A smart ventilation system is able to continually adjust itself to provide the desired IAQ while minimizing energy use, utility bills, thermal discomfort and noise. A smart ventilation system is also responsive to e.g., occupancy, outdoor conditions, and can provide information about e.g., IAQ, energy use and the need for maintenance or repair.
The evaluation questionnaire of the 43rd AIVC conference: “Ventilation, IEQ & health in sustainable buildings” was sent out to 200 attendees of the event. 98 participants filled in the evaluation form. We are happy to share with you a summary of the main results!

AIVC's Ventilation Information Paper #47 gives guidance to perform a pressurization test in high-rise buildings and suggests new criteria to replace standard requirements when they cannot be met.
A special issue of Buildings (ISSN 2075-5309) is now open for submission.
This Special Issue is motivated by the importance of the airtightness of buildings in terms of indoor air quality and the energy implications of heat transfer. Currently, it is not possible to design and construct nZEB buildings without taking this parameter into account, and it is essential that we can determine this parameter in buildings to be renovated in order to achieve a significant improvement in their final energy consumption.
The date for the AIVC -TightVent - venticool 2023 Conference: “Ventilation, IEQ and health in sustainable buildings” is now approaching quickly! The conference will be held during 4-5 October 2023 in Copenhagen, Denmark.
More than 190 people have booked their seats for the event!
The event will open with a welcome reception on Tuesday October 3, 2023 at 19:00.
The conference will start on Wednesday October 4, 2023 at 09:00. On-site registration will be open from 08:00.
The AIVC is happy to announce the release of a new publication!
AIVC's Ventilation Information Paper #46: Building airtightness impact on Energy Performance (EP) calculations aims to explain simplified models developed and used around the world to estimate the infiltration rate for Energy Performance (EP) calculations and give some examples of methodologies applied in various countries.

Many simplified models have been developed and are used around the world to estimate the infiltration rate for Energy Performance (EP) calculations, with different levels of accuracy, as described below. For example, the wind velocity can be estimated hourly, monthly or annually; based on the local climate or fixed estimated values; with or without taking into account shielding factors; etc.
AIVC's Ventilation Information Paper #46 aims to explain these simplified models and give some examples of methodologies applied in various countries.
