The aim of this project has been to make an addition to an existing apartment block in Gävle, Dalapalatset. Dalapalatset was built between 1896 and 1899 and was designed by architect Nils Nordén and was planned to be built in three phases. The first two phases were built, but the last one never began. Now the block has a closed brick wall facing east. In the mid-1920s, city architect Gunnar Wetterling designed a proposal to complete the block, but this was never built. The intention of this project was to develop a new proposal for an addition, containing a program that is a continuation of the program of the existing building, residential apartments and commercial spaces. The fundamental issue has been how the addition should relate to the existing, whether the addition should adapt and conform to the existing in the interior as well as on the exterior or if it should be completely separated from the existing building and how to design for today’s life with building techniques of today. / Detta projekt omfattar en utveckling av ett tillägg till ett befintligt bostadskvarter i Gävle, Dalapalatset. Dalapalatset byggdes mellan 1896 och 1899 och ritades av arkitekten Nils Nordén och var planerad att byggas i tre faser. De två första etapperna byggdes, men det sista påbörjades aldrig. Idag avslutas kvarteret av en sluten brandvägg av tegel mot öster. I mitten av 1920-talet ritade den dåvarande stadsarkitekten Gunnar Wetterling ett förslag på en tillbyggnad, men detta genomfördes aldrig. I detta projekt har ett nytt förslag på en avslutande tillbyggnad utvecklats, innehållande ett program som fortsätter på det befintliga kvarterets program, bostadslägenheter och kommersiella lokaler. Den grundläggande frågeställningen har utgjorts av hur tillägget ska förhålla sig till den befintliga, huruvida den nya delen bör anpassa sig till och överensstämma med det befintliga såväl interiört som exteriört eller vara helt skild från den befintliga byggnaden samt hur utrymmena kan utformas för dagens sätt att leva och med dagens byggnadsteknik.

Bostadsinvesteringarna har tagit fart de senaste åren i Sverige. Den gynnsammaprisutvecklingen har resulterat i fler nybyggnadsinvesteringar och antaletproducerade lägenheter har varit stort. I detta marknadsläge blev det allt merattraktivt att teckna förhandsavtal på nyproducerade bostäder. När prisfallet sedankom under hösten 2017 för att därefter stagnera, har det uppstått en ökad osäkerhetpå den svenska bostadsmarknaden. I den stagnerade marknaden harbostadsutvecklarnas finansieringsmodell avseende förhandsavtalen fått störremedial uppmärksamhet. Oftast handlar det om den kritik och de brister vad gäller deförhandsavtal som tecknats och som har uppenbarat sig allt mer när marknadensvängde. Detta har gett upphov till ett ökat antal tvister mellan bostadsutvecklare ochköpare såsom konsumenter, i ett försök att häva dessa avtal. Mot denna bakgrundhar idag allt fler hushåll avvaktat med att teckna förhandsavtal, framför allt påbostadsrätter där tillträdesdatum ligger långt fram i tiden.I uppsatsen har intervjuer hållits med bostadsutvecklare i Stockholm, finansiärer ochjuridiska ombud för konsumenter för att sammanställa synen på marknaden idag vadgäller förhandsavtal för nyproducerade bostadsrätter hos olika aktörer. Vidare har enfallstudie genomförts genom en djupdykning i två olika bostadsutvecklaresaffärsmodeller och styrprocesser, för att kunna granska underliggande orsaker till atttvister med köpare har uppstått. Syftet med uppsatsen har varit att identifiera definansiella orsaker som ligger till grund för de problem som idag uppstått påmarknaden, samt ge förslag på lösningar som vidare skulle kunna undersökas iämnet. / Residential investments have increased over the past years in Sweden. Thefavorable price trend has resulted in more investments in new-construction, and thenumber of new-built apartments has been large. During this market situation, itbecame increasingly attractive to sign pre-sale agreements on newly producedcondominiums. Since the prices subsequently fell in Autumn 2017 and thereafterstagnated, there has been an increased uncertainty in the Swedish housing market.In this stagnated market, the residential housing developers’ financing models for thepre-sale agreements has received greater medial attention. Most of this attention hasbeen about criticism and shortcomings regarding the pre-sale agreements that havebeen signed and which have become increasingly appeared when the marketswung. This has led to enhanced numbers of disputes between residentialdevelopers and buyers, as an attempt to lift these agreements. Today an increasingnumber of households have been waiting to sign pre-sale agreements, especially oncondominiums where access dates are well ahead.In the paper, interviews were carried out with housing developers in Stockholm,financiers and legal representatives for consumers in order to compile the view of themarket today regarding pre-sale agreements for newly produced condominiums,from various players. In addition, a case study has been conducted to get a deepdive into two different housing developers' business models and control processes,in order to be able to examine the underlying reasons why any disputes with buyershave arisen. The purpose of the thesis has been to identify the financial causes thatunderlie the problems that have arisen in the market today, and to give suggestionsfor solutions that could further be investigated on the subject.

