Sandviksvägen 38 är ett av många flerbostadshus byggt under åren 1961 ? 1975, de såkallade rekordårens bostäder. Byggnaden står inför en omfattande renovering, och då finnsdet samtidigt goda möjligheter att minska byggnadens energiförbrukning. I studien undersöksoch beskrivs ett antal av de åtgärder som kan genomföras. Målet är att föreslå åtgärdspaketför att minska byggnadens specifika energiförbrukning med 20 respektive 50 procent jämförtmed dagens användning.

When it comes to the priority of a project proposal, a variety of factors is affecting theoutcome. In the municipal sector, factors of non- economic nature appears to be particularlyimportant when the organization is not intended to be profit-making.This study's research question is What problems can occur around an energy-efficiencyproject proposal in a municipal organization? The purpose of this study is to gainunderstanding of what possible problems an energy efficiency project proposal mayencounter, in the municipal implementation process as well as the problems of a changingownership can bring.To conduct this study, the method was qualitative in nature. We have cooperated withVarberg Energi AB and Varberg kommun, which has stood as respondents for the empiricalbasis of the study. In this study, we have conducted four personal interviews.In this study, we have found that there may be several problematic factors associated with anenergy-efficiency project proposal in a municipal organization.

yield optimization, wind energy, sustainability, maintenance..

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

I have in my thesis, examined the possibilities in terms of energy for a condominium association.To have an effective and good energy is becoming increasingly important with today's rising electric and oil prices. In my thesis I have used the condominium association Kärralyckan, which is situated in Falkenberg. The buildings at Kärralyckan are built in the mid-1970s, and are heated by electric radiators. The tap water is heated by an electric boiler.Based on that calculation I can show the various energyststem. The different solutions have been developed by contact manufacturers and installers through phone calls and e-mail.According to the results shows that geothermal heating has been a great solution for Kärralyckan.

The purpose of this survey was to map out the health pf some of the 11 and 12 years old children in the city of Umeå, as well as to find out what factors intend to influense the children´s health. A questionnaire was distributed in four 6th grade classes whitin the municipality of Umeå. Two of the schools were located in the city while two were located in near villages. This selection was decided in order to map out diffrences in health related to the children´s home environment. 80 pupils took part of this study.

This project investigated the current market regarding wireless net and the communication between the tools used for diagnostics/maintenance and an embedded system. Based on documentation obtained through interviews a demo system was created based on Bluetooth Low Energy (BLE) communication between an embedded system and an Android device.This report intends to describe the tools and methods used in the design of the demo system and the result of an analysis of the BLE communication.Bluetooth Low Energy is an exciting protocol with wide applicability within the industrial field. This project investigated the communicational possibilities between a Smartphone and a Raspberry Pi and based on the results that emerged the conclusion can be drawn that BLE is a protocol with many beneficial applications within industrial IT..

Inom EU vill man sänka energianvändningen med 20 % till 2020.Växjö kommunhus har gamla och ineffektiva installationer, samt ett dåligt isolerat och otät klimatskal.Denna rapport undersöker vad för slags inverkan byte av installationer, samt byte av klimatskal, har för inverkan på kommunhusets energianvändning. Till detta har energiberäkningsprogrammet VIP-Energy 1.5.5 använts.För att sammanfatta resultatet av arbetet så är det mest effektiva och lönsamma alternativet att byta ut installationerna, samt att kylbehovet ökar då man kraftigt isolerar detta hus..

The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

In cooperate with Asko Cylinda we have developed a new heat system too short the process time and reduce the energy consume in a dishwasher and still have it too be a class AAA. The environment and quality is important for the company too still be the number one on the market, If they want too keep that position the product developed of new innovations will be very important. The systems we have developed are more effective and reduce energy up too 25 %. The process time is reduced too less than two hours, from the today two and half-hour. The solutions are too heat up the rinse water and the dishwater at the same time, with a new heating system and it make are solutions unique and effective. Its good for the dish and the environment.

Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.

Mobile technology is developing quickly and becomming a part of daily life and communication. Bluetooth Low Energy is presented as a new way of mobile interaction. However there are not enough studies in this field on the interaction between mobile devices and the physical world. In order to understand user needs, and to encourage users to interact, we simulated an interaction process through designing and testing a prototype in a specific indoor environment. Prototype effectiveness and main characteristics for future mobile application was evaluated through a qualitative user study with 20 participants who interacted with our prototype..
