ista ME’s ASHRAE‑standard energy audits give you a clear baseline you can trust.

An energy audit is a structured analysis of how your building uses energy. It involves reviewing utility data, inspecting systems like HVAC, lighting, and controls, and identifying where energy is being wasted. The audit results in a report that outlines inefficiencies, recommends energy-saving measures, and provides cost and savings estimates to support decision-making.

ASHRAE stands for the American Society of Heating, Refrigerating and Air-Conditioning Engineers. It is a globally recognised organisation that develops technical standards and guidelines for building systems, energy efficiency, indoor air quality, and sustainability. ASHRAE is considered a leading authority in energy auditing, and its audit levels (1, 2, and 3) are used as international benchmarks for assessing building energy performance.

ASHRAE standards are a set of best practices and technical guidelines used worldwide to improve building performance. In the context of energy audits, the ASHRAE audit levels (1, 2, and 3) define the depth and detail of analysis—from basic assessments to investment-grade reports. These standards help ensure that audits are performed consistently, accurately, and in a way that leads to actionable, measurable energy savings.

In some sectors, yes. For example, energy audits are currently mandatory for government buildings and hotels in Dubai, and for industrial facilities in Ras Al Khaimah. Even where audits aren't yet required, they’re highly encouraged to align with the UAE’s Net Zero 2050 and Energy Strategy 2050 goals. Staying ahead of regulations today can help avoid compliance issues tomorrow.

That depends on your goals. A Level 1 audit is a quick walkthrough that identifies basic savings opportunities with minimal investment. A Level 2 audit offers a detailed building analysis, diagnostic testing, and a custom energy savings plan. For buildings planning large-scale upgrades or performance contracts, a Level 3 audit provides deep technical analysis, long-term monitoring, and investment-grade savings projections.

Savings vary depending on the building type, systems in place, and existing inefficiencies. Many clients see energy reductions of 10–30%, especially when implementing the low-cost measures identified in Level 1 or 2 audits. We also provide clear return-on-investment (ROI) estimates for each recommended action.

A Level 1 audit can typically be completed in a few days. Level 2 audits usually take 1–2 weeks depending on building complexity. A Level 3 audit is a more in-depth process that includes long-term monitoring and may take several weeks to complete. We’ll provide a clear timeline before starting any audit.

Certainly! ista is more than just an audit provider—we’re a certified Energy Services Company (ESCO) with decades of international experience and a strong local presence in the UAE. As a leading provider of smart metering and energy solutions, ista Middle East holds a unique position as both an ESCO and a utility service expert.

This dual role enables us to deliver performance-based energy efficiency projects with measurable savings, while also ensuring the accuracy, transparency, and compliance that only a metering specialist can provide. From identifying opportunities to executing the upgrades, we manage the entire process—so you see real results, not just recommendations.
