Mosaic Green Roof

Project Objective

The project aims to create a pleasant space on the roof of the office building by implementing a green roof/mosaic roof solution in compliance with LEED Platinum standards. This intervention seeks to maximize adaptation to the evolving Mediterranean climate, reduce the ecological footprint, and improve water resource management.

The construction was carried out in phases, with completion expected in January 2025. The roof is designed to require minimal maintenance and no irrigation, following criteria of environmental and structural efficiency.

Description of proposal

Characteristics of the Green Roof

Construction System

Ultra-lightweight inverted roof with XPS and soil build-ups, where shrub vegetation is intensified to minimize structural loads.
Adaptation to different slopes and drainage points, preventing water stagnation.
Distribution of point loads over structural pillars to ensure roof stability and optimize weight.
Reinforced waterproofing with a double root-resistant layer to protect the structure.

Adaptation to the Mediterranean Climate

Design of an intensive green roof system, without the need for continuous irrigation.
Only an initial establishment irrigation is planned to ensure vegetation growth.
Invisible underground tree support systems, minimizing visual impact and improving anchorage to the substrate.

Botanical Selection and Vegetation

The selection of plant species has been key to ensuring resistance and adaptability to the extreme Mediterranean climate. A high percentage of native species have been chosen, requiring minimal maintenance and resistant to prolonged drought conditions.

Conclusions

The green roof project of the new office building not only meets sustainability and energy efficiency requirements but also offers a high-value aesthetic and ecological landscape solution. Its implementation demonstrates the feasibility of green roofs adapted to Mediterranean climates, serving as a reference in bioclimatic architecture and sustainable urban planning.

With completion expected by January 2025, this intervention will represent a tangible example of integrating nature into built environments, promoting coexistence between modern infrastructure and the native landscape.
