Facing the global overheating through mitigation and adaptation technologies - the role of ventilation | 2019 | English | 1 pp
Regional climate change in cities is the most documented phenomenon of climate change . Higher urban temperatures are documented experimentally for more than 450 major cities in the world.
Traffic sources contribute a large portion of the ambient nitrogen dioxide, particulate matter and ozone concentrations, the three ambient air pollutants with the largest impact on human health in Europe (EEA, 2018).
Smartness is all around us. The HVAC industry is developing more and more products that have sensors, are intelligent, are connected to the Internet and are being controlled via apps.
Introduction: Why performance-based assessment methods? Overview of the needs and the possibilities | 2019 | English | 6 pp
In future building regulations 2020, building performance is going to be extended to global performance, including indoor air quality (IAQ).
Performance-based assessment methods for ventilation systems: Overview of on-going work in France and in Europe | 2019 | English | 3 pp
In the field of energy performance, successive regulations pushed a "performance-based" approach, based at least on an energy consumption requirement at the design stage for heating and/or cooling systems (Spekkink 2005).
As a consequence of the sustainable politics demanding regulations that allow the use of more efficient ventilation systems, the IAQ Spanish regulations were modified and enforced in 2017.
Challenges and limitations of performance based approaches: the Belgian experience | 2019 | English | 3 pp
Performance based approached for ventilation started to be used in Belgium in 2008 in the context of EP regulation.
Demand controlled ventilation: Sensitivity and robustness of the performances | 2019 | English | 2 pp
Demand controlled ventilation (DCV) seems to be the main way to comply with both energy and internal air quality (IAQ) concerns.
Applicability of a simple and new airtightness measuring method and further comparisons with blower door measurements | 2019 | English | 8 pp
The building airtightness is essential to achieve a high energy performance. In most countries however, it is not mandatory to measure the airtightness. In the Netherlands it is common practice to just take a couple samples in a housing project.
Refined assessment and comparison of airtightness measurement of indoor chambers using the blower door and Pulse methods | 2019 | English | 11 pp
Previous studies have compared the airtightness measurement of test enclosures utilising both the novel Pulse technique and the conventional blower door method.
Evaluation of indoor pressure distributions in a detached house using the Pulse airtightness measurement technique | 2019 | English | 10 pp
Building airtightness is a critical aspect for energy-efficient buildings as energy performance of a building can be reduced significantly by poor airtightness.
Insights into the impact of wind on the Pulse airtightness test in a UK dwelling | 2019 | English | 10 pp
Requirements for measuring the building airtightness have been proposed and included by many countries for national regulations or energy-efficient programs to address the negative effect of poor airtightness on building energy performance, durabi
Estimation of Air Leakage Sizes in Building Envelope using High-Frequency Acoustic Impulse Response Technique | 2019 | English | 10 pp
Heating energy in buildings represents a significant proportion of the total global energy consumption. Uncontrolled airflow through the building envelope contributes significantly to its energy losses.
Deviation of blower-door fans over years through the analysis of fan calibration certificates | 2019 | English | 14 pp
Mandatory building airtightness testing has come gradually into force in European countries, mostly because of the increasing impact of building leakage on the overall energy performance of low-energy buildings.
HVAC and VOCs: interaction between building systems and indoor VOC concentrations | 2019 | English | 2 pp
HVAC systems in newly built or extensively renovated dwellings were all developed with the aim for energy saving with equal or better comfort.
Alternative ducting options for balanced mechanical ventilation systems in multifamily housing | 2019 | English | 3 pp
Duct routing often poses a great challenge when planning the installation of a mechanical ventilation system with heat recovery.
Lessons learned from a ten-year monitoring in residential buildings equipped with humidity based demand controlled ventilation in France | 2019 | English | 3 pp
Humidity-based DCV systems have been widely used in France for 35 years and are considered as a reference system, including for low-energy residential buildings.
The present paper aims at illustrating the practical use of the Annex68 IAQ Dashboard. To this end, numerical simulations have been performed to provide useable data about the Indoor Air Quality (IAQ) of a low-energy detached house.
