta tillsammans med vaga värden från ventilationsleverantörerna gjorde det svårt att avgöra vilket system som vore mest fördelaktiga. Val av system kan väljas från mjukare värden som för- och nackdelar. Beroende på om bostäderna behöver vara flexibla så är det att föredra med individuella system. Ser man till kostnad däremot så kan ett centralt system vara med fördelaktigt. / The Swedish population is growing and as well the demand for housing construction. A flexible solution to this problem could be modular houses. This thesis examines two main issues. Issue number one focuses on how modular houses can achieve compared to the Swedish standard building regulations. The other issue focuses on how the choice of ventilation system can affect the building. To achieve an answer, comparisons of costs, energy calculations and regulations against an reference housing. The idea with modular housing is to reduce the construction time by building the modules in a industry. A module can also be made portable depending on where it is most needed.   This study has been carried through by gathering information from literature and interviews with ventilation- and modular housing companies. Limitations has been made for instance, to apartment buildings.   Results show in theory that modular housing compares well to regulations put up by Boverket. Companies working with modular houses has focused more on building modules that can be compared to other types of housing buildings. This gives the modules a longer life span as well as more energy efficiency.   It is a bit more difficult to analyze the results from ventilation systems. A lot is depended on the modules design and also the choice of unit. This along with vague data from the ventilation companies made it difficult to choose which system would be more effective. To be able to choose a system from this thesis, softer values like pro and cons to be given in consideration. Depending on the need of the building, different choices could be made. If flexibility is important then a individual system may be preferred. While if cost is more important, then central system should be the choice.

Purpose: This study aims to investigate and compare a range of factors that can contribute to differences in energy calculations and the energy declaration. Method: To investigate this, a literature study has been carried out where the collection of facts and information is used to complement the case study that has also been carried out. The case study consists of energy calculations that have been both calculated and compared for a larger and a smaller one-family house. To examine the impact of the various factors, one factor at a time has been changed in the calculations to clarify its outcome. To make the work as realistic as possible, two existing houses are used as reference objects. This means that both floor plans and material choices are taken from a house manufacturer’s drawings. Results: The result shows that living habits are a difficult factor to assess when it comes to energy use in a building because there are no specified values for each sub-item. The energy use that can be read out is a total sum of the different parts of the energy use. Examples of parts that are included in the total energy use are domestic hot water use and household electricity use. Despite the difficulty in distinguishing which item is the major contribution factor to the differences in measured and projected energy use, most agree that living habits are the biggest factor. Conclusions: It becomes easier to identify what it is in living habits that is the difficult-to-assess factor if all individual living habits were specified with their own energy calculations and measurement values. This could even be a tool to investigate and further investigate the differences that arise in the future. Finally, it can be good to assist with skill development for all homeowners in terms of energy efficiency in their living habits to reduce ignorance about the impact of user habits on energy use.

