ENERGIEFFEKTIVISERING? Av lamellhus byggt på sextiotalet

TitleEnergy-efficiency ? of Slab blocks built in the sixtiesAuthorsRichard Sandahl and Kim SöderbergEducationHalmstad University, Section for economy and technique Construction Engineering 180 ECTSSupervisorMargaretha Borgström, Universitylector construction physics, Halmstad UniversityContact person at HFABUlf Johansson Heating, sanitation and energy co-ordinatorReportExamination paper at the construction engineering program is performed in cooperation with HFAB (Halmstad real estate concern Inc.)AimThis examinations work is done in cooperation with HFAB and there project on the block around the street Maratonvägen. HFAB:s dwelling stock on this area are going through a bigger renovation and in relation to this they are looking on the possibilities to make this building more energy efficient. That is why this examination paper has as purpose to answer the question if it is possible to make Slab blocks built in the sixties more energy efficient. This is done by calculate energy efficient measures on a chosen apartment block at Maratonvägen in Halmstad, in an energy and expense perspective.MethodThe examination paper is based on different methods, mainly calculation but also qualitative conversation studies, economic calculations and literature studies.

Taktikröstning i svenska val : - existerar det och påverkades det svenska valet 2010 av det?

The number of parties in the Swedish parliament has increased from five to eight during the last twenty years. The political agenda is still based on a two-block system with the consequences that the number of parties in each block has increased. To be represented in the parliament, a party needs at least four per cent of the total votes in the election. If only one party fails to achieve that, the whole block will lose the election to the other block. This could encourage voters to vote tactically for the small parties in the block to ensure that the block wins the election.

Förbättring av U-värde i träkonstruktion för fönster med Aerogel

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..

Den mobila prefabriceringsfabriken : Ett nytt produktionskoncept

This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality.

Axial- och gradientkrympning hos golv på mark enligt Eurokod 2 : Sprickbredders beroende av betongkvalité, tvångseffekter och armeringshalt

AbstractConcrete foundation slabs are usually exposed to unilateral drying during the curing process. The unilateral drying causes an axial shrinkage and a concave curvature of the construction. The curvature results from the fact that the upper part of the slab is drying and shrinking faster than the lower part. This is called gradient shrinkage.A problem occurs when the slab is considered fully restrained by adjoining structural parts. The deformations caused by axial contraction due to the constant part of the shrinkage and the curvature caused by gradient shrinkage of the slab are then prevented by the fact that the slab is fully restrained.

Three block war : en studie av utbildningsdokument

Uppsatsen är skriven som en del i de studier i krigsvetenskap jag erhållit på Yrkesofficersprogrammets sista termin.Syftet med uppsatsen är att bidra till utvecklingen av de soldatutbildningshänvisningar som nyttjas vid Artilleriregementet. Frågeställningarna lyder: -          Tränas soldaterna vid Artilleriregementet, enligt utbildningsdokumenten som nyttjas, för att klara av de krav som ?Three block war? ställer? -          Kompletteras eventuella brister vid utbildningen på Artilleriregementet, genom utbildningen som sker inför internationell tjänst? Metoden som använts är deskription med tekniken litteraturstudier. Begreppet "Three block war" beskrivs därefter analyseras utbildningsdokumenten för att besvara frågeställningarna.  Analysen visar att soldater som gjort värnplikten på Artilleriregementet och därefter genomgått den gemensamma utbildningen som ges utlandsstyrkan fortfarande har ett behov av utbildning. Detta kopplat till om soldaterna skall klara av att verka i ett område som karaktäriseras av "Three block war"..

SAMVERKAN STÅL/BETONG : Kontroll av kapacitet hos blockankare i Connector Samverkansbalk

In April 2007 we contacted Lennart Augustsson at Designpartners AB in Västerås. He came up with the idea to investigate and evaluate their construction of a interaction beam, CSB-beam. CSB is short for Connector Interaction beam. The beam is based on a horizontal C-profile of high-tensile steel and in the bottom of the profile are vertical flat bar welded so called block connectors. These block anchorsare also made of hightensilesteel.

Att dela ett bostadshus eller kommunikationen till staden

Detta projekt handlar om hur vi kan bo nära varandra i en stad och samtidigt ha tydliga gränser kring de ytor vi delar. Var möts vi i staden? Var är vi tillsammans i bostaden? När övergår den privata sfären till gemensam?Kommunikationen i dagens bostadshus har reducerats till minsta möjliga vilket helt tar över dess utformning. Att istället se denna som en social yta har potential att skapa ett levande atmosfär där mer privata funktioner delas med kommunikationen. Delandet handlar också om de saker vi har i hemmet, är delning av kökmaskiner och städredskap ett möjligt sätt att spara energi? Hur kan vi bygga för att främja detta?I processen har jag försökt definiera vad som skapar ett attraktivt boende i stadskontext och se hur detta går att applicera i morgondagens Stockholm.

Jämförelse mellan olika träbjälklag

Wooden joist slabs is a common type of floor in residential buildings. Higher demand and production of residential buildings increases the possibilities of profiting by optimizing the system of joists in a variety of areas. Spring and deflection is something most people can relate to since it?s not that uncommon to hear furniture rattle when you walk over a wooden floor. To remove the presence of those kinds of vibrations the system of joists have to be made stiffer than the standard joist construction that is used in today?s constructions.

Indelningsändringar : en studie om varför Norra Sandsjö kommun, Bringetofta församling och Norra Sandsjö församling delades i samband med att Sävsjö kommunblock bildades

This paper is about a new organization how to get smaller communities to join together and become much larger. The purpose is to find out why Norra Sandsjö community and Bringetofta and Norra Sandsjö parishes were separated when Sävsjö municipality block was formed. The purpose is further to find out what the councils of Norra Sandsjö, Nässjö and Sävsjö, the church council and the people who lived in the area thought about the decision that was made by the executive organization in this matter (länsstyrelsen in Jönköping). Voting was arranged amongst the people, who lived in the specific area that in the first inquiry was suggested to be connected with Nässjö municipality block. The source material gives the result of this voting and the opinions of Norra Sandsjö, Nässjö and Sävsjö communities in this question.

GALS,Design och simulering för FPGA med VHDL

Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be reduced. GALS (Global Asynchronous Local Synchronous) is a wrapper that wraps a synchronous block and provides it with a clock. Multiple GALS-elements will make the whole system. The clockfrequency may be independently adjusted between each block.

Tilla?ggsisolering och fuktproblem i grundkonstruktionen platta pa? mark : En fallstudie i flerbostadshus inom stadsdelen Sa?tra i Ga?vle

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.
