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

ASHRAE Energy Assessments

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

System Retrocommissioning

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

A European Perspective

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

Could a similar coordinated approach make sense for North American 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
