Abstract:
Air conditioning was considered a luxury in earlier days and now it becomes a general
requirement due to urbanization, new constructions, modern architecture, regulations and
standards etc. In early days there were no limitations on space and also there were lot of
greenery which supports concepts such as natural ventilation.
Therefore importance of establishing proper procedure for AC system development is great
and this study aims at developing a systematic procedure for selection of efficient AC
system/equipment for different type of commercial buildings.
Literature review discuss broadly on technologies, standards and regulations, energy
efficiency, Calculation techniques and tools, Building envelope improvements which is the
flat form for development of a methodology to achieve research objective. Methodology
developed consist of three phases namely Design, Testing and Commissioning, Operation
and Maintenance. In Sri Lanka focus is mainly given for design phase and neglect T & C, O
& M phases which is so critical for success of the project.
Once methodology established guidelines have been developed for easy reference so that
even layman can understand approach required for development of efficient AC system for
his new building. Real time case study presented for better understanding of proposed
methodology and further improvement on the study can be done by monitoring applications.
Finally recommendations were given based on research study outcome for real time
applications.
