Energy Management & Energy Efficiency

With energy management and energy efficiency measures, buildings can run smoothly, keep costs down, and keep comfort as a top priority. Measures include efficient lighting, controls, proper ventilation, plug load management, and zone heating & cooling.

Sustainable Agriculture

Water and resource conservation are central to sustainable agriculture. USEE’s services utilize techniques for improved irrigation and water usage, as well as soil revitalization through nutrient infusion.

Advanced Policy & Regulation

Incorporating lessons learned from external markets, through our long-term consultation with the Gambian government, USEE advises on policy and regulation to encourage buildings, communities and cities to be sustainable and resilient to climate change.

Stormwater Management

Stormwater is a resource and a pollutant, depending on how it’s managed and/or collected. USEE’s services include implementing stormwater harvesting before it is released into the environment, rainwater harvesting to reduce runoff volume, prevent erosion, and flooding, as well as recharge groundwater.

Waste Management

From building operators to city planning, USEE evaluates holistic solutions to waste including recycling, organics recycling or composting, and other common waste streams to minimize material headed to landfill or incineration.

Wastewater Management

Wastewater management systems that are planned and designed to cater to the phase-wise development of the city ensure that the requirements are met at each phase. USEE works with both centralized or decentralized systems, depending on the resources available and operational needs.
