Methodology

Review the following documents in order to gain a better understanding of the EDGE Methodology, including the cost model, embodied energy in materials, and the original EDGE Methodology Report, which is the starting point for understanding the basics of EDGE.

EDGE Methodology Report

The EDGE Methodology Report shows how a base case is established, how demand is calculated and how local climate conditions influence results. The report is intended for those who are inquisitive about underlying assumptions, equations and data sets.

India Construction Materials Database

Commissioned by the EU as part of its Eco-cities program, IFC’s “India Construction Materials Database of Embodied Energy and Global Warming Potential” is a collection of environmental data for 100 building products typically used in India, whether manufactured locally or imported. The data will be incorporated into a future version of the EDGE App.

EDGE Embodied Energy in Materials Methodology

This report outlines the methodology followed by EDGE to calculate the embodied energy in materials, which are the impacts associated with construction products due to their extraction, refining, processing, transportation and fabrication. The document has been specifically prepared for EDGE and is based on the cradle-to-gate method of life-cycle assessment of materials.

EDGE Cost Model

Supplementing the EDGE Methodology Report, the EDGE Cost Model outlines the general overall methodology followed by EDGE to create the cost database used in incremental cost calculations. The document discusses some features that will only be available in Version 3.0.0 of EDGE. Incremental cost calculations are intended to provide a sense of comparative costs rather than definitive cost estimates. The calculations integrate the impact of all options. For example, an upgrade to lighting or windows might be offset by savings from a smaller HVAC system, which can at times even produce a negative (-) incremental cost.

Protocols

This collection serves as a repository of materials on the protocols for EDGE certification.

Portfolio Certification in EDGE

EDGE certification of portfolios rather than individual building projects offers clients a more streamlined and economical choice. In portfolio, each subproject receives separate EDGE certificate as normal EDGE certification.

EDGE User Guide for All Building Types Version 3.0

This EDGE User Guide for All Building Types (Version 3.0) contains the complete list of efficiency measures available in EDGE. The consolidated guide contains a section on the EDGE certification process and policy updates in the last appendix.

EDGE User Guide for All Building Types Version 2.1

This EDGE User Guide for All Building Types (Version 2.1, Release B) contains the complete list of efficiency measures available in EDGE. The consolidated guide contains a section on the EDGE certification process and policy updates in the last appendix.

Information on embodied energy in materials can now be found separately in the Materials Reference Guide.

EDGE Materials Reference Guide Version 2.1

The EDGE Materials Reference Guide (Version 2.1, Release A) contains the complete list of materials measures found in EDGE and their respective embodied energy. The document is a companion to the EDGE User Guide for All Building Types Version 2.1.

Projects and Subprojects User Guide

The new Project and Subproject structure on the EDGE App allows users to link related project files and avoid repetitious processes.

Research Reports

Check here often for new white papers that will be added over time. They are included to help gain a greater understanding of how we can collectively make a difference through green technologies and design.

Market Intelligence – Country Reports

The Green Building Market country notes summarizes key market indicators based on IFC’s research on policy environment, building construction, and Green Building certification and finance.

The notes include the most recent Green Building developments in each country, coinciding with IFC’s with the launch of the UK-IFC Market Accelerator for Green Construction (MAGC) program.

This Green Building Market Snapshot is a summary of key market indicators based on IFC’s research on policy environment, building construction, and Green Building certification and finance. The year of the snapshot coincides with the launch of the UK-IFC Market Accelerator for Green Construction (MAGC) program in the country. Additionally, most recent Green Building developments in the market are included where available. IFC welcomes readers’ comments.

Green Building Return on Investment – Region Reports

IFC partnered with Georgetown University to conduct research using the EDGE App to analyze the most cost-effective green interventions to achieve the EDGE standard.

The analysis includes incremental costs needed to reach the EDGE standard, projected utility savings, and the payback period, which has been repeated across countries and sub-sectors. Each desktop case study includes an already certified EDGE project.

Green Building Return on Investment – Typology Reports

IFC partnered with Georgetown University to conduct research using the EDGE App to analyze the most cost-effective green interventions to achieve the EDGE standard.

The analysis includes incremental costs needed to reach the EDGE standard, projected utility savings, and the payback period, which has been repeated across countries and sub-sectors. Each desktop case study includes an already certified EDGE project.

Refrigerant Selection to Reduce Climate Impact

IFC’s EDGE Team has issued this document on coolants as guidance on how to choose a “green” refrigerant in accordance with the Montreal Protocol. Refrigerants have significant environmental impact and care must be taken in their selection and management. Note that refrigerant selection is currently beyond the scope of the EDGE certification system, and this document is only provided as guidance.

Discovery Workshop Presentations

The EDGE Discovery Workshop presentations and scripts are available in both English and Spanish for downloading to share at conferences or with clients. You can customize the slides according to a country or region of your choice. To help you customize your presentation, we’ve created case studies by region and typology that you can use.
