En stor problematik för att kunna bygga fungerande bostäder och kontor i Stockholms Stad idag är bullers påverkan från stora trafikplatser i staden. För att bostäder och kontor som staden har behov av ska kunna uppnå de krav Boverkets byggregler ställer för buller idag, behöver ytor vid bullerutsatta platser redan vid planeringsskedet för fastigheter i innerstaden beaktas. Ett hinder för att minska bostads och kontorsbristen i Stockholm är de bullerkrav som Boverkets byggregler ställer på ytorna i innerstaden, i samband med trafikökningen som medför en ökad buller. För att kunna lösa problemet från de utmaningar som finns för bostadsbristen i Stockholm kan hotell byggas på ytor i staden som är belägen nära trafik. En önskad effekt av att bygga hotell i sådana ställen är att kunna skärma av överflödig ljud in mot bostadsområden då Boverket inte ställer krav för bullers påverkan för hotell på fasad, även om rekommendationer finns för att uppnå en bra akustisk komfort inomhus. Att hotell byggs på fastigheter nära trafikområden i Stockholms tätort kommer också gynna den sociala utvecklingen i staden då man öppnar möjligheter för flera olika folkgrupper att mötas och träffas i en och samma punkt. Stockholm är idag en stad som utvecklas inom turismen och allt fler besökare kommer till staden vilket ställer stora utmaningar för hotellverksamheten och den utbud Stockholm har för turisterna att kunna bo på. Att nyttja ytor i innerstaden och tätorten i Stockholm som utsätts för buller som tex. fastigheter nära trafikplatser är en förutsättning för hotellbyggnation, då akustisk komfort för tillfälligt boende inte är ett krav från den svenska förvaltningsmyndigheten för boende dvs. Boverket. Detta examensarbete redovisar en studie på gestaltning av ett hotell som ska projekteras på en ljudutsatt plats i Stockholms Stad. Den valda fastigheten är belägen på Årstafältet som ligger söder om Stockholm och utsätts idag för höga bullernivåer pga. Huddingevägen som är en högtrafikerad bilväg. Problematiken med platsen för att kunna bygga bostäder, skolor eller kontor är att den valda fastigheten utsätts för hög buller som inte klarar Boverkets krav för bullernivåer på fasad. Då Boverket inte har ljudkrav på fasad för hotell, skapar detta en möjlighet att kunna bygga ett hotell på Årstafältet. / One major problem today in Stockholm City is to be able to build functional housing and offices becuase of the impact from the noise large interchanges distribute in the City. In order to build housing and offices it is important to achieve the requirements that Boverkets Byggregler, which is the Swedish rules for constructions. The county in Stockholm has to plan and observe the noise exposed properties in the inner City. One obstacle to build more housing and offices which the city needs, is the rules and demands on the areas but also the growth of the traffic in Stockholm city. This problem results for increased noiselevels which also affects the acoustic comfort for housig and offices. To be able to solve the problem for the challenges that is caused by the lack of housing in Stockholm, hotels can be built on these areas that are located close to traffic in the city. In order to solve this problem a hotel that screen the exessive noise towards residental areas can be a solution, because Boverket does not require any guidelines and regulations for noise on hotel constructions. The fact that hotels can be built on properties that is close to the traffic can benefit the social development of the city. A hotel can open opportunities for different people and groups to meet in the same point which can be used to increase the city´s social development. The tourism in Stockholm City is developing a lot today and more visitors visits the city day by day. The increase of visitors creates challenges for the range of hotels in the city. Utilizing areas in the inner city of Stockholm and urban areas that are exposed to noise from traffic is an advantage to build a hotel since Boverket does not require any benchmarks for noise. To make use of these kinds of properties, can also increase the range of hotels for the visitors in the city. This project will present a hotel that is located in Årstafältet in the southern part of Stockholm City. Årstafältet is a place that is exposed to high noise because of the highway on Huddingevägen that passes through the place. The problem with the location is the traffic noise which has a negative effect on housing constructions in the area. The noise problem in the area gives the chosen property good conditions for building a hotel and allows the residents close to the hotel property, to be less affected by the noise level coming from the traffic jam.

