This paper discusses the importance of understanding the ecology as part of architectural education. Rather than focusing on the heat phenomenon as frequently researched, this paper explores the opposite ideas by identifying the concept of cool pocket and designing it as a mean for heat mitigation in a tropical built environment. Recent researches show that providing a microclimate that responds human thermal comfort can contribute to the building energy performance and at the same time promote activities in outdoor space. The relation and interaction among various microclimate factors with the land, water body, arrangement of vegetations, building’s geometry and configurations, create different scenarios of the thermal condition, including possible cool pocket. Using air temperature and wind as indicators, possibilities of cool pocket will be explored and investigated through CFD Simulation. The result shows the importance of ecological understanding as part of designing cool pocket in a tropical context in a learning process and scenario-based simulation in developing design strategies.

Due to their porous nature, lightweight aggregates have been shown to exhibit thermal properties that are advantageous when used in building materials such as lightweight concrete, grout, mortar, and concrete masonry units. Limited data exist on the thermal properties of materials that incorporate lightweight aggregate where the pore system has not been altered, and very few studies have been performed to quantify the building energy performance of structures constructed using lightweight building materials in commonly utilized structural and building envelope components. In this study, several lightweight concrete and masonry building materials were tested to determine the thermal properties of the bulk materials, providing more accurate inputs to building energy simulation than have previously been used. These properties were used in EnergyPlus building energy simulation models for several types of commercial structures for which materials containing lightweight aggregates are an alternative commonly considered for economic and aesthetic reasons. In a simple model, use of sand lightweight concrete resulted in prediction of 15–17% heating energy savings and 10% cooling energy savings, while use of all lightweight concrete resulted in prediction of approximately 35–40% heating energy savings and 30% cooling energy savings. In more complex EnergyPlus reference models, results indicated superior thermal performance of lightweight aggregate building materials in 48 of 50 building energy simulations. Predicted energy savings for the five models ranged from 0.2% to 6.4%.
