A multi-stage optimization method for cost-optimal and nearly-zero-energy building solutions in line with the EPBD-recast 2010
Hamdy, Mohamed (Journal article; Peer reviewed, 2013)Finding cost-optimal solutions towards nearly-zero-energy buildings (nZEBs) in accordance with European energy performance of buildings directive (EPBD-recast 2010) is a challenging task. It requires exploring a huge number ... -
Comparison of the Energy Saving Potential of Adaptive and Controllable Smart Windows: A State-of-the-Art Review and Simulation Studies of Thermochromic, Photochromic and Electrochromic Technologies
Tällberg, Kurt Inge Richard; Jelle, Bjørn Petter; Loonen, Roel; Gao, Tao; Hamdy, Mohamed (Journal article; Peer reviewed, 2019)Windows play a huge role in today’s buildings, allowing for outside view and providing occupants with daylight. However, windows are also often considered to be one of the weakest building components with respect to high ... -
Daylight requirements in the Norwegian Regulations vs. the European Standard: A case study considering thermal performance
Solvang, Helene (Master thesis, 2019)I denne masteroppgaven er Norsk Byggteknisk Forskrift TEK17 og den Europeiske Standarden for Dagslys FprEN17037 blitt sammenlignet med hensyn på dagslys, samt hvilke konsekvenser for termisk komfort og energibehov de ulike ... -
Effect Of Grid Tariffs On Demand-side Management In All-electric Buildings In Norway
Karlsen, Sophie Schønfeldt; Backe, Stian; Hamdy, Mohamed (Journal article, 2019)The increased share of inflexible, renewable energy sources in power systems is challenging the balancing of demand and supply. Rapid and unpredictable load variations might require large power grid capacities to ensure ... -
Multi-Objective Optimization of Building Energy Design to Reconcile Collective and Private Perspectives: CO2-eq vs. Discounted Payback Time
Hamdy, Mohamed; Mauro, Gerardo Maria (Journal article; Peer reviewed, 2017)Building energy design is a multi-objective optimization problem where collective and private perspectives conflict each other. For instance, whereas the collectivity pursues the minimization of environmental impact, the ... -
Sensitivity analysis for investigating the energy performance of a retrofitted kindergarten under different weather scenarios
Eggebø, Håkon (Master thesis, 2017)Sensitivity analysis is a technique that aims at estimating how the uncertainty in the independent variables of a mathematical model effects a particular dependent variable given a predefined set of assumptions. This method ... -
Strategies for Modelling Dynamic Parameters in Optimization-Based Building Energy Model Calibration: A Case Study
Haug, Karoline Bondø (Master thesis, 2019)Bygninger står for en høy andel av verdens energiforbruk. Selv om det stadig gjøres fremskritt når det kommer til innstramminger i energikrav for nye bygninger, er det samtidig viktig å undersøke kostnadseffektive løsninger ... -
The Impact of Insulation and HVAC Degradation on Overall Building Energy Performance: A Case Study
Eleftheriadis, Georgios; Hamdy, Mohamed (Journal article; Peer reviewed, 2018)Through monitoring of buildings, it can be proven that the performance of envelope elements and energy supply systems deteriorates with time. The results of this degradation are higher energy consumption and life cycle ... -
The impact of ventilative cooling technologies on heating energy and thermal comfort in residential buildings
Johansen, Vegard Skregelid (Master thesis, 2020)I løpet av de siste tiårene så har kravene for energiforbruk og termisk inneklima blitt stadig strengere. Samtidig har nye løsninger blitt introdusert som har potensiale til å løse problemer relatert til unødvendig ... -
Undersøkelse av ventilasjonsprinsipper for museer
Omli-Moe, Tonje Margrethe (Master thesis, 2019)Museer er institusjoner som skal ta vare på samlinger av gjenstander med historisk eller vitenskapelig verdi, samt kunstverk. Denne kunnskapen skal videreføres gjennom utstillinger tilgjengelig for offentligheten, og sikre ...
