Energy Assessor

An energy assessor looks at the plans and details for a brand-new building—like a house or school—and uses special rules called “building regulations” to see if it will use energy wisely. Instead of visiting an existing building, they work on paper and computer models to predict how much heating, cooling, and electricity the new building will need. If something doesn’t meet the rules, they suggest changes so the building will be energy-smart before it’s even built.

What tools do you use to do your job?

• Building plans and specifications: Drawings and written details that show how walls, windows, doors, roofs, and heating systems are built.
• Energy-modelling software: A computer program that takes the plan details and calculates how much energy the building will use.
• Calculator: To double-check numbers and make sure the software results are correct.
• Building regulations guide: A rulebook that tells you how efficient walls, windows, and heating systems must be.
• Computer or laptop: To run the software, store the plans, and write up your assessment report.

What makes a good energy assessor?

• Detail-spotter: Notices tiny things in plans—like small windows or thin walls—that affect energy use.
• Math whiz: Loves working with numbers and calculations.
• Rule-follower: Knows the building regulations inside out and never misses a requirement.
• Clear explainer: Can describe complicated rules in simple words so architects and builders understand what to change.
• Problem solver: Thinks of smart ideas—like thicker insulation or better windows—when something doesn’t meet the rules.

What do you do each day?

1. Check your schedule: See which building plans you need to assess today.
2. Open the plans: Study the drawings and written details carefully.
3. Enter data into the software: Type in measurements for walls, roofs, windows, doors, and heating systems.
4. Run the energy model: Let the computer program predict how much energy the building will need each year.
5. Compare with the rules: See if the model results meet all parts of the building regulations.
6. Note any failures: Mark the parts that don’t pass—maybe the windows let in too much cold or the walls aren’t insulated enough.
7. Write your report: Explain in simple language what meets the rules and what needs to change.
8. Send feedback: Email or present your report to the architect or builder so they can update the plans.

By doing these steps, an energy assessor helps make sure new buildings will be warm in winter, cool in summer, and kind to the planet—all before a single brick is laid!
