Environmental considerations for construction projects

Ecology Impact

Ecological footprint of a construction project includes all environmental impacts, from extraction of raw materials to disposal of waste.
It is essential to conduct an Ecological Impact Assessment (EIA) before starting a project to identify potential environmental impacts and mitigation strategies.
Construction activities should aim to preserve natural habitats wherever possible, and consider remedial actions if damage is unavoidable.

Selection and Sourcing of Materials

The selection of construction materials should consider their lifecycle environmental impact, from extraction and manufacturing to disposal at the end of their usefulness.
Materials should ideally be sourced locally to reduce the environmental impacts of transportation.
The use of recycled or reclaimed materials can greatly reduce the environmental impact of a construction project.
Materials and products used should have Environmental Product Declarations (EPDs) or equivalent, showing a complete environmental footprint, including CO2 emissions and water use.

Energy Usage

Construction projects should aim to minimise energy consumption during construction through efficient site management.
Measures should be taken to optimise fuel and electricity use, and reduce the need for artificial lighting and climate control.
The use of renewable energy sources on-site, like solar-powered lighting, can significantly reduce the carbon footprint.
Long-term energy efficiency of the building should also be considered, such as insulation standards and incorporation of renewable energy systems in the design.

Water Usage and Management

Water usage during construction should be minimised by implementing water conservation strategies like rainwater harvesting and reusing water.
Effective drainage systems are vital to prevent localised water contamination and flooding.
Construction materials that require minimal water for processing and installation are preferred.

Waste Management

Effective strategies for waste management should be planned and implemented, such as reducing packaging, reusing materials, and recycling waste.
Environmental impact of waste disposal should be minimised by following the waste hierarchy, prioritising waste prevention and reuse over recycling, energy recovery, and disposal.
Hazardous waste should be appropriately identified and disposed of safely to protect both environment and public health.
