How to determine the amount of continuous insulation required by codes, while still retarding water vapor according to climate zone locations

"While ASHRAE 90.1 has been pushing continuous insulation (CI) for the past decade, the building codes are catching on. And now that the U.S. Department of Energy (DoE) has mandated all states to adopt a commercial building energy code that meets or exceeds ASHRAE Standard 90.1-2010, CI specifications are really being cast into the spotlight."
In the cold climate of the upper Midwest, air-source VRF systems have difficulty meeting heating loads when the outdoor temperatures drop below -5ºF. Because of this difficulty during common cold spells, they are either oversized (adding to system cost) or supplemental heat is added (adding to operating cost). Cold temperatures can also cause frost issues around outdoor units, as well as compressor failure. A VRF system served by a water loop—in place of air—does not have these issues, making the technology more practical and effective in cold climates such as the upper Midwest. A water-source VRF system can be connected to a boiler and cooling tower or, for even higher performance, a ground heat exchanger.
A report with case studies on 15 Zero Energy schools in the U.S., prepared to help Baltimore City Schools in its building planning.
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."
Presentation at CxEnergy 2014 conference by Hanson, Inc. the commissioning agent for Sandy Grove Middle School. Sandy Grove, in Lumber Bridge, NC, is the first Zero Energy school built with a public-private partnership in the U.S.. Presentation includes technologies used, benefits of Zero Energy, common issues with the technologies they used, and lessons learned.
7x7x7: Design Energy Water is an innovative program by the Division of the State Architect that encouraged California school districts to develop long-range master plans that reduce energy and water consumption on campuses and improve the quality of educational spaces. The State Architect engages seven architectural firms to develop seven conceptual case studies that reduce school energy and water consumption and result in better learning environments on seven different types of campuses (six K-12 schools and a community college). The seven campuses are representative of typical building types from different eras constructed across California’s varied climate zones. The purpose and primary goal of this program is to enable all existing K-14 facilities to be zero energy by 2030.
This case study describes a successful zero energy school project in Utah.
This case study details the successful achievement of Passive House performance and zero energy at the Friends School of Portland.
The Energy Lab at Hawai’i Preparatory Academy is the third building worldwide and the first K–12 school facility to achieve “Living” certification through the Living Building Challenge (LBC). This case study details how the project succeeded in these goals.
