The Impact and implication of the Energy Efficient Building Code in Sri Lankan context

Abstract

Being a scared resource energy conservation is becoming an important issue today It believes that the new energy conservation regulations considerably contribute to solve the problem generating because of the scarcity of energy .As a new experience the energy related regulations creates so many debuts within professional groups such as Architects and engineers who directly involving^ the construction industry and many of them have less knowledge in this area The study pays special attention for the section of building envelope which come under Energy Efficient Building Code introduced by the Ceylon Electricity Board in year 2000 and the recommendations have taken under that. The study examines the behavioural pattern of the Overall Thermal transfer value (OTTV) with the contemporary design parameters and energy consumption in Sri Lankan context. Doing so , the first chapter deals with the literature review , discussing the nature of the energy , importance of conserving energy , conservation approaches concentrating the energy efficient building code in Sri Lanka. The second chapter deals with the impact of the external and internal heat gains. The way of heat gain and heat transfer and OTTV as an index for a heat transfer in to the building envelope in theoretical basis and further the properties of the building material which contributes to determines the nature of OTTV. Third chapter examines the nature of the OTTV under five cases for 17 design parameters and analysis have done under five base cases and the findings used to identify the practicability of the OTTV and it have been given suggestions with a set of guidelines which help the architects and designers to designs building envelope under the EEBC recommendations. The presence of energy efficient building cord in Sri Lanka
