In 1874 the first Swedish construction norm was written. This stated that no houses were to be built with timbered frames over two floors. It took almost a century before the norm was changed again in 1994 and allowed Swedes to build high buildings with wooden frames again. Although the constructions with timber did not increase, the Swedish government started in 2002 a national timber plan "

Vi har upprättat en jämförelse mellan solcell och solfångare som kompletterande energikälla i befintlig byggnation. Jämförelsen är tillämpbar vid liknande scenarier och kan anpassas för framtida pris- och kostnadsändringar. I samarbete med PEAB Energi ska resultatet från kalkylerna används senare till att inspirera gemene man till utvecklingen och en utökad användning av förnybara energikällor.

Installation of heat recovery system in multi-family houses - A comparison between a central system and an individual system. Energy- efficiency of buildings is a popular subject of discussion. If we are going to reduce the energy consumption in our buildings we need to install more effective ventilation systems that utilize the heat in the exhaust air. Exhaust and supply air ventilation with heat

The purpose of this report is to compare different heating devices for future apartment blocks. The compared heating devices were district heating, geothermal heating, pellets heating and pellets heating combined with solar heating. The two main elements in the report compare the different alternatives with regards to their environmental impact and their lifecycle cost. The heating devices are als

Backup heating for passive houses. This paper consists of information and calculations considering the possibility for the passive houses in Björka 16:1 in north Helsingborg to be heated by district heating, heat pump or an electric boiler. This paper can be used as an inspiration for future projects considering passive houses, as the market for such houses is tiny in Sweden today. Helsingborgshem

Verification of the cleaning routines in a nut roastery The purpose of this report is to verify if the cleaning routines used in a specific nut roastery give an adequate cleaning and make the products microbiologically safe. Furthermore, controls of the products have been made with regard to allergens, personal hygiene, cooling, water content, water activity and the level of oxygen left in the pac

This postgraduate thesis examines various assumption models for energy usage for water heating used in Sweden. The models are compared with the measured energy use in a number of small apartment buildings. Norway and Finland currently use standard models for energy calculations during the production of new buildings but in Sweden the planners are free to select an appropriate model of their choice

Sammanfattning Cook-chill är en tillagningsmetod utvecklad för att tillgodose konsumenternas bekvämlighetskrav på färdigmaträtter. Cook-chill är tillagning av mat i stora kvantiteter med snabb efterföljande nedkylning. Nedkylningen ska snabbt till rekommenderad temperatur, från 90 °C till 3 °C inom 90 minuter. Ett avkylningsskåp med hög kylkapacitet används med fördel. Det är av denna anledning so

There are different kinds of foam with varying stability and appearance and a number of factors which affect this. The volume and the stability of the foam are important for the beer industry due to the fact that many consumers find this a measure of quality. There are many different methods for measurement of the physical properties of beer foam. Unfortunately none is used as a standard. A method

Hur planerar man i ett tidigt skede för eventuella utbyggnader.

Detta examensarbete är utfört i samarbete med Tankens Trädgård, en förening som startade 2004. De strävar efter att skapa ett affärsnätverk för kvinnligt företagande. Via Campus Helsingborg sökte de studenter som kunde ingå i projekteringsgruppen Design och kommunikation. Tillsammans skulle vi formge ett mobilt rum, influerat av renässansen i Florens. Grundtanken är att skapa en mötesplats där man

Bakgrund i utbildningssystemet krav på uppdatering av kunskaper, ev. finns någon utredning eller t o m proposition från utbildnings departementet. Järnvägsskolans policy för fortbildning/grundutbildning. Sammanfattande kravbild inom jänrvägssektorn, tex kännedom om regelverk Intervjuer med ansvariga hur man anpassar sig till marknadens krav intervjuer med företag: vilka krav de ställer på sina ans

The theme of this essay has gradually grown as a way to merge the individual courses of Food Technology, Lund University, with a special interest regarding probiotics/lactic acid bacteria (LAB). We have studied the process of fermentation in sauerkraut with a hypothesis that “LAB will, with the environmental conditions they create, compete out other microorganisms”. We compared 3 different kinds o

Vattenskador är en av byggbranschens stora utmaningar. Badrum/våtrum är den värst drabbade delen i en bostad som är relaterade till fuktskador. Enlig Vattenskaderapport från 2008 uppstår ca 39 % av vattenskadorna i en bostad i våtrum. 50 % av alla golvrelaterade skador inträffar i våtrum. Med skadorna följer stora ekonomiska förluster. Det uppskattas att det går åt ca 100 miljoner kronor i veckan

This work is about creating a uniform language for Formidabel. At Formidabel, a panel of seven people was selected for sensory tests. One of the selected sensory tests was an identification test. The purpose of this test is to teach a new panel to detect aromas. The panel tested mashed potatoes containing different kinds of spices for each test. They were also tested with an identification thresho

Genom experimentella mätningar har vi tagit fram grafer för luftflöden och förlustfaktorer i spalt mellan vind- och regnskydd i putsade tvåstegstätade fasader. Detta är av betydelse för att veta att inträngande fukt kan torka ut så att konstruktionen inte tar skada. Mätningar gäller för konstruktioner med spaltbildande läkt från Lindab och Europrofil samt även för fallet med helt tom spalt. ResultBy experimental measurements we have developed charts for air flows in the space between the wind- and rain cover in parget two-step sealed facade. This is a presumption to give penetrating moisture a possibility to dry-out and the construction not to take damage. All measurements are based on structures with ventilated air space with profiles from Lindab and Europrofile. The results are then comp

The world has witnessed a remarkable growth over the last 50 years and the urbanisation is becoming a growing problem in many countries. In 1950 29 % of the world’s population lived in urban areas, in 2003 the urban population had grown to 48 %. In order to create a healthy environment in the fast growing cities it is important to have an infrastructure that works. Creating such a city is somethin
