Do you dataset where I can I at least retrieve construction costs
per building components? Such as a breakdown of Envelope/Energy
Plant Facilities/Plumbing/Elevators etc..?<br>

<p class="MsoNormal">Hi All,<br>
<br>
thank you all for your quick response. Actually I don't want
to calculate that value, but just need to cite/reference a
source that gives information about this data. <br>
<br>
I found this <a moz-do-not-send="true"
href="http://www.sustainablefacility.com/articles/print/86593">http://www.sustainablefacility.com/articles/print/86593</a>
where a graph is shown...but not really references fully. It
says about ASHRAE Std 90 - I dont have access to this. Is this
a chart inside the Do you know if it is inside the ASHRAE
standards? <br>
<br>
In particular I'm looking at expenditure through external
vertical walls/windows - hence facades especially in office
buildings.<br>

what you are looking for, but we have a video tutorial
showing an envelope elimination parametric. In this example
we used a full service restaurant but you can do this with
any model. The approach is to run a baseline simulation and
then to switch all exterior and ground exposed surfaces to
an adiabatic boundary condition. Next remove all
fenestration surfaces. Then re-run the model. Due to the
load driven nature of this project the maximum savings
through envelope improvements was just over 3%, but maybe
would be 15-20% for an office. Of course it depends where
the project is located; the harsher the climate, the more
potential savings through envelope improvements. And it
depends on the quality of the envelope that you use as a
starting point; building activity, and mechanical system
efficiency. </span><o:p></o:p></p>

Hi All,<br>
<br>
Can anyone advise a good resource (article, webpage,
book, etc..) which states what is the average energy
demands (construction+running costs) due to Envelopes
only in buildings? I would need just a figure in
percentage over the whole energy demands of a typical
office building. Is this data somehow available?<br>
<br>
