Green Infrastructure (Green Roofs/Walls)

Creating green infrastructures involves the growing of plants on, around, up, or in buildings. With this, green spaces are expanded on pavements, car parks, driveways, roads, and buildings, promoting ecosystem services. [1]
Climate Adaptation Effectiveness

Structural vegetation can provide insulation and can stop flash floods through surface drainage. [1], [3]

Evaluations

Economic / Financial Effectiveness
Low

Green wall system installation can cost around Php 6,000 to 7,000 per square meter. Green roof price ranges from Php 3,800 to 4,000 per square meter. [2]

Technical Feasibility
Low

If properly executed, green roofs can store at least 55 liters of water per square meter, serve as effective storm drain management systems, and leakproofing is very lightweight, and requires low maintenance [2]. Green wall landscaping, however, is still in its infancy in the Philippines with only a few companies offering the service. [2]

Social Acceptability
Low

Cost-inhibitive factors and risks prevent widespread installation of green roofs and green walls [3] but booming high-rise and condominium markets are opportunities for expansion.

Environmental Impact
High (+)

Expanding green spaces in urban areas improves biodiversity. The presence of vegetation also removes air pollutants. [1]

Mitigation co-benefit

Green roofs and green walls reduce energy use and decrease the carbon footprint of buildings. [1]
