Energy Conservation for an Office Building in a Hot Climate

Kuwait is located in Middle east region. The weather is very hot.During summer the Ambient temp becomes 52 ?? C db, and relative humidityvaries between 40 % to 60%. Kuwait area is also very dusty due to sand dust .HVAC design is a very challenging today. ASHRAE 90.1 – is a standard guidelines related to energy saving. Year after year the power requirementbecoming less to save energy as well carbon di oxide generation to control the environment. Ministry of electricity and water ( MEW) have formulatedsome guidelines in this aspect. Façade glazing, Thermal Energy storage ( TES) , Energy Recovery Unit ( ERU) etc will play related to Energysavings. Manufacturer also trying to improve Energy Efficiency Ratio ( EER) of products like chillers, fans etc and they are concentrating ondevelopment of product by research and development. Noise reductions also Energy Conservation for an Office Building in A Hot Climate , KuwaitIn this paper, An office building have been considered. Office area is air conditioned by Underfloor system. To reduce HVAC plant capacity ,Thermal storage – Chilled water by Indirect interface system have been considered.The influence of following parameters like UFAD ( Underfloor air distribution system}, Facade glazing factor like “U” (Overall Heat Transferco efficient}, SHGF ( solar Heat gain factor} , Thermal Energy Storage ( TES) for Partial loading , ERU (Energy Recovery Unit) etc. will bediscussed and the contribution as percentage of energy saving will be presented.An approx 10-15 % energy have been saved .Keywords, UFAD,SHGF,MEW,ERU, TES.
