Other studies focused on the "Reuse" aspect. They deal with it as a sustainable way to protect heritage. This paper assumes that the first step for dealing with the architecture heritage is to rebuild the intellectual image for it, which have a great influence in understanding its characteristics and knowing its plastic properties.  In this digital age, specialists were able to rebuild the intellectual image for the architectural heritage in more details. Using complicated and interactive digital models for heritage buildings as a touristic and educational applications, gave a life to new terms, such as (Virtual Museums), (Virtual labs), (Virtual Caves) and (Virtual Heritage). The last became very important in dealing with the architectural heritage. Usually, The main process in virtual reality construction focused on building digital models for the architectural heritage itself, which considered uncompleted view. The complete one considered the architectural heritage as a life construction full of value and culture, which deserves concern as well as the architectural plastic values.  The paper presents a wider view, trying to use virtual reality techniques over place and time dimensions. It covers another dimension, the inherent values and the generic culture in people life style, which can help us to know more and understand the past clearly. These complete digital models could have a great role in revival the architecture heritage innovations. }, keywords = {}, url = {https://bfemu.journals.ekb.eg/article_122530.html}, eprint = {https://bfemu.journals.ekb.eg/article_122530_111de826f0369cd582fa845760382d3d.pdf} } @article { author = {Abou-Liela, Mohamed M.}, title = {Material Resources Management for Educational Building Using GIS (Case Study: Faculty of Engineering-Mansoura University).}, journal = {MEJ- Mansoura Engineering Journal}, volume = {36}, number = {2}, pages = {12-22}, year = {2020}, publisher = {Mansoura University, Faculty of Engineering}, issn = {1110-0923}, eissn = {2735-4202}, doi = {10.21608/bfemu.2020.126289}, abstract = {This study aims to ascertain the concept of Material Resources Management for Educational Building Using Geographic information system (GIS), as an important means of information management.

The Internet provides a convenient point-to-point communication network that replaces dedicated telephone lines. Inexpensive computers equipped with suitable communication and control software manage the distributed resources.
