Abstract:
The paper focuses on studying the behavior of the sun’s movement
during a building model in Khartoum State, by studying the results of common
daylight simulation programs with data measured on-site and in the virtual
situation. Verifies the accuracy and limitations of programs when used to
calculate daylight illumination or light reflected from other buildings under
conditions varying by month or year. The aim of the study is a systematic
approach between the actual and expected results and possible predictions,
choosing the appropriate design options according to the climatic situation
of the region. The study concluded that simulating the diffused daylight in
the northern and western facades in particular is the hottest of the year, and
this lies in the fact that the treatments and materials used as sun refractors
were Tested using Climate Consultant 6.0 programmers, as well as good correlation
at low values and higher values in the average thermal comfort, in
addition to the size. Information that helps through the Climate Consultant
6.0 programs, and on the other hand, CLIMAPLUS programs, clarifies the
important factors that help reduce energy consumption and makes clear to us
the aspects What is mitigated is the use of false ceilings and double glazing
and the use of materials with poor heat transfer coefficients. We can summarize
that the role of programs is very important to save time and save energy
