Earn 1 point for every 4% decrease in conditioned floor area compared with the ENERGY STAR for Homes, version 3, reference home (Table 1). Buildings that are larger than the reference home lose 1 point for every 4% increase in conditioned floor area.
Projects cannot exceed the maximum number of points in the EA section.
Table 6. Conditioned floor area of reference home, by number of bedrooms
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 or more | |
| Floor area (square feet) | 1,000 | 1,600 | 2,200 | 2,800 | 3,400 | 4,000 | 4,600 | + 600 ft2 per additional bedroom |
| Floor area (square meters) | 93 | 148 | 204 | 260 | 315 | 371 | 427 | + 55 square meters per additional bedroom |