The National Board of Housing, Building and Planning have been conducting housing needs assessments since 1995 (Boverket 2015). The latest assessment was conducted in 2015 and showed that 71,000 homes will need to be built annually by 2020. To be able to contribute to building more homes, Willhem AB is carrying out a project called ”Så bygger vi för alla”. As part of the work, this thesis will examine the building rules and how they can contribute to innovation. The purpose of this thesis is to investigate which rules, laws and norms we have to keep to in Sweden regarding housing construction. The aim of the work is to investigate whether the regulatory framework can create creativity amongst the players in the market. This thesis is limited to examining which laws, government policies and eventual municipal requirements that exist in Sweden. Therefore, industry rules, such as the AMA, and contracting regulations, such as AB and ABT, will not be taken into consideration. The survey is also limited to newly built multifamily houses only. Finally, the reference objects that are studied in the thesis will be in Sweden and be limited to being either construction-technical or plan-based innovative and have been recently executed. This thesis is based on the existing regulations and theories from previous studies. The data collected for this survey will be studied from a qualitative point of view. The survey aims to investigate a number of reference objects more thoroughly and conduct interviews with key people involved in the project, which means a qualitative approach is best suited. In 1987, Sweden received a new building legislation according to Örnhall (2017), which has resulted in a transition from specification requirements to functional requirements in order to increase the liberty in housing production. However, according to Örnhall (2017 the new legislation has contributed to a wider picture of the regulatory framework. The National Board of Housing, Building and Planning is the authority that has the overall responsibility for community planning, urban development, construction and housing (Nordstrand 2008). The most important laws and government policies that the social planning sector primarily have to obey are the Planning and Building Act (PBL), the Planning and Building Regulation (PBF) as well as and the Swedish National Board of Housing, Building and Planning (BBR) (Örnhall, Swedish Construction Service 2017a). The Planning and Building Act (SFS 2010:900), PBL, regulates the planning for land and water whilst the responsibility for maintaining the regulations lies with the municipalities. The purpose of PBL is to promote social development for long-term, equal, social and environmental sustainable development for today’s society and future generations (SFS 2010: 900). When creating new homes, special consideration should be given to long term use of the home (Boverket 2016). At the interview stage, six areas emerged that were considered to be particularly problematic or interesting for the development of innovative and cheap housing. These areas were; accessibility, municipal requirements, rules, advice and interpretations, energy, innovation and development, and the ability to build for everyone. I perceived the accessibility aspect as very complex. Several interviewees argue that the accessibility requirements entail an increased cost for new builds, in one case it was even expressed that today’s availability requirements means the housing becomes less accessible to a larger group. The rules for creating an inclusive society also emerged at the interview stage while another recurring opinion is the renewal of the legislation. Several interviewees stated that they consider the regulations to be outdated and need to be updated according to today’s society. Based on this, I found The National Board of Housing, Building and Planning requirements contradictory whilst providing support for innovation, many requirements inhibits the development of housing. Therefore, extensive research should be carried out on how people in Sweden want to live today; thereafter the regulations can be updated according to today’s needs. In one way or another, all reference objects have been at the forefront when it comes to housing development. A common factor for the various reference objects is that a major problem was identified in all projects, which led to a product or solution being developed. They show that there is not one solution to the problem, but that different solutions can be found to achieve the same goal: better housing for more people.

År 1987 trädde en ny byggnadslag i kraft, Plan- och bygglagen(PBL). I och med den nya lagen minskade kommunens och byggnadsnämndens kontroll av projekteringshandlingar och besiktningar ute på arbetsplatsen. Efter lagändringen beror den slutgiltiga kvaliteten på en byggnad i större utsträckning på byggherrens och entreprenörernas egenkontroll. P.g.a. olika intressekonflikter inom kommunen, och att det kan förekomma starka kopplingar mellan byggherre och entreprenör, är det inte alltid självklart att kommunens tillsyn vid nybyggnation gällande till exempel egenskapskrav på energihushållning och värmeisolering utförs tillfredsställande.Med ovanstående i åtanke undersökte vi fyra flerbostadshus, två i Värnamo kommun samt två i Kristianstad. Vi undersökte om husen uppfyller de ställda värmeisoleringskraven enligt BBR(Boverkets Byggregler) 9 Kap. samt vilka krav som fanns med i respektive projekts kontrollplan. Endast ett av de fyra husen uppfyllde de ställda kraven. I kommunens kontrollplaner för de undersökta objekten ställs krav på värmeisoleringsberäkningar men några beräkningar på detta finns ej arkiverade hos kommunerna. / In 1987, a new law of building became effective, Plan- och bygglagen(PBL). The building committees' inspection of construction sites and documents decreased. The final quality of the buildings now depended in greater extent on the property developers and the contractors internal control. Due to different interests within the municipality and because of strong connections between property developers and contractors, it is not always a matter of course that e.g. the inspection of thermal insulation and energy housekeeping is executed in a satifactory fashion. With the above in mind we examined four multi-dwelling buildings, two in municipality of Värnamo and two in Kristianstad. We examined if the buildings comply with the thermal insulation requirement according to BBR (the swedish building code) and which requirements that were stated in the different projects documents of inspection.Only one out of the four buildings complies with the requirements according to BBR. In the municipality documents there are requirements of thermal insulation calculations but there are no documents that verifies that such calculations have been executed.

Den 2 juli 2014 blev det enligt lag tillåtet för en- och tvåbostadshusägare att uppföra en bygglovsbefriad komplementbyggnad på max 25 kvadratmeter på den egna fastigheten. Rapporten undersöker vilket genomslag lagändringen har haft i Stor-Stockholm, Stor-Göteborg och Stor-Malmö. Undersökningen visar att lagändringen ännu inte har haft något stort genomslag. I rapporten undersöks även en utvald del av marknadsaktörers utbud av attefallshus avsett som komplementbostadshus.  Ett attefallshus utformas med miljövänligt hållbara material och inspireras av Vitruvius tre principer för god arkitektur. Huset konstrueras med avsikt att uppfylla kraven som ställs i PBL, PBF, BBR och EKS. Målet med de framtagna bygghandlingarna är att få startbesked från byggnadsnämnden i Växjö.

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.

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.

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.
