Several international systems exist for measuring sustainability compliance such as BREEAM in the UK, LEED in the US and CASBEE in Japan. A recent Egyptian system is termed the Green Pyramid Rating system (GPRS), and is intended to operate as a rating and certification scheme to define and encourage ecological building design and development in Egypt. Both international and local systems are uncertain in terms of their suitability to local technologies and conditions and in terms of their economics. This paper aims to discuss sustainability system elements of existing buildings in rural areas in Egypt in terms of their suitability to local conditions and economics. Ecological design principles were extracted from international systems and model eco-houses. Challenges facing ecohouses in Egypt were reviewed. The ecological design principles were applied to a case study in Wardan, Egypt, where local available technologies were used to apply the principles of indoor environmental quality, energy efficiency, water management, ecomaterials. Ecological systems are proposed for natural ventilation, photovoltaic panels, and thermal insulation and their economic viability is compared to typical air conditioning systems. The conclusion of the comparison is that the proposed ecological renovations of the case study are competitive in terms of construction costs and more economical than typical systems considering life cycle costing. It is thus recommended that government agencies and industry institutions take on awareness campaigns and research institutes direct research towards appropriate ecological technologies for new and existing buildings, whether rural or urban.

Heritage Tourism is one of the world's largest industries and biggest income generators. But the demands of tourism can have severe negative impacts on local communities and the environment if not properly developed and managed. The Development Process is important to maintain heritage sites. Also, it is a demand to inscribe heritage sites in UNESCO World Heritage List. The purpose of this paper is to improve the development process of heritage sites. The method used to address this research is a deductive method by first stating the Design Key Consideration of the development process and then concluding an evaluation checklist. Using the Evaluation Checklist, helps improving the development process of the heritage sites. The result of this paper is an evaluation checklist for the Design Key Considerations, it is used in improving the Development Process of Heritage Sites. KEYWORDS:  Heritage Tourism-Heritage Sites-Development of Heritage Sites-Design Key Considerations-Evaluation Checklist 1. INTRODUCTION: Heritage sites "Are natural or man-made sites around the world that have been internationally recognized for their outstanding value as natural and cultural treasures." Heritage Tourism can be defined as "Travel to experience the places and activities that represent the stories and people of the past and present, It includes cultural, historic sites, museums, and natural resources." Heritage is a non-renewable resource that current generations are responsible of its preservation and sustainable use. (1)
