    Abstract
    Rapid development of urban areas catalyzed the movement of people from rural areas to urban areas. This led for the demand of more dwelling places. Urbanization and industrialization cause for the replacement of permeable land cover into impermeable materials. More solar radiation has been absorbed by impermeable materials as it has thermal bulk properties and cause for the increase of urban temperature. Change of urban microclimate caused the phenomenon identified as urban heat island effect which is identified from the temperature difference between urban and rural area. In Sri Lanka few researches have conducted on UHI effect for developed and existing cities. Identifying potential UHI mitigatory steps is vital when designing urbanities. Therefore, analyzing 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 utilizing 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 utilized to evaluate the UHI effect, mean radiant temperature (MRT) and universal thermal climate index (UTCI) to identify the 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 project and mitigation methods that can be used to negate the UHI effect and enhance the human comfort.
