    The hot and humid climate requires the use of air conditioning machines almost all year round. An extensive amount of low temperature condensate water can be harvested through the commercial and residential high rise building’s large cooling capacity plant. The research reported that this alternative source could be estimated the amount of chilled water condensate that is generated during the cooling and dehumidification process in the air conditioning machines. The paper demonstrated that considerable amount of condensate water 368.0 l.Hr-1 mean 1.5 liters. Hr-1/ kW latent cooling capacity can be collected through fresh air handling unit (FAHU) being used in multi floors building of Ground +15 floors building and utilized for the pre cooling of associated recirculated air conditioning machines. The cooling capacity saving 15 percentage (%) and power input by 18 percentage (%) can be achieved by pre cooling the condenser’s out door entering air. Total saving of AED 3240($910)/month can be attained through the FAHU of this multi floors building.
