Energianalys mellan programmen IES (Integrated Environmental Solutions) och Enorm

An increase interest of new methods and tools has begun to grow in the real estate business, this new trend causes an increase in new programs that aim to simplify processes of energy-efficiency and environmental issues.After consulting with Björn Alsmark from Bjerking AB, an architect and engineering company, we made a decision that the Degree Project is going to examine the program IES (Integrated Environmental Solutions) with some integrations from Revit Architecture application.To be able to examine IES, we got access to a completed project from Bjerking. The project is a nursery school in Uppsala. An application has been handed in from Bjerking to make this project to a Green Building-certificated project. According to Bjerking own calculations (with the energy-calculation program Enorm), the consumption of energy of the nursery school is 48 percent lesser than required by BBR.An evaluation of IES and Enorm has been made with an aim to compare these two programs and find out if IES is an appropriate program to replace Enorm. Does Enorm or IES come up to BBR´s recommendations?The Degree Project cover 15 ECT, that required several adjusting and delimitations, and the study sketch ended with a literature study.After finishing the study sketch the modeling of the nursery school began.

Green Building : Ett företags energieffektiviseringsarbete i ett byggprojekt samt de krav som ställs för att få byggnaden Green Building klassad.

The examination has been performed at Bjerking AB, which is an architectural and engineering company. Bjerking AB has the ambition to be a member of Green Building.The Green Building program developed in year 2005 by The European Commission, the program is an environmental system with the aim to improving energy efficiency within the sectors of non-residential buildings. The minimum requirements to participate the program are following: in new-built buildings the calculated energy consumption must be 25 % lower than the requirements in the BBR (Building regulations) and in refurbishment the reduction must be 25 % lower than before the optimization.The aim of this study has been to examine and review the company Bjerking AB's energy efficiency work in the project of building the school/kindergarten S:ta Maria Alsike, where the goal is to get this building Green Building classed. A description of requirements to become a member of the Green Building has also accomplished in the thesis.The methods performed in this study are literature review, searches on the Internet, studies on the project database for facts/values, calculation of energy consumption and interviews of members of the Green Building. The following issues have been dealt with in the report;-          Did the building in the project manage the requirement to achieve an   energy consumption that is 25% lower than the requirements in BBR?-          What technical measures/system was selected in the building?-          What kind of cooperation was the project based on?-          What is required for consultancy companies and real estate owners to become members of the Green Building?The study of the project and calculation of estimated energy consumption in the building, give the result 47 kWh/m2, year.

Kommunikations- besluts- och informationsflöden i byggprocessen

Construction projects are organized in different shapes and disturbances in the information flow in these processes can lead to problems, such as delays and/or a lower quality. Therefore, a well-functioning interaction between actors and a well thought out-communication at an early stage is of crucial importance. The main question is "How does the communication of decision and information flow in the building process and what barriers and opportunities can be observed?". This diploma work has been written with guidance from Bjerking AB and to answer this question, a collection of empirical data conducted via semi-structured interviews.

En jämförelse mellan TLS och UAV-fotogrammetri : Inmätning av hårdgjorda ytor

At present day there are several different methods for measuring of paved surfaces.The most common methods today are measuring with a total station, the GlobalNavigation Satellite System (GNSS) and terrestrial laser scanning (TLS). Recently thedevelopment of unmanned aerial vehicles, known as drones, has increasedexponentially and today there are several ways of using drones for measuring surfacesby photographing and laser scanning.This thesis contains a comparison between the methods terrestrial laser scanning(TLS), and unmanned aerial vehicle photogrammetry (UAV). The measurements havebeen applied on two different test surfaces, one of asphalt and one of gravel. Thepurpose of the comparison is to investigate whether the airborne photogrammetry isequivalent accurate in its height levels as the terrestrial laser scanning. For thecomparison to be more extensive, these two methods have not only been comparedin precision but also in the areas of ease of use and economy.The precision was analyzed by comparing the height levels in randomly placed controlpoints on the test surfaces.