The waste energy is a very important factor that affects environmental crisis in the world. Buildings have been consuming nearly 40% global energy production, and the building industry has been identified as a sector where substantial savings may occur. In residential buildings, the energy consumption is strongly related to air conditioning systems. In Maceio, the use of passive strategies as natural ventilation seems irrelevant by construction sector. This case results in well, fair, bad or very bad residential apartments in relation to climatic conditions. The apartments located in west quadrant have smaller price than apartments located in east quadrant. It is an attractive factor to the consumer purchase apartments badly adapted to climate. This situation contributes with wild use of air conditioning systems. The use of these equipments results in costs of purchase, operation and maintenance. Not always the accounting oh these values are properly considered in the moment of apartment s acquisition. Facing this context, the present work intends to evaluate the economical impact of air conditioning systems use in residential apartments in Maceio city, Brazil. Emphasize the link between waste energy and financial costs in long term involving this question. By case study, be adopted one methodology that analyze: apartment s energy performance in some variable using the EnergyPlus software; natural ventilation performance in some orientation, by qualitative analysis in water table models; economic analysis based on monthly consumption of energy for different situations simulated, accomplish comparison between energy costs for air conditioning system use and the price of apartments. The analysis have shown the energy costs in long term for all situations simulated represent large portion of integral apartment s value. When the monthly cost is applied in savings account, most situations pay total value of apartments. In all cases, this investment overcome the economy make possible in acquisition of west apartment invest in same circumstances. Results lead to the conclusion that the use of passive strategies of thermal comfort is a very good economics strategy for the consumer, and the purchase of badly adapted apartments is very expensive, above all when be considered the economical impacts for air conditioning systems use in long term. / Fundação de Amparo a Pesquisa do Estado de Alagoas / O desperdício energético é um dos fatores de maior impacto sobre o desequilíbrio ambiental enfrentado pelo planeta. As edificações respondem pelo consumo de aproximadamente 40% da energia gerada no planeta, sendo o setor da construção civil identificado como uma área de grande potencial para combater o desperdício energético. Nas edificações residenciais, o consumo energético está fortemente relacionado aos sistemas mecânicos de controle térmico como os sistemas de ar condicionado, por exemplo. Em Maceió, o Mercado Imobiliário parece não buscar soluções arquitetônicas que se aprofundem no uso de estratégias passivas de conforto térmico, como a ventilação natural, por exemplo. Na referida cidade, é identificada a existência de apartamentos residenciais bem, razoavelmente, mal ou pessimamente orientados frente aos condicionantes climáticos. Os apartamentos voltados para o quadrante oeste (posição poente) possuem preço menor que aqueles voltados para o quadrante leste (posição nascente), sendo esse um atrativo para o consumidor adquirir apartamentos mal adaptados ao clima. Essa situação contribui com o uso desenfreado de aparelhos de ar condicionado. O uso destes equipamentos acarreta em custos de aquisição, operação e manutenção dos mesmos. No entanto, a contabilização destes valores nem sempre é devidamente considerada no momento da aquisição dos bens imóveis. Diante desse contexto, o presente trabalho avalia o impacto econômico decorrente da utilização de aparelhos de ar condicionado em apartamentos residenciais de 02 quartos na cidade de Maceió/AL. Busca enfatizar o elo existente entre o desperdício de energia e o custo financeiro em longo prazo envolvido neste processo. Através de um estudo de caso, adotou-se uma metodologia na qual foram analisados: o desempenho energético dos apartamentos sob diferentes variáveis, utilizando o software EnergyPlus; o comportamento da ventilação natural nos apartamentos de acordo com as diferentes orientações geográficas, através de análises qualitativas utilizando maquetes em Mesa D água; análises econômicas baseadas no consumo médio mensal de energia para as diferentes situações simuladas, realizando comparações entre o custo energético para utilização de ar condicionado e o preço de mercado dos apartamentos. Os resultados demonstraram que os custos energéticos em longo prazo de todas as situações simuladas representam uma grande parcela do valor total do imóvel. Quando o custo mensal é aplicado em caderneta de poupança, a maioria das situações paga, com sobras, o valor total do imóvel. A economia possibilitada pela aquisição do apartamento poente aplicada em caderneta de poupança durante longo prazo é superada, em todos os casos, pela aplicação em iguais condições do custo energético mensal para uso de ar condicionado. Desta forma, conclui-se que a utilização de estratégias passivas de controle térmico representa um grande meio de economia para o consumidor, e que a compra de apartamentos mal adaptados ao clima é extremamente dispendiosa, sobretudo quando considerado o impacto econômico derivado do uso de ar condicionado em longo prazo.
