AWDABPT for Buildings and AWDABPT-UG are computer programs for the estimation of the average room air, surface and core temperatures of the rooms of a building, shelter or underground enclosure for equipment and/or people.


They were developed as design aids to assess new concepts and, in particular, to reveal trends due to the variation of selected parameters relating to the thermal performance of such accommodation.


The relevance of the predictions provided by the program can be no better than the extent to which the user's input data correctly models the subject building.


Whenever possible, testing of the program's results against measured building temperatures should be done. Some validation has been done in the past by others on concrete culvert buildings, insulated steel stud and clad air conditioned buildings with phase change material standby cooling, a naturally cooled, thermally transparent shelter and outdoor telecommunications equipment cabinets with and without the assistance of an air-to-air heat exchanger.


Both programs were written by Allan Wishart BE, MIEAust, CPEng, MAIRAH. He has used this software over many years for the thermal design of accommodation of heat dissipating equipment whether it be a standard building, a naturally cooled thermally transparent shelter, a kerb-side cabinet or an underground enclosure. Applications are located in Australia, Pacific Island countries and India for example.   

The current versions have evolved from a software model originally developed on an HP86B desktop computer around 1984.



Examples of some of the (known) projects for which this software was used for the thermal design:


  Telecommunication repeater station buildings for the Kandla - Bhatinda pipeline, India, Indian Oil Corporation Limited.

  Houses - for cooling and heating loads and room temperatures when outside conditions exceed 10 or 15 worst days of the year.

     

  Small multi-storey buildings.

  

  Various telco buildings and outside cabinets.

        
        An ice bank is used for standby cooling.
     
     
      Outside telco cabinets being prepared for thermal performance testing. The second one includes an air to air heat exchanger.
   Outside telco cabinets under test. A friendly comparison of AWDABPT software with that from a large international company was undertaken by a qualified third party (CSIRO). AWDABPT software did not require any modification.
         Induction cooling coils served by peak-lopping water storage system cooled to overnight low outside temperature.
   This building protects the entrance to an underground telecommunications equipment enclosure.
