InspectionPerformance Assessed Against Design Criteria

We determine whether a building is subject to a performance inspection based on its use, gross floor area, and equipment criteria, then conduct the inspection and prepare the results report.

Target equipment
Building mechanical systems, including heat sources · HVAC · water supply and drainage · sanitary systems · automatic controls · ducts · piping
Scope of work
Design document review → Field measurement and performance testing → Performance assessment against design criteria → Identification of required improvements
Deliverables
Mechanical equipment performance inspection checklist · Performance inspection results report · Maintenance improvement recommendations
Legal Basis
Performance inspection under Article 17 of the Mechanical Equipment Act (buildings with a gross floor area of 10,000㎡ or more)
Process

Process

01

Document Review

We first review design documents and maintenance records.

02

Field Measurement

We measure actual operating data through performance testing.

03

Performance Assessment

We quantitatively assess performance against design criteria.

04

Improvement Recommendations

We prioritize items that require repair or replacement.

What we check

We compare the drawings
with actual operating data.

Even when a building is constructed to design criteria, its performance changes over time.
We use measurements to assess current performance and prioritize repairs.

Field

Inspection Sites

Air handling unit inspection — We open the unit to inspect the filter and fan condition.
Air handling unit inspection — We open the unit to inspect the filter and fan condition.
Piping and instruments — We compare pressure gauge readings against design criteria.
Piping and instruments — We compare pressure gauge readings against design criteria.
Scope

We compare design values
with current performance.

01

Equipment Performance Measurement

We measure the actual performance of heat source, HVAC, pump, and piping systems.

02

Analysis Against Design Values

We compare design performance with current performance for each system.

03

Performance Inspection Checklist

We compile and submit the findings in a performance inspection checklist and results report.

04

Heat Source System Review

We assess each system to determine whether capacity matches the load.

05

Maintenance Improvement Proposals

We identify opportunities to improve operating and control methods.

06

Improvement Priorities

We prioritize improvements by cost-effectiveness.

Difference

What makes AERO-ONE different

Conventional approach
  • Focused on completing checklist items
  • Primarily visual inspections and basic measurements
  • Ends with a list of deficiencies
  • The same deficiencies recur the following year
The AERO-ONE approach
  • Quantifies performance degradation using measured data
  • Field measurement with 24 types of in-house instruments
  • Prioritizes what to address first
  • Enables reinspection using the same criteria after improvements
FAQ

Frequently Asked Questions

Is our building subject to a performance inspection?
Under the Mechanical Equipment Act, applicable buildings must undergo regular performance inspections. Eligibility and frequency depend on the building's use, gross floor area, and equipment configuration. Send us an overview of your building, and we will first confirm whether it is subject to inspection.
How is this different from an Energy Audit?
An Energy Audit examines energy consumption and estimated savings, while a performance inspection determines whether mechanical systems deliver their design performance. When conducted together, the required measurements can be completed at the same time.
What happens if the inspection identifies noncompliance?
We document each noncompliant item, its cause, and the recommended corrective action. Items requiring reinspection after corrective action are marked separately.