Studien undersöker hur effektiv plan- och bygglagen är för att skydda kulturvärden vid bygglovsprocessen genom att kartlägga förändringar på särskilt värdefulla villor och undersöka om dessa skett med eller utan bygglov samt om de lett till förvanskning. Studien fokuserar på villor klassade som särskilt värdefulla i kommunala kulturmiljöunderlag i Örebro och Karlstad, med syfte att ge en helhetsbild av hur kulturvärden hanteras i bygglovsprocessen. Undersökningen visar på att en övervägande del av villorna förvanskats sedan de kulturmiljöinventerades och att förvanskningarna till störst del skett utan bygglov. Vidare påvisas att en majoritet av de förändringsåtgärder som skett i enlighet med bygglov inneburit att villorna förvanskats. Kommunernas kulturmiljöunderlag används bristfälligt i bygglovsprocessen vilket innebär att kulturvärden negligeras. Ytterligare en faktor som bidrar till denna negligering är att begreppen varsamhet och förvanskning som återfinns i PBL är allmänt hållna, vilket öppnar upp för tolkningar om dess innebörd. För att öka skyddet för villors kulturvärden behöver värdena integreras i detaljplaner som är juridiskt bindande. / The study examines how effective the Swedish Planning and Building Act is in protecting cultural values during the building permit process by mapping changes to particularly valuable villas and investigating whether these changes occurred with or without a building permit and whether they led to degradation. The study focuses on villas classified as particularly valuable in municipal cultural environment documents in the cities Örebro and Karlstad, aiming to provide a comprehensive picture of how cultural values are managed in the building permit process. The investigation shows that most of the villas have been degraded since their historical values were inventoried, and most of the degradations occurred without a building permit. Furthermore, it is demonstrated that most of the changes that occurred in accordance with building permits resulted in the villas being degraded. The municipalities' cultural heritage documents are used inadequately in the building permit process, which means that cultural values are neglected. Another factor contributing to this neglect is that the concepts of caution and degradation found in the Planning and Building Act are generally formulated, allowing for interpretations of their meaning. To increase the protection of the historical values of villas, these values need to be integrated into legally binding detailed development plans.

The content of greenhouse gases in the atmosphere is increasing resulting in climate change and efforts to stop the negative trend need to be intensified. The energy use in the Swedish residential and service sector constitutes 40 % of the total energy use of 378 TWh in the country. Nationally there is a target to reduce the energy use per heated area with 20 % to 2020 and 50 % to 2050. Energy renovation of buildings from the Million Programme is foreseen to be able to contribute to achieving the targets owing to the large building stock and energy efficiency potential. In the master thesis cost optimal energy renovation strategies are investigated for two multi-family buildings in Linkoping built during the Million Programme, one with an unheated attic and one with a heated attic. The thesis is carried out by using life-cycle cost optimisation (LCC-optimisation) by utilising the software OPERA-MILP, developed at Linkoping University. The aim of the thesis is to obtain the energy renovation strategy that is optimal from an LCC-perspective and to investigate the energy reduction and LCC. Optimal energy renovation strategies are also investigated for energy renovation to levels of the Energy Classes of the National Board of Housing, Building and Planning in Sweden and the stricter limits for nearly zero-energy buildings (NZEB) that will likely come into force in 2021. Greenhouse gas emissions and primary energy use are also investigated for the different cases with the purpose of putting energy renovation in relation to climate impact. Local environmental factors are used for district heating while electricity is assigned values based on the Nordic electricity mix and Nordic marginal electricity respectively. The current LCC and annual energy use is 2 945 kSEK and 133 MWh for the building with an unheated attic and 3 511 kSEK and 162 MWh for the building with a heated attic. The result shows that LCC can be reduced by approximately 70 kSEK and 90 kSEK respectively. The optimal solution constitutes of a window change from windows with U=3,0 W/m2°C to windows with U=1,5 W/m2°C and results in a reduction of the energy use by 13 % and 15 % respectively. LCC increases with 240 kSEK for the building with unheated attic and decreases with 18 kSEK for the other building when Energy Class D is reached. Energy Class C is attained through an increase in LCC by 300 – 590 kSEK and Energy Class B through an increase by 1610 – 1800 kSEK. It is not possible to reach Energy Class A or the future requirements for NZEB (55 kWh/m2Aheated) with the energy renovation measures that are implemented in OPERA-MILP. The largest energy reduction that can be attained is approximately 60 %. The most cost optimal insulation measure is additional insulation of the attic floor/pitched roof followed by additional insulation of the ground concrete slab. It was shown to be more cost efficient to change to windows with U=1,5 W/m2°C in combination with additional insulation compared to changing to windows with better energy performance. For greater energy savings additional insulation on the inside of the external wall is applied, while insulation on the outside of the external wall is never cost optimal. To reach Energy Class B installation of HRV is required which gives a large increase in cost. Less extensive energy renovation is needed to reach the energy classes for the building with heated attic compared to the building with unheated attic. The annual use of primary energy in the reference case is 22 MWh for the building with an unheated attic and 26 MWh for the building with a heated attic. The emissions of greenhouse gases are 18 tonnes CO2e and 22 tonnes CO2e per year respectively when the emission factor of the Nordic electricity mix is applied and 20 tonnes CO2e and 25 tonnes CO2e respectively when the Nordic marginal electricity is applied. The yearly primary energy use can be reduced with up to 7 MWh through energy renovation. When the energy renovation leads to an increase in electricity use the primary energy can however increase with up to 12 MWh. The yearly greenhouse gas emissions can be decreased with up to 14 tonnes CO2e. When Nordic marginal electricity is applied to estimate the emissions of greenhouse gases for an energy renovation strategy that leads to an increase in electricity use the result is less beneficial from a climate perspective compared to when Nordic electricity mix is applied.

