Pre-1919 suspended timber ground floors in the UK: estimating in-situ U-values and heat loss reduction potential of interventions
Sofie Pelsmakers, UCL
This PhD thesis focuses on testing floor heat-flow theory and testing and refining measuring methods, practices and analysis techniques for uninsulated and insulated floors. Additionally, this research adds original knowledge about uninsulated suspended timber ground floor heat-flow and what the impact of insulating such floors might be, leading to research outcomes that are relevant to industry practice, policy and academia. In particular it aims to answer the following research questions:
- How should in-situ suspended timber ground floor U-values be estimated?
- What is the estimated in-situ thermal transmittance of floors and how does it compare to models?
- How does the in-situ thermal performance of a case study floor change after intervention measures?
The purpose of this PhD research is to test and construct knowledge and understanding of suspended timber ground floor heat-flow and how to measure this heat-flow. The research objectives are three-fold:
- To test, refine and develop research design and analysis methods to estimate the in-situ measured U-value of floors.
- To quantify the in-situ thermal transmittance of some existing floor constructions.
- To quantify the in-situ heat loss reduction potential and thermal comfort implications of some floor interventions.
