The American National Standards Institute (ANSI) Energy Efficiency Standardization Coordination Collaborative (EESCC) has developed the Standardization Roadmap: Energy Efficiency in the Built Environment.

The roadmap details 125 actionable recommendations to advance energy efficiency in the built environment.

The US Department of Energy estimates that the country’s buildings account for over 70% of total electricity use in America and 40% of the nation’s total energy bill, at a cost of $400bn a year.

ANSI said with 20% or more of the energy wasted, comparable reductions in energy have the potential to save an estimated $80bn per year.

The roadmap identifies timelines for action across five inter-related areas of focus that include building energy and water assessment and performance standards, system integration and systems communications, building energy rating, labeling, and simulation, evaluation, measurement, and verification and workforce credentialing.

ANSI president and CEO S. Joe Bhatia said energy efficiency is a complex, cross-cutting issue that applies to all industry sectors, impacts various government agencies, and hits every stage in the life cycle of a building.

"The release of the energy efficiency standardization roadmap marks an important step forward in advancing a coordinated national approach to energy efficiency standardization, and the recommendations outlined in the roadmap are both actionable and achievable," Bhatia added.

"Working together to pursue the EESCC’s recommendations, we stand to make great gains for the energy efficiency market and the nation."
