(IEEE, 2017-10) Basnayake, B. A. D. J. C. K; Amarasinghe, Y. W. R; Attalage, R. A; Jayasekara, A. G. B. P; Devinda, M. G. K
Under this research, the multi-sensory feedback system has been developed utilizing commercially available MEMS based and miniaturized sensors for building automation systems. This system consist of non-contact infrared thermal array sensor based occupancy identification / localization system and self-floor locations categorization system with an environmental monitoring system. Further, it has smart realtime energy monitoring system which capable to identify the load devices and their status while operation. The entire system is capable of obtaining quantitative values of this sensory information and applied for the development of more convenient and energy efficient automation in building premises. The implemented system was tested and validated using fuzzy logic based building automation controller via the wireless network.

Occupancy identification based energy efficient Illuminance controller with improved visual comfort in buildings
(IEEE, 2017-05-29) Basnayake, B. A. D. J. C. K; Amarasinghe, Y. W. R; Attalage, R. A; Jayasekara, A. G. B. P
Under this research Smart energy efficient and visual comfort lighting system has been developed based on the presence of occupancy and occupancy localization information. The developed system consist of non-contact occupancy identification system, wireless sensor network, and wireless light intensity control device. The controller is constructed on a fuzzy logic based closed loop controller developed on a single board computer powered by 900MHz quad-core ARM Cortex-A7 CPU. Lighting is an important factor in maintaining the visual comfort in a living premise. According to literature, the lighting consumes about 40% of total electricity consumption in a building. Since lighting energy requirement contains a larger share of energy demand any saving from that demand will result in a reduction in areas of energy wastage, negative impact to the environment and the cost to the consumers and so on. The results of the experiment indicate that the improvement of visual comfort and enhanced energy performance by avoiding of unwanted visual comfort level in a living premise.

Smart solar tracking and on-site photovoltic efficiency measurement system
(IEEE, 2016-04-05) Basnayake, B. A. D. J. C. K; Jayathilaka, W. A. D. M; Amarasinghe, Y. W. R; Attalage, R. A; Jayasekara, A. G. B. P
On-site photovoltaic efficiency data is a valuable asset during a process of predicting photovoltaic potential. Not just the solar power output, but also the ambient conditions and panel temperature should be measured for a better and convinced results. Due to the unavailability of on-site data, erroneous conclusions have been made after various prediction methods. Smart solar tracking and on-site photovoltaic measurement system is proposed as a novel tool to be used in solar potential predictions which can measure and log on-site solar data. This device is capable of measuring and logging available solar power together with ambient measurements such as light intensity level, ambient temperature and humidity level and panel temperature. Measured data will then be stored in an internal memory card and will be available at any moment. Integrated wireless communication module will enable remote log-in and control of the device. Computer based Graphical User Interface (GUI) software application enables the remote access to the gathered data and optimization of its operation.
