Analys av hur byggnadens höjd påverkar energiförbrukningen i flerbostads- och kontorshus
This diploma work has been carried out in collaboration with the building contractor Sh Bygg Fastighetsutveckling AB in Uppsala with the intention to investigate how the height of a building affects various energy aspects such as transmission Losses, infiltration, and the specific energy usage. Three different reference objects have been studied. The reference objects have been simulated for four different heights in the calculation program VIP-Energy.The results show that an increase in floor number can lead to both advantages and disadvantages. As the number of floors increases, transmission Losses per square meter floor area decreases. However, as the height of the building increases, the reduction rate decreases.
CCCTB:s betydelse för gränsöverskridande förlustavdrag : - Resultatet av ett genomförande ur svenskt och EU rättsligt perspektiv
On the internal market within the EU, freedom of establishment under articles 49 and54 TEU stipulates that companies have the right to set up businesses in other MemberStates. On the internal market there are 27 different national tax law systems whichhave caused obstacles regaring taxation between Member States. These obstacles havebeen shown deterrent when a company enters a new market. One problem area is thelack of cross-border loss compensation for groups. This means that cross-bordergroups is over taxed when they are unable to set of gains against Losses.
Fruits of knowledge : a literature review of marketing strategies and mango production in Kenya
This report is a literature review that aims to describe marketing contexts for mango production in Kenya. The institutional conditions in the country are not well developed for marketing purposes, which causes many difficulties and problems for the society. In Kenya most mango producers are poor small-scale farmers with limited resources. Mango is a perishable commodity and to keep its value and quality it is essential to have the opportunity to sell the mangos in the right time. Inefficient and undeveloped infrastructure and marketing systems hinders the mangos to reach the market in time though, which causes large Losses of produce.The Kenyan mango production has increased during the last decade but due to market Losses for the producer, the small-scale farmers? profits have not improved.
Utvärdering av vattenrening och identifiering avförluster m a p energi vid Bravikens pappersmaskin 53
This Master degree project has been performed at the Braviken paper mill on papermachine 53 (PM53) which produces newsprint paper. The current economic situationhas contributed to declining demand for newsprint, which means it is extra important tobe competitive by high energy efficiency. Particularly as energy prices are expected torise when the economic growth returns.One way to increase energy efficiency is by reducing the water use in paper and pulpmills and consequently save energy through reduced heating of water. The thesis's maintask is to evaluate whether a water purification plant (microflotation plant) forpurification of process water in PM 53 is profitable. The microflotation plant enablesreuse of warm process water instead of losing the energy to receiving waters.
Resistenta rapsbaggar :
Oilseed rape crops are an important in southern Sweden because of the high intensity
of wheat growing. Pollen beetles are the most important pest in oilseed rape and
causes often economic Losses. Therefore it?s of great importance that we can control
the population density, e g by using insecticides if necessary, to avoid mayor yield
Losses.
In year 2000 pollen beetles were numerous in the province of Östergötland. The
farmers sprayed with insecticides several times, but with low effects on the beetles.
Field trials and laboratory experiments showed that pollen beetles had developed
resistance against pyrethroids.
Utveckling av Mätmetoder för Färdmotstånd
The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy Losses.A vehicle's energy Losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller Losses like vibrations are ignored.
Kreditbedömningsprocessen : Jämförelse mellan de fyra storbankerna i Sverige
The financial crisis in the beginning of the 1990´s the financial crisis had a strong impact on the Swedish economy. Some of the main actors in the crisis were the largest banks of Sweden which brought a huge amount of Losses on themselves. One of the main reasons for this was that the banks focused on volume increases rather than on credit Losses. The credit analysis process is performed differently these days and it is the development of this process that is the focus for the authors.This thesis is about the credit analysis process in the four largest banks of Sweden. The purpose of the thesis is to highlight which factors the banks include in the credit analysis process and in how small and medium size companies are treated in this process.
Alternativa byggsystem för att minska transmissionsförlusterna på miljonprogrammets byggnader
The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission Losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.
Utvärdering och åtgärdsförslag av energianvändning i kontorsbyggnad
AbstractEmbla 5 is an office building which has done a large improvement. The clients of this building has made an order of WSP and the student Anders Kempe to calculate the use of energy for the building, and after that result proposing further measures which can decrease the energy use of Embla 5.The ground for this report is when calculation of the present energy use of the building is stated. To make that information of a number of parameters such as envelope, the heating system and ventilation has been located and set in to the simulation program IDA ICE which calculate the energy use.To improve the energy use further this project has been concentrated to change the system of ventilation. Today the ventilation system is of the kind CAV (constant air volume) and the air flow is dimensioned for after recommendations from BBR and Arbetsmiljöverket in the office spaces. Consider that Embla 5 is an office building where the people only staying for 8-10 hours/day so was the ide to see how much energy saving if the air flow is reduced the time people not being in the building.
Övergödning av Mälaren : Betydelsen av antalet beviljade dispenser av stallgödselspridning vid Sagån
Eutrophication was recognized in the early 1900's and results in severe algal blooms, increased biomass production and eventually leads to an altered ecosystem. In Mälardalen we find the most eutrophic lakes. Most of the applied phosphorus and nitrogen into seas and oceans comes from agriculture, and the nutrients Losses are affected by local weather conditions and soil type. Guidelines for storage and distribution of manure were introduced in the 80s, and the rules were strengthened January 1, 2010. Localities and previous county administrations can whether there are special reasons, grant an exemption for manure application during winter-periods despite the current ban.In this essay I have examined how many exemptions of manure application that has been granted at the Sagån river, and what implications it has for the eutrophication of Lake Mälaren.
Tidspress och ekonomiskt risktagande
Stress and time pressure is more present in todays labor markets. In financial markets a securities broker is forced to take decisions on investments under high cognitive load and under extreme time pressure. The research of decision under risk gained new ground with the development of the prospect theory and gave us new insights to the decision making of men. Prospect theory has shown that people are risk seekers when dealing with loss decisions and risk avert when dealing with profit decisions. The value function are defined over gains and Losses.
Design och konstruktion av mätuppställning för induktiv mätning av magnetisk spinndynamik
Development in spin dynamic occurs in the whole world because of therising demands on fast electronic storage for example hard drivesand RAM (Random Access Memory). Measuring the spin resonance of amaterial gives you the insight of the theoretical speed for amagnetic memory. This means the maximum storage speed is below thefirst resonance. All magnetic materials have different propertiesthat will inflict the resonance frequency which brings that theconstructors of memories need to know which magnetic material theywill use to obtain best results. In the market for normal users themaximum storage speed in a RAM memory is 1.6 GHz.
Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua
Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield Losses are followed by large economical Losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.
Expansionsmaskiner istället för strypventiler - en effektivisering
In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but Losses occur in form of exergy. The aim of this thesis is to reduce the Losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.
Svartrost, Puccinia graminis f. sp. avenae, epidemiologi och bekämpningsstrategier i Mälardalen
Stem rust, Puccinia graminis, has caused enormous yield Losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.
