Green Construction

2. Safety procedure that shuts off and tags equipment so it can’t be restarted during work.
3. Lowering energy use first (air sealing, insulation, efficient lighting) before adding renewables.
4. Converting fractions to decimals (and vice versa) for accurate measuring and calculations.
5. NCCER Core topic: reading prints, symbols, elevations, and details to build correctly.
10. The unit for electrical resistance (how much a material resists current flow).
12. A common drawing scale where 1/4" on paper equals 1' in real life.
16. A core math skill for measuring, cutting, and sizing materials accurately.
17. Math comparison used for slope/pitch (rise:run) and layout decisions like roof pitch.
19. Area formula used to find square footage for materials like insulation, flooring, or drywall.
20. Tools/work methods designed to reduce strain and prevent injuries.
21. Low-E (low emissivity) coating on windows that reduces heat transfer while allowing light in.

1. Sorting and diverting job-site waste (metal, cardboard, concrete, wood) from landfills.
6. Reducing material use through efficient design and cutting waste.
7. Gallons per minute; measures water flow rate for fixtures and efficiency.
8. Considering total cost over time: purchase + energy + maintenance + replacement.
9. Answers with Statements
11. Energy Recovery Ventilator; brings in fresh air while transferring heat/moisture to save energy.
13. Uncontrolled outside air leaking into a building through gaps/cracks.
14. Estimating quantities from drawings (counts, lengths, areas, volumes) for materials and cost.
15. Power relationship: watts = volts × amps (used in electrical/solar calculations).
18. Safety color often used to mark hazards/alert areas (high-visibility warning).
