This 5th webinar introduced and demonstrated the definition of indoor climate and other health related indoor conditions requirements as set out in one of the EPB standards, EN 16798-1. In particular, it showed the thermal comfort requirements and how they can be evaluated by the calculation methods defined in the EPB standards. As a follow-up to the 4th webinar, it showed further applications and possibilities of an hourly calculation method beyond the energy needs calculation.

Following the successful previous webinars

In the frame of climate change, the overheating issue is getting more and more important for both health and productivity reasons, and strategies to avoid this by enhanced ventilative cooling need to be evaluated. The possibilities and limitations of such evaluations, using the methods described in the EPB standards and documents are shown, and further developments currently underway in standardization are introduced.
