Study Notes

Energy Saving Measures

Building envelope improvements can achieve energy savings of 10-20%.
High investment measures include:
- Equipment upgrades to high-efficiency chillers and motors.
- System changes, such as cogeneration, which can provide savings over 20%.
- Implementation of thermal storage and District Cooling Systems (DCS).
- Establishment of Building Automation Systems (BAS) for monitoring.

Energy Audit Methodology

Steps include:
- Preliminary data evaluation and desktop analysis.
- Installing audit equipment for data collection.
- On-site energy usage analysis to assess existing equipment efficiency.
- Data analysis to identify findings and recommendations.

Energy Efficiency Technologies

Solar PV systems advocated under Power Purchase Scheme or Net Energy Metering (NEM).
Transition to high-efficiency LED lighting can yield savings of 75-80%.
Intelligent control systems for chillers can optimize energy use.
Introduction of an Energy Management System (EMS) helps track and manage consumption.

Electric Vehicle Infrastructure

Promoting energy monitoring via TNBX EMS.
Electric Vehicle (EV) charging infrastructure recommended through TSG partnership.

Energy Audit Insights

Energy audits reveal consumption patterns and highlight savings opportunities.
Key outputs include:
- Energy consumption trending and daily load profiles.
- Load apportioning to identify areas for energy reduction.

Cost Saving Strategies

Investment influences potential savings:
- Low-cost measures (3-10% savings) include tuning building services, user awareness, and maintenance.
- Medium-cost measures focus on cooling system improvements and efficient equipment upgrades.

Financing and Performance Assurance

Energy Performance Contracts (EPC) offer:
- No upfront capital or operational costs.
- Zero financial risk for customers with guaranteed savings.
- Expert advisory on optimal investments and operation and maintenance done by providers.

Financial Impact

Savings result from reduced energy consumption and demand.
Key financial metrics focus on decreasing kilowatt usage, maximum demand charges, and maintenance costs.
