Volume content
Impact and benefits of the air cleaning measures implemented in two schools | 2023 | English | 10 pp
Effects of ventilation on airborne transmission: particle measurements and performance evaluation | 2023 | English | 2 pp
This research aims to evaluate ventilation performance on airborne transmission in buildings, by analyzing the effect of different ventilation configurations and flow rates on contaminant removal effectiveness
Evaluation of Uncertainties of Using CO2 for Studying Ventilation Performance and Indoor Airborne Contaminant Transmissions | 2023 | English | 10 pp
The COVID-19 pandemic has raised concerns about indoor ventilation conditions worldwide.
An approach has previously been developed to estimate space-specific carbon dioxide (CO2) levels that can serve as metrics for the adequacy of outdoor ventilation rates.
Low energy buildings are highly insulated and airtight and therefore subject to overheating risks, where Ventilative Cooling (VC) could be a relevant solution in both existing and new buildings - being both a sustainable and energy efficient solut
To achieve future-proof buildings, it is crucial to design buildings and systems that can withstand to shocks (like heat waves and power outages) and reduce the impact of shocks on thermal comfort in a building.
Overheating in school buildings is likely to lead to a negative learning performance experience for occupants in these settings.
A Danish office building designed with a hybrid ventilation system has been compared to a full mechanical ventilation system in the same building.
Embedding robust yet accessible frameworks to evaluate ventilative cooling potential during the early/concept design stages for building practitioners can help in reducing the performance gap as well as avoiding vulnerability “lock-in” from design
The growing challenges of climate change, urbanization, and increased energy demand have underscored the critical need for sustainable and resilient cooling solutions in buildings.
Towards performance-based approaches for smart residential ventilation: a robust methodology for ranking the systems and decision-making | 2023 | English | 12 pp
Smart ventilation which provides air renewal thanks to its variable airflows adjusted on the needs can improve both indoor air quality (IAQ) and energy performance of buildings.
Metal Oxide Semiconductor sensors (MOS) for measuring Volatile Organic Compounds (VOC) - performance evaluation in residential settings | 2023 | English | 10 pp
Metal Oxide Semiconductor (MOS) sensors measuring Volatile Organic Compounds (VOC) seem to be an obvious step towards broadly available Demand Controlled Ventilation (DCV).
Impact of the building airtightness and natural driving forces on the operation of an exhaust ventilation system in social housing in Chile | 2023 | English | 9 pp
Chile has 1,626 social housing complexes with a total of 350,880 dwellings.
Measurement of ventilation effectiveness and indoor air quality in toilets at mass gathering events | 2023 | English | 10 pp
Mass gathering events were closed in 2020 to reduce the spread of SARS-CoV-2. These events included music concerts, theatre shows, and sports matches.
Indoor air quality in Austrian classrooms – Assessing different ventilation strategies with a citizen science approach | 2023 | English | 9 pp
With many existing Austrian school buildings to be renovated in the coming years, there are debates between stakeholders, about which ventilation strategy to pursue in existing schools.
Ventilation behaviour of occupants driven by outdoor temperature: 12 case studies | 2023 | English | 10 pp
This paper presents the results of an Indoor Environment Quality (IEQ) monitoring study (including relative humidity, temperature and IAQ in terms of indoor CO₂) in naturally ventilated dwellings (mainly based on vertical shafts and infiltrations)
The presentation provides a brief overview of the current situation and a roadmap for decarbonizing the building stock under the context of EU directives. It also discusses how it could be implemented into Spanish building regulations.
Comparative Analysis Between Indoor Temperatures of Dwellings at Urban Scale During a Typical and Extreme Summers in a Temperate Climate | 2023 | English | 10 pp
This study examines the impact of heatwaves on indoor operative temperatures of dwellings in Pamplona (north of Spain) and presents a comparative analysis of a typical summer and two extreme summers with heatwaves in 2003 and 2022.
How to create a performance-based regulation on ventilation – the French Experience | 2023 | English | 10 pp
In France, in Residential buildings, since 1982 the ventilation regulation imposes air flow rate to be continuously extracted from every room with humidity production. A boosted level of air flow rate shall be reachable in the kitchen.
Quantifying the Potential Health Impacts of Unvented Combustion in Homes – A Meta-Analysis | 2023 | English | 10 pp
While a growing body of scientific literature describes the population health impacts of fossil fuel production and burning via climate and air pollution pathways, less is known about the health impacts of indoor combustion.
