The state-of-the-art (SOTAR) report of ECB Annex 62 Ventilative Cooling is completed; it summarises the work of the initial working phase of the Annex and is structured in five chapters:

Potentials and limitations, reviews existing methods suitable to estimate the cooling potential of climatic conditions considering  building characteristics, outlines critical barriers to ventilative cooling and reviews thermal comfort indices.

Ventilative cooling in existing Energy Performance Regulations, presents results of surveys through questionnaires on the treatment of ventilative cooling in national codes and standards.

Exemplary Existing Building using Ventilative Cooling, presents twenty-six existing and operational buildings using principles of ventilative cooling.  All buildings were built after 2000, are located in different climates and are of a variety of building types.

Existing Components and Control Strategies for Ventilative Cooling, presents ventilation components, classified into guiding, enhancing and cooling, and actuators and sensors; illustrated with photographs of existing components in the market and/or as installed in operational buildings.

Existing Methods and Tools suitable for designing ventilative cooling aspects during building design are reviewed.  A table with commonly used public domain and commercial models together with some details of inputs and outputs required is given.

The review reveals that ventilative cooling is an attractive option for the reduction of energy use in residential and non-domestic buildings with materialised examples in a variety of climates.  As a cooling strategy has the potential to contribute significantly to the reduction of the end use cooling energy demand.  The review also reveals that in many national building codes and energy performance regulations ventilative cooling is not explicitly refer to as a cooling option.  Therefore the treatment of ventilation requirements for cooling and its effect on cooling demand reduction are not clear. This has an impact on the architectural design as well as the specification of components and controls.
