  1. 1. Comparison of a hybrid ventilation system and a mechanical ventilation system with heat recovery through life cycle assessment : A case study of a modern Danish office building

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Josefine Nilsson Willkomm; [2020]
    Keywords : life cycle assessment; ventilation system; environmental impact; hybrid ventilation system; mechanical ventilation system with heat recovery; livscykelanalys; ventilationssystem; miljöpåverkan; ventilation; hybrid ventilationssystem; mekaniskt ventilationssystem med värmeåtervinning;

    Abstract : The building sector is responsible for 36% of the energy usage and 39 % of all CO2- emissions in European union (EU). Therefore, it is of great interest to investigate how the building sector can become more energy efficient and lower the environmental impact. READ MORE

  2. 2. A hybrid low - temperature heating system in geothermal retrofitting for public buildings in the Mediterranean climate

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Boumediene Bizimana; [2019]
    Keywords : Hybrid low-temperature floor heating; Energy performance; Thermal comfort; Indoor air quality; Lågtemperaturgolvvärme; Energiprestanda; Termisk komfort; Inomhusluftkvalitet;

    Abstract : More than 50 % of EU’s yearly energy demand is spent on heating and cooling systems with which most of its source is generated from non-renewable fossil fuel [1]. Furthermore, half of the EU buildings are heated with a non-efficient boiler of about 60% or less efficiency [1]. READ MORE

  4. 4. Engineered wood glass combination : Innovative glazing façade system

    University essay from KTH/Byggnadsmaterial

    Author : Alessandra Tapparo; [2017]
    Keywords : wood; glass; combination; engineered products; EWGC; façade; panel; sustainability;

    Abstract : Buildings require a lot of energy during all their lifetime, from the construction site to the use and demolition. The building sector contributes to a large part of the total emissions of greenhouse gases and consume a large amount of water and energy resources, so the material components used in the building sector have gained an important role in the discourse of sustainability.

  5. 5. Modeling and Optimization of Energy Utilization of Air Ventilation System of an Auditorium

    University essay from Högskolan i Gävle/Energisystem

    Author : Kappina Kasturige Kamani Sylva; [2016]
    Keywords : Hybrid Ventilation; CFD modeling; Auditorium;

    Abstract : Maintaining IAQ (Internal Air Quality) and thermal comfort of occupants in buildings have been a challenge to overcome satisfying the two ends: criteria for sustainability and cost effectiveness. Although there was a movement for mechanical ventilation systems in the recent past, in addition to the cost involved, they are found to not deliver the desired air quality, lead to social consequences such as sick building syndrome, contribute to environmental consequences related to ozone-depleting substances with increasing energy consumption, generate noise and having difficulties in cleaning and maintaining.
