Smarta Hus: Nya behov och lösningar med participativ design
In this Bachelor Thesis (20 p.), we present the history and development of
"Intelligent Houses", and most important- explore some of the future
possibilities in this area.
The project has been carried out through an interdisciplinary cooperation
between three different educations at the Blekinge Institute of Technology.
By conducting a dialogue with various actors with different professions, we
have been trying to identify needs within the concept of "Intelligent Houses",
were the end user is not only the tenant or homeowner.
Through Participatory Design methods, such as a Future Workshop, we have
brought the users together to discuss their own and each others needs and
hindrances in their respective work practice, and how intelligent house
technology could improve their work conditions.
We have also been testing a highly sophisticated
CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally
developed for regulating indoor climate systems.
Based on the needs we have found in our fieldwork, we have been looking at
possibilities to make multi user solutions with the sensor..
Energikloka hus i Järinge - energiteknisk uppföljning
Energy-wise houses in Järinge - technical follow-up The company JM built energy-efficient houses in Tensta in Stockholm. They have built a total of 16 houses divided into two parts of A-houses and B-houses. The buildings are an attempt by JM to minimize energy-use of the buildings without affecting the comfort and living standards. The project aims to examine the data for the 16 houses on the basis of data and produce a report showing how the buildings worked through a technical perspective. JM approximates that the purchased energy will not be higher than 95 kWh/m2 per year.

May 2010 a project called drop-in sports was started to get boys and girlsin the ages of 13-20 more physically active and keep them away from committing crime. With the slogan ?come as you are, whenever you want and do what you want for free ? spontaneous sports was organized. To evaluate the project a research of the activity was carried out, where two of the objectives were to investigate how responsibility and empowerment is taken. Twelve hours of observations studies were used to collect data about leadership decision-making and democratic values in forms of respect, everybody?s right to play and influence.
Fuktproblem i chilenska småhus
Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.
Beräkning av energianvändning i svenska småhus
An energy calculation model for Swedish houses that is fast, flexible and user-friendly has been developed within the framework of this thesis. The model also provides a set of actions which may be investigated in the model based on savings and payback period. Energy use in a house depends on the technical conditions, such as building envelope and heating systems, which outdoor climate the house is exposed to and who lives in the house. Energy use for a house can be divided into heating, hot water and household electricity. There are several methods to calculate the energy use of a house. This report summarizes the methods that may be suitable for a fast and user-friendly calculation model.

"Vaktmästaren är tokig på oss" : Förskollärares syn på inomhusmiljön i Reggio Emiliainspirerad verksamhet
The aim of this study is to examine what preschool teachers within Reggio Emilia inspired early childhood education express as important regarding the physical indoor environment in preschools. The study is implemented with a qualitative method and is based on four interviews with preschool teachers that have been involved in a course on Reggio Emilia. The interviews were complemented with four observations on the departments where the preschool teachers work. A second aim of this study is to examine how the relationship between the teachers statements correlate with the environment they have created at their preschool. The collected material was gathered and then categorized.
Positionering och kartuppbyggnad med avståndsmätande laser
This master thesis includes a description of how a number of sensors are put together in a sensor platform. It also gives a description of how localization and mapping has been performed with data collected from the sensor platform. Localization is a prerequisite for most of the tasks that can be requested from an autonomous mobile robot. In many situations the GPS signal is not available and hence an additional localization system is required. One approach is to apply localization based on landmarks extracted from the robots surrounding.
Energianalys av MVG-gallerian, samt en jämförelse av beräkningsprogram
På uppdrag av Sweco Systems i Umeå har detta examensarbete utförts under våren 2013. Syftet var att undersöka huruvida något av de energiberäknings-program som används på företaget kan anses vara lämpligt vid energikartläggningar av befintliga fastigheter.Inledningsvis utfördes en energikartläggning av fastigheten Odin 12 i Umeå, som i huvudsak utgörs av gallerian MVG. Med resultaten från denna energikartläggning som grund beräknades därefter fastighetens energianvändning i två olika program ? VIP-Energy och IDA Indoor Climate and Energy.Resultaten från den inledande kartläggningen visar att fastigheten har ett lågt behov av fjärrvärme, vilket förklaras av fastighetens höga elförbrukning. Den stora användningen av el genererar stora mängder internvärme som, förutom att sänka fjärrvärmebehovet, även medför att fastigheten under hela året har ett kylbehov.Utvärderingen av de två beräkningsprogrammen visar att VIP-Energy är ett lämpligt program att använda vid energikartläggningar.

