<html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-9"> </head> <body bgcolor="#FFFFFF" text="#000000"> Dear esp-r Users, We would like to simulate a 43 storey high office building (located in a Mediterrenean climate) with double facade for energy calculation purposes. The double facade is a single cavity on all four sides of the building and from first floor to the top floor. The depth of the cavity ranges between 3 - 5 meters. The design intent is to ventilate it via thermal buoyancy and also operable windows on the exterior skin (automatic control). No natural ventilation of the office interiors or night time cooling is foreseen at the moment. We would like to analyse the best ways of design and operation and see how much we can decrease the HVAC cooling / heating running costs. We intend to use esp-r and DOE/eQuest for this. I would appreciate any suggestions on how to approach this task. Thank you, Ömer Moltay, LEED AP BD+C, ASHRAE BEMP, CPMP, BREEAM Assessor Mimta EkoYapi Hekimsuyu Cad. 559. Sk.