Att skapa konserten; Melting, Forming

Som frilansande musiker, kompositör och bandledare vill Miranda Bjerking Raeder utforska hur en konsert kan bli en större upplevelse om man tillsätter bildkonst och dansare tillsammans med bandet Black Dough på en scen. Hon vill se hur scenuttrycket växer och får mer substans när det utmanas till att vara mer storslaget. Några av frågorna som hjälpte henne att starta sin resa är: Hur kan jag sammanföra musik, bildkost och dans utan att förvirra publiken? Varför är det viktigt för mig att göra en konsert av denna form? Vilka problem och kompromisser stötte jag på i projektet? ochVilka nya perspektiv och erfarenheter öppnade sig för mig under arbetets gång?.

Användbarheten av Tekla i Betongkonstruktioner : En jämförelsestudie mellan två modelleringsprogram

This thesis has examined the Tekla Structures modeling software and answered the question of whether it could act as a suitable modeling program for the design department at Bjerking AB in Uppsala. The method used in this work is a case study of a previous project with existing basis to work form. The demarcation of the study was to examine only the usability of the foundations of in situ concrete. The work examined three main areas within the design process. The first was to model the concrete elements then to model the reinforcing and ultimately production of the drawings. Because Autodesk Revit was the existing modeling program in the Department conducted the evaluation as a comparison between the two programs.

Hur kan kostnaden minskas för dörrmiljöer utan att försumma funktionen?

The door and its surrounding, is an important part of all buildings. It often amount to a significant part of buildings total costs. The more demands of functions the largerdoes the costs grow.The purpose of this report is to analyze those demands and how to fulfill them.Another purpose is to examine of which reasons the cost grow and how to avoid it inthe best possible way. The study will be performed in collaboration with Bjerking AB. To define the demands a literature study will also be performed.

Punktmolnshantering i anläggningsprojekt : Utvärdering av programvaror för framtagande av markmodell

An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.

LCC-analys av FTX-system : En jämförelse av centralt- och lägenhetsplacerat

This report is the result of a thesis conducted at the consulting firm Bjerking AB andis the final part of the Bachelor Programme in Construction Engineering at Universityof Uppsala. The work aims to investigate the costs and how the choice of ventilationsystem affects building projects during a long-term period. This report covers costssuch as investment, maintenance and energy but also how they affect residents andbuilders. Building regulations for energy consumption are expected to be tougher;therefore a comparison of two different heat recovery ventilation systems(HRV-system) was made. One system is based on a centrally placed unit that coversthe whole buildings ventilation through vertical shafts.

Inverkan av försvagningar på bärförmåga för stålbalkar med långa spännvidder : En jämförelse mellan Eurokod och BKR

The purpose of this thesis is to investigate the degree of influence of holes in the web of steel beams with long spanson weakening of their bearing capacity. Making holes in the web of the beam generally reduces the bearing capacity of the beam. However, it might be necessary seen from both an architectural perspective as well as from a building services perspective by creating an opportunity for building installations.The objective of this thesis is to examine how much an I-beam can be weakened without sacrificing safety and functionality. The investigation has been done by using Finite Element Method through commercial software.The regulation for structural design of building structures in Sweden used to be specified in the document known as BKR. But this was replaced by the European norm Eurocode back in May 2011.

Stabilisering av höga trähus via centralt placerat hisschakt

I Sverige finns det inte många höga trähus, trots den enorma tillgången på material och det faktum att de allra flesta villor/småhus är byggda av just trä. Att trä är ett lätt byggmaterial, är väl lämpat för prefabricering samt är återvinningsbart i stor utsträckning medför att det är väldigt konkurrenskraftigt. Så varför utnyttjas inte detta byggmaterial oftare? En av anledningarna till det ligger i de konservativa regelverk som tidigare funnits i Sverige, de har inte tillåtit att bygga högre än två våningar med bärande stomme av trä. Något som ändrades vid årsskiftet 93/94 då en ny norm, BBR 94, kom som gjorde det möjligt för trä att användas i stommar.
