WELL Prepared –En undersökning av hur ett byggnadsprojekt påverkas av WELL Building Standard

Gustlin, Pernilla, Skansholm, Erik January 2019 (has links)
Intresset för hur byggnader påverkar miljö och hälsa växer och en följd av detta har blivit att marknaden för certifieringar har ökat. En ny hälsocertifiering som kommit in på marknaden är Well Building Standard som fokuserar på hur byggnader och dess interiör påverkar människors hälsa och välbefinnande.Att vara först ut med att genomföra en ny certifiering innebär att det initialt finns begränsad kunskap om vad som krävs för att ett projekt ska uppfylla de ställda kraven. Syftet med examensarbetet har varit att sammanställa erfarenheter som aktörerna i WELL-projekten Eminent och Epic gjort, så att dessa kan användas som stöd vid planering av kommande projekt. Undersökningen utformades som en fallstudie av de två första kontorsprojekten i Sverige som genomför en WELL-certifiering på Core and Shell nivå. Som metod för insamlande av empiriska data valdes semistrukturerade kvalitativa intervjuer med nyckelpersoner kopplade till WELL-processen. Även en litteraturstudier gjordes tidigt för att formulera arbetets frågeställning och metodval för den empiriska informationsinsamlingen.I teoriavsnittet beskrivs WELL-certifieringens utformning, nyckelrollerna inom certifieringen samt hur certifieringen implementeras i arbetsprocessen. Därtill görs en sammanställning av teorier inom byggprocessen som berörts vid de genomförda intervjuerna. I projekten som ingår i studien har man lagt mycket tid på arbete som är kopplat till att översätta krav och verifiera material och produkter. Detta är i många fall engångsinsatser som kommer framtida projekt tillgodo. Arbetet har visat att det är viktigt att tydliggöra WELL-certifieringens innebörd i framtida projekt då certifieringsmetoden ännu är ny och okänd för många. Beställaren bör redan vid anbudsprocessen lägga grunden för ett visionsburet arbetssätt, samtidigt som entreprenören önskar ett tydligt och avgränsat ansvarsområde. För att lyckas med en WELL-certifiering är det viktigt att även yrkesarbetare och underentreprenörer görs delaktiga i WELL-visionen. / The WELL Building Standard is a new building certification which focuses on the long term effects on health and wellbeing. The aim of this study was to put together useful observations from the certification process in the first two Swedish office buildings, Eminent and Epic, which have worked with WELL Building Standard v1, Core and Shell. This project is a case study where information has been collected through qualitative interviews with key players in the certification process and through a literature study about WELL, project management and Building Information Modelling. The fact that WELL is new and that the criteria are based on American building standards has caused a lot of work in the projects. A lot of time was spent translating and verifying features. This is however something that will decrease in future projects.If the owner is committed and gives priority to integrated process and working with the visions of the healthy building, working with WELL can encourage the project members to be innovative in creating solutions which have positive long term health effects. The challenge is to do this in traditional project organizations where actors have short time commitments and demand distinct delimitations for their assignments.

Implementering av NollCO2-certifiering : En fallstudie av en nybyggnation för att identifiera hur netto-noll balans kan uppnås / Implementaion of NollCO2-certification : A case study of a new construction to identify how net-zero balance can be reached

Bjellerup, Victoria, Bäckström, Lisa January 2022 (has links)
This project aims to examine the demands of the new NollCO2-certification from a practicalpoint of view and to identify what it would mean for a real estate company to certify newconstructions according to NollCO2. Through investigation of a case-study object, a newbuilding at ICA Fastigheter, both climate impact and possible climate compensation measuresare analyzed in order to investigate how net-zero balance can be reached by 2045. By executing life cycle assessments and sensitivity analyses, both performed using MicrosoftExcel, the carbon footprint of the case-study building is evaluated within the NollCO2-certification framework. The project examines climate compensation measures related to bothenergy efficiency measures, and grid delivered renewable electricity. In the investigation,climate compensation measures are put in relation to both the NollCO2-framwork and ongoingsustainability work at ICA Fastigheter. The results show that there are many possibilities to decrease a building’s carbon footprint. Thegreatest decrease is retrieved by choosing materials with less carbon emissions such as greenconcrete or fiberglass insulation. In comparison to the case-study building’s original 512 tonsCO2eq, effective energy usage supplied from a green energy source can reduce the climateimpact further to approximately 415 tons CO2eq. To reach net-zero balance, offsite energyproduction can be installed. A solar park would need to produce 505 – 657 MWh which woulddemand approximately 15 000 - 20 000 square meters and cost 3.8 – 4.7 million Swedishcrowns. If ICA Fastigheter instead chooses to invest in wind power, the energy productionneeded would be 486 – 634 MWh, approximately 3% of the total production of an averagewindmill in Sweden. By investing in efficiency measures in existing buildings net-zero balancewould be reached with the expected expenses being a minimum of 7.6 million Swedish crowns. When analyzing the result of this case-study it is evident that an implementation of the NollCO2-certification is possible for ICA Fastigheter. However as of now, there are too many estimatesfor the result to be reliable. When taking ICA Fastigheter’s current long-term plans into accountit is evident that the most suitable climate compensation measure is to develop their energyefficiency projects in existing buildings. Efforts to increase energy efficiency in the real estateportfolio currently has a functioning workflow but must be improved to work as a sufficientclimate compensation measure when the number of new constructions aiming for the NollCO2-certification increases.
