“…The challenge is to improve the IEQ with optimizing energy consumption. Wong and Mui (2009) investigated the non-linear increasing trend of annual energy consumption required for improving thermal comfort in air-conditioned offices. Catalina and Iordach (2012) found that an increase in window to floor ratio and window type resulted in a 31% decrease in the annual energy consumption.…”

Indoor environmental quality (IEQ) is becoming a key aspect considering the building envelope and occupants' health. A lot of energy is consumed to achieve the satisfactory IEQ in the building. The main challenge for the building designer is to enhance the IEQ with the minimum energy consumption. The present paper investigates the contributing parameters and different assessment models for IEQ. The presented study will be helpful to analyse multi-functional parametric comfort and in turn will help to improve the occupant's health. IntroductionThe major purpose of buildings is to provide a healthy and comfortable environment for occupants. In most parts of the world, people spend more than 90% of the day in indoors. The indoor environment results from the interaction of the site, the climate, the building system, and the building occupants. The number of related complaints has increased in recent years with increased building tightness, growing use of materials that consume natural resources, and increase in energy use to achieve indoor comfort. The comfort of an indoor environment is very much affected by weather elements. Comfort is a way of measuring occupant's satisfaction which in turn can directly affect health and productivity.Globally, with the rapid growth in urbanization and increase in the number of dwelling units, achieving the comfort of an indoor environment by natural means is a major challenge to the designers. Today's building industry is minimizing a different kind of footprint: the energy, carbon, and environmental footprint of buildings. The aim in the building's design or renovation phase should include improvement of the building's energy efficiency and reduction in environmental impact of the building. Optimal energy management in the building sector is the key factor in energy conservation. Due to the importance of good quality of the indoor environment and the problems caused by high energy consumption, various government agencies have enacted a series of policies and regulations aimed at increasing the energy efficiency of dwellings and ensuring a good indoor environment. The building designers have a challenge to achieve the indoor comfort with the least energy requirement. In order to investigate the aspect of indoor environmental quality (IEQ), data collection methods for

“…To maintain an acceptable condition for almost 90% of the building occupants, the CO 2 concentration should be maintained at around 1000 ppm . Fine particulate (including PM10 and PM2.5) and VOCs can also be used as substitutional indicators of the required ventilation for an acceptable IAQ (Rea 2000;Chung and Burnett 1996;Mui and Wong 2006;Ayr et al 2003;Wong and Mui 2009). The main building energy that was used in this study for analysis with the indoor air pollutant factors was thermal energy consumption.…”

The buildings' indoor condition called "indoor environmental quality (IEQ)" has become a major goal, all IEQ elements must be maintained within a certain range for the comfort and health of the occupants. To achieve this goal, the previous studies focused on building occupants' responses based on their activities and the changes in IEQ. Few studies, however, have comprehensively analyzed the above and reflected it in building design and operation. The study of this concept can be expressed as "human-building interaction management." This approach is a paradigm for the healthy, sustainable, and simultaneous management of people, IEQ, and buildings. This study conducted an in-depth literature review on the abovementioned studies. In addition, it ultimately proposed an intelligent planning unit (IPU), a new approach that can be used as a tool to apply the above human-building interaction concept to the practical design concept focusing on the planning phase. The IPU theory is designed to meet the customer expectations for the various objectives of a complex built environment. Eventually, it is expected that the proposed IPU concept will promote the spread of good health and environment-friendly buildings.

“…Most importantly, the "net rent" basis of common leasing arrangements in Australia, the UK, and the USA, see the tenant paying for energy costs, providing no incentive for landlords to make capital investments to improve building services beyond what is delivered. These aspects of lease management conspire against to create arrangements where the provision of IEQ remains the purview of building owners, and largely out of the control of the tenants who actually occupy the space (Wong & Mui, 2009). Despite these constraints, the Australian and New Zealand property companies outperformed their overseas counterparts in key environmental, social and governance indicators.…”

Addressing two common challenges for building performance-reducing the carbon footprint attached to the provision of comfortable indoor environments, and improving the health and wellbeing of occupants-requires a more comprehensive understanding of how the indoor environments of buildings are operated. This paper introduces SAMBA, a state-of-the-art monitoring station for continuous, real-time measurements of indoor environmental quality (IEQ) parameters from occupants' work desks. It combines a hardware solution that integrates a low-cost suite of sensors with a software platform designed to automatically analyse and visualize data for quick interpretation of IEQ performance by non-scientist. In addition to feeding a massive IEQ database for research, the resulting data may be used to better inform the metrological requirements for popular international IEQ rating schemes. This new era of indoor environmental monitoring based upon systems such as SAMBA affords a fundamentally new approach to built environmental field research that holds significant promise to improve building performance and indoor environmental quality and occupant satisfaction, health, wellbeing and performance.
