Performance Highlights

ENERGY CONSUMPTION Total energy consumption decreased from 1,069,792 kWh in FY 2023 to 983,094 kWh in FY 2025, driven by lower electricity and fuel usage across our operations. EFFICIENCY GAINS A Level 1 Energy Audit by Prodesign, an external auditor, highlighted low-cost, actionable improvements: • Switch off appliances when idle • Staff awareness campaigns on energy efficiency • Keep doors/windows closed while the air conditioning is operating • Install signage to encourage lights off and the use of daylight • Fit occupancy sensors in toilets DIESEL MONITORING A diesel meter was installed on the backup generator, enabling more precise monitoring and better management of fuel consumption.

FRESH AIR SYSTEM A fresh air system was introduced at Cim House to improve indoor air quality and employee wellbeing. By providing a continuous flow of filtered air in a largely air-conditioned building, the system reduces pollutants, improves comfort and productivity, and supports a healthier workplace. Early projections suggest up to a 5% reduction in electricity use if implemented alongside complementary air-conditioning policies. INDOOR AIR QUALITY An Indoor Air Quality (IAQ) assessment was carried out at Cim House to evaluate ventilation efficiency and identify potential sources of chemical pollutants. It focused on CO₂ and total volatile organic compounds (TVOC) in line with the ASHRAE Standard 62.1 and WHO guidelines: • TVOC: All 20 sampling points were well below the recommended limit of 500 μg/m³ (250 ppb), showing effective control of chemical pollutants. • CO₂: Certain office areas exceeded the ASHRAE limit of 1,000 ppm. Increasing air change rates in these areas is recommended to improve ventilation and maintain healthy indoor air quality.
