How can you compare ASHRAE Level 1, 2, and 3 energy audits?

In my experience, there are several types of energy audits: walk-through energy audits, target energy audits, and detailed energy audits. 1. Walk-through energy audit: consists of collecting and analyzing all related and relevant data with no or low-cost, The goal of an ASHRAE Level 1 audit is to identify glaring areas of energy inefficiency. All gathered data is then compiled into a report detailing no- or low-cost changes that can be made to the building, as well as other potential capital improvements earmarked for further study.

A auditório nível 1 pode ser de grande valia quando os gestores n?o conhecem o estado atual de eficiência da sua planta, tampouco as tecnologias empregadas nos usos finais de energia, tornando-se o primeiro passo de melhoria e oportunidades.

Level 1 audits are a starting point, not a comprehensive solution. According to The Impact of ASHRAE Level 1 Energy Audits on Building Energy Performance study published in Energy and Buildings (2017), analyzed the energy savings achieved after implementing recommendations from Level 1 audits. The study found that average annual energy savings ranged from 5% to 15%. ASHRAE Level 1 Energy Audits are ideal for: o Small to medium-sized buildings. o Initial assessment before considering further investment. o Budget-conscious situations.

One time at work, in my experience, I found Level 1 energy audits to be like that first cup of coffee in the morning – simple yet essential. They offer a sneak peek into energy usage, paving the way for smarter decisions. Think of it as a gentle nudge towards a greener tomorrow. One thing I have found helpful is how these audits provide a clear starting point, much like a roadmap, guiding us towards sustainable practices. So, if you're looking to make a meaningful impact without breaking the bank, consider starting with a Level 1 energy audit. Your wallet and the planet will thank you

? Level 2 audits are more accurate and detailed than Level 1, but also more expensive. Studies suggest Level 2 audits can identify ECMs leading to 20-40% energy savings in buildings.

The level two energy audits takes the data collection and final reporting made during level 1 a step farther. It consist mainly to break down the energy consumption in the important buildings to identify the areas with the greatest opportunity to improve the energy efficiency and cost reduction and to define the financial and non-financial goals for the audit. Generally, we start by the classification of the necessary actions to be done according to their amplitude and their financial cost. A Level 2 audit provides enough data to justify the implementation of a projects.

In my experience, the L-03 Study is an in-and-out study of equipment that encompasses static & and variable factors affecting significant energy usages,

Level 3 audits, also known as Investment-Grade Audits, delve into the deepest depths of building energy analysis. Unlike Level 1 and 2, they focus specifically on complex and expensive modifications requiring rigorous financial justification. they are ideal for significant capital investments, offering detailed justification and risk assessment Studies by Lawrence Berkeley National Laboratory (LBNL) and others show that Level 3 audits can lead to 30-50% energy savings depending on the project scope and implemented measures.

Level 3 audits are for those businesses that have Level 3 audit: Already completed a Level 2 audit, has identified capital cost projects that it wants to undertake, but needs more data before making that size of an investment. Making a detailed balance to compare energy and operating savings both pre- and post-implementation of each energy amelioration project.

Start with Level 1 for a quick assessment and basic improvements. Move to Level 2 for detailed analysis and potential for significant savings. Use Level 3 for justifying large investments requiring comprehensive financial and risk assessment.

A study by the National Institute of Building Sciences found that proactive maintenance based on energy audits can save buildings 25-30% on energy costs and reduce maintenance costs by 10-20%; A study by the World Health Organization (WHO) found that poor indoor air quality contributes to over 4.2 million deaths annually worldwide. Energy audits can promote better ventilation and healthier indoor environments. A Lawrence Berkeley National Laboratory (LBNL) study found commercial buildings implementing audit-identified measures achieved an average 23% annual energy savings.

A successful energy audit is a collaborative effort. By involving key stakeholders, setting clear goals, and utilizing thorough analysis and planning, you can unlock significant energy and cost savings while contributing to a more sustainable future. Consider a pre-audit: A preliminary assessment can help refine your goals and prioritize areas for detailed investigation. Engage employees: Encourage employee participation and awareness to promote behavioral changes that contribute to energy savings. Seek financial incentives: Explore government grants, rebates, or tax deductions available for energy efficiency upgrades. Start small and scale up Continual improvement

several components are involved to develop properly an EE project. However, in practice, the potential stakeholders focus on the "Energy Audit". Auditing is only the first step in EE development project! "EE savings and Capital Costs" must imperatively be supported by an Investment Grade Audit (IGA) and measurement and verification plan (M&V) properly prepared to create trust and provide finance for the project.

ASHRAE Level 1, 2, and 3 energy audits differ in their depth and scope: Level 1: Focuses on preliminary analysis, identifying low-cost and no-cost energy-saving opportunities through a walkthrough assessment. Level 2: Provides a more detailed energy analysis, including energy usage data analysis and simple payback calculations for energy conservation measures. Level 3: Involves a comprehensive energy analysis, utilizing detailed energy modelling and investment-grade cost estimates for potential energy efficiency upgrades.

I think it boils down to an commercial or industrial facility or campus energy audit ranging from PEA, walk thru to investment grade, what else is there other than ASHRAE 1,2,3 framework that banks or other commercial paper writers will accept? So, comparing to what else seems a reasonable question?
