  • Impact of Clothing and Activity Level on Energy Consumption and Thermal Comfort on The Occupants in The Residential Building in Cold climate Region
    (2014) Alam, Sadaf
     School of Engineering | A4 Artikkeli konferenssijulkaisussa
    In this paper, various clothing level and metabolic rates have been simulated andanalyzed to study the impact on the thermal comfort and energy efficiency of thedetached house in cold climate region Finland.The main objective of this paper is to show how much minimum and maximumindoor air temperature can be achieved while fulfilling the target values for thermalconditions selected and defined according to SFS-EN—15251. PMV and PPD havebeen calculated in order to show the satisfaction crieterias.
  • Towards Net Zero Energy Buildings: building performance optimization, simulation and analysis
    (2019) Alam, Sadaf; Lahdelma, Risto
     School of Engineering | A4 Artikkeli konferenssijulkaisussa
    The European Union 2020 energy targets seems to be a progressive, however, it still needs to be worked upon. The implementation of Nearly Zero Energy Buildings (nZEBs) as the building target represents one of the biggest challenges to increase energy savings and minimize greenhouse gas emissions. In this paper detached house has been modelled using dynamic simulation tool and the energy efficiency measures, concerning different technologies for envelope systems and technical systems, were set up as parameters in dynamic simulation tool and simulated and analysed. The objective of this paper is to define the heating, cooling, and electricity demand of a residential building in a cold climate region. The façade parameters were optimized for the best possible energy performance, to be used as design guidelines for facades in low and nearly zero energy buildings for architects and engineers. The purpose of the study is to give guidelines of office buildings facade design from the perspective of energy-efficiency and daylighting to architects, engineers, real-estate developers, etc.
