Adoption of green building practices in EDGE is influenced by factors that incentivize or mandate resource efficiency. The EDGE User Guide discusses drivers for green building adoption: "Factors that lead to higher adoption of green building practices include green building regulations, which mandate compliance with efficiency standards; public awareness and capacity building, which educate stakeholders on the benefits of green design; and clear visibility of estimated savings and costs, which provide financial justification for green measures" (EDGE User Guide, Section 1.1: Introduction to EDGE). Option A (green building regulations) directly encourages adoption by enforcing standards: "Regulations requiring energy or water efficiency standards push developers to adopt green practices to meet legal requirements" (EDGE Certification Protocol, Section 1.2: Scope of EDGE Standard). Option C (public awareness and capacity building) increases adoption by educating stakeholders: "Awareness campaigns and training programs increase demand for greenbuildings by informing developers, owners, and tenants of their benefits" (EDGE User Guide, Section 1.1: Introduction to EDGE). Option D (clear visibility of estimated savings and costs) incentivizes adoption by demonstrating financial benefits: "EDGE’s display of savings and payback periods motivates adoption by showing the return on investment for green measures" (EDGE User Guide, Section 2.4: Interpreting EDGE Results). However, Option B (lower electricity supply costs) may not lead to higher adoption, as it reduces the financial incentive to save energy: "Lower electricity supply costs decrease the cost savings from energy efficiency measures, potentially discouraging investment in green practices, as the payback period for measures like insulation or efficient lighting becomes longer" (EDGE Methodology Report Version 2.0, Section 4.4: Cost Savings Calculations). The EDGE User Guide further elaborates: "High utility costs often drive green building adoption by making energy and water savings more financially attractive, whereas lower costs can reduce the urgency to implement efficiency measures" (EDGE User Guide, Section 1.2: Scope of EDGE Certification). In this context, lower electricity supply costs (Option B) may not encourage green building practices, as the economic motivation for energy savings diminishes.
