Abstract
When thinking about traditional Iranian architecture, one imagines extensive ornamental patterns that adorn almost every surface of mosques and other prominent buildings. Yet, many theories of architecture since the beginning of twentieth century have considered ornamentation a superficial and superfluous layer. But, are these ornamental surfaces superficial and can they be removed so easily? This paper uses a qualitative research methodology based on theoretical cross examination and critical analysis to highlight the significance of surface and appearances in architecture and argue that formulating a strategy to adorn architecture is in fact the generating gene of every architectural movement, from Modernism to Postmodernism and even to Parametricism of recent times. By setting up a philosophical and a theoretical discourse about the notion of surface and the various metaphors used in architectural theory, this paper concludes that from the woven walls of first architectural spaces to the clothed walls of modern times, surfaces have played a sacred role in architecture, and rather than being superficial barriers that mask reality, they are indeed the very materials with which architects demarcate space and create new aesthetics.

Abstract
Urban planning and morphology are one of the most important factors affecting land surface temperature (LST) and microclimate chrematistics. The production of anthropogenic heat, mainly for cooling systems and lighting, has resulted in significant impacts on the quality of the thermal environment. These impacts include poor air quality, increased temperatures, higher energy consumption, and the development of urban heat islands (UHIs). With the growing urban population and increased building height, especially in metropolitan areas, there have been significant changes in the urban geometry, rate of pollution, amount of heat released, and meteorological parameters. All these factors contribute to the heat island phenomenon and significantly alter the microclimate in urban areas. The goal of this article is measuring the effects of height changes in buildings around Tehran metropolitan squares in a detailed plan on microclimatic changes. As part of a research study, the Hafthoz Square in Tehran was chosen as a case study. The researchers used a combination of simulation techniques (Envi-met) and GIS to detect the spatial variation of Land Surface Temperature (LST) and determine its quantitative relationship with building height and density. This was achieved through simulation modeling for the Narmak neighborhood of Tehran. As Conclusion, the results indicate that comparison on the simulation between the existing conditions and proposed scenario area showed that in the proposed scenario, wind speed and relative humidity decrease and ground surface temperature (UHI) and PPD and PMV indices increase. Therefore, if the detailed plan of Tehran metropolis is realized and implemented in many squares, it will be accompanied by changes in micro-climatic parameters in order to reduce the thermal comfort of citizens.
