Hospitality Property Energy Audit

Sector: Hospitality Year: 2024–2025 City: Manila, Philippines Gross Floor Area (GFA): 48,874 sqm Scope of the Mission: ASHRAE Level 2 Energy Audit with Implementation Roadmap (HVAC, Lighting, Water Heating, Electrical Systems)

Comprehensive energy audit for a two-tower mixed-use hospitality property with 362 serviced units. The project identified high-impact operational improvements and equipment upgrades to reduce energy use, improve indoor comfort, and align with sustainability goals. The recommended measures are expected to cut energy consumption by 41.9% to 53.5%, lowering the Energy Use Intensity (EUI) from 141.4 kWh/m²/year to 74.0 kWh/m²/year and achieving significant carbon reduction.

Detailed Assessment
  • Full evaluation of chiller plants, AHUs, ventilation systems, and control strategies.
  • Review of lighting, hot water systems, and electrical load control in guest rooms and common areas.
  • Identification of water conservation opportunities to reduce energy and water demand.
Performance Evaluation
  • Chiller plant optimization and control upgrades.
  • Integration of guest room key card systems with thermostats for occupancy-based cooling.
  • Automated economy mode control for corridor fan coil units.
  • Replacement of outdated AHUs with energy-efficient models equipped with advanced controls.
  • Installation of VFDs on kitchen exhaust fans and hot water pumps.
  • Water-saving fixtures for faucets and showers.
  • Motion sensor installation in corridors and lighting optimization in parking areas.
  • Electrical circuit optimization in guest rooms to disconnect non-essential loads when unoccupied.
  • Planning for future heat pump upgrades with modulating compressors for hot water systems.
Diagnostic Testing
  • Verification of control sequences for optimized chiller and ventilation operation.
  • Indoor environmental quality checks following fresh air system retrofits.
  • Continuous monitoring integration to track performance and detect inefficiencies.
Maintenance Review
  • Preventive maintenance planning for chillers, AHUs, and VFD systems.
  • Training of operational staff on optimized control systems.
  • Scheduled retrocommissioning every three years to maintain efficiency gains.
System Optimization
  • Occupancy-based cooling strategies for guest rooms and common areas.
  • Advanced control logic for AHUs and fresh air systems.
  • Load reduction through façade improvements and air infiltration control.
Efficiency Improvement
  • Estimated Annual Energy Savings: Up to 53.5%.
  • Carbon Reduction: Significant reduction in operational footprint through combined HVAC, lighting, and water system upgrades.

Result: A comprehensive and phased improvement plan enabling substantial energy and carbon reductions while enhancing guest comfort, operational reliability, and indoor air quality in a high-profile hospitality property.
