LoginThe present talk will present some of the initiatives from ASHRAE regarding “smart” in general and then focus on indoor environmental activities related to “smart” ventilation.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
Energy performance of buildings has been continuously and systematically improved in Europe with next step of transition to nearly zero energy buildings (NZEB) in 2019-2021.
In order to better address energy and indoor air quality issues, ventilation needs to become smarter.
Indoor environment and indoor air quality (IAQ) are considered as subjects of major concern: as we build more and more energy efficient and airtight buildings, the conflicting issues of energy efficiency, adverse health effects and discomfort beco
The ClimACT project has been developed under the priority axis “Low Carbon Economy” of the Interreg SUDOE program. It aims to support the transition to a low carbon economy in schools.
Since January 1st, 2018, airtightness testing has become implicitly mandatory for every new residential building in Flanders. There is no minimum requirement for airtightness.
In this study, durability of building airtightness was assessed by means of repeated airtightness testing of the studied houses. This approach generally involves the following issues which complicate the comparison of the test results:
In France, the new Promevent protocol for ventilation system inspection in new dwellings has been published in 2017.
In-situ performance of mechanical humidity-based mechanical exhaust ventilation (RH-MEV) is characterized in this study.
The air leakage impact on energy performance in buildings has already been broadly studied in USA, Canada and most European countries. However, there is a lack of knowledge in Mediterranean countries regarding airtightness.
Norwegian building regulations refer to the NS-EN 15251 and the NS-ISO 7730 to define indoor climate criteria in new buildings. For example, the standards prescribe a temperature band of 20-26°C for a normal office situation.

Using natural ventilation is effective to save energy, and it is essential for energy conservation and decreasing running cost [1].
Over the course of the four-year research project of the IEA EBC Annex 62, Ventilative Cooling (VC) has been proven a robust and highly energy efficient solution to support summer comfort in both residential and commercial buildings.
In 2017, the Air Infiltration and Ventilation Centre (AIVC) identified smart ventilation for buildings as a new and important topic to be addressed.
This paper summarizes the most recent results of the French database of ductwork airtightness. This database was created in 2016. It is fed through measurements performed by qualified testers according to a national scheme regarding ductwork.
Drøbak Montessori lower secondary school is Norway’s first plus-energy school and also the first school built after the Norwegian Powerhouse-concept, www.powerhouse.no.
The French database of building airtightness has been fed by measurement performed by qualified testers since 2006.
One of the main factors influencing building airtightness is the construction typology.
Duct leakage airflow in existing ductwork can reach values of over 20% of the design air handling unit (AHU) airflow, undermining efficiency and effectiveness of HVAC systems.
