The results of the ASHRAE project I finished are described below.
The final report package includes lots of EnergyPlus IDF files
implementing the 30 measures examined as well as the scripts used to
generate them with Eppy.<br>

style="font-size:14px">The question of how energy
efficient can commercial and multifamily buildings become
in the near future if first cost is not considered was
explored in ASHRAE 1651-Research Project, Development of
Maximum Technically Achievable Energy Targets for

<p> <span id="VOCUSHTML"
style="font-family:arial,helvetica,sans-serif;font-size:10pt;"><span
style="font-family:arial,sans-serif"><span
style="font-size:14px">The value of establishing such
ultra-low-energy targets for buildings is two-fold, Jason
Glazer, principal engineer for GARD Analytics who oversaw
the project, said. These targets will indicate to
building design professionals what may be achieved if
first cost is not considered and challenge the creativity
of those professionals to achieve similar results in
actual designs with the real-world constraints of first
costs. They also will help advance design guides,
standards and codes by providing an ultimate goal.</span></span></span></p>

style="font-size:14px">For the project, researchers
assembled a list of energy efficiency measures that can be
included in the design of non-residential buildings. The
list included both commonly used and cutting edge energy
efficiency measures, according to Glazer.</span></span></span></p>
<p> <span id="VOCUSHTML"
style="font-family:arial,helvetica,sans-serif;font-size:10pt;"><span
style="font-family:arial,sans-serif"><span
style="font-size:14px">From the resulting list of almost
400 measures, 30 were chosen for additional analysis.
Sixteen prototype buildings that were consistent with
Standard 90.1-2013, <em>Energy Efficiency Standard for
Buildings Except Low-Rise Residential</em>, across 17
climate zones were used as baseline models. The 30
measures then were individually modeled. Each of the 30
measures, often with many options, were applied to each
building and climate combination. In general, the measures
were applied in the following order:</span></span></span></p>

style="font-size:14px">It is useful to understand how far
energy efficiency measures can go to reduce the use of
energy in the built environment, Glazer said. It is also
important to understand that many of the measures used in
the project are widely available today.</span></span></span></p>

each of the 272 building and climate combinations, if the
energy consumption was reduced, it remained in the model.

nearly cut in half compared to Standard 90.1-2013.</span></span></span></p>
