Introduction
To create and recreate the world’s building stock in a manner that sustains the well being of humanity
requires planning, concerted effort, and bold action. Formed from our imagination, a single vision must be
shared by all who design, build, and operate the structures that house life on our planet and that foster the
productivity that defines our civilizations.
This report describes the vision held by members of the American Society of Heating, Refrigerating and
Air-Conditioning Engineers. This vision is of a future when buildings will produce as much energy as they
use. These are net zero energy buildings (NZEBs). We believe such buildings can be market-viable by the
year 2030.
Our vision can be realized only if ASHRAE,working within the framework of the building community,
provides to its members by 2020 the tools necessary to design, construct, and operate NZEBs. To achieve this
critical milestone, now is the time to plan strategically and to act decisively.
NZEB Technology
Buildings consume 40% of the primary energy and 71% of the electrical
energy in the US.Driven by economic expansion and population growth
that require more and more facility space each year, energy use in the US
commercial sector is expected to grow by 1.6% per year. This is resulting in
an energy impact that is increasing faster than all of the energy conservation
measures being taken and retrofits being made to buildings.
ASHRAE’s vision, as articulated in this report, is that the building community will produce market- viable net
zero energy buildings (NZEBs) by the year 2030.
The concept of NZEBs includes only the energy flows of the building, not the overall sustainability of the
building. It is a critical step toward achieving the objectives of building sustainability as articulated in
ASHRAE’s Sustainability Roadmap. The quality of the indoor environment must not be sacrificed in the pursuit
of NZEBs. And while new buildings are the focus of ASHRAE’s NZEB vision, existing buildings must be
addressed as NZEB strategies are implemented.
