This paper investigates the performance and control of natural ventilation during the heating season in order to avoid occupant discomfort. The current study examined different window configurations under a wide range of external temperatures and wind speeds using a CFD simulation tool. The results showed that thermally comfortable indoor conditions could be achieved in a UK classroom when external temperatures are as low as 8°C using high-level openable windows. At lower external temperatures, occupants are predicted to be thermally dissatisfied due to localised discomfort caused by draughts. The results from the CFD model also suggest that acceptable internal thermal conditions can be maintained with wind speeds up to 10m/s, for an external temperature of 10°C. The PMV results indicated that thermal comfort is achieved and is uniformly distributed within the classroom. This work will enable the UK's Education Funding Agency to have a greater understanding of the effective control of windows to eliminate wintertime discomfort and avoid unnecessary heating for naturally ventilated spaces.

The effect of climate change is increasingly manifested through more frequent and more intense extreme weather events, including heat waves and flooding. This briefing demonstrates how internal temperatures in housing can be reduced during a heat wave period purely by passive means.
Extreme weather events, including heat waves, are predicted to increase in both frequency and severity over the coming decades. Low rates of house building and a growing population mean there is a need to plan for climate adaptation of... more
Extreme weather events, including heat waves, are predicted to increase in both frequency and severity over the coming decades. Low rates of house building and a growing population mean there is a need to plan for climate adaptation of existing dwellings. This research uses dynamic thermal simulation to model the effect of a series of passive heat wave mitigating interventions for UK dwellings. The interventions include a range of additions and modifications to solar shading, insulation and ventilation.
Abstract The effects of selected passive heat wave mitigating interventions were modelled for 19 th century terraced houses in the UK, using two different occupancy profiles: a family and an elderly couple. Computer simulation, using... more
Abstract The effects of selected passive heat wave mitigating interventions were modelled for 19 th century terraced houses in the UK, using two different occupancy profiles: a family and an elderly couple. Computer simulation, using multi-zone dynamic thermal simulation linked to a nodal airflow model, was used to assess and rank the effectiveness of the interventions for reducing overheating during a heat wave period.

Climate change projections indicate that the UK is expected to experience more frequent and more intense heat wave periods over the coming decades. Buildings frequently experience overheating even under the present climate, resulting in discomfort, health complaints and even mortality. Current house building rates are low, resulting in a need to adapt the existing building stock to provide more comfortable and safe environments.

Multi-zone dynamic thermal simulation linked to a nodal airflow model, was used to assess and rank the effectiveness of selected passive heat wave mitigating interventions for reducing overheating during a heat wave period. The simulations were carried out for Victorian terraced houses in South East England using two different occupancy profiles: a family and an elderly couple and two different building orientations: front north facing and south facing.
