Objective:

To allocate utility costs (electricity, water, and gas) fairly between residential, retail units and common areas, ensuring transparency and accurate billing.

Scope of Work:

1. Data Collection:
• Gather historical utility bills (electricity, water,) for the entire building for at least 12 months.
• Collect floor plans, unit areas, and tenancy details for both residential and retail spaces.
• Identify major equipment serving each zone (HVAC, lighting, pumps, etc.) and their operational schedules.
2. Consumption Analysis:
• Analyse total utility consumption and identify trends or anomalies.
• Determine baseline consumption for common areas shared by residential and retail units.
• Estimate utility usage for each unit type (residential vs retail) using suitable allocation methods.
3. Allocation Methodology:
• Develop a fair and transparent methodology for splitting utility costs between residential and retail units.
• Consider factors such as:
• Unit area or square footage
• Operational hours (e.g., retail longer hours than residential)
• Type of equipment and energy demand
• Adjust for any special cases or high-consumption tenants.
4. Reporting:
• Provide a detailed report showing:
• Total building utility consumption
• Allocated consumption and cost for residential units
• Allocated consumption and cost for retail units
• Allocated consumption and cost for common areas.
• Methodology and assumptions used for allocation
• Recommendations for future metering or monitoring improvements to improve accuracy.

Deliverables:

• Utility Allocation Report with detailed calculations
• Graphical representation of consumption trends
• Recommendations for fair billing and energy efficiency improvements
