Long-term durability of humidity-based demandcontrolled ventilation: results of a ten years monitoring in residential buildings | 2018 | English | 12 pp
In-situ performance of mechanical humidity-based mechanical exhaust ventilation (RH-MEV) is characterized in this study.
Feedback on installation, maintenance, and aging of mechanical humidity-controlled ventilation exhaust units | 2018 | English | 12 pp
With 35 years of existence and more than 10 million equipped dwellings, mechanical humidity-based demand-controlled ventilation (RH-DCV) can provide a comprehensive feedback on installation, aging, and maintenance of its components.
From Technical Appraisal of Demand-Controlled Ventilation Systems to Indoor Air Quality Assessment Using the Thermo-Hygro-Aeraulic code MATHIS | 2018 | English | 5 pp
The communication presents the Technical Appraisal Procedure followed in France for Demand-Controlled ventilation systems through the illustration of the use of a thermo-hygro-aeraulic nodal model called MATHIS developed by CSTB.
Demand controlled ventilation systems are representing a large majority of installations in France. They are commonly used for more than 35 years.
Recent studies have shown that ventilative cooling reduces overheating, improves summer comfort and decreases cooling loads. Therefore, it is considered as one of the most efficient way to improve summer comfort.
Ventilative cooling in a school building: evaluation of the measured performances | 2018 | English | 11 pp
The test lecture rooms of KU Leuven Ghent Technology Campus are one the demonstration cases of IEA EBC Annex 62: Ventilative Cooling.
Validation of Dynamic Model BSim to Predict the Performance of Ventilative Cooling in a Single Sided Ventilated Room | 2018 | English | 10 pp
Ventilative cooling (VC) is an application (distribution in time and space) of air flow rates to reduce cooling loads in spaces using outside air driven by natural, mechanical or hybrid ventilation strategies.
The influence of thermal mass on the predicted climate cooling potential in low energy buildings | 2018 | English | 10 pp
Even in Northern European climates, overheating in many Nearly Zero Energy Buildings is a barrier to year round occupant satisfaction with the indoor thermal environment.
Status and recommendations for better implementation of ventilative cooling into Danish standards, building legislation and energy compliance tool | 2018 | English | 10 pp
Ventilative cooling (VC) is an application (distribution in time and space) of air flow rates to reduce cooling loads in spaces using outside air driven by natural, mechanical or hybrid ventilation strategies.
Key findings of four years of research on Ventilative Cooling and how it is done | 2018 | English | 11 pp
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.
The new air tightness class in ductwork - Aeroseal technology to seal leakages in new/retrofit ductwork and duct components - the foundation for highest energy efficiency in ventilation systems | 2018 | English | 2 pp
Aeroseal technology utilizes air laden with fine aerosol particles (2-20 μm) to pressurize a duct system, resulting in deposition of those particles at the leaks within that duct system.
The implementation of the Energy Performance of Buildings Directive 2010/31/EU recast puts increasing pressure to achieve better building and ductwork airtightness.
Statistical analysis of about 1,300 ductwork airtightness measurements in new French buildings: impacts of the type of ducts and ventilation systems | 2018 | English | 8 pp
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.
Ductwork Airtightness in the UK: Requirements and Assessment of Installed Performance | 2018 | English | 4 pp
A ductwork system that has limited air leakage, within defined limits, will ensure that the design characteristics of the VAC system are sustained. It will also ensure that energy and operational costs are maintained at optimal levels.
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.
A review of smart ventilation energy and IAQ performance in residential buildings | 2018 | English | 9 pp
In order to better address energy and indoor air quality issues, ventilation needs to become smarter.
In 2017, the Air Infiltration and Ventilation Centre (AIVC) identified smart ventilation for buildings as a new and important topic to be addressed.
Amid the contaminant issues, air pollution has awakened more interest due to its potential health risk and its direct effect on human productivity.
Development of a zonal model to assess indoor climate and damage risks to art works in church buildings | 2018 | English | 8 pp
Most of the degradation of works of art in historic buildings is caused by unfavourable indoor climate conditions.
