What is an energy audit ?
The term energy audit is commonly used to describe a broad spectrum of energy studies ranging from a quick walk through of a property to identify major problem areas to a comprehensive analysis using sophisticated survey equipment. Evolved Energy Solutions have provided surveys for clients that have ranged from single day site inspections to long terms projects where we provide ongoing consultancy aswell as project management of upgrades.
Once completed an energy audit provided by Evolved Energy Solutions will contain a list of suitable upgrades. See the video below for an example review process following an energy audit.
Energy Audit Review.
Preliminary audit Level 1 audit
After reviewing your energy audit report, you will have a sufficient level of information enabling you to proceed with suitable upgrades. Evolved Energy Solutions provide a complete follow on service in the area of project management and tender documentation provision for larger upgrade projects. We can remain involved as expert, independent advisers to all our clients. This ensures your energy upgrade works are completed to the highest standards and that project control remains in the clients hands.
General Audit Level 2
The general energy audit expands on the preliminary audit
described above by collecting more detailed information about facility operation and by performing a more detailed evaluation of energy conservation measures. Utility
bills are collected for a 12 to 36 month period to allow the auditor to evaluate the facility's energy/demand rate structures and energy usage profiles. If interval
meter data is available, the detailed energy profiles that such data makes possible will typically be analyzed for signs of energy waste. Additional energy metering of specific energy-consuming systems is
often performed to supplement utility data. In-depth interviews with facility operating personnel are conducted to provide a better understanding of major energy
consuming systems and to gain insight into short and longer term energy consumption patterns.
This type of audit will be able to identify all energy-conservation measures appropriate for the facility, given its operating parameters. A detailed financial analysis
is performed for each measure based on detailed implementation cost estimates, site-specific operating cost savings, and the customer's investment criteria.
Sufficient detail is provided to justify project implementation.
The advent of high resolution thermography has enabled inspectors to identify potential issues within the building envelope by taking a thermal image of the
various surfaces of a building. For purposes of an energy audit, the thermographer will analyze the patterns within the surface temperatures to identify heat
transfer through convection, radiation, or conduction
In most corporate settings, upgrades to a facility's energy infrastructure must compete for capital funding with non-energy-related investments. Both energy and
non-energy investments are rated on a single set of financial criteria that generally stress the expected return on investment (ROI). The projected operating savings
from the implementation of energy projects must be developed such that they provide a high level of confidence. In fact, investors often demand guaranteed
The investment-grade energy audit (alternatively called a comprehensive energy audit, detailed energy audit, maxi audit, or technical analysis audit) expands on the general energy audit
described above by providing a dynamic model of energy-use characteristics of both the existing facility and all energy conservation measures identified. The building
model is calibrated against actual utility data to provide a realistic baseline against which to compute operating savings for proposed measures. Extensive attention
is given to understanding not only the operating characteristics of all energy consuming systems, but also situations that cause load profile variations on short and
longer term bases (e.g. daily, weekly, monthly, annual). Existing utility data is supplemented with submetering of major energy consuming systems and monitoring of
system operating characteristics.