EU har ställt höga krav på energianvändning i byggnader genom ett nytt direktiv där respektive medlemsland har fått i uppdrag att ta fram gränsvärden för energianvändning i just sitt land. I Sverige har Boverket fått detta ansvar. I och med det skärpta krav som har föreslagits finns en orolighet i byggbranschen att det kommer att bli svårt att uppfylla det. Tillverkare av småhushar ofta en standardiserad konstruktion som de nu kan behöva ändra på. Syftet med detta examensarbete blev därför att undersöka om en småhustillverkare behöver förändra sin standardkonstruktion, och i så fall vilka förändringar som kan göras, för att uppnå det nya kravet för energianvändning. Genom att studera nuvarande energikrav och Boverkets förslag på nytt krav samt teorier inom byggnadskonstruktion har den teoretiska grunden för examensarbetet lagts. En litteraturstudie har dessutom gjorts över tidigare studier inom området, där framför allt förbättringsåtgärder för att få energisnålare hus har varit till stor hjälp för detta arbete. Studien av en småhustillverkare har genomförts genom att energianvändningen av ett småhus i standardutförande har tagits fram i simuleringsprogrammet IDA ICE. Studerat hus är en trävilla med bergvärme och FTX-ventilation beläget i klimatzon 1. Efter simuleringen har åtta förbättringar i husets konstruktion gjorts med nya simuleringar för att identifiera vilka av dessa förbättringar som är lämpliga att utföra. De mest lämpade förbättringarna har slutligen kombinerats ihop för att uppnå det nya energikravet. Studien visar att nuvarande konstruktion inte uppfyller kommande krav. Utifrån de avgränsningar som har gjorts rekommenderas att följande tre åtgärder vidtas; installation av en värmepump med COP 4 istället för 3, fönster och dörrar med U-värde 0,8 W/(m2*K) istället för 1,2 W/(m2*K) samt ytterväggar med U-värde 0,1 W/(m2*K) istället för 0,137 W/(m2*K). Dessa rekommendationer utgår från att det föreslagna kravet även gäller för klimatzon 1. / The EU has demanded lower energy consumption in buildings through a new directive where each member state has been assigned the task of developing new energy consumption targets for their respective country. In Sweden, Boverket has been assigned this responsibility. There is a concern in the Swedish construction industry that it will be difficult to meet these new requirements. Manufacturers of small houses usually have a standardized design that they now may need to adjust. The purpose of this thesis was therefore to investigate whether a single-family house manufacturer needs to change its standard construction, and if so, what changes could be made to achieve the new requirements for energy usage. By studying current energy requirements and Boverket's proposal for future requirements as well as theories in architectural engineering, the theoretical basis for the thesis has been laid out. A literature study has also been performed of previous studies in the field. Particularly studies of home improvements to get energy-efficient houses have been of great help for this work. A single-family house has been constructed and simulated in the IDA ICE simulation program. The house was made out of wood with a ground source heat pump and FTX ventilation located in climate zone 1. Eight improvements in the house design have been studied with new simulations to identify which of these improvements are appropriate to implement. The most suitable improvements have finally been combined to meet the new energy requirements. The study shows that the current house construction design does not meet future requirements. Based on the delimitations that have been made for this thesis, it is recommended that the following three measures are to be taken; A heat pump with a COP of 4 instead of 3, windows and doors with a U-value of 0.8 W/(m2*K) instead of 1,2 W/(m2*K) and outer walls with a U-value of 0.1 W/(m2*K) instead of 0,137 W/(m2*K). These recommendations are based on the assumption that the proposed new requirements are also applicable for climate zone 1.

