Distinguish source energy and test a revised fuel mix
See this course’s project requirements
A fictional building-energy brief with source/unit checks, whole-year site energy, floor-area intensity, fair comparison limits, anomaly questions and an evidence-based monitoring proposal.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Save audited annual energy inventory and excluded-meter list; include the original-case decision evidence and a separate changed-case result.
- Save fuel-specific conversion ledger and site total; include the original-case decision evidence and a separate changed-case result.
- Save site EUI with boundary/period/no score label; include the original-case decision evidence and a separate changed-case result.
- Save bounded building comparison and needed peer data; include the original-case decision evidence and a separate changed-case result.
- Save source/site scenario comparison with factor limitations; include the original-case decision evidence and a separate changed-case result.
- Save building energy inventory/conversion/EUI/source/comparison brief; include the original-case decision evidence and a separate changed-case result.
Review and revise
Use these criteria to check your work and choose what to improve.
- The final packet uses the supplied task-specific constraints and all six records agree.
- Every result can be traced to an identifier, input, calculation or stated decision rule.
- Changed-case practice updates dependent records and keeps holds or uncertainty visible.
- The packet states the learner role, authority boundary and specific next verification needed before real work.

The idea in everyday life
Original fictional workplace practice; paper or a local document is sufficient. The rules and records below are supplied for this exercise, not asserted universal workplace policy. Aspen A electric 682,400/gas 600,000 site kBtu . Illustrative fictional source factors electric 2.8, gas 1.05. Compute branch sources; not official Portfolio Manager factors. Alternative electric 614,160/gas 650,000 site kBtu shifts fuel mix.
Source energy uses factors for upstream generation/delivery and therefore can rank fuel mixes differently; supplied factors must be labeled scenario inputs, not current official conversion rules.
Distinguish source energy and test a revised fuel mix — worked practice
Source energy uses factors for upstream generation/delivery and therefore can rank fuel mixes differently; supplied factors must be labeled scenario inputs, not current official conversion rules.
Aspen A electric 682,400/gas 600,000 site kBtu . Illustrative fictional source factors electric 2.8, gas 1.05. Compute branch sources; not official Portfolio Manager factors. Alternative electric 614,160/gas 650,000 site kBtu shifts fuel mix. Use paper or a local document. Preserve the original case and make a separate changed-case record.
1. Step 1
Apply illustrative source factors to each baseline fuel branch.
You should see: Electric 1,910,720; gas 630,000.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
2. Step 2
Add baseline source and divide by area 20,000.
You should see: 2,540,720 source kBtu ; source EUI127.036.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
3. Step 3
Calculate new site fuel total without source factors.
You should see: 614,160+650,000=1,264,160 site kBtu .
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
4. Step 4
Save source/site scenario comparison with factor limitations.
You should see: New site saving 18,240 kBtu ; source factor results are illustrative, not certification.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
What to finish
Save source/site scenario comparison with factor limitations; include the original-case decision evidence and a separate changed-case result.
Watch for this
Presenting fictitious source factors as official or assuming a lower electric quantity means all fuel energy fell.
How can I tell I understand it?
Using the supplied identifiers, I can save source/site scenario comparison with factor limitations. My changed-case record names the revised condition and explains which dependent decision it changes.
