“…PCS have actively been researched upon in the recent whilethere have been three major review studies on the topic in the past 5 years. Godithi et al reviewed multiple Personal Environmental Control (PEC) Systems used for Thermal, Visual, and Acoustic Comfort, along with the controllable plug load-based systems [7]. Warthmann et al studied the past researches on Personal Thermal Comfort Systems, categorized them on the basis of devices and detailed upon the human-centred closed loop control (HCCLC) platform for PCS control [18].…”

“…Additionally, various logical control approaches are discussed and explored in [166] and [167] to control the energy consumption and comfort of residents due to ACs. Various standards are explained in [168] and [169] to observe the relationship between dry bulb temperature and indoor humidity in order to maintain indoor comfort levels. For AC efficiency enhancement and energy management, dry bulb temperature and indoor humidity are measured and kept under control at the same time to change room air conditions for AC.…”

Nowadays, the most notable uncertainty for an electricity utility lies in the electrical demand of end-users. Demand response (DR) has acquired considerable attention due to uncertain generation outputs from intermittent renewable energy sources and advancements of smart grid technologies. The percentage of the air-conditioner (AC) load over the total load demand in a building is usually very high. Therefore, controlling the power demand of ACs is one of significant measures for implementing DR. In this paper, the increasing development of ACs, and their impacts on power demand are firstly introduced, with an overview of possible DR programs. Then, a comprehensive review and discussion on control techniques and DR programs for ACs to manage electricity utilization in residential and commercial energy sectors are carried out. Next, comparative analysis among various programs and projects utilized in different countries for optimizing electricity consumption by ACs is presented. Finally, the conclusions along with future recommendations and challenges for optimal employment of ACs are presented in the perspective of power systems.

“…Recent studies on visual comfort have predominantly focused on the non-visual effects of daylight and optimal use of daylight that not only improve the building energy performance but also have positive effects on occupant's health and well-being. 32 Some of the simulation-based studies have quantified daylight glare based on the existing indices. The experimental study should combine the subjective assessment with objective factors for an overall evaluation of daylight glare.…”

This paper demonstrates the implementation methodology for India’s first IEQ standard (ISHRAE Standard-10001:2016) in actual buildings. The IEQ standard encompasses the definitions of IEQ elements (i.e. thermal comfort, indoor air quality, visual comfort, and acoustic comfort), threshold values of IEQ parameters determining these elements, specifications of measuring instruments, and methodology to undertake IEQ assessments in buildings. The pilot study identified the preliminary findings to understand and evaluate the practical implementation of the IEQ standard through field measurements. The quantitative measurements of IEQ elements were carried out in two academic buildings in the Jaipur climate (warm and humid as well as hot and dry and cold). The occupant’s subjective evaluation was made through a questionnaire survey administrated concurrently with physical measurements of IEQ parameters. This study provides the clarity of method for taking IEQ measurements and comments on the availability of instruments and their specifications as recommended by the standard. Practical application: The present study is the practical implementation of the IEQ standard in buildings. This standard provides the threshold limits of IEQ parameters by classifying them into three classes covering international and local benchmarking. The standard also specifies the research methodology including field measurement protocol and specification of monitoring devices for IEQ assessment. This standard is useful for evolving IEQ rating of buildings in India where the majority of the building stocks are yet to be built.
