**6.4 Deployment of passive and regenerative strategies**

Passive design strategies such as building orientation, cross-ventilation, vegetative cover, shading devices, and roof overhangs can be better deployed in the buildings. The atrium can be made to play a bigger environmental role. The design objective was aimed at maximizing the use of the site due to the development pressure on land. Green spaces were few and far between, while the buildings are closely spaced together to increase density. Lagos has a small build-able land area relative to the population and housing needs. As a result, densification is a deliberate development policy of the government. Such dense developments would have benefited from the installation of green roofs and other similar green infrastructure installations. However, no green roofs or green facades are incorporated. Hence, the ecosystem regeneration strategies were not substantially deployed. The roof adopted a lean-to

design, which helped to reduce the roof footprint, thereby conserving usage of roofing materials.
