Abstract
Egypt has great heritage assets including the heritage buildings that have high values, most of them, suffering from deterioration, negligence, non-investment, and non-periodic maintenance. Most of the conservation projects of heritage buildings in Egypt don’t include any procedures that aim to make the building more compatible with the environment during the restoration works or be more efficient during the operation period, that’s lead to a failure or a lack in achieving the goals of the comprehensive conservation strategy and sustainability. Since the seventieth of the 20th century, many countries all over the world have faced several energy crises that had a great role to concentrate the studies on how they can reduce the energy consumption. That’s lead to emergence of the practices of ”green buildings” that became more widespread during the last two decades.Green building design and construction practices that meet specified standards will help resolve much of the negative impacts that buildings have on their occupants and on the environment. The green principles are applied on the new buildings and the existing building after making some modifications on the building to be green. Most of the current green certified heritage buildings all over the world have been assessed under the rating systems of existing buildings umbrella, some of them have set minimum requirements for heritage building, and the others don’t have any requirements related to heritage buildings, that could lead to loss the values of those building in the process of transforming them as green Buildings. The research aims to produce a Green Heritage building Rating System tool which can assess the green heritage buildings in Egypt. This tool aims to merge the principles of the green building practices in the conservation strategies of the heritage buildings, that’s mean achieving a comprehensive sustainability for heritage building to meet the current and future needs through conserving the building, maintaining it, and applying the green practices without harming or losing the heritage value of the building.