The research for this report includes measurements on existing buildings, calculation models on the building envelope for analyses and the ingoing materials of the envelope. The health aspect of moisture problems related to ?sick building syndrome? has been included and interviews have been conducted to gather relevant information.A study of the American system, ASHRAE, American Society of Heating, Refrigeration and Air Conditioning Engineers and the standards used in Singapore has been made to highlight the difference.
Ideon Forskningspark : yttre arbetsmiljö i ett industriellt landskap
Abstract
Ideon Science Park was built on the edge of Lund city in mid-80ies. The Science Park was surrounded by open farm land and Lunds Faculty of engineering(LTH). The architecture, the facades of the buildings, were placed to face the faculty.
The Science Park has since then grown, and the actual front of the building is no longer faced towards LTH. The people working at Ideon are met by the backside, the meeting with Ideon is primarerly a meeting with fields of parkinglots.
The initiative to this thesis was taken by Ikano Fastigheter AB, one of two real estate owners of Ideon Science park. Their aim is to make the area easier to orientate, they want it to be more internally connected and with a stronger identity.
The thesis is mainly dealing with two questions conserning Ideon Science center.
Akustik och säkerhet i inomhusarenor
The background to the study is that within the next ten years about 50 new multi-purposeindoor arenas will be built. These are used for various events such as sports, concerts, etc. In order to achieve a high level of security in the case of danger alarm signals and alarmmessages must be heard well by the visitors. ÅF-Ingemansson wanted to show builders the importance of good speech perception and that it is not observed in arenas today. They conducted technical tests on two large multi purpose indoor arenas to develop parameters that affect speech perception in the arena.To get a subjective view of how these arenas are experienced a survey was created.
Kroppsligt samspel i den fria innomhusleken : Fenomenologiska funderingar
Syftet med vår studie är att utifrån ett fenomenologiskt perspektiv bidra till förståelsen för hur kroppsligt samspel uttrycks, uppstår, fortskrider och avslutas i förskolebarns fria inomhuslek samt miljöns och materialets betydelse för detta. För att kunna besvara våra frågeställningar i studien har vi genomfört videoobservationer och fältanteckningar vid två förskolor. Resultatet visar att kroppsligt samspel uttrycks, uppstår, fortskrider och avslutas på många olika sätt. Miljön och materialet har stor betydelse för det kroppsliga samspelet. Vi menar att miljöns utformning och utbudet av material vid sekvenserna har möjliggjort för barnen att mötas i olika lekar.

Energiförbättrande åtgärder på befintliga flerbostadshus : -En lönsamhetsanalys
The EU Council adopted in 2007, environmental and energy goals with the aim of them must be met by 2050. This, in combination with those of the Swedish government 15 enacted environmental goals is supposed to lead the way for the Swedish environmental work.This report has examined measures in properties in the Swedish Cooperative Housing Society (SKB) stocks.The report discusses a range of measures that might be appropriate to apply on the properties to make them more energy efficient.One of the measures discussed, the vent whose primary purpose is to create a good indoor environment for the residents but is also where the most energy is lost.Another measure discussed is insulation of the building envelope on the estate to make it more energy efficient. To put extra insulation on the building envelope is important because of the large amount of energy that is lost through the walls, ceilings and floors.Future actions that may be implemented is individual billing of heating and hot water. This system has been used in European countries since the 70's and today the EU wants to increase the own individuals control over their electricity costs. This has led to a discussion whether to implement the system in Sweden or not.However, there are a number of equitable measures to be sorted out before the system can be used in any great scale.Finally, it is important to remember that environmental measures should be the primary and the pursuit of cost reductions the secondary otherwise you risk the environmental work to be counterproductive..
