The purpose of this paper is to reduce energy consumption in an operating United Arab Emirates (UAE) based governmental organization buildings utilizing DMAIC (Define, Measure, Analyze, Improve, Control) cycle.
Applying DMAIC cycle on a case study of a government organization in the UAE was used to validate the process.
The outputs showed that using cool paint will save around 238,000 kWh/year with a payback period of 0.09 year. Furthermore, by combining two technology, cool paint and a smart occupancy sensor, the amount of total energy saved will be 339,100 kWh/ year this is equivalent to saving 240,314 kg of carbon dioxide (CO2). The cost benefit is saving 111,120 AED/year this equal to 15% of the yearly bill.
The study suffers from the reliance of specific and limited literature which has a different building typology most of which, never implemented DMAIC. Moreover, the data used in the research only considered total energy consumption therefore allowing for some assumption bias regarding specific loads.
The research investigates government building in one emirate in the UAE to save energy by applying Six Sigma DMAIC methodology thus providing a unique context of application to the existing body of literature. Furthermore, the research contributes to Economic consideration since reducing energy consumption for a building is a financial investment in a capital asset meanwhile proving useful for future implementation.
The research further proved the significant benefits of applying DMAIC/Lean Six Sigma methodology in reducing energy consumption. Furthermore, utilizing UAE based governmental building as technical case study which is rare given the rules surrounding UAE public sector.
