Volume content
Analyzing natural ventilation and cooling potential in a communal space building in Belgium under future climate conditions | 2023 | English | 8 pp
Thermography-based assessment of mean radiant temperature and occupancy in healthcare facilities | 2023 | English | 10 pp
Due to its high demands regarding indoor environmental conditions, healthcare facilities are associated with high energy consumption.
Urban context and climate change impact on the thermal performance and ventilation of residential buildings: a case-study in Athens | 2023 | English | 10 pp
Urban settings and climate change both impact energy use, thermal comfort and ventilation of buildings.
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).
Which design parameters impact the resilience to overheating in a typical apartment building? | 2023 | English | 10 pp
Airtight, highly insulated, and passively cooled buildings in the EU are designed under typical outdoor and indoor thermal conditions.
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.
Statistical analysis of the correlations between buildings air permeability indicators | 2023 | English | 3 pp
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).
On the integration of envelope pressure inhomogeneity and autocorrelation in fan pressurization uncertainty analysis | 2023 | English | 12 pp
Improving the knowledge on uncertainty for fan pressurization measurement is of first importance.
Gas phase air cleaning effects on ventilation energy use and indicators for energy performance | 2023 | English | 8 pp
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).
Exploring the Energy-Saving Benefits of Gas-Phase Air Cleaning in Nordic Buildings | 2023 | English | 2 pp
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.
Air Cleaner as an Alternative to Increased Ventilation Rates in Buildings: A Simulation Study for an Office | 2023 | English | 2 pp
Indoor air pollution is a significant concern due to its adverse effects on human health and productivity.
International Energy Agency (IEA) Annex 78 was launched in 2018.
Towards an alternative cooling: Optimisation of the successive use of the cooling systems from passive to active - Development of design and control strategies of the hybrid cooling | 2023 | English | 10 pp
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.
An IAQ and thermal comfort coach prototype to improve comfort and energy consumption thanks to adequate management of natural ventilation: development and first feedback results | 2023 | English | 2 pp
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.
An innovative approach to better understand hot discomfort, based on the measurement of global human responses, including physiological and sensory indicators - application to end users of mixed mode cooled buildings under tropical climate conditions | 2023 | English | 10 pp
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.
Windows and ceiling fan occupant behaviour model coupling methodology with building energy models, a tropical case study | 2023 | English | 9 pp
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.
In the United States, the realm of building enclosure design and commissioning is separate and distinct from the realm of mechanical design and commissioning.
Airtightness predictive model from measured data of residential buildings in Spain | 2023 | English | 10 pp
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.
Correlation analysis between ACH50 and Air permeability considering the floor area of a residential buildings | 2023 | English | 7 pp
Airtightness is presented through various expression according to the standards and measurement methods of each country.
Due to the minimal energy requirement, the Passivhaus standard has been widely recognised and adopted to deliver low carbon buildings.
