Airports are inherently high consumers of energy:
Steps to Optimizing Performance
• Define Baseline Performance (Benchmark)
• ASHRAE Level 1, 2 or 3 Energy Assessments
• System Retro-commissioning
Level 1• Walk-Through Audit (Least cost
intensive option)
• Energy Baseline, Systems Description, Measure identification
• Helps Narrow the Focus
Level 2• Detailed Audit
• In depth analysis of building performance, including envelope, HVAC and lighting systems
• Avoided energy costs through implementation of ECMs
Level 3• Investment grade audit (Most cost
intensive option)
• Typically utilizes a energy model to more accurately determine synergistic effects of energy conservation measures
• Provides greater accuracy when deciding on ECM measures
Planning• Identify buildings to be included
in study – Define the scope
• Baseline energy performance (typically 9 months)
• Identify HVAC points to be trended and begin recording data
Investigation• Visit site, assess building operation
and profile energy consuming equipment
• Analyze system trend data and identify opportunities for optimization
• Calculate potential avoided costs & prioritize implementation measures
Implementation• Implement energy
Retrocommissioning measures
• Record implementation strategies and update O&M manuals
Hand-off• Measure savings from baseline
period
• Identify whether implemented measures reflect investigation recommendations
• Identify opportunities to maintain savings moving forward
CASCADE Research Project• Funded by the EU
• Lead Research Group - Fraunhofer
• Utilizing Building technology to identify system inefficiencies at Airports
• Targeted 20% reductions in energy and GHG emissions
• 3 year payback period
• Goal is to role this program out over all European Airports
The Process• Benchmark 60 EU airports for energy
• Select two candidates for participation
• Building Systems Retrocommissioned
• Energy upgrade projects implemented
• Building performance “Normalized”
• Implement FDD and ISO50001 process at these airports
The Potential Benefits• Airports have unique operational
requirements
• Ability to share data will only enhance energy savings potential
• Best practices can be established
• Could result in a more coherent and targeted approach to EM at airports
