1. Computational Analysis of Spray Deflector Designs
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. LÄS MER
2. 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
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : 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. LÄS MER
3. A hybrid low - temperature heating system in geothermal retrofitting for public buildings in the Mediterranean climate
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : 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]. LÄS MER

5. Likströmsnät i byggnader : En genomförbarhetsstudie för ett potentiellt smartare och energieffektivare elsystem
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : Byggnaders interna distributionsnät är idag liksom resten av elnätet sedan länge växelströmsbaserat. Idag använder dock det mesta i en byggnad likström vid slutanvändningen. Dessutom ökar användningen av solceller, batterilager och elbilar snabbt och alla dessa bygger också på likström. LÄS MER
