| dc.description.abstract | Rapid development of urban areas catalysed the movement of people from rural
areas to urban areas. This led to the demand for more dwelling places. Urbanisation
and industrialisation caused the replacement of permeable land cover into
impermeable materials. More solar radiation is absorbed by impermeable materials
as it has thermal bulk properties and causes for the increase of urban temperature.
Change in urban microclimate causes the phenomenon to be identified as urban heat
island effect, which is identified from the temperature difference between urban and
rural areas. In Sri Lanka, a few researches have been conducted on UHI effect for
developed and existing cities. Identifying potential UHI mitigatory steps is vital
when designing urbanities. Therefore, analysing UHI effect and possible mitigatory
strategies for proposed cities through simulation studies are highly beneficial in
developing sustainable cities. The research focused on investigating the potential of
utilising simulation studies to identify UHI mitigatory steps for proposed cities in
local context. Rhino 3D simulation software was utilized for the study. The paper
presents the results of initial studies conducted. Research methods and workflow
developed through the study can be utilised to evaluate the UHI effect, mean radiant
temperature (MRT) and universal thermal climate index (UTCI) to identify outdoor
thermal comfort. This software and methodology can be used for future
developments to identify the UHI effect as a result of the completion of the project
and mitigation methods that can be used to negate the UHI effect and enhance
human comfort. | en_US |
