Abstract
The research analyzed the behavior of internal heat gains within
skyscrapers as a major contributor to its overall heat gain budget,
sometimes representing the majority of these gains in an internal load
dominated building prototype.
This analysis included sources of internal heat gains, their rates related to
space function, and methods of controlling them through accurate
selection of different systems’ fragments.
For a conventional building prototype, the above methodology represents
an optimum way for internal heat gain control, however, for a skyscraper,
the extreme change of the external factors relative to altitude; mainly
ambient temperature, natural daylight contribution for dense urban
environments in addition to core configuration, puts a further dimension
for the possibility of manipulating internal heat gains contribution.
The vertical positioning of space program fragments represents the main
subject of study, where the research proved numerically that different
alternatives of vertical function mapping results different needs of
cooling and heating with respect to internal heat gains.
The research ended up with:
o Introducing a decision making tool; a specially designed computer
program supporting decision making at the schematic design phases.
The user has the ability to choose function vertical mapping within a
skyscraper having certain characteristics for its mass and external
envelope, resulting instant numerical results equivalent to these
choices.
o Monitoring favorable vertical function distribution with respect to
thermal performance - using the research tool - for a hypothetical
skyscraper with fixed mass and envelope parameters located in two
hypothetical sites: a dense urban context, and an open surrounding
context respectively. The results showed completely different
recommendation in both cases; which means the essential role of
numerical analysis for each case.
