To understand exactly how we can ventilate buildings in the best possible way for
- occupants' well-being, and
- companies' productivity, and
- our environmental impact
we must make real progress in the following areas...
- Understanding how to take predictions of the local weather and estimate the forcing felt at the scale of an individual buildings,
- Understanding how to optimise the division of the geometry of a building into compartments in which the indoor environment can be considered to act as a whole,
- Understanding how, what and where to monitor within the building to accurately reflect the indoor environment to in terms of ventilation rates, thermal comfort and air quality,
- Understanding the response within a room to complex thermal forcing (such as multiple sources, temporal variation, distributed input and differential input, e.g. thermal radiation), for example understanding the stratification that is developed within the room, the mixing induced and the associated energy budgets,
- Developing low-order models that account for changes in the nature, location and scale of heat loads, and also suitably parametrise small-scale effects whilst enabling coupling between the flows through different rooms/compartments within a building,
- Implementing probabilistic approaches to suitably reflect uncertainties inherent in predictions, for example in predictions of the forcing due to the weather and variability of occupancy behaviour.
