ISIAQ's New Journal: Indoor Environments

Elsevier and the International Society of Indoor Air Quality and Climate (ISIAQ) are proud to introduce Indoor Environments, a new international, multi-disciplinary research journal dedicated to advancing the field of indoor environmental sciences. This journal will serve as a vital platform for researchers, scholars, and professionals interested in all aspects of indoor environments, including health, comfort, and climate change adaptation and mitigation.


The Effects of Environment and Living Behavior on Learning Efficiency in Educational Settings

In recent years, emphasis has been placed on improving workplace productivity. Workplace productivity is defined as “results of workplace activities for investment”. The investments mean indoor environment equipment costs, maintenance costs, and equipment costs. On the other hand, the workplace activities required mean understanding knowledge and information and using them correctly, and realizing new ideas and them. Also, it is expected that the Learning efficiency would be improved by improving the thermal environment of the education site.

The Influence of Balconies on the Indoor Environmental Conditions of Dwellings

The balcony is defined as an in-between architectural element that has the ability to intermediate the indoor and the outdoor environmental conditions. Through history, distinct balcony solutions have been used to improve the indoor environment according to their suitability to different contexts and climate conditions. The main aim of this study is to evaluate the impacts of different balconies on indoor environmental quality (IEQ) of dwellings in the mild climatic conditions of Portugal.

Numerical Evaluations of a Multiple 3D Particle Tracking Velocimetry System for Indoor Air Flow Study

High-quality data obtained from three-dimensional Particle Tracking Velocimetry (3D PTV) is pivotal for indoor environment engineering when designing ventilation strategies or monitoring airborne pollutants dispersion in inhabited spaces. A new method is proposed to link multiple 3D PTV systems, positioned side by side so that the entire measuring volume can be covered. An algorithm is developed to establish a link between the particles' trajectories calculated by each 3D PTV system.

Applying NABERS IE to a University Building in the UK

It is no longer sustainable to look at the performance of buildings in isolation of people that use them. This paper examines what is involved in assessing how a building performs for people. The Rose Bowl at Leeds Beckett University is an iconic building designed to BREEAM Excellent. The experience of staff and pupils in classrooms, offices and lecture theatres was proving to be less than excellent.

Evaluation of Indoor Environment Subjective Perception in Large Office Building

Office buildings are significant contributors to energy consumption and greenhouse emissions, and it is obvious that office building occupants and their behavior play an essential role in building energy performance. However, how buildings, respectively, their indoor environment, influence building occupant´s behavior, wellbeing, and productivity is not so clear and easy to predict. The main problem is that this correlation is very subjective and influenced by many factors.

Defining Health: Update From ASHRAE SGPC10 Committee, Interactions Affecting The Achievement Of Acceptable Indoor Environments

Healthy Buildings has become the marketing focus, if not the goal, for an increasing number of projects and organizations in the past five years. The current COVID-19 pandemic has placed a new and compelling spotlight directly onto buildings of all types, whether offices, homes, retail, restaurants, hotels, or schools. The issues are no longer limited to the functional parameters of the building design, construction, maintenance, and use.

Impacts of the Indoor Environment in Our Homes and Schools on Child Health

Today, more than 26 million European children are living in unhealthy homes putting them at higher risk of experiencing health problems. Good air quality, sufficient access to daylight and adequate ventilation are important for creating a healthy indoor environment in any home, with the effects reaching far beyond childhood. Our research is based on analysis of the Eurostat microdata from the EU-wide survey “Income and Living Conditions in Europe” (EU-SILC).

Do Spatially Distributed Sensor Measurements Provide Better Representation of Indoor Environment than Single Sensor Measurements? A Mechanically Ventilated Office Space Case Study

Most existing office buildings are equipped with indoor environmental quality (IEQ) sensors that are connected to the Building Management System (BMS) and provide feedback to the heating, ventilation and air-conditioning (HVAC). Unfortunately, they are often installed in locations selected based on practical reasons rather than for reliable representation of IEQ at actual workplaces. This leads to a difference in the IEQ sensed by the BMS and the occupants, resulting in increased complaints and decreased occupant satisfaction.

Effect on Thermal Comfort and Energy Consumption of Different Installation Height and Supply Air Angle of Room Air Conditioner by Simulation

Improving actual operation performance of room air conditioners (RAC) shows great importance in the indoor environment and building energy conversation. The installation height and supply air angle of the indoor unit of RAC directly affect thermal comfort and energy performance in heating conditions. In this paper, a combined simulation of building, indoor air distribution, and performance of RAC is proposed to investigate the influence of installation height and supply air angle. The combined simulation model was validated by experiment results.
