LoginIn 2017, the Air Infiltration and Ventilation Centre (AIVC) identified smart ventilation for buildings as a new and important topic to be addressed.
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.
Natural and Hybrid ventilation systems, by using exclusively or partially natural driving forces, help to reconcile building energy sobriety and good Indoor Air Quality (IAQ).
The 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.
In order to better address energy and indoor air quality issues, ventilation needs to become smarter.
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.
Using natural ventilation is effective to save energy, and it is essential for energy conservation and decreasing running cost [1].
Amid the contaminant issues, air pollution has awakened more interest due to its potential health risk and its direct effect on human productivity.
The “VIA-Qualité” project (2013-2016) aims at developing quality management (QM) approaches (ISO 9001) on ventilation and indoor air quality (IAQ), for low-energy, single-family buildings.
One of the main factors influencing building airtightness is the construction typology.
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:
The increasing weight of building leakages energy impact on the overall energy performance of low-energy buildings led to a better understanding of the actual airtightness performance of buildings.
Because of the need of energy conservation and Business Continuity Planning (BCP), natural ventilation system, which basically does not use non-renewable energy, is attracting academic/practical attention.
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.
The implementation of the Energy Performance of Buildings Directive 2010/31/EU recast puts increasing pressure to achieve better building and ductwork airtightness.
The opening keynote will present an overview of the current status and future opportunities for smart buildings in Europe, in the context of the transition to more sustainable use of energy.
In France, the new Promevent protocol for ventilation system inspection in new dwellings has been published in 2017.
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.
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
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.
