ABSTRACT

Today, as in every subject, architectural designs gain new qualities under new approaches and disciplinary trends and are shaped according to new perspectives. Therefore, there is a need to introduce new sanctions in line with the advancing trends and developments in the design and application of architectural projects. In architectural project design, parcel-based construction rules such as "Building Height", "GCR", "FAR" (See Appendix) and "Building Approach Distance" may not be sufficient to produce solutions suitable for today's urbanization conditions, architectural trends and approaches. In this regard, it has been thought that new solutions should be sought, emphasizing the need to support the construction rules with some additional sanctions. In this article, a new construction rule is explained. This rule supports the consciousness of the infiltration of the green element into urban building parcels and the buildings on the parcels as in parallel with today's ecological settlements that are at peace with nature, green architecture and increasingly developing new urbanism trends. For this purpose, first of all, the importance of reflecting the green element on the building level is explained in terms of the phenomenon of urbanization in accordance with new trends with a nature-friendly and sustainable approach. Then, the Green Area Coefficient (GAC) at the building level, which is proposed and formulated in this sense, is defined. In the rest of the article, GAC and the shares of this coefficient formulated on the building and its plot are stated. Then, the calculated values of the construction rules in question with certain assumptions are presented in tables, and a flow chart is proposed for calculating the amount of planted area at the building level depending on all these coefficients. As a result, schematic explanations are made for the newly proposed GAC construction rule and the application is clarified.
