Once you have identified and evaluated the factors that matter to you, you can compare and select the best sustainability certification for your commercial property. To do this, research and review the certification schemes, shortlist and rank them according to suitability and feasibility, consult and confirm with stakeholders, and apply and achieve the certification. Gather information on requirements, processes, fees, benefits, and case studies from online resources, industry publications, professional associations, and peer networks. Narrow down your choices to a few that meet your criteria and preferences using a scoring system or decision-making tool. Seek input and approval from management, staff, tenants, investors, advisors through surveys, interviews, workshops or presentations. Consult with the certification bodies or experts to clarify any doubts or questions. Follow the guidelines of the certification body when applying for the certification and use their tools and resources to prepare documentation. You may also hire a consultant or contractor to assist with implementation and verification of the certification.
