Over the course of 5 years, NREL worked with commercial building owners and their design teams in the DOE Commercial Building Partnerships (CBP) to cut energy consumption by 50% in new construction (versus code) and by 30% in existing building pilot projects (versus code or pre-retrofit operational energy use depending on the preference of the Partner) using strategies that could be replicated across their building portfolios. A number of different building types were addressed, including supermarket, retail merchandise, combination big box (general merchandise and food sales), high rise office space, and warehouse. The projects began in pre-design and included a year of measurement data to evaluate performance against design expectations. Focused attention was required throughout the entire process to achieve a design with the potential to hit the energy performance target and to operate the resulting building to reach this potential. This paper will report quantitative results and cover both the technical and the human sides of CBP, including the elements that were required to succeed and where stumbling blocks were encountered. It will also address the impact of energy performance goals and intensive energy modeling on the design process innovations and best practices.
"Zero Net Energy (ZNE) is the future, and in a growing number of places the present, of building design and energy policy. A growing strategy to get to ZNE is to separate the building’s heating/cooling from the ventilation/dehumidification. Design firms and owners are striving to meet heating, ventilation and air-conditioning (HVAC) loads with optimum comfort and minimal energy. Radiant systems can provide heating and cooling through pipes while ventilation and any humidity control requirements are efficiently met by a Dedicated Outdoor Air System (DOAS). This guide provides an overview of Radiant Heating and Cooling + DOAS systems."
"One of the fastest growing trends in school design is Net Zero Energy Schools. There are now [in 2011 when the article was published] at least a dozen or more schools completed or in construction that have achieved, or have committed to, this incredible level of energy efficiency. In this article we’ll examine this trend and take a brief look at some of the exemplary projects that attempt it."
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.
This study expands and validates previous research by Heschong Mahone Group that found a statistical correlation between the amount of daylight in elementary school classrooms and student performance. The researchers reanalyzed student performance data from two school districts to answer questions raised by the previous study. The results are consistent with the original findings and affirm that daylight has a positive and highly significant association with improved student performance.
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."
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."
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.
