About LEED
The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ is the nationally accepted benchmark for the design, construction and operation of high-performance energy-efficient buildings. LEED provides building owners and operators with the tools they need to have an immediate and measurable impact on the energy efficiency of their buildings. The U.S. Green Building council oversees and manages the LEED program.
There are no “LEED-certified” products. However, A. O. Smith water heaters—because of their energy-efficient technologies—can contribute to LEED certification of new residential construction projects.
LEED has separate rating systems for new commercial construction, commercial interiors,commercial core and shell, existing commercial buildings and new residential home construction.
For each rating system, LEED issues credits or points in six categories:
- *Sustainable Sites
- *Water Efficiency
- *Energy and Atmosphere
- *Materials and Resources
- *Indoor Environmental Quality
- *Innovation and Design
LEED certification provides independent, third-party verification that a building project meets the highest energy-efficient building and performance measures.

Intent
To reduce the energy consumption associated with domestic hot water by improvingthe efficiency of the water heater.
Requirements
Install an ENERGY STAR–qualified water heater (1 point), or install a solar water heaterthat, in combination with an ENERGY STAR water heater, meets at least 40% (2 points)or 60% (3 points) of the annual domestic hot water (DHW)

| Solar and LEED |
| All of our solar product qualifies for LEED IF they meet the requirement as stated below (which becomes a system efficiency calculation). Eg: if a solar preheat system is installed and has a solar contribution of 40% of the DHW load then the system gets 2 LEED points. In order to determine if there is a 40% contribution one must know total daily water usage, geographic location of the system, number of collectors, angle the collectors will be installed, collector orientation, size of solar tank, and type and size of secondary or backup heating. In order to qualify for points a system model must be completed per job with the output being the total solar contribution. |
Solar Water Heaters (backup)
Greater than or equal to 40% of annual DHW load - With preheat tank 2 pts
Greater than or equal to 60% of annual DHW load - With preheat tank 3 pts |
* Energy Factor on Hybrid Electric Heat Pump models is when the unit is in Hybrid Mode