Today, there is a housing shortage in the larger cities. This together with the long housing waiting lists makes it difficult for younger people to make a housing career and invest in a condominium. In 2014, the Swedish Parliament introduced the reform of attefallshus with the aim of reducing the housing shortage in the country and facilitating entry into the housing market. The work studies whether an attefall block can be a favorable housing concept and an example of such a housing concept is designed. The purpose of the study is to analyze which legal obstacles limit a block of attefall houses and whether the housing concept can possibly reduce the housing shortage. To answer the study's purpose and questions, interviews were conducted with experienced people in the field. The results show that very few attefallshus are currently used as dwellings. Instead they have other functions. Furthermore, the results show that the legal obstacles that limit an Attefall block are, according to the study, availability to existing one- or two residential buildings that allows additional buildings of in total 30 on the plot. The interviewees believe that the concept should change the name to single-family neighborhoods and establish detailed development plans specifically for this. The conclusions are that an attefall block will not be economically favorable, is impracticable and not a solution for housing shortages.

I denna fallstudie jämförs en gammal gårdsbyggnad uppförd 1898 med kraven som ställs vid nybyggnation idag. För cirka 120 år sedan ställdes inte lika stränga krav på byggnationen som idag. De krav som undersöks handlar om hållbarhet och konstruktion. Syftet med studien är att skapa en bättre förståelse för varför dagens krav finns genom att undersöka en byggnad som är uppförd utan dessa krav. För att nå klimatmålen, som Sverige har antagit, finns det bland annat krav på byggnaders energieffektivitet som kan mätas genom att beräkna byggnadens primärenergital. Energieffektiviteten påverkas delvis av hur välisolerad en byggnad är varför kravet som ställs på en byggnads U-värde (värmegenomgångskoefficienten) också är intressant att undersöka. Gränsvärden på primärenergital och U-värde finns i Boverkets byggregler, BBR. Krav på konstruktionen finns i den internationella standarden Eurokod och de nationella valen i EKS. Beräkningar har gjorts på tak och bärande väggar för att kontrollera att de har tillräcklig bärighet. Även primärenergitalet och U-värden har räknats ut samt risken för fukt i den solida tegelväggen. Resultatet visar att konstruktionen klarar de krav som ställs i Eurokoderna och EKS och att byggnadens funktion bara uppfyller ett av de krav som ställs i BBR. Resultatet är i linje med tidigare forskning som har genomförts på energiprestanda hos gamla byggnader och visar på att det genom renovering, utan att skada byggnadens kulturvärde, är möjligt att uppnå dagens krav även om just den byggnaden som undersökts här inte når kraven. / This case study compares the function and framework of a building from 1898 with the requirements regarding sustainability and strength when building today. The purpose of this study is to get a better understanding of the requirements by investigating a building that was built without them. The requirements on a new building’s sustainability are today applied to old buildings that undergo extensive renovation. Two measurements to ensure high sustainability are primary energy and the heat transfer coefficient. A well-insulated building has a low heat transfer coefficient and will require less energy to heat and therefore be more energy efficient and more sustainable. Calculations have been made to determine the strength of the roof and the walls according to the Eurocodes and the nationally determined parameters, EKS. The primary energy and heat transfer coefficient has been calculated and compared to the mandatory provisions, Boverkets byggregler, BBR. The result shows that the framework is strong enough to take care of the loads it is exposed to. Most of the requirements regarding sustainability fail to be met. Although in conclusion it should be possible to meet some, if not all, the requirements with further renovation without harming the cultural value of the building.

