A Complex Engineering Puzzle
As a donor-funded non-profit, Greenstar's primary challenge was managing high operational costs, with their outdated HVAC system being a major contributor to electricity bills. The old system provided inconsistent cooling and poor air filtration, impacting employee comfort and well-being. They required a modern, cost-effective solution that would deliver a measurable return on investment, freeing up funds for their core social marketing programs.
Innovative & Efficient
We designed and implemented a high-efficiency Variable Refrigerant Flow (VRF) system throughout the corporate office. This state-of-the-art system provides granular, zoned climate control, allowing for precise temperature management in different departments and the ability to reduce power in unoccupied areas. We also integrated an Energy Recovery Ventilator (ERV) to bring in fresh, filtered air without compromising cooling efficiency, significantly improving indoor air quality. The entire system is managed via a central controller, providing detailed energy consumption data.
Key Project Outcomes
Reduced HVAC-related operational costs by over 40%, allowing for significant reallocation of funds to programmatic activities.
Substantially improved indoor air quality (IAQ), leading to a healthier and more comfortable workplace for all employees.
Achieved a projected full return on investment (ROI) in under 4 years due to massive energy savings.
Significantly lowered the organization's carbon footprint, reinforcing their commitment to social and environmental responsibility.
“Every rupee we save on operational costs is a rupee we can invest back into our health programs across Pakistan. This HVAC upgrade was a strategic decision that has yielded phenomenal savings and a much-improved work environment for our dedicated team. The project was executed with utmost professionalism and a clear focus on our objectives.”
