Ventilation and Thermal Performance Examination of Slot Line Diffuser for Perimeter Usage by CFD Simulation | 2023 | English | 10 pp
Building ventilation demand increased during the “new normal” following the Covid-19 pandemic. Rather than completely renovating existing HVAC equipment, it is more practical and cost-effective to maximize their existing ventilation performance.
Construction of operational control rules for an earth-to-air heat exchanger through transfer reinforcement learning | 2023 | English | 10 pp
In recent years, earth-to-air heat exchanger (EAHE) systems, which is a method of pre-cooling and pre-heating outdoor air with earth-to-air heat, have been attracting attention as one of the technologies to achieve ZEB.
On the assessment of the pressure coefficient on the mixed ventilation modeling | 2023 | English | 10 pp
The accurate estimation of the local wind pressure coefficient is crucial in the numerical modeling of natural or mixed ventilation in buildings subjected to wind.
Long-term energy performance of dew-point indirect evaporative cooler under the climate change world scenario | 2023 | English | 9 pp
The progressive increase in the global average outdoor air temperature has caused an increase in the cooling demand in buildings in recent years.
The Effects of Lowering Temperature Setpoints on Perceived Thermal Comfort – An experimental study in office buildings | 2023 | English | 7 pp
This study investigates the impact of lowering temperature setpoints on occupants' thermal comfort in office buildings, prompted by government initiatives in Europe, including the Netherlands, to reduce energy consumption.
Sea Water Air Conditioning (SWAC): A Resilient and Sustainable Cooling Solution for hot and humid climates - Energy Performance and Numerical Modeling | 2023 | English | 9 pp
Sea Water Air Conditioning (SWAC) is a highly efficient alternative to conventional air conditioning that uses deep seawater as a cooling source (Free Cooling).
Performance comparison of different ventilation strategies in elderly care homes in Belgium | 2023 | English | 11 pp
Elderly people residing in nursing homes spend a vast majority of their times indoors and often in common recreation areas, to allow for socialization and interaction. Elderly people are a vulnerable age group.
Method for Evaluating an Air-Conditioning System with Natural Ventilation by Coupled Analysis of a Building Energy Simulation Tool and Computational Fluid Dynamics | 2023 | English | 8 pp
In office buildings, an air-conditioning system with natural ventilation can reduce cooling loads and create a comfortable indoor environment.
A study on desiccant system regenerated by waste heat from home-use solid oxide fuel cell cogeneration system | 2023 | English | 10 pp
Since the spread of covid-19 in 2019, it is necessary to realize an indoor environment that takes measures against viral infections such as covid-19 and influenza virus.
Wind Tunnel Experiment of Wind-Induced Single-sided Ventilation under Generic Sheltered Urban Area | 2023 | English | 10 pp
The utilization of natural ventilation helps to reduce building energy consumption and improve indoor air quality. In the urban area, the performance of the natural ventilation is very sensitive to surrounding building density.
Development of air supplied ceiling radiant air conditioning system using the Coanda effect | 2023 | English | 7 pp
Air-supplied ceiling radiant air conditioning is expected to become more popular in Japan in the future because there is no leakage from pipes and no condensation on the surfaces of radiant panels.
Reflections on alternative modelling approaches regarding occupants' window operation behaviour | 2023 | English | 8 pp
Computational predictions of buildings' indoor-environmental conditions and energy performance would presumably benefit from the inclusion of models that could reliably capture occupants' window operation behaviour.
Energy Implications of Increased Ventilation in Commercial Buildings to Mitigate Airborne Pathogen Transmission | 2023 | English | 9 pp
One proposed mitigation to reduce transmission of the SARS-CoV-2 virus and other airborne pathogens is to increase ventilation in buildings.
Monitoring and regulating the air quality inside critical infrastructure is essential for protecting occupants from external and internal airborne threats, such as pollutants, toxic chemicals, and pathogens.
Monitoring VOCs’ concentrations in a circular biobased residential building using low-cost sensors | 2023 | English | 9 pp
Most current building materials are industrially processed, resulting in increased carbon emissions. Global annual carbon emissions due to construction materials reached its peak in 2013, 9.5 gigatons of CO2 were produced.
Car traffic or emissions from heating sources: What is responsible for IAQ? | 2023 | English | 10 pp
The quality of indoor air in buildings depends on many factors. Some of these factors have internal sources, and some have external sources.
Hygienic Air Handling Unit Certification Program: the new necessity for a guaranteed indoor air quality | 2023 | English | 18 pp
Nowadays, people spend most of their time indoors. Homes, offices, leisure and workplaces must meet people’s needs and provide safe, healthy and productive environments. The supply of fresh air plays an important role in achieving these goals.
Experimental Investigation of Indoor Air Quality in an Open Office Environment | 2023 | English | 9 pp
Open offices, where more than one person works, have been used frequently in recent years. However, there are many studies on the efficiency of the indoor air quality of the employees in these offices.
Proposal of an effort-benefit diagram to compare unit and room air-change rates applied to a literature review | 2023 | English | 9 pp
The main task of every ventilation system is to dilute and extract pollutants from indoor air, most importantly in occupied space. This is usually achieved by exchanging polluted indoor air with less polluted outdoor air.
