The 38th AIVC conference "Ventilating healthy low-energy buildings" was held on 13 and 14 September 2017 in Nottingham (UK). It was also the 6th TightVent conference and the 4th venticool conference.

Conference Scope

The need to reduce the energy demand of buildings is reflected in the legislation and policies of many countries. However, there is increasing concern about their adverse effects on occupant health and comfort in low energy buildings. These issues are being considered by some international energy conservation policy initiatives for buildings that seek to simultaneously reduce energy demand and provide acceptable indoor environment quality.

The minimisation of health risks and preservation of thermal comfort require the careful design and implementation of ventilation strategies and systems. There are many factors that must be addressed to achieve this goal, such as limiting occupant exposure to indoor and outdoor pollution sources, determining metrics capable of assessing indoor air quality, identifying factors causing overheating, and increasing envelope and ductwork airtightness.

It is this context that defined the core theme of the joint 38th AIVC, 6th TightVent and 4th venticool Conference as “Ventilating healthy low-energy buildings”. It placed its focus on:

thermal comfort and ventilative cooling (the application of ventilation to cool indoor spaces and reduce overheating risk in buildings);
air infiltration through cracks in the building envelope and ductwork;
the relationships between ventilation, indoor air quality and health.

Conference concept

The conference consisted of 3 parallel tracks largely devoted to:

ventilative cooling;
airtightness issues;
ventilation in relation to IAQ and health.

The conference consisted of a mixture of:

Well‐prepared and structured sessions focused on the conference topics;
Presentations on invitation;
Presentations arising from the call for papers.
