دور هندسة القيمة في تحسين كفاءة استهلاك الطاقة بالمباني القائمة

Abstract EN

The research study aims to develop existing buildings with a more sustainable vision, taking into account the application of sustainable design concept during the planning phase of development.

Thinking about design process should be as an integrated system, where architectural side and passive design strategies can be integrated through development operations.

The different climatic conditions surrounding the building, which are determined by the region in which the building is located; the different orientation of each level of the outer casing relative to the main directions, and dividing the outer casing elements into solid and open, vary the treatment alternatives of each of these elements depending on the circumstances affecting it.

Thus, the value engineering approach gets its importance of its application to sustainable existing buildings.

The project achieves the desired objectives through a methodology that helps to choose between these alternatives on a scientific that interests in studying cost, functionality and quality, which has started to be used as one of the assistance areas of the development process in order to reach a balance point between quality and costs.

The objective of this research is to apply value engineering during the stages of existing building's development and its impact on the design decisions through an analytical study of the mandatory requirements of the outer casing of existing buildings to improve energy consumption, use the value engineering approach in comparison, choose among the available alternatives during work phases of the architectural project and take the decision which achieves the highest quality at the right cost.
