Thermal Performance Of Pcm-Glazing Unit Under Moderate Climatic Conditions, Anna Wieprzkowicz, Dariusz Heim Sep 2018

Thermal Performance Of Pcm-Glazing Unit Under Moderate Climatic Conditions, Anna Wieprzkowicz, Dariusz Heim

International Building Physics Conference

Considering physical properties, transparent or translucent building components like windows or glazing facades are the weakest elements of building envelope. The heat transfer coefficient of such elements is approximately four times higher than for opaque partitions, which causes considerable increase of heat loss during winter. In summer relatively high solar transmittance is a source of heat gains which results in undesirable overheating. Application of phase change materials in glazing components affects its thermal performance by the increase of its heat capacity and decrease of solar heat gains, with regard to the current physical state of the PCM. The aim of ...


The Impact Of Ventilation Strategy On Overheating Resilience And Energy Performance Of Schools Against Climate Change: The Evidence From Two Uk Secondary Schools, Esfand Burman, Dejan Mumovic Sep 2018

The Impact Of Ventilation Strategy On Overheating Resilience And Energy Performance Of Schools Against Climate Change: The Evidence From Two Uk Secondary Schools, Esfand Burman, Dejan Mumovic

International Building Physics Conference

The indoor environmental quality and energy performance of two modern secondary schools in the UK which have fundamentally different environmental strategies were investigated during building performance evaluations. The performances of these buildings against the projected weather data for future were also analysed. The results point to significant risk of future overheating as a result of climate change in the naturally ventilated building with passive measures that go well beyond the existing guidelines for schools. The other school with mechanical ventilation shows resilience to future overheating. However, shortcomings in building procurement and operation have severely compromised its energy performance. It is ...


Empirical Assessment Of Summertime Overheating Risk In New, Retrofitted And Existing Uk Dwellings, Rajat Gupta, Matt Gregg, Robert Irving Sep 2018

Empirical Assessment Of Summertime Overheating Risk In New, Retrofitted And Existing Uk Dwellings, Rajat Gupta, Matt Gregg, Robert Irving

International Building Physics Conference

This paper statistically assesses the hourly internal summertime temperature datasets gathered during the summer of 2013 (May to September), from 63 dwellings across the UK. The sample consisted of unmodified dwellings (existing); dwellings with varying levels of fabric improvements (retrofitted) and dwellings constructed to higher levels of the Code for Sustainable Homes (new). Indoor and outdoor temperature data from bedrooms and living rooms from these homes were collected at five-minute intervals using temperature sensors. These data were processed and analysed for summertime overheating, using both static criteria (CIBSE Guide A) and the criteria associated with the EN15251 adaptive thermal comfort ...
