Organizations often lack a clear, facility-specific understanding of where energy is being consumed and which improvements will deliver meaningful results.

Common challenges include:

Operational Performance Gaps

Limited insight into how building systems are performing in practice

Implementation & Financial Risks

Difficulty prioritizing efficiency measures across multiple facilities

Portfolio Management Challenges

Uncertainty around expected savings, costs, and implementation complexity

Capital Planning & Budgeting

Need for defensible analysis to support funding, budgeting, and capital planning

Detailed energy assessments provide a structured, data-driven foundation for identifying, evaluating, and prioritizing energy efficiency opportunities.

Scalable Solutions for Every Building

SustainErgy applies a tiered assessment approach aligned with recognized industry standards, allowing the level of detail to match project objectives, building complexity, and available data.

We gather available utility data, drawings, equipment information, and operational inputs, supplemented by site observations where required.

Major energy-using systems—such as HVAC, lighting, envelope, and plug loads—are reviewed to understand operating conditions and performance characteristics.

Potential energy conservation measures are identified based on observed conditions, operating patterns, and applicable best practices.

Measures are evaluated at a level of detail appropriate to the assessment type, considering energy impact, cost, and feasibility.

Findings are organized into a clear, structured format to support decision-making, funding applications, and next-step planning.

Service Scope & Outputs

The scope and outputs of a Detailed Energy Assessment vary based on the required level of analysis, ranging from high-level screenings to investment-grade studies.

Typical scope and outputs may include:

Data Benchmarking

Review and analysis of historical utility consumption

On-Site Inspection

Site walkthroughs and system observations, where applicable

Opportunity Discovery

Identification of energy conservation measures (ECMs) across building systems

Strategic Scope

Order-of-magnitude to detailed estimates of energy, cost, and GHG impacts

Impact Quantification

Consideration of operational improvements and capital retrofit opportunities

Standardized Methodology

Alignment with recognized assessment frameworks (e.g., ASHRAE Levels 1, 2, and 3)

Actionable Reporting

Clear summary reporting suitable for internal review, funding submissions, and capital planning
