with correct answers
___ is the ratio of a project's financial gain to its cost after a certain length of time. CORRECT ANSWER Return on investment (ROI) The end of the payback period is the point when the ROI equals ___%. CORRECT ANSWER 100% A(n) ___ energy audit is an energy-use study that involves only an overview of a building's major energy-consuming processes. CORRECT ANSWER preliminary ___ data is data that represents a normal operating state and is used as a point of reference for future changes. CORRECT ANSWER Baseline ___ compares the energy use of homes and facilities with other buildings in the United States that have similar characteristics. CORRECT ANSWER Benchmarking Generally, buildings with older and larger equipment realize larger savings and ___ payback periods. CORRECT ANSWER shorter The energy efficiency of ___ is typically beyond the scope of the building audit. CORRECT ANSWER processes The ___ lists the tasks to be completed, such as requesting bids and ordering equipment. CORRECT ANSWER action plan
Complete follow-up audits should be conducted ___ to verify expected energy use and identify long-term trends toward inefficiency. CORRECT ANSWER at periodic intervals ___ maintenance is the scheduled work required to keep equipment in peak operating condition. CORRECT ANSWER preventive Benchmarking CORRECT ANSWER The process of comparing the performances of different systems that have similar purposes. payback period CORRECT ANSWER The time elapsed until a project's resulting savings equals its costs. preliminary energy audit CORRECT ANSWER An energy-use study that involves only overview of a building's major energy-consuming processes. baseline data CORRECT ANSWER Data that represents a normal operating state and is used as a point of reference for future changes. return on investment (ROI) CORRECT ANSWER The ratio of a project's financial gain to its cost after a certain length of time. investment-grade energy audit CORRECT ANSWER An energy-use study that requires a comprehensive set of measurements and records and involves developing a dynamic model of the building's energy-use characteristics. preventive maintenance CORRECT ANSWER The scheduled work required to keep equipment in peak operating condition.
Generally, buildings with older and larger equipment realize larger savings and shorter payback periods. CORRECT ANSWER true In energy auditing, benchmarking compares the energy use of homes and facilities with other buildings in the United States that have similar characteristics. CORRECT ANSWER true The energy efficiency of a process is typically included in the scope of a building audit. CORRECT ANSWER false The most difficult part of calculating potential savings is estimating the new energy use information for the modified system. CORRECT ANSWER true On a project summary, the low-ROI items are typically listed first, unless there are other factors that affect their importance, such as safety or comfort. CORRECT ANSWER false Complete follow-up audits should be conducted at periodic intervals to verify expected energy use and identify long-term trends toward inefficiency. CORRECT ANSWER true The most obvious benefit of improved energy efficiency is ___. CORRECT ANSWER reduced utility costs ___ systems are typically the largest energy consumers and are also important to the safety and comfort of building occupants. CORRECT ANSWER Lighting and HVAC ___ is the ratio of a project's financial gain to its cost after a certain length of time. CORRECT ANSWER Return on investment (ROI)
The end of the ___ is the point when the ROI equals 100%. CORRECT ANSWER payback period ___ equipment has higher costs, but the payback period is usually less than a year. CORRECT ANSWER Repairing A(n) ___ energy audit can only uncover the most obvious energy waste or inefficiency problems. CORRECT ANSWER preliminary A(n) ___ energy audit identifies and prioritizes appropriate energy conservation and efficiency measures, including implementation cost estimates, site-specific operating cost savings opportunities, and customer investment criteria. CORRECT ANSWER general A general energy audit requires a record of utility bills over a ___ period. CORRECT ANSWER 12-month to 36-month ___ data is data that represents a normal operating state and is used as a point of reference for future changes. CORRECT ANSWER Baseline ___ is the process of comparing the performances of different systems that have similar purposes. CORRECT ANSWER Benchmarking An audit ___ involves the inspection of each system within the scope of the audit. CORRECT ANSWER investigation
A(n) ___ energy audit is an energy-use study that requires a comprehensive set of measurements and records and involves developing a dynamic model of a building's energy-use characteristics. CORRECT ANSWER investment grade Present energy use is quantified as ___ data. CORRECT ANSWER baseline Cost-effectiveness is based on the ratio of ___ to implementation cost. CORRECT ANSWER savings Audit report ___ include explanations of the savings opportunities, supporting data, rationale for estimation methods, calculations, project tasks and schedules, a breakdown of implementation costs, and any other factors that must be considered. CORRECT ANSWER project details For some buildings, a comprehensive ___ audit is performed when all initial implementation projects are complete. CORRECT ANSWER follow up
