1. and taking measurements to identify actual energy

 

1.    Provide the official name for each type of energy audit as per the definition of the ASHRAE standard of audits and provide a description for each type of audit. (5 points)

Type 0 – The Benchmarking Audit

·         This audit includes performing a detailed preliminary analysis of energy use

·         Comparing energy use with other buildings of the same type

·         Very cost effective when dealing with many facilities

 

Type I – The Walk Through Audit

·         This audit includes performing a walk through inspection of the facility to identify operational, deficient, or equipment issues and other areas which need further evaluation

·         Also called a “fly by” audit done in an hour or two

·         Meant to be a high level audit with limited details – no measurements!

 

Type II – The Standard Audit

·         This audit includes performing economical calculations and may include performing monitoring/testing and taking measurements to identify actual energy consumption and losses

·         Also called the energy survey and analysis audit

·         Meant to be a detailed audit with specifics

 

Type III – The Computer Simulation Audit

·         This audit includes the performance of computer modeling and simulation to determine actual year round energy consumption

·         Also called the detailed analysis of Capital intensive modifications audit

·         Level II and III can be interchangeable depending on accuracy and which auditor you speak to.

2.    What are the goals of an energy assessment? How would one go about choosing which audit level is most suitable for their building? (5 points)

·         To clearly perceive sorts and costs of energy use

·         To understand how energy is being used (and conceivably squandered)

·         To perceive and separate more clever techniques for using energy

·         In any case, the fundamental inspiration is… to play out a fiscal examination on those decisions and make sense of which plans are the most pragmatic for your business or industry.

 

To know which audit level is most suitable for their building, consider the following factors-

·         Depends on the funding available for the audit

·         Depends on the cost and potential of the energy conservation opportunities and the required accuracy

·         Depends on the type, function and processes within the facility

3.    What specific type of index is developed in a Preliminary Energy Usage analysis? Why is this index useful? (5 points)

ENERGY USE INDEX (EUI) is developed in a preliminary energy usage analysis.

The most important usage of the EUI is to measure the overall consumption of the energy and evaluate the ways of decreasing the usage of the energy with comparing EUI of one specific building with same kind of buildings and figure out the best way for reduction.

(assessment, 2018)

 

4.    Name three pre-site visit tasks one can accomplish before conducting the energy assessment. (5 points)

·         Collect and review utility energy data

·         Obtain as many drawings as possible (arch, mech, elec)

·         If possible, draw a floor plan for personal use in taking notes on-site

·         Develop a building profile that includes traits about the building such as age, occupancy, description and existing equipment/conditions of the different electrical and mechanical systems.

·         Calculate the energy use index (EUI) in BTU/sq.ft./yr. and compare it with EUIs of similar building types. This will give you a sense of how much opportunity may arise in your building