Denna studie presenterar en jämförelse mellan KL-trä och olika former av betong (armerad/oarmerad och platsgjuten/prefabricerad) som väggmaterial i byggnadskonstruktioner. Syftet är att analysera deras respektive miljöpåverkan och kostnadseffektivitet. Trots en initialt högre kostnad per kvadratmeter, har KL-trä en betydligt lägre miljöpåverkan, vilket medför en nettovinst för miljön jämfört med betongväggarna. Bland betongalternativen uppvisar oarmerad platsgjuten betong en balans mellan lägre kostnader och mindre CO2-utsläpp. Studien lyfter fram behovet av standardiserade, pålitliga data om miljöpåverkan inom byggindustrin för att stödja hållbara beslut. Den pekar på potentialen i ytterligare forskning som syftar till att reducera både kostnader och miljöpåverkan för KL-trä, för att främja dess bredare användning i byggsektorn. Studien erbjuder därmed viktiga insikter för att driva en mer hållbar och ekonomiskt lönsam byggindustri. / This study presents a comparison between CLT and various kinds of concrete (reinforced/unreinforced and cast in place versus prefabricated) as wall material in building constructions. The purpose is to analyse their respective environmental impact and cost efficiency. Despite an initially higher cost per square meter CLT has a considerably lower environmental impact, which entails a net profit for the environment compared to the concrete walls. Among the concrete options, walls without rebar and cast in place exhibits a balance between lower costs and CO2eemissions. This study highlights the need of standardized, trustworthy data of the environmental impact in the construction industry to support sustainable decisions. It points to the potential in further research which intends to reduce both cost and environmental impact for CLT, to further promote its use in the construction industry. The study thus offers important insights for driving a more sustainable and economically profitable construction industry.

Andelen miljöcertifierade byggnader har under 2000-talet ökat. Inom kommersiella fastigheter är det numera inte lika ovanligt att kontor miljöcertifieras och en ny aspekt har etablerat sig bland certifieringssystemen - människans välbefinnande. WELL Building Standard är ett hälsocertifieringssystem som sätter människan i centrum. Systemet har under 2017 gjort inträde på den svenska marknaden och det första projektet står klart för verifiering under våren 2018. Detta projekt är Castellums huvudkontor i fastigheten Klassföreståndaren 3 i Stockholm, även kallad Flat Iron Building. Syftet med studien är att bidra till större kunskap om WELL Building Standard under svenska förhållanden och underlätta fortsatt etablering av hälsosamma byggnader. Målsättningen med studien är att identifiera lärdomar från certifieringen av projektet enligt WELL Building Standard - New &amp; Existing Interiors - genom att besvara följande frågeställningar: <ol type="1">Hur förhåller sig det slutgiltiga resultatet i Flat Iron Building gentemot intentionerna med att   certifiera projektet och syftet med WELL Building Standard? Med avseende på Flat Iron Building i Stockholm, vilka utmaningar finns vid kombination av de sju koncepten i WELL Building Standard samt svenska lagar och regler? Hur arbetar olika aktörer vid införande av hälsocertifieringen WELL Building Standard i Flat Iron Building? För att undersöka implementering av en hälsocertifiering i projektet utfördes en genomgång av litteratur inom svensk lagstiftning och regelverk, miljöcertifieringssystem samt hälsocertifieringar. Litteraturgenomgången innefattar en kartläggning av WELL Building Standard gentemot Arbetsmiljöverkets föreskrifter, Boverkets byggregler, Miljöbyggnad och LEED. I undersökningen utfördes även en fallstudie med kvalitativa intervjuer och platsbesök. Intervjuerna genomfördes med involverade aktörer samt brukare av kontoret. Studien ger unika lärdomar gällande projektets intentioner och utfall, hur implementeringen av indikatorer kan utföras i Sverige samt arbetssätt vid genomförande av en hälsocertifiering. Exempelvis kan WELL, enligt studien, användas som verktyg för att uppnå beställarens målsättning. Studien lyfter fram både utmaningar och vad som underlättats när systemet kombineras med de svenska regleringar som styr byggandet, där utmaningar redogjorts i projektet kopplat till avsaknad av produktinformation