At Aiguasol, we are advancing the energy transition in the Caribbean through a new initiative in Guyana, supported by the World Bank and implemented in partnership with the OECS Commission and the Guyana Energy Agency.

Together with Azimut 360 and Renew Caribe, we have evaluated the decarbonization potential of 13 public buildings across the country — including primary and secondary schools, health centers, hospitals, medical storage facilities (drug bonds), and service centers of the Guyana Revenue Authority. Each building has undergone detailed energy investment audits and monitoring, allowing us to propose tailored solutions that boost energy efficiency, reduce carbon emissions, and create positive social and environmental outcomes.

In one of the case studies, the West Ruimveldt Primary School (Georgetown), our initial diagnosis revealed opportunities such as: 

• Enhanced passive strategies to reduce solar heat gain and cooling demand. 
• Lighting upgrades, by replacing old fluorescent tubes with LEDs, and optimizing existing LED systems for efficiency.
• Ceiling fans in non-conditioned areas to improve thermal comfort. 
• Photovoltaic (PV) panels installed on the roof to act as sun barriers while generating renewable energy.
• Window improvements, replacing single-glazing with double-glazing in conditioned areas to reduce heat transfer.
• HVAC optimization, including potential future upgrades to more efficient and less harmful refrigerants, though current units are functioning well.

The proposed cost-effective scenario, combined with the rooftop PV system, offers strong financial performance and reduces the building’s environmental impact by lowering electricity consumption by 73%.

This building-level assessment is part of the broader program, where investment-grade audits and tailored measures are being proposed across all 13 buildings.

Key areas of intervention include:

• Passive strategies and air renewal improvements
• High-efficiency lighting
• High-efficiency HVAC systems with low GWP refrigerants
• Solar PV systems on-site
• Social and environmental impact assessments
• Investment cost evaluations

As we advance these initiatives in Guyana, the broader message is clear: the energy transition is not just a local endeavor—it is a global imperative. Every building retrofitted, every solar panel installed, and every efficiency measure implemented contributes to a cleaner, more resilient future for all. 

In this journey toward decarbonization, we demonstrate that sustainable development and social progress can go hand in hand, inspiring communities, governments, and industries worldwide to embrace the shift toward renewable energy. Together, we can accelerate the journey to a net-zero future, proving that thoughtful action today shapes a thriving planet for generations to come.
