On-site engineer analyzing facility energy systems with digital monitoring tools
With increasing pressure to reduce operational costs and meet decarbonization targets, facility owners are turning to structured energy efficiency solutions. One of the most effective starting points is through ASHRAE energy audits, especially Level 1 and Level 2, which provide actionable insights and how to convert them into sustainable strategies that drive efficiency, cost reduction, and savings.
Let’s explore how these audits dive deep into a building’s energy infrastructure and reduce carbon footprint to accelerate the shift towards net zero.
Understanding ASHRAE Level 1 and Level 2 Audits
An ASHRAE energy audit is a comprehensive assessment of a building’s energy usage, designed to identify opportunities for efficiency improvements. It adheres to defined standards for calculating potential energy savings, reductions in greenhouse gas emissions, cost benefits, and the expenses involved in implementing energy saving measures.
Level 1: Walkthrough Audit
A rapid assessment of energy usage patterns, operating conditions, and instant low-cost or no-cost solution ideal for identifying quick wins and raising awareness.
Level 2: Energy Survey and Analysis
A deeper look into utility bills, equipment-level performance, and load profiling. This level includes preliminary financial analysis to evaluate payback periods on retrofits or control upgrades.
These audits form the foundation for any energy efficiency journey and also provide the insights needed for the decision-makers on where to focus their efforts for the greatest impact.
Turning Audits into Action: Structured Implementation
By categorizing audit recommendations into immediate, medium-term, and long-term strategies, organizations can create a clear and actionable roadmap for improving energy efficiency.
We help in bridging the gap between insight and impact by aligning audit results with staged implementation and energy management plans:
Immediate Actions (Post-Level 1)
- Adjusting temperature setpoints
- Detecting equipment scheduling conflicts
- Introducing AI energy management pilots
Targeted Measures (Post-Level 2)
- Implementing VFD energy savings on pumps and fans
- Optimizing demand-side energy optimization strategies
- Deploying energy analytics software to monitor critical systems
These stages help reduce Scope 1 and 2 emissions and support measurable energy savings for businesses.
Role of Technology in Post-Audit Implementation
- Load profiling based on zone-level data
- Fault detection for all utility equipment
- Alerts on overcooling and bypass valve misuse
This synergy allows facility managers to take immediate actions by turning audit insights into measurable decarbonization solutions.
Driving Results Through Intelligent Optimization
- Quick deployment of climate tech for buildings
- Targeted HVAC energy optimizations
- Scalable, modular solutions aligned with budget and goals
Even without deep retrofits, buildings can cut 7–30% of energy use which is an impactful step towards net zero buildings.
Final Insights
ASHRAE Level 1 and 2 audits are strategic tools towards the decarbonization journey. They reveal where you stand and point directly to opportunities for real-world improvement using energy efficiency solutions, smart technologies, and a clear understanding of your building’s energy profile.
Delaying the implementation of projects after a building energy audit can lead to substantial financial setbacks. Every day of inaction leads to forfeited savings and escalating operational expenses. As technology continues to advance, postponing improvements may require additional upgrades later, driving up both costs and implementation challenges.
