Energy Auditing

Associated Renewable Energy Auditing

Associated Renewable is a leading energy audit and assessment company. An energy audit and energy assessment is an inspection, survey, analysis and report of energy flows to improve energy efficiency in a building. This procedure is performed by Associated Renewable’s energy audit engineers. The aim of the energy audit and energy assessment is to reduce total amount of energy used over time and to gain a comprehensive understanding of a facility’s energy usage.


An energy audit and energy assessment in a building can identify ways to reduce energy consumption while maintaining and improving human comfort. As well as identifying sources of energy use, an energy audit seeks to prioritize cost-effective energy saving opportunities.


Commercial Energy Audit

A commercial energy audit and energy assessment may involve recording various characteristics of a building including its walls, ceilings, floors, doors, windows, and electrical components. For each of these components, the area and resistance to heat flow are measured or estimated. The energy audit may also assess the efficiency, physical condition, and programming of mechanical systems such as the heating, ventilation, air conditioning (HVAC) equipment, and thermostat. The aim of this exercise is to quantify the building's overall energy performance.


A commercial energy audit will help one understand a facility’s energy use for a given time period—usually a year—and the impact of any suggested improvements. To complete the actual assessment, a billing history is required for studying the quantities of electricity, natural gas, fuel oil, or other energy sources consumed over a one-year period.


After the energy audit and assessment is completed, our training division, in partnership with Associated Renewable Institute, will educate users on altering energy use behaviors and potential energy efficiency improvements.


Types of Energy Audits

The multiple Audit levels are discussed below:


ASHRAE Level 1 Audits are less detailed energy audits that look primarily at low-cost and no-cost measures. ASHRAE Level 1 Audits typically include an energy audit of the entire building’s energy consuming equipment, a study of past utility bills, a utility audit to determine whether there are billing errors or whether there are more appropriate utility rates, an energy balance, and a determination of a list of ECMs, savings potential, and utility incentives.


ASHRAE Level 2 Audits are more detailed energy audits that look not just at simple measures that offer quicker paybacks, but also at more capital intensive measures.


Your ASHRAE Level 2 Audit will give you a list of energy conservation measures (ECMs) that will allow you to make your facility more energy efficient, determine how much each energy conservation measure will cost, and offer economic analyses that provide useful information when deciding whether to take on a project or not. The most common economic measure we present is the simple payback, which calculates how long it will take for the ECM to pay for itself. We also provide an ROI analysis and annual cash flow analysis.


Retro-Commissioning, RCx, is a detailed look at how well HVAC and lighting controls are actually working. The Energy Conservation Measures (ECMs) uncovered during RCx typically involve reprogramming controls, repairing dusty dampers, and replacing faulty actuators, valves, variable speed drives and sensors. We also take a thorough look at how building operators are using the controls, since poor operational procedures usually lead to energy waste. ECMs discovered typically are low cost or no cost. The purpose of RCx is to optimize existing system performance rather than relying on major equipment replacement (which energy audits sometimes do).


Although Retro-Commissioning (RCx) is usually more expensive and intensive than an energy audit, it typically yields better savings due to the fact that the payback is often less than 2 years.


RCx typically includes an energy audit of the entire building including a study of past utility bills and a series of interviews with facility personnel. Diagnostic monitoring and functional tests of building systems are then executed and analyzed using extensive data logging. Trending via the EMS system is also additionally performed to spot measurements of temperatures, power, static pressure, and other measures. This energy audit process helps find and repair operational problems. The identification of more complex problems is presented to the owner as well.


Our Process

Our commercial energy audit engineers will assess building envelope, heating, ventilation and air-conditioning (HVAC), lighting functions, and facility managers and staff.  Our energy audit team, in addition, considers all possible ECMs including solar and other clean energy generating systems to enhance your facility’s performance and most importantly, its value. By using Associated Renewable’s energy audit procedures, a holistic approach is generated to bring the best results to you, our client.
