requirements may be helpful in moving this discussion forward. Per LEED
EAc1 requirements:<BR><BR>"<I><SPAN style="FONT-STYLE: italic">The default
process energy cost (must) be 25% of the total energy cost for the Baseline
building. For buildings where the process energy cost is less than 25%
of the baseline building energy cost, the LEED submittal must include
supporting documentation substantiating that process energy inputs are
appropriate. </SPAN></I>"<BR>...<BR>"<I><SPAN style="FONT-STYLE: italic">For
EA Credit 1, process loads shall be identical for both the Baseline building
performance rating and for the Proposed building performance rating.
However, project teams may follow the Exceptional Calculation Method (ASHRAE
90.1-2004 G2.5) to document measures that reduce process loads.
Documentation of process load energy savings shall include a list of the
assumptions made for both the base and proposed design, and theoretical or
empirical information supporting these assumptions.
</SPAN></I>"<BR><BR>Buildings with 60% process energy cost probably will
likely be negatively impacted by these modeling requirements (it is probable
that these buildings will have a tougher time showing substantial Percentage
Energy Improvement than buildings having only 25% process loads).
However, if the project can demonstrate that energy improvements have been
made to the process energy systems versus standard practice, then the energy
savings achieved through these process system efficiency measures can be used
to document improved Percentage Improvement using the Exceptional Calculation
Methodology. As Leonard mentioned, the process energy will also impact
cooling loads substantially, and improvements to the cooling equipment and
controls would also help the overall building performance. <BR><BR>Gail

<P><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt">What has
the <FONT color=black><SPAN style="COLOR: black">process energy
cost</SPAN></FONT> (or the process energy use) got to do with building
design related to energy efficiency (architecture-envelope, lighting,
HVAC, DHW) except power supply for the process? The process energy
within an office building can vary from 0.5 w/sf (minimal
use of computers and office equipment) to more than 6.0 w/sf for a
financial/trading (Wall Street) type of building. If the baseline
process energy is limited to 25% percent of total and the proposed process
energy use is more than 60% of the total then does this mean that the building
design is energy inefficient and does not qualify for LEED
certification?<o:p></o:p></SPAN></FONT></P>
<P><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt">Process
energy could be part of the analysis if there is a baseline standard for
various types of computer and office equipment (varies considerably and hard
to define and prescribe for the numerous types processes that occur in just
office buildings) and the equivalent proposed equipment is more
efficient. This comes under "Exceptional Calculation Method" category
along with several other energy efficient building design options such as
double-wall buildings for which you get 1 point (I
think).<o:p></o:p></SPAN></FONT></P>
<P><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt">According
to LEED-NC Version 2.2 EA Credit 1 page 174 "process energy is considered to
include, but is not limited to, office & general miscellaneous
equipment, computers, elevators & escalators, kitchen cooking &
refrigeration, laundry washing & drying, lighting exempt from lighting
power allowance (e.g. lighting integral to medical equipment) and other (e.g.
waterfall pumps). Do all submissions for LEED certification include all
this. At the construction documents submission stage, what is the level
of modeling detail that is required regarding floor spaces and zones and all
the systems, plant and equipment shown on the drawings and
specifications. Can you use eQUEST, select the type of building,
and let the "Wizard" do the zoning and assume most of the baseline
data? I don't think we are all playing the same game, on the
same level playing field and using the same rules to show percent energy
savings for LEED certification.<o:p></o:p></SPAN></FONT></P>
<P><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt">I also
have some reservations about how various energy saving systems are modeled
with different computer programs. The programs should be studied
and compared with the same case studies of different types of buildings with
different systems and plants and showing how each program should be
used to demonstrate energy savings from different energy conservation measures
such as UFAD. <o:p></o:p></SPAN></FONT></P>
<P><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt">Building
operation data can now be viewed on the web, collected for meaurement &
verification (M&V) and can be used to check computer modeling
results. In the case of a M&V project at IIT, the web based control
systems show mainly temperatures. Sub-meters and data loggers should be
included in the control specifications so that the performance of the major
systems, plant & equipment can be monitored separately and compared with
computer results. At the moment we are comparing the building utility
meter reading with the bottom line building energy use calculated by the
computer program. <o:p></o:p></SPAN></FONT></P>

they summarize how, by consistently implementing power management on
computer monitors and CPUs using a simple utility program, a cost

173 "must comply with the mandatory provisions (Sections --- ) in Standard
90.1-2004 (without amendments)" There is no mention of Standards 62
for ventilation & occupancy density or Standard 55 for indoor
comfort conditions. Does this mean that the baseline can be based on
the proposed ventilation, occupancy density and indoor comfort
conditions? According to Standard 62-2004 the occupancy density for
general office space is 200 sf/P (from 142 sf/P in 62-2001 and I think 100
sf/P earlier). This produces a low percent system outdoor air and
energy conservation measures such as "occupancy based ventilation" and
"outdoor air to relief air heat recovery" have little effect. Std
62-2004 (also Std 90.1-2004 for lighting) provides design criteria for a
limited number of space types such as a prison cell (improved from 50 sf/P
& 20 cfm/P in 62-2001 to 40 sf/P & 10 cfm/P in 62-2004) .
This makes it difficult to determine baselin e conditions using Std
62.<o:p></o:p></SPAN></FONT></P>

merits for the 2.1 method and the 2.2 method. On the one hand,
the process loads are to some degree out of our control. But on
the other hand, if you have a building with such massive load density why
would the rating system want to exclude all of that energy from sustainable
practices?</SPAN></FONT><o:p></o:p></P>

<P class=MsoNormal><FONT face=Arial color=blue size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: Arial">I like the idea of
consistency when considering all of the energy for energy optimization,
on-site renewables and green power - there are projects out there
that might earn fewer EAC1 points under v2.2 than under 2.1. The
percentage savings were changed between the versions so it's hard to say if
it is more or less likely to earn a certain amount of EAC1 points
- I would be interested to see a summary if the data is available about
EAC1 points under v2.1 compared to v2.2. Probably about the
same?</SPAN></FONT><o:p></o:p></P></DIV>

<P class=MsoNormal><FONT face=Arial color=blue size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: Arial">For a high load
density building like yours - definitely going to be harder. The only
suggestion as far as EAC1 points that I could offer would that if your
design has receptacle load at 6 W/ft2 there is probably a significant
diversity in that load, maybe it won't turn out as badly as you
fear.</SPAN></FONT><o:p></o:p></P></DIV>

<P class=MsoNormal><FONT face=Arial color=blue size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: Arial">In regard to
ventilation, you are going to use the outside air requirements from the
proposed design and apply that outside air quantity to both
models. There isn't a "baseline ventilation rate" -
use equal CFM of OA for both models. Also, OA may be determined
from local building codes rather than ASHRAE - that would also apply equally
to both models.</SPAN></FONT><o:p></o:p></P></DIV>

style="FONT-SIZE: 10pt; COLOR: blue; FONT-FAMILY: Arial">The one exception
would be that Demand Control Ventilation could potentially be used in the
proposed model to reduce OA if DCV isn't required prescriptively, and if
your minimum OA from code is less than what is required by ASHRAE
62.</SPAN></FONT><o:p></o:p></P></DIV>
