Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.

Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.

Operabyggnaden placeras längst ut på piren och tar hela dess udde i anspråk. Operan riktar sig mot staden. Byggnadens storlek och koncept kräver viss rymd och ljus runt sig varför valet av plats blev naturligt. Den stora operavolymen skärs itu i flera delar och de olika volymerna binds sedan samman av en stålkonstruktion som på vissa ställen fungerar som ett orangeri medan den på andra ställen är en öppen pergolastruktur. Växtligheten används som ett material och ger intressanta rum, skuggspel och klimat. Orangeriet/pergolan löper igenom och runt byggnaden och såväl personal som besökare rör sig på gångar genom orangeriet/pergolan och upplever olika typer av rum, på olika nivåer. En önskan med uppdelningen i flera volymer är dels för att få in ljus på ett vackert sätt i en annars djup och mörk byggnad, dels för att försöka bryta ner skalan, samt även för att kunna ge personalen bra arbetsmöjligheter.

My Finnish grandfather had a passion for architecture, eventhough he wasn?t an architect. In the end of the 1950s he builta wooden summerhouse on a lot outside of a small villagecalled Lempäälä, close to the city of Tampere. Today the lotbelongs to my mother. Every time I visit our summerhouse, itmakes me want to do as my grandfather did ? to build a smallhouse next to it.My project is a proposal for a wooden house on mymothers lot.

More efficient energy consumption is essential to secure a sustainable future, not least within the building and real estate sector which answers for approximately 40 % of the EU countries total energy consumption. One part of EU: s work to reduce the energy consumption is the directive on energy performance of buildings which among other things have lead to stricter demands on energy performance in new and renovated buildings.One of the difficulties with making buildings more energy effective is that it often demands big investments and although it results in lower operating costs the extent of these savings and therefore also the repayment time can be difficult to decide beforehand. To make it interesting for property owners and also tenants to invest in energy efficient buildings powerful incentives are needed. Favorable loans to energy efficiency projects are one example of governmental instruments that have been tested in other European countries with good results.Reduced operating costs appear to be the main incentive for property owners to make their buildings more energy efficient. The best result of an energy efficiency project is usually achieved by cooperation between property owners and tenants but in order to make that interesting it is important that both parts can profit from the savings.

Energy price are on the way up to a high level that will not diminish in the future make us to focus more on the sustainable development for a better solution of residential houses. Passive house or low energy housing are one of the solution to make residential more environment friendly, in same time it´s a financial security using less energy, and saving money. The last 10 years in Germany and all around Europe the concept of passive house been developed, and people aim to know more about these concept that leading the market more attractive for passive houses. A passive house is a well designed building highly insulated and air tight with mechanical ventilated system for the whole building envelope that minimizes the use of energy for heating [1].The housing company Mimer has chosen to invest in low energy consumption in every new housing project.  These future plan projects are decided to use less than 75 kwh per square meter annually in purchased energy [2].This thesis is about new constructed passive houses, and focuses on the evaluations of the temperature, and moisture condition for attic, external walls and joist.

Kandidatprojektet Urban Building vid Hornsbruksgatan med undertiteln Hornsbruksgatan 2012 är ett arkitekturprojekt bestående av ett mindre antal sammanlänkade byggnationer i vilka bostäder, kontor samt kommersiell verksamhet inryms. Den övergripande volymen består av en tydligt långsmal kropp som är placerad längs med gatan. Stor vikt i projektet har lagts vid den arkitektoniska upplevelsen, materialval och beständighet. Gestaltningsmässigt har inga hinder funnits för eklektiska och anakronistiska influenser..

If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.

This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.

This Master thesis is about a postal- and telegraphic building in Eskilstuna, Sweden. The construction methods for the specific building and buildings in general from the same time are described. The purpose of the report is to describe the loads acting on the building and how it has been built and why it has been rebuilt during the years. After this, possibilities of reconstruction and adaptation for today?s demands can be evaluated.

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.

An increasing number of peole are resisting the attraction of living around nature and opting instead to spend their lives in cities. Parks and green areas play an important part in our well-being and we become fascinated with the diversity of nature, in which we find a peacefulness that is unique. Amongst other things, being surrounded by nature can reduce high blood presure, lower the production of stress hormones and stimulate the mind and our ability to concentrate. It is therefore vitally important to entice city residents to parks and green areas to improve their physical and mental well-being. Previous research has shown that humans are seeking for certain characteristics in the parks and green areas which they are visiting.

This diploma work was performed because the company Sveriges BostadsrättsCentrum, with the abbreviation SBC, had a need to gain insight into how changes in the Work Environment Act and related regulations which took effect January 1, 2009 affecting their work with the work environment. The changes mean that the client may hand over his work environment responsibilities to a contractor and that he has to select so-called building work environment co-ordinators. At SBC they are working as representatives for tenant-owner's association when a construction is about to be carried out. The purpose was to ascertain how changes may affect the work at SBC. The diploma work intends to educate the staff at SBC how work with the work environment would look like if they met the regulatory requirements.

When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

This thesis aims to increase understanding and knowledge of issues affecting the redevelopment of older office buildings to housing. The rising demand for housing in recent years has resulted in a need and an increase in cost housing projects. The need has led property owners wanting to build old office buildings to apartments. The case study is carried out in Lycksele town and in close contact with consultancy TM (Technician Mercantile) ? consulting, which has operations in the area.
