I made model using eQuest 3.65 and after simulation, baseline
building generation and results compliance I see 55 % percent
improvement in proposed design against the baseline design.<br>
This model is just schematic for CS precertification but the
envelope is modeled with most probably final design that will be
built. The envelope is kind of a modular system with overall U
factor 0,14<span class="Apple-converted-space"> </span><a

both glass a wall parts).<br>
<br>
My question - is it possible to get 55 % improvement against the
baseline with this U factor? I checked, that LEED requirements is
Umax 0,513, so our value is very good compared to this
requirements. However compared to our local norms (Czech republic)
it is not anything extra, so the 55 % percent improvement
surprised me.<br>
In HVAC system I used everywhere standard efficiencies of motorts,
pumps etc. and VSD regulation, but this I think doesn´t have as
large impact on the result as the envelope - or does it have?<br>
<br>
Thanks a lot for all thoughs and answers.<br>
