The scope and intent of this document is to provide guidance to Owners, Operators, Designers, and Professional Service Providers on how to best implement Indoor Air Quality (IAQ) improvements, including risk mitigation strategies, in educational facilities. The guidelines will also help facilitate discussion between designers and stakeholders, identify minimum recommendations and discuss further considerations to improve IAQ and reduce the risk of transmission of infectious pathogens and other contaminants of concern.

Advanced Energy Design Guide for K-12 School Buildings
ATLANTA—Inefficient lighting, uncontrolled plug loads and poorly insulated roofs are just few of the factors that can contribute to a failing grade in energy consumption for K-12 school buildings. Fortunately, guidance is available to help design teams constructing K-12 school buildings cut annual energy use by 50 percent or more using off-the-shelf technology. Fortunately, guidance is available to help design teams constructing K-12 school buildings cut annual energy use by 50 percent or more using off-the-shelf technology.
To help ensure schools receive an A+ in energy efficiency; owners, engineers, designers, architects, and others on the building team are encouraged to download the free Advanced Energy Design Guide for K-12 School Buildings: Achieving 50% Energy Savings Toward a Net Zero Energy Building. The guide is the second to be released in a series which provides recommendations to achieve 50 percent energy savings when compared with the minimum code requirements of ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings.
The new guide features easy-to-follow recommendations for various climate zones and how to implement tips via a series of real-life school construction cases. Also included is information on integrated design, including best practices, as a necessary component to achieving 50% energy; and the inclusion of a performance path, specifically offering guidance for early stage energy modeling and annual energy use targets to help with goal setting.
Additional design tips include:
> High performance building envelope that is better than Standard 90.1-2004.
> Different ways to daylight 100 percent of the floor area of classrooms, resource rooms, cafeterias, gymnasiums and multi-purpose rooms for two thirds of the school hours.
> Methods to achieve space-by-space interior lighting densities that are, on average, 40 percent better than Standard 90.1-2004.
> Ways to reduced exterior (façade, walkway, parking lot and drive) lighting energy consumption.
> Recommendations for computers, vending machines, kitchen cooking equipment, walk-in refrigeration equipment, kitchen exhaust hoods and service water heating.
> Three different HVAC system types that achieve significant energy savings over a typical system.
> Recommendations for commissioning and measurement and verification to ensure that energy savings potentials are realized.
The AEDG also addresses the notion that energy efficient buildings are more expensive.
