346 - Extensive sensitivity analysis of diverse ventilation cooling techniques for a typical administrative building in Mid-European climate

摘要

Objective of this study is to compare the cooling potential of diverse passive cooling techniques linked to ventilation: controlled thermal phase-shifting (a recently discovered phenomenon), air-soil heat exchangers, evaporative cooling, and direct night cooling. The potential of these techniques is investigated for the case of an administrative building located in a moderate climate, with a specific attention to urban versus rural location, as well as normal versus extreme summer (of type 2003). Simulated building response is analyzed for a variety of constructive and operational configurations (solar protection, thermal mass and insulation, internal gains), in free floating mode as well as with auxiliary cooling backup.
