    Application of building management system for sustainable built environment
    Kumara, WHCD; Waidyasekara, KGAS; Weerasinghe, RPNP
    Managing a built environment environment professionals. Building Management System (BMS) is dedicated recently, considering its potential capabilities towards a sustainable in a sustainable way is the biggest challenge for the built one of the solutions that have been building. BMS is a computer based system that used to monitor, coordinate, organize, and optimize building subsystems such as HVAC, lighting, security, fire/life safety, elevators, and others. The system provides various supports for the operation and maintenance functions of Lpplication of BMS building. However, the towards a sustainable built environment is still challenged in Sri Lankan context. Therefore, this paper aims to find the preliminary investigation on application of BMS towards comprehensive literature survey sustainable built environment in Sri Lanka. A was conducted to draw the linkages between sustainable dimensions and BMS functions. An opinion survey directed to attain the aim of the study. Six industrial professionals who have experience in the process of selection, operation, and maintenance of BMS were interviewed with a semi structured interview guideline. The study identified five sequence steps of BMS implementation process namely: identifying user requirement, identifying BMS features, designing, installation and commission, and operation and maintenance. Cost, lack of confidence in result, lack of knowledge and skilled person among building professionals to execute the system in sustainable was are some prevailing issues manner.

    Building management system for sustainable built environment in Sri Lanka
    (Emerald Group Publishing Limited, 2016) Kumara, WHCD; Waidyasekara, A; Weerasinghe, RPNP
    Purpose The purpose of this paper is to investigate the contribution of building management system (BMS) towards a sustainable built environment. Design/methodology/approach The paper is based on the findings of a comprehensive literature survey, preliminary survey and a structured questionnaire survey. Quantitative data were analysed using a relative importance index. Content analysis was used for the qualitative data analysis. Findings The results show that identifying user requirements, identifying BMS features, designing BMS, installation and commissioning, and operation and maintenance are the key steps in the BMS implementation process. High cost, lack of knowledge on BMS, unavailability of service and maintenance, and inadequate performance of BMS vendors were highlighted as barriers when adopting a BMS. Energy efficiency, reduction of operation and maintenance cost, occupant satisfaction, productivity, fault diagnosis, thermal comfort, indoor air quality, emergency response and level of controllability of building systems are some of the significant BMS functions that accomplish economic, environment and social sustainability pillars. Practical implications This study increases the awareness on functionality of a BMS and its potential contribution towards a sustainable built environment. Originality/value The study develops strong ties between BMS contribution and sustainability where built environment professionals could use the developed decision support model towards a sustainable built environment through the application of BMS.

    Contribution of building management system towards sustainable built environment
    (Ceylon Institute of Builders, 2013-06) Kumara, WHCD; Waidyasekara, KGAS; Sandanayake, YG; Fernando, NG
    The biggest challenge faced by the community is controlling and monitoring the performance of built environment facilities in a sustainable way. From this dimension, effective use of Building Management System (BMS) in the built environment is representing a significant strategy in relation to economic, environment and social perspectives. Higher energy efficiency, lower operating and maintenance costs, better indoor air quality, greater occupant comfort and productivity are the major achievements of a successful BMS. Therefore, at present it is so evident that, many organizations are enhtuastic to allocatea substantial investment, inorder to, install, commissioning, operation and maintenance of BMS. However, to obtain the optimum use of BMS is still challenging among the building users. Thus, the requirement of developing a framework for functionality of BMS is essential in order to gain maximum benefits through operating building automation and control systems. The aim of the paper is to investigate the contribution of BMS in achieving a sustainable built environment. The findings are achieved through conducting literature and documentary review available in the built environment andanalyzing green building rating systems to find out the input of BMS towards sustainable built envionemnt. Therfore, comparative study conducted between LEED, BREEAM and GreenSLrating systems.Based on the findings, theoretical framework was developed to facilitate contribution of BMS in sustainable development. Moreover, the paper is engaged in analysisngthe credit contribution of BMS in order to gain the green rating certification.
