Applicable to:
- Cities and Utilities (1–3 points)
- Campuses (1–4 points)
- Transit (1-4 points)
INTENT
To encourage investments that optimize hourly demand loads and reduce both project costs and environmental impacts.
REQUIREMENTS
All Projects
Calculate the project’s annual hourly demand for one year, in kW, for all major loads served, including customer meters and central cooling and heating. Determine the annual load duration as a percentage of peak using the following formula:
Where:
EConsumed = Total annual electricity consumption of project in kWh
Dpeak = Project peak annual electric demand in kW
8,760 = Hours per year
Points are awarded according to Table 1.
Table 1. Points for load duration curve optimization
Load Duration (% of peak) | Points | |
Cities & Utilities | Campuses & Transit | |
≥ 25 | 1 | |
40 | 2 | 1 |
55 | 3 | 2 |
70 | 3 | |
85 | 4 |
Projects that achieve a load duration percentage of peak higher than 70% (cities and utilities) or 90% (campuses and transit) earn 1 additional point for exemplary performance under the Innovation credit category.
