WD1 Review of domestic water system sizing

10:00 - 11:15
22/11/2017

We know that there is now growing concern within the public health engineering sector that the traditional loading unit method used in the UK for the estimation of simultaneous design flows and water demand for hot and cold water supply systems within buildings results in the oversizing of pipe systems and booster pumps. In this session, we will explain the work of the LUNA (Loading Unit Normalisation Assessment) project; a Knowledge Transfer Partnership (KTP) between Heriot-Watt University and the Chartered Institution of Building Services Engineers (CIBSE). The overall aim of this project is to shift current practice from a reliance on a probability based framework and instead adopt an empirically defined algorithm that is compliant with current practices and technologies.

This session will discuss:

  • Why change is needed
  • What the evidence for this is
  • How, where and when we will collect data
  • How we intend developing the new algorithm
  • How this will be validated and tested for ‘usability’
