Ventilative Cooling Design In Practice: Where next?

Embedding robust yet accessible frameworks to evaluate ventilative cooling potential during the early/concept design stages for building practitioners can help in reducing the performance gap as well as avoiding vulnerability “lock-in” from design decisions that are based on poor or inadequate information. The challenge is to develop performance based evaluation methods that recognise the tacit approach to design in practice. Often design is iterative, non-linear and multi-agent.

Update on Resilient cooling and indicators from the IEA EBC Annex 80

The growing challenges of climate change, urbanization, and increased energy demand have underscored the critical need for sustainable and resilient cooling solutions in buildings. In response to this pressing global issue, the International Energy Agency's Energy in Buildings and Communities (IEA EBC) Annex 80 was initiated to address the multifaceted aspects of resilient cooling in the built environment. Annex 80 seeks to provide valuable insights into resilient cooling systems and their indicators, offering a pathway towards a more sustainable and adaptable future...

Importance of thermal stack effect in ventilative cooling concepts for residential buildings

This paper investigates the impact of ventilative cooling in residential buildings constructed from light-weight cross-laminated timber. Different temperature-controlled ventilative cooling concepts such as single sided ventilation, cross-ventilation and thermal stack based chimney ventilation concepts are simulated and compared in terms of impact on indoor temperature and robustness to external conditions such as the surroundings and the building orientation.

Renewable ventilative cooling? Insights from an Irish perspective

The future needs of indoor spaces in our buildings are likely to be cooling focused. With the widespread use of air-conditioning (AC) on the horizon there is now a need to ensure our systems perform as renewables (under the relevant definitions). A key part of tackling the uptake in energy intensive AC is likely to be the balancing of AC with renewable natural and mechanical ventilative cooling (VC).
