Figure 6:Comparison between the five systems according to categories weight Conclusions The summarize, developing a Local Green building Code, System or Regulation is mandatory for each country to achieve the desired degree of greenness according to the local priorities, and implementation (Regulatory Framework) for sustainable practices that will serve more in building performance and sustainability and expected to perform much better when using local regulations. However, main categories for sustainable design are common between all systems; each local code or system should address these categories and indicators accordingly and in line with the local content. In addition to the local green regulations required, green regulation for existing buildings with minimum renovations and practices to be implemented is also required in order to integrate the total image towards sustainability. Furthermore, concentrating on both design and construction stages is one of the important aspects to reach the sustainability goals. Obligating some green practices toward energy and water efficiency (water irrigation system, insulation materials, rainwater collection, materials separation for recycling) as part of building permit conditions would ensure achieving some of sustainable practices and requirements. Many research and studies addressed that to enhance building thermal performance in Jordan towards energy efficiency, still the strict regulations followed by regular construction inspection required to implement the efficient practices recommended by these studies. Based on the review and analyses undertaken in this study, through comparison and evaluation of both the international rating and local systems, the following more specific conclusions can be drawn: Each one of the compared systems assigns the majority to the local priorities. Energy efficiency has the highest percentage in categories weight of the fourth systems (LEED, BREEAM, PEARL and Jordan Green Building Guide), while SABA tool gives the majority to water efficiency tacking in to consideration that Jordan is one of the world poorest countries with respect to water resources. In contrast, Jordan Green Building Guide assigns (38.73%) to energy efficiency comparing with 266 ZEMCH 2015 | International Conference | Bari - Lecce, Italy
