Ventilation is critical in interpreting indoor air quality (IAQ), yet few IAQ assessments report ventilation rates; even when they do, the measurement method is often not fully described.
39th AIVC - 7th TightVent - 5th venticool Conference - Antibes Juan-Les-Pins, France - 18-19 September 2018
The 39th AIVC Conference "Smart Ventilation for Buildings", was held in Antibes Juan-Les-Pins, France, 18-19 September 2018. Contains 140 papers and/or summaries.
Airflow measurements at supply air terminal devices on residential balanced ventilation systems | 2018 | English | 9 pp
In France, the control of ventilation system at commissioning is mandatory in the context of the Effinergie + label and the measurement of airflows in residential houses is mandatory since 2017 in this label.
Non-intrusive experimental assessment of air renovations in buildings and comparison to tracer gas measurements | 2018 | English | 9 pp
The work reported in this paper extends previous work on the feasibility to characterise air leakage and mechanical ventilation avoiding intrusiveness of traditional measurement techniques.
An extended pressure range comparison of the blower door and novel pulse method for measuring the airtightness of two outdoor chambers with different levels of airtightness | 2018 | English | 11 pp
The steady pressurisation method measures the building leakage in a range of high pressures, typically 10-60 Pa.
The air tightness of eight apartment buildings containing six to eleven units each on three or four floors has been tested with and without guard-zone pressure, i.e. with and without consideration of internal leakages.
A cost-effective and versatile sensor data platform for monitoring and analysis of building services | 2018 | English | 10 pp
Conventional building management systems are costly to install in existing buildings. Building services fail, which results in a cascade of incorrect responses, or occupants and administrators misuse systems.
Indoor air quality investigation in a ventilated demonstrator building via a smart sensor | 2018 | English | 10 pp
This study deals with ventilation effects on measured and perceived indoor air quality (IAQ) in a demonstrator building where IAQ problems can occur.
Over the past few years there have been advances in sensing of some pollutants, primarily particles, that might lead to ventilation controls based on direct sensing of pollutants – particularly those relating to health.
The difficulty in measuring IAQ indicators like VOCs and particles, lies in the multiplicity of the composition of these pollutants.
The different methods for air flow rate measurement at air terminal devices are presented in this overview, such as van anemometer with a cone, small velocity probe (thermal probe or small vane anemometer), compensation method, etc.
A review of European standards related to measurement at air terminal devices | 2018 | English | 5 pp
Two European standards EN 16211:2015 and EN 12599:2012 describe measurement methods for air flow. The methods can be used at supply or exhaust air terminal devices, ATDs, or in ducts.
Occupants in non-industrial indoor environments should decide whether the indoor air quality is acceptable or not.
Background and Objective of IEA-EBC Annex 78. Supplementing Ventilation with Gas-phase Air Cleaning, Implementation and Energy Implications | 2018 | English | 2 pp
The proposed Annex should bring researchers and industry together to investigate the possible energy benefits by using gas phase air cleaners (partial substitute for ventilation) and establish procedures for improving indoor air quality or reduced
This workshop session will consist of a series of presentations by members of the Board for the Indoor Environmental Quality – Global Alliance (IEQ-GA).
As one of the founding partners of the IEQ-GA, the networking with other organisations within the global alliance is for AIVC very important.
In these three presentations, we review the origins and history of the Indoor Environmental Quality Global Alliance, AIVC’s view of the potential value of IEQ-GA, and directions it is taking and may take over the next decade.
Temperature, draft and ventilation efficiency of room based decentralised heat recovery ventilation systems | 2018 | English | 6 pp
Mechanical ventilation systems with heat recovery are considered the most optimal systems for residential ventilation. This research focuses on decentralized ventilation which do not need any ducting.
Energy performance of demand controlled mechanical extract ventilation systems vs mechanical ventilation systems with heat recovery in operational conditions : Results of 12 months in situ-measurements at Kortrijk ECO-Life community | 2018 | English | 10 pp
In a recently built zero-carbon neighborhood, demand controlled exhaust ventilation systems (DCMEV) and mechanical ventilation systems with heat recovery (MVHR) are compared under operational conditions, with focus on the energy performance of bot
Improving the usability and performance of heat recovery ventilation systems in practice | 2018 | English | 6 pp
The use of heat recovery ventilation systems is becoming more and more common. It is clear that these systems contribute to energy efficiency and good indoor air quality. Still there is room for improvement.
Subjective Evaluation for Perceived Air Pollution Caused by Human Bioeffluents | 2018 | English | 10 pp
The concentration of carbon dioxide is used as an important index of indoor air quality representative of body odor or bioeffluents in Japan. In the construction field of Japan, there is a CO2 concentration standard of a thousand ppm or less.
