An ASHRAE Level 2 Commercial Energy Audit builds upon the preliminary findings of Level 1 by providing a detailed, data-driven evaluation of building energy performance and systems operation. This level includes in-depth utility data analysis, interval data evaluation (when available), and a comprehensive assessment of HVAC, lighting, controls, domestic hot water, and envelope performance.

Field investigations are more rigorous and include system-level inspections, equipment inventories, and operational review of sequences of operation. Energy modeling or engineering calculations are used to quantify Energy Conservation Measures (ECMs) with greater accuracy, including interactive effects between systems.

Key outputs include a refined energy baseline, ECM package with detailed technical descriptions, estimated energy and demand savings, and life-cycle cost or simple payback analysis. Measures are prioritized based on economic feasibility and implementation complexity.

ASHRAE Level 2 audits are commonly used to support capital planning, incentive/rebate applications, and informed decision-making for mid- to long-term energy efficiency upgrades.

An ASHRAE Level 3 Commercial Energy Audit provides a comprehensive, engineering-grade analysis focused on capital-intensive Energy Conservation Measures (ECMs) and long-term asset planning. This level expands upon Level 2 by incorporating detailed system modeling, submeter-level analysis where available, and calibrated energy modeling to simulate building performance under current and proposed operating conditions.

The audit includes in-depth evaluation of HVAC plant systems, distribution networks, controls optimization strategies, envelope performance, and major electrical and mechanical infrastructure. Fieldwork is more extensive, often involving additional data logging, trend analysis from building automation systems (BAS), and verification of part-load and seasonal performance characteristics.

Each ECM is developed to a design-level scope with quantified energy, demand, and operational impacts, including interactive effects across systems. Financial analysis typically includes life-cycle cost analysis (LCCA), internal rate of return (IRR), and net present value (NPV), supporting investment-grade decision-making.

ASHRAE Level 3 audits are typically used for large-scale retrofit projects, capital budgeting, performance contracting (ESCO projects), and applications requiring high-confidence savings projections and implementation-ready engineering documentation.

Rebates & Incentives Management

Smart Space manages the full lifecycle of utility rebates and tax incentives as part of the commercial retrofit process—ensuring all available funding is captured and properly executed without adding administrative burden to the building owner.

Our Process

Identification
During the ASHRAE audit, we identify all applicable rebate programs (including Georgia Power) and relevant tax incentives such as Section 179D and Modified Accelerated Cost Recovery System (MACRS) based on proposed ECMs.

Alignment
We structure recommended measures to meet program requirements and maximize eligibility across multiple incentive pathways.

Documentation
We prepare and submit all required technical documentation, including savings calculations, equipment data, and application packages.

Coordination
We handle all communication with program administrators, manage pre-approvals, and coordinate inspections or verification requirements.

Execution & Tracking
We track each incentive through approval, installation, and payout—ensuring compliance, proper sequencing, and full financial capture.
