ENERGY EFFICIENCY
DISTRICT COOLING SYSTEM
TOSL have implemented a low carbon energy efficient District Cooling Project utilizing 100% ozone friendly refrigerants to cool our offices. This enables us to reduce our power / electricity consumption used for cooling and as a result, reduce our carbon footprint. Our district cooling system was commissioned in Q3 2024 and is fully operational. Our services have expanded to replicate this project to office buildings within our region.
- Centralized cooling solutions for large facilities
- Solar-powered district cooling systems
- Energy-efficient chillers and thermal storage
ENERGY AUDITS
We are currently conducting an energy audit on our buildings to further improve our energy savings and support our sustainability goals. The scope of this venture proves that we are committed and show that we understand the importance to start at “home”. Our expanded services to industries and businesses include experienced, thorough and professional assessments to identify energy consumption patterns, inefficiencies, and areas for improvement. Through detailed analysis, we provide actionable recommendations to reduce energy use, lower operational costs, and minimize environmental impact. From energy-saving solutions such as insulation upgrades to more efficient heating, ventilation, and air conditioning (HVAC) systems, we ensure that buildings operate at optimal efficiency. TOSL Engineering Limited’s energy audits are tailored to meet the specific needs of each client, delivering customized strategies that improve energy performance and contribute to long-term sustainability.
