  1. 1. Värmetröghet i byggnader : En studie som undersöker en skolbyggnad utifrån olika materials värmetröghet samt dess klimatpåverkan genom en livscykelanalys

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Kerstin Axelsson; [2022]
    Nyckelord :värmetröghet; LCA; byggnadsmaterial;

    Sammanfattning : Thermal inertia is defined as “a measure of the responsiveness of a material to variations in temperature”. This means that materials with high thermal inertia will show small changes in temperature during a cycle of time and vice versa. LÄS MER

  3. 2. A techno-economic case study of external timber wall assemblies in Swedish single-family homes

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Deaa Maad; Mohamad Feras Alkhen; [2021]
    Nyckelord :IsoTimber; cross-laminated timber CLT ; timber frame; energy performance; wall construction; IDA ICE; heating demand; life cycle cost; massive wood; energy demand; heat capacity; one-story single-family house; two-story single-family house.;

    Sammanfattning : Decisions made at the early stage of building design can significantly influence theenvironmental, energy and economic performance of buildings. Future homeowners anddevelopers often have to make decisions concerning the design and specification of thebuilding. LÄS MER

  4. 3. Free cooling in data centers : Experimental test of direct airside economization with direct evaporative cooling

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Rickard Liikamaa; [2019]
    Nyckelord :Data center; free cooling; evaporative cooling;

    Sammanfattning : The backbone of the expanding Information and Communication Technology (ICT)-sector are data centers. In these, Information Technology (IT) equipment is housed which provides computational power for e.g. cloud computing and internet services. LÄS MER

  5. 4. Processes of lateral moraine formation at a debris-covered glacier, Suldenferner (Vedretta di Solda), Italy

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Monika Rabanser; [2019]
    Nyckelord :Lateral moraines; Moraine genesis; Moraine stability; Debris-covered glaciers; Clast shape; Alps; Sedimentology; Glacier fluctuations; Earth and Environmental Sciences;

    Sammanfattning : Lateral moraines are key features of glacial landscapes in high-alpine mountain areas. Research on lateral moraine formation is mostly limited to clean-ice glaciers; lateral moraine formation at the margins of debris-covered glaciers is currently poorly understood in an Alpine and sedimentological context.

  7. 5. Alternative methods to prevent thermal cracking in concrete

    M1-uppsats,

    Författare :Alexander Barchin; Navid Sedighi; [2019]
    Nyckelord :Massive concrete structures; heat development; cement hydration; temperature reduction; cracking; fly ash; ice; coarse aggregates; cooling methods; practical tests.; Massiva betongkonstruktioner; värmeutveckling; cementhydrataion; temperaturreducering; sprickbildning; flygaska; is; grov ballast; kylningsmetoder praktiska försök.;

    Sammanfattning : In the construction industry, concrete is the most common material, because of its good properties such as compressive strength and endurance. Concrete is a composition of several different materials where one of the main components is cement. When the hydration process starts, large amount of heat is generated. LÄS MER
