indoor environment

This session will begin with providing an overview of presence Personal Environmental Control Systems (PECS) related mention in various countries national codes and standards formulated by industry organizations. It will then articulate possible entry points for PECS in policy document such as building codes, health and safety code and voluntary building performance rating programs. Towards end, it will identify market barriers, market challenges and market opportunities that may aid widespread deployment of PECS.  

Personal Environmental Control Systems (PECS) enable to individually control the environment in the immediate surroundings of an occupant regarding the thermal, air quality, acoustic, and/or luminous domain without directly influencing the entire space and other occupants’ environment. Although many studies on the influence on the respective comfort and acceptance in relation to the different domains already exist and estimates of energy savings have already been made, PECS have not yet established themselves on the market across the board.

This summary highlights the benefits of PECS for occupants’ health, comfort, and cognitive performance. A comprehensive literature review was conducted using databases such as Scopus, Web of Science, and Google Scholar, focusing on terms related to personalised conditioning, air quality, lighting, and acoustics. Relevant studies were identified and reviewed. 

The project aims to investigate the degree of influence that outdoor conditions may have on the indoor environment in Norwegian schools. It also aims to ascertain whether it is possible to use outdoor parameters such as particulate matter, relative humidity, and air temperature, along with indoor parameters including CO2, relative humidity, and air temperature, to predict indoor particulate matter values.

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 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.

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.

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.

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.
