"...Today the Energy Department launched the Better Buildings Zero Energy Schools Accelerator. Six school districts, two states and several national organizations are working collaboratively to develop zero energy design that is cost-competitive to conventional construction in the education sector and in local communities across the nation

"...today the U.S. Department of Energy (DOE) and the National League of Cities launched the Better Buildings Zero Energy Districts Accelerator to move the building market toward adopting sustainable practices to help districts achieve zero energy use in buildings. Zero Energy Districts are comprised of multi-purpose energy-efficient buildings, where the annual energy delivered to buildings is less than or equal to on-site renewable exported energy

"Consumers wanting to undertake a deep energy retrofit of a home currently face a challenging process that involves multiple complex steps, as shown in the infographic [shows barriers and opportunities] below. For this reason, many give up on energy efficiency

"DPR Construction’s retrofitted San Francisco headquarters building achieved approximately 20% net positive energy its first year of operation using efficient systems including HVAC, electrical and PV. And, in late 2015, it was certified as a net zero energy building. The office building demonstrates the capabilities of integrated, innovative, and replicable design. And, it proves that sustainable buildings can reduce energy use and improve indoor environmental conditions, while being cost effective. It has become a hub for learning and collaborating on many sustainably minded design projects.

"The 2015 International Green Construction Code (IgCC) includes many progressive measures that will improve the energy performance of buildings. One important provision describes the Zero Energy Performance Index (zEPI), which provides a scale for measuring commercial building energy performance. zEPI represents a fundamental shift in measurement of building efficiency as it sets energy targets for actual energy consumption rather than using a predictive energy model of building energy performance to calculate a “percent better than code” metric. zEPI sets an energy use intensity (EUI) target for building type and is adjusted for climate. It is also the measure by which a building’s energy efficiency is calculated once operational and occupied based on measured energy use data

"Buildings account for nearly 40 percent of U.S. carbon emissions (PDF). This means that low emission buildings must be part of our clean sustainable future. Initiatives such as Architecture 2030 and California’s Title 24 are not only helping to pave the way by creating a general framework for sustainable buildings but also pushing the boundary with Net Zero Buildings (NZBs) or Zero Energy Buildings (ZEBs) that aim to almost completely offset a building’s adverse climate change impacts. These buildings will produce just as much energy as they consume and will be commonplace by 2020 and 2030.

"This month, our State of Technology series focuses on energy codes. Let’s talk about two innovations in development over the last decade in energy codes: outcome-based energy codes and zEPI [Zero Energy Performance Index]. Both started as dreams of energy code wonks to address the problems with existing code and benchmarking solutions, and both have been gaining prominence and momentum in the energy codes world

"With the National Parks Service’s 100th anniversary in 2016, humility and recognition of stewardship were of primary importance when leaders at Bryce Canyon National Park in Utah decided they wanted to take their Visitors Center and main operational offices to zero net energy (ZNE) before the 2016 Centennial celebrations. With over 1.5 million visitors to the park every year, they wanted a solar power solution designed to educate, inspire and above all, be the gold standard for ecologically responsible solar
