Attendees of the CIBSE Building Simulation Group 2019 Annual General Meeting had the chance to sit through the technical presentations of the group's chairman Darren Woolf followed by a lively discussion.
The first presentation 'How flow can you go' drew from Darren Woolf's talk at The Future Envelope 12, Building Envelope Conference.
Five case- studies were presented on:
- Wind pressure simulation
- Pressure loss calculations (effective areas & discharge coefficients) and resulting flows
- Heat flow through complex glazing systems
- Glass temperatures impact on room air flow
- Multiple phases of heat transfer and condensation risk
Challenges very often presented to dynamic thermal modellers when modelling for natural ventilation were presented and links to CFD studies especially relevant to designing for performance.
The second presentation focused on ground heat transfer, the limitations and potential misalignment of ground heat transfer/U-value calculations and dynamic thermal models. Comparisons of the heating energy predicted by DTM and a co-heating test for a case study were also presented and discussed later on.
