MARN Despacho Superior

EDGE Advanced

MARN Despacho Superior is an office building part of the Ministry of the Environment and Natural Resources of Guatemala, located in central Guatemala City. In its role as the public authority overseeing environmental matters, the ministry has directed actions towards sustainability through the Integrated Green/Sustainable Building Program, including the application of the EDGE Certification, which has been a mechanism for learning, research and recognition of the application and achievement of objectives in the reduction of consumption, energy water and proper management of materials and waste.

The project consists of a retrofit of an existing 408 square meter office building which is part of the historic city center of Guatemala City and which has been designated as a structure of national and cultural heritage. The project will serve as a pioneer in the retrofit of existing buildings in this category.

Through the use of energy-efficient technologies such as reflective paint for external walls, an energy-efficient HVAC system, LED lighting, water-efficient plumbing features and the re-use of existing structures such as floor, walls, and roof, the project was able to significantly reduce energy and water use and particularly energy embodied in materials.

MARN Despacho Superior has received Final EDGE Advanced Certification from Green Business Certification Inc. (GBCI).
