Abstract
In this paper, we analyze the recently introduced Energy Efficient Building Code (EEBC) for Commercial Buildings in Sri Lanka for its applicability to Sri Lankan office buildings. The focus is on the building envelope and air conditioning requirements of the EEBC and their effect on energy saving. In order to this, we develop a typical multi-story office building designed as per the EEBC and simulate its energy and thermal comfort performances using a parametric energy simulation software. The results reveal that the application EEBC to Sri Lankan commercial buildings will actually increase energy consumption over the present scenario. Based on our analysis we recommend a set of improvements to the EEBC in terms of building envelope and set-point temperature requirements.
Highlights
Sri Lankan architects pay little attention to the energy based) and electricity
Ceylon Electricity Board (CEB) estimates that in the Sri Lankan commercial building sector, 50-60% of the total demand is consumed The Efficient Building Code for Commercial Buildings (EEBC) deals with five major aspects of buildingby air-conditioning while 20-30% is used by the lighting level energy consumption: system
In this paper we evaluate the cooling load and thermal comfort performance of a typical" office building located in the city of Colombo and designed according to the "Ventilation & Air Conditioning" and the "Building Envelope" requirements of the EEBC
Summary
Sri Lankan architects pay little attention to the energy based) and electricity. sustained economic efficiency aspects of commercial buildings in the growth and a proliferation of rural electrification programs present context. CEB estimates that in the Sri Lankan commercial building sector, 50-60% of the total demand is consumed The EEBC deals with five major aspects of buildingby air-conditioning while 20-30% is used by the lighting level energy consumption: system. The importance of the commercial building sector in building-level energy consumption and its potential for rapid growth led the CEB to lobby for the introduction of a design code that stipulates minimum efficiency standards. Such a code - the EEBC - was developed by a World-Bank funded project in 1999/2000 and was introduced in late 2000 for a trial period of three years. OTTV is first calculated for each individual facade and for the building as a whole, taking the weighted average of the individual facade OTTVs
