DESCRIPTION OF THE SESSION

Join us for an insightful session as we delve into the latest breakthroughs for overheating mitigation using ventilative cooling and cutting-edge findings from new projects. In this dynamic session, experts from various disciplines will converge to explore the impact, applications, and advancements in how to design ventilative cooling systems in upcoming standards, while also leaving good time for discussions in the latter part of the session.

The purpose of this session is to:

1. Give an overview of how ventilative cooling fits in the standardisation world. What are the gaps and how can it fit in future European standards.
2. Give examples on how to apply the design route in the upcoming ventilative cooling standard for your next project. We will go through the various design steps in the standard and explain the rationale behind these. These should secure a robust and resilient VC design.
3. Highlight the differences between the theoretical predictions using the VC potential method/tool versus data from a case study. This will enlighten the participants and make them aware of the potential of the method, and more importantly, become aware of its limitations.
4. Have an interactive discussion on the design paths to secure an optimal VC design and receive input from the audience on subjects to be included in these design paths.

OBJECTIVES OF THE SESSION

The objective of this session is to provide participants with a comprehensive understanding of the latest developments in ventilative cooling evolutions, while also having time to contemplate on relevant questions.

At the session we wish to further highlight the “hidden” features of how to actually design and calculate on overheating mitigation using ventilative cooling. Not all are aware that there exists good upcoming standards and tools that can highlight the potential of ventilative cooling in the early design stage. Hence, the main purpose is to explain a variable way to design a VC system including a feasibility path including a newly developed “VC potential method/tool”. This VC method offers a quick evaluation of the VC potential for the specific building location. To fully understand the VC method a case study will be provided to give an insight in the difference between the predicted values using the method versus the measured in the case study. 

Lastly, we want to include the audience in an interactive way by having a discussion on “how to ensure a good and resilient VC system design” and the findings should be included the current VC design path in this work. 

Therefore, we wish to:

• Present the latest standardization projects on ventilative cooling and expected outcomes and how it fits in the future European standardisation.
• Go through the VC design steps on how to design a proper ventilative cooling system including a case study example.
• Facilitate a discussion to get the feedback on the VC design steps and what is missing or who to optimise the path.
