The Impact

With the rise in awareness of energy efficient buildings and adoption of mandatory energy conservation codes across the globe, significant change is being observed in the way the buildings are designed. With the launch of Energy Conservation Building Code (ECBC) in India, climate responsive designs and passive cooling techniques are being explored increasingly in building designs. Of all the building envelope components, roof surface has been identified as the most significant with respect to the heat gain due to the incident solar radiation on buildings, especially in tropical climatic conditions. Since ECBC specifies stringent U-Values for roof assembly, use of insulating materials is becoming popular. Along with insulation, the shading of the roof is also observed to be an important strategy for improving thermal performance of the building, especially in Warm and humid climatic conditions. This study intends to assess the impact of roof shading on building’s energy performance in comparison to that of exposed roof with insulation. A typical office building with specific geometry and schedules has been identified as base case model for this study. This building is simulated using energy modelling software ‘Design Builder’ with base case parameters as prescribed in ECBC. Further, the same building has been simulated parametrically adjusting the amount of roof insulation and roof shading simultaneously. The overall energy consumption and the envelope performance of the top floor are extracted for analysis. The results indicate that the roof shading is an effective passive cooling strategy for both naturally ventilated and air conditioned buildings in Warm and humid climates of India. It is also observed that a fully shaded roof outperforms the insulated roof as per ECBC prescription. Provision of shading over roof reduces the annual energy consumption of building in case of both insulated and uninsulated roofs. However, the impact is higher for uninsulated roofs (U-Value of 3.933 W/m2K), being 4.18% as compared to 0.59% for insulated roofs (U-Value of 0.33 W/m2K).While the general assumption is that roof insulation helps in reducing the energy consumption in tropical buildings, it is observed to be the other way when insulation is provided with roof shading. It is due to restricted heat loss during night.

Building Designs

Support for the modular system of building construction, touted in the second half of the 20th century as the best basis for academic library building design, appears to be waning. A study of “green” libraries in 2008 revealed that not only has energy conservation become important, but that spaces designed for users rather than books have become paramount. The modular system worked particularly well for housing ever-expanding book collections, but collection growth is no longer a practical goal. Users want and need a greater variety of spaces, which purpose-built rooms are better at meeting.

In Iran, urban block morphology has changed as a result of the architectural focus shifting away from traditional concerns such as climate-and-energy sensitivity onto issues such as land use, transportation and finance. Current architectural practice while has completely overlooked the architecture of the past, failed to improve the quality of life. The hot, arid climate in combination with non-responsive urban building design has resulted in high energy consumption to keep occupants comfortable. Although it is possible to overcome many of the negative effects of an inefficient design by the use of mechanical systems, this thesis through an architectural response, explores the role of climate sensitive strategies, practiced in the traditional architecture, in recognizing the importance of energy conservation. While it is only at the urban scale that energy-saving strategies could effectively tackle problems, the applicability of these principles will be studied at a neighbourhood scale.

Total Energy Consumption

Environmental concerns and growing energy costs raise the importance of sustainable development and energy conservation. The building sector accounts for a significant portion of total energy consumption. Passive cooling techniques provide a promising and cost-efficient solution to reducing the energy demand of buildings. Based on a typical residential case in Hong Kong, this study aims to analyze the integration of various passive cooling techniques on annual and hourly building energy demand with whole building simulation. The results indicate that infiltration and insulation improvement are effective in regard to energy conservation in buildings, while the effectiveness of variations in building orientation, increasing natural ventilation rate, and phase change materials (PCM) are less significant. The findings will be helpful in the passive house standard development in Hong Kong and contribute to the further optimization work to realize both energy efficiency and favorably built environments in residential buildings.