gällande VOC-värden i möbler på den svenska marknaden. Arbetssättet vid WELL Building Standard kan enligt fallet likställas med hur aktörer arbetar i ett miljöcertifieringsprojekt. Likt ett sådant projekt krävs samarbete mellan samtliga inblandade parter. Vidare kan ytterligare lärdomar hämtas i studien som kan användas för att underlätta etablering av fler WELL-projekt. Dessa lärdomar är bland annat kopplade till tidsplanering, kommunikation, kunskap och stöd - däribland vikten av att få WELL att genomsyra alla steg av processen från planering till drift av fastigheten. Avslutningsvis kan de lärdomar som presenteras i detta examensarbete vara till nytta för den som innehar en samordnande roll i byggprojekt och vill arbeta med implementering av WELL Building Standard på den svenska marknaden. Studien kan även användas som referens vid fortsatt forskning inom WELL. / The number of certified green buildings has increased during the 21st century. Within commercial properties, such as offices, it is no longer unusual to use green building rating systems. Hence, new types of rating systems have arisen - those that promote human well-being. The WELL Building Standard is one of these new rating systems that puts the people inside the building at the centre. In 2017, the WELL Building Standard accessed the Swedish market and the first project is ready for Performance Verification in spring 2018. The project is Castellum’s Headquarter in Stockholm with property designation Klassföreståndaren 3, also known as the Flat Iron Building. The aim with this study is to contribute to a greater knowledge of how WELL Building Standard can be used in Sweden and thereby facilitate further establishment of buildings that promotes health and well-being of the building’s occupants. The objective with this study is to identify lessons learned from the certification process of the project according to WELL Building Standard - New &amp; Existing Interiors - by answering the following research questions: What is the outcome of the project in Flat Iron Building in relation to the intentions with using the rating system and the purpose of WELL Building Standard? Regarding Flat Iron Building in Stockholm, which challenges exists when combining the seven concepts of WELL Building Standard and Swedish legislation? How does project stakeholders collaborate during the implementation of WELL Building Standard in Flat Iron Building? To investigate the implementation of a wellness-oriented rating system a literature review about Swedish legislation was conducted. The review includes an overview of how WELL Building Standard compares to The Swedish Work Environment Authority’s Statute Book (AFS); National Board of Housing, Building and Planning’s Building Regulations (BBR); Miljöbyggnad and LEED. Within the investigation a case study with qualitative interviews was conducted, as well as an on-site visit at the headquarter. The interviews were held with different stakeholders in the project. The study contributes to unique lessons about the intentions and outcome of the project, how features can be implemented in Sweden and how project stakeholders collaborate during implementation of a wellness-oriented rating system. According to the study WELL can be used as a tool to achieve the property owner’s objectives. Furthermore, the study demonstrates features which are challenging or uncomplicated when combined with Swedish legislation. One of the challenges described in the project is the absence of product information regarding VOC values in furniture available on the Swedish market. The study demonstrates that collaboration between stakeholders in a WELL Building Standard project is similar with a green building project. In both cases it is important with cooperation between all parties involved. Further lessons can be found in the study to facilitate establishment of WELL-projects. These lessons are related to time management, communication, knowledge and support - for instance the importance of incorporating WELL in the entire building process from planning to management. The lessons presented in this master thesis can serve those who hold a coordinating position in construction projects and is interested in implementing WELL Building Standard in Sweden. The study can also be used as a reference in further research within WELL.
