Leed, Edge & Trees Certification - Auditing and Consulting Services

LEED, EDGE, & TREES Certification

DMG recognizes the importance and prestige of having projects certified by an accredited third party organization. We have accredited professionals that can certify your building with the LEED and TREES systems. DMG also has EDGE Auditors that can review your project to guide it to EDGE certification.


LEED (Leadership in Energy and Environmental Design) is the recognized world leader in green building certification systems. No system has more registered projects worldwide than LEED. LEED certified buildings have proven to less impact on the environment and provide operational costs savings through less use of energy and water. LEED buildings also provide a better internal air environment and thus can lead to better employee attendance by preventing sick building syndrome and provide a healthier environment for families. LEED achieves this by focusing on several categories for sustainable buildings:

  • Integrative Process
  • Sustainable Sites
  • Location and Transportation
  • Water Efficiency
  • Energy and Atmosphere
  • Indoor Environmental Quality
  • Innovation in Design
  • Regional Priority

The LEED rating now offers a wide range of construction project types and specialties:

  • Building Design and Construction: New Construction and Renovation
  • Existing Building and Maintenance
  • Neighborhood Development
  • Homes
  • Interior Design and Construction


EGDE is a green building system for residential and commercial buildings. EDGE was created by the International Finance Corporation (IFC) to foster more green building projects in the developing world by providing a simple rating system. EDGE’s free software enables you to determine the most cost-saving options for your building’s resource-efficient design. If you earn a minimum of 20% less energy, water and embodied energy in materials, and your project has met the EDGE standard.

The EDGE software shows quickly how committing to a few practical energy and water-saving options improves building performance without incurring much if any additional costs. The savings are quickly calculated and displayed to reveal the most economically viable path to a sustainable building design. Designers input their building location and design data online, choosing from a list of common sustainable features, to yield results of savings in energy, water, and material embodied energy.

Once the software results are approved, a project can apply for certification. EDGE’s certification involves documenting and verifying the design data on site. After the Auditor visit the documentation is presented to and EDGE certified reviewing organization for final certification.


DMG is proud to be able to offer it’s service in either the EDGE Auditor or EDGE Expert role. An EDGE Auditor Guides projects to provide the correct documentation for EDGE certification and conducts an on site audit to verify the selected measures have been implemented. EDGE Experts help developers, owners, and larger project teams understand the EDGE standard, software and certification system. The EDGE Expert advises on green building design and assists with preparation of an application for EDGE certification.





TREES(Thai’s Rating of Energy and Environmental Sustainability) is a newer system based on the USGBC’s LEED system specifically modified for Thailand. As with LEED TREES buildings have positive environmental impacts and bring cost savings to building owners. The TREES system is point based with projects being awarded points based on the categories and the sustainable measures that have been chosen.
The TREES system currently only has a New Construction category but is expanding to include other project types in the near future.
There are several credits categories as with LEED to help focus the building design on sustainability. These categories include:

  • Building Management
  • Site and Landscape
  • Water Conservation
  • Energy and Atmosphere
  • Materials and Resources
  • Indoor Environmental Quality
  • Environmental Protection
