Due to climate change, Western Europe is experiencing a surge in cooling demand, leading to higher summer temperatures accompanied by longer and stronger heat waves, thereby intensifying the toll on our buildings.
Shiva Khosravi, Joost Declercq, Delphine Ramon
Due to its high demands regarding indoor environmental conditions, healthcare facilities are associated with high energy consumption.
Paul Seiwert, Quan Jin, Kai Rewitz, Ulrike Rahe, Dirk Müller
Urban settings and climate change both impact energy use, thermal comfort and ventilation of buildings.
Maria Kolokotroni, May Zune, Thet Paing Tun, Ilia Christantoni, Dimitra Tsakanika
The future needs of indoor spaces in our buildings are likely to be cooling focused. With the widespread use of air-conditioning (AC) on the horizon there is now a need to ensure our systems perform as renewables (under the relevant definitions).
Adam O’ Donovan, Theofanis Psomas, Paul D. O’ Sullivan
Airtight, highly insulated, and passively cooled buildings in the EU are designed under typical outdoor and indoor thermal conditions.
Abantika Sengupta, Jef Kerckaert, Marijke Steeman, Hilde Breesch
This article provides a summary of a comprehensive examination of the current ISO 9972 standard, focusing on the enhancements needed to improve its reliability and validity for airtightness tests in buildings.
Benedikt Kölsch, Valérie Leprince, Adeline Mélois
The content presented comes from the paper under review “Quantitative correlation between buildings air permeability indicators: statistical analyses of about 500,000 measurements” (Moujalled, 2023a).
Bassam Moujalled, Benedikt Kölsch, Adeline Mélois, Valérie Leprince
Improving the knowledge on uncertainty for fan pressurization measurement is of first importance.
Martin Prignon
Gas-phase air cleaners can be used to either reduce occupant dissatisfaction for the same outdoor air flow rate or to reduce the outdoor air flow rate for the same resulting occupant satisfaction based on its clean air delivery rate (CADR).
Dragos-Ioan Bogatu, Ongun B. Kazanci, Bjarne W. Olesen
This manuscript discusses the energy-saving benefits of gas-phase air cleaning in Nordic buildings. Ventilation systems are crucial in creating a healthy and comfortable indoor environment.
Sasan Sadrizadeh
Indoor air pollution is a significant concern due to its adverse effects on human health and productivity.
Alireza Afshari, Alessandro Maccarini, Göran Hultmark
International Energy Agency (IEA) Annex 78 was launched in 2018.
Bjarne W. Olesen, Pawel Wargocki
Due to global warming, severe problems of buildings overheating during summer in temperate and hot climates arise. Thus, there is an increasing use of air conditioning.
Arnaud Jay, Aurélie Foucquier, Maxime Boulinguez, Gwénaëlle Haese, Simon Thebault, Virginie Chantepie, Jean Castaing Lasvignottes, Maäréva Payet, Simon Rouchier, Jean-Marie Caous, Pierre Constant-Beraud
Over time with thermal and energy regulations, buildings are increasingly insulated and airtight to control better the heat exchanges between the indoor and outdoor environments.
Arnaud Jay, Pierre Bernaud, Franck Alessi
Comfort modelling is a critical scientific barrier to reaching better thermal satisfaction in buildings. It allows designers to combine different cooling systems better to target comfortable low-energy buildings in hot and tropical climates.
Gwénaëlle Haese, Maxime Boulinguez, Pierre Bernaud, Anthony Couzinet
In this work, we propose a method to couple the behaviour models developed with Python in a previous paper with the dynamic thermal simulation software EnergyPlus, an advanced code used in research and design.
Maäréva Payet, Maxime Boulinguez, Mathieu David, Philippe Lauret, François Garde
In the United States, the realm of building enclosure design and commissioning is separate and distinct from the realm of mechanical design and commissioning.
David de Sola, Nathaniel Fanning
The need for airtightness control is a reality given its impact on buildings’ energy use and IAQ. For the past few years, this fact has resulted in energy performance regulations being established in many countries in Europe and North America.
Irene Poza-Casado, Pilar Rodríguez-del-Tío, Miguel Fernández-Temprano, Miguel Ángel Padilla-Marcos, Alberto Meiss
Airtightness is presented through various expression according to the standards and measurement methods of each country.
Su-Ji Choi, Jae-Hun Jo
Due to the minimal energy requirement, the Passivhaus standard has been widely recognised and adopted to deliver low carbon buildings.
Xiaofeng Zheng, Luke Smith, Christopher Wood
