Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.

A growing number of cities and municipalities in Sweden begin to work with city models in 3D. For the most part the models are used for visualizations of ongoing planning processes, but also for the analysis of noise, shadow studies and environmental disaster simulations.Gothenburg continues to develop the use of 3D maps in municipal operations and is demanding a way to create building elements (walls), which generates in 3D buildings, from roof constructions that are mapped from the primary map. A method has been investigated in the present study. The results are then presented as a 3D model of buildings, along with a terrain map that will facilitate the localization of the area. The created 3D buildings are then compared with roof-data from the primary map to see how well they harmonize with each other.

The purpose of this thesis has been to signify what creates quality for the dwellers. Bycreating a definition of the term we have showed how well the qualitycriteria?s has been fulfilled in the newly built one family house area Pumpkällehagen in Viskafors.The questions the thesis gives answers to is: What is quality for the dwellers inhousebuilding of today? and How well have these quality aspects been carried out in tracthousing areas? These questions have taken us to our main goal: To describe what qualityfor the dwellers is and how well it has been carried out in a certain area.The literature review is describing what was published before the making of this thesis.From four different publications within the concept of quality an analysis template hasbeen enacted. This template has been used for our case study, but is also supposed towork in future analysis of tract housing areas.Interviews was carried out with the areas architects; Ola Nylander and Mattias Karlsson,as well as the client; Mikael Bengtsson. From these we have gathered their point of viewon the background of the area, as well as their view on the term quality for the dwellers.Our work has brought us to enact nine different quality aspects, which we considercreates quality for the dwellers:? The Non-measurable properties? The rooms relative connections? Sufficient and user-friendly property complements? The property complements connection to the apartment? Location of the apartment and connections to the environment? Opportunities of outdoor activities? Orientation and transportation within the area? The social unity? The cost of the apartment and its form of tenureFrom the case study, using the analysis template, we can state that Pumpkällehagen is avery successfully built area where most of our assessment criteria?s and quality aspectshave been fulfilled.

The focus of this two year master?s thesis in Library- and Information science is the study of two Swedish Public Library buildings with the examples Lomma and Halmstad. The main goal and purpose of the thesis is to try to uncover which views and values of the public library are expressed in the examined libraries; and to what extent these views manifests are shown in its architecture.The theoretical framework is based on Raymond Williams?s cultural concepts of effective, dominant culture and the two extremities of this culture, called residual and emergent cultures. A second aspect is Yi-Fu Tuans concepts of Space and Place.

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

This bachelor?s thesis examines the tradition of half-timbered buildings in V?stra G?taland County as there is a current lack of research on this building category in this region. The lack of knowledge may lead to the loss of potential cultural heritage values if these buildings do not receive attention. Therefore, the study aims to provide a more comprehensive understanding of its role within the region. The goal is to expand and nuance the existing research on the Swedish building tradition, particularly in V?stra G?taland County and the general Swedish half-timbered tradition.

Uppsala like many other Swedish cities is affected by heavy housing shortage, in terms of too few existing flats and residents within the city limits. Every semester thousands of new students are facing the same problems of finding themselves adequate accommodation. The waiting lists for flats and student-dorms are getting longer for each year, and the situation is just getting worse. Simultaneously, Uppsala?s ambition is to increase its population and expand as a Swedish metropolitan, according to the Swedish governmental environment goals. This paper investigates and analyses the possibilities of expanding a city?s population by building high-rise buildings.

The question of excessive global energy use needs to be solved. All energy production and usage have negative environmental impacts, which are best solved by reducing energy consumption and by using energy more efficiently. A large part of the Swedish energy use is concentrated to the building sector and to reduce the total energy consumption real efforts need to be made to make buildings more energy efficient.The aim of this study was to investigate how energy is used in one of Göteborg University?s buildings and to find measures that can be taken to improve its energy efficiency. The chosen building Zoologen, is used for research and education.The main method of the study is computer simulations of the present building and of possible energy reducing measures to be made in the future.

AbstractThis report has been developed in cooperation with Peab Region Bostad Göteborg, mentor at Krook& Tjäder (through Chalmers), and examiner at Chalmers University of Technology. The report is the result of a research of a building project, constructed by Peab. The report is investigating and it means to identify and evaluate qualities in the dwelling and its surroundings. Its purpose is to evaluate how the residents in a chosen housing cooperative enjoy living there. It shall, with help of chosen quality aspects, identify what expectations the residents had before moving in, how they experience the dwelling and its surroundings today, and what hopes they have for the future planning of the area.

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.

?A culture center should be visually welcoming as well as attract a diverse range of visitors with different backgrounds.? This was the client?s request for a new cultural center in Nairobi. The location is in the heart of Nairobi?s industrial area, near several existing buildings that are already in use by the culture organization known as Go Down. I have chosen to keep most of the existing buildings and to use my new building as a complement for the desired program.

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.
