Momentum behind zero energy building design and construction is increasing, presenting a tremendous opportunity for advancing energy performance in the commercial building industry. At the same time, there is a lingering perception that zero energy buildings must be cost prohibitive or limited to showcase projects. Fortunately, an increasing number of projects are demonstrating that high performance can be achieved within typical budgets. This factsheet highlights replicable, recommended strategies for achieving high performance on a budget, based on experiences from past projects.

There is mounting evidence that zero energy can, in many cases, be achieved within typical construction budgets. To ensure that the momentum behind zero energy buildings and other low-energy buildings will continue to grow, this guide assembles recommendations for replicating specific successes of early adopters who have met their energy goals while controlling costs. Contents include: discussion of recommended cost control strategies, which are grouped by project phase (acquisition and delivery, design, and construction) and accompanied by industry examples; recommendations for balancing key decision-making factors; and quick reference tables that can help teams apply strategies to specific projects.
A solar ready building is engineered and designed for solar installation, even if the solar installation does not happen at the time of construction. The solar ready design features, if considered early in the design process, are typically low or no cost. Attention to building orientation, available roof space, roof type, and other features is key to designing solar ready buildings.
A detailed two page case study on the Zero Energy Ready Turkey Foot Middle School.
"Turkey Foot is revolutionizing the way kids learn, all within a new building that uses half the energy of the previous school despite being twice the size. Turkey Foot leveraged the practices and experience on other high performance goals in the District."
A detailed two page case study on the Zero Energy Ready Redding School of the Arts in Redding, CA.
"In 2011, the charter school opened a new facility with an ambitious goal of zero net energy, while dedicating only 2% of the budget to renewable energy systems."
The driver for this small school to become zero energy started with a sustainability ethic based on the Quaker values of simplicity and stewardship. This school is an excellent example of rural schools.
This guide provides user-friendly guidance for achieving a net zero energy K-12 school building. It includes a set of energy performance targets for all climate zones. Strategies on how to achieve these energy targets are provided throughout the guide and include setting measurable goals, hiring design teams committed to that goal, using energy simulation throughout the design and construction process, and being aware of how process decisions affect energy usage.
The how-to tips address specific project aspects-building and site planning, envelope, daylighting, electric lighting, plug loads, kitchens and food service, water heating, HVAC, and renewable energy generation. Each section contains multiple tips that move the design incrementally toward the zero energy goal. Case studies and technical examples show how the energy goals are achievable at typical construction budgets as well as demonstrate the technologies in real-world applications.
The intended audience of this guide includes educators, school administrators, architects, design engineers, energy modelers, contractors, facility managers, and building operations staff.

The purpose of this handbook is to furnish guidance for planning and conducting a highperformance building charrette, sometimes called a "greening charrette." The handbook answers typical questions such as, "What is a charrette?", "Why conduct a charrette?", "What topics should we cover?", "Whom should we invite?" and "What happens after the charrette?". Owners, design team leaders, site planners, state energy office staff, and others who believe a charrette will benefit their projects will find the handbook helpful.
This paper introduces a classification system for net-zero energy buildings (ZEB) based on the renewable sources a building uses.
