A case study of the overview, process, and results of the re-tuning that was conducted in a building in Arlington, Virginia by Vornado Realty Trust in October 2012. Re-tuning provided the facilities management team with the ability to identify and understand building scheduling opportunities that drove significant, low-cost energy savings. Five measures were conducted, many of which pertained to the HVAC system.

This case study describes a successful zero energy school project in Utah.
The Sacred Heart Academy Library is part of the Sacred Heart School's Lower and Middle School campus. The library is intended as an educational demonstration of the school's goal "to teach students to be stewards of the earth's resources." The library has achieved zero energy while meeting a very modest construction budget - in fact, all Zero Energy features, including photovoltaic panels, were included within the already established budget.
Richardsville Elementary School is the first full-scale zero energy K-12 school in the United States. The school building, located in Kentucky's Warren County Public School District, uses many innovative strategies to conserve energy including dedicated outdoor air systems (DOAS) with dynamic reset, insulated concrete form (ICF) wall construction, daylighting, and ground source heat pumps, among others. The school has both thin film and crystalline silicon photovoltaic panels.

This case study presents the lessons learned from incorporating energy efficiency in the rebuilding and renovating of New Orleans K-12 schools after Hurricanes Katrina and Rita. The experiences of four new schools—Langston Hughes Elementary School, Andrew H. Wilson Elementary School (which was 50% new construction and 50% major renovation), L.B. Landry High School, and Lake Area High School—and one major renovation, Joseph A. Craig Elementary School—are described to help other school districts and design teams with their in-progress and future school building projects in hot-humid climates.
