Interworld Companies is currently developing pilot programs for facilities interested in obtaining LEED Certification for their existing buildings. By bringing together key stakeholders in the community, Interworld will provide LEED advisements to promote a program to reduce energy, costs, and improve the quality of life for occupants in your facility.

In 2000, USGBC established the LEED rating system as a way to define and measure “green buildings.” In school terms, LEED is like a report card for buildings, demonstrating to the community that a facility is built and/or operated in a way that supports the health and wellbeing of occupants and saves energy, resources, and money. LEED certification is available for both new and existing schools. The LEED rating system is an internationally recognized certification system that measures how well a building performs according to several metrics:

– energy savings
– water efficiency
– CO2 emissions reduction
– improved indoor environmental quality
– stewardship of resources

Types of Credit Requirements

There are three types of improvements addressed through the LEED for Existing Buildings:

O&M rating system:

High-Performance Building Systems:

Implement building improvements and technologies in order to use less energy, less water, and fewer natural resources. System upgrades and retrofits also improve indoor air quality and address operational inefficiencies. Examples: Efficient lighting systems and indoor plumbing fixtures. These improvements relate directly to the school facility being certified.

O&M Best Practices:
Adopt operations and maintenance best practices to ensure project measures are effectively implemented and maintained.
Examples: Systems monitoring, green cleaning, and preventative maintenance procedures. Schools or school districts can treat the project pursuing certification as a pilot for the adoption of new best practices to be implemented campus- or district-wide.


Sustainable Policies:
Establish green policies to demonstrate an organization-wide commitment to sustainability.
Examples: Policies to guide recycling programs and the use of eco-friendly products.
These types of requirements lend themselves to campus- or district-wide adoption and implementation.
