Hi all,
I have a couple of questions to ask, I am new to the IES software and as a student I have to write a report in experimental data.
1) why does changing fuel type not change peak heating and cooling load along with plant sens load at all
2) why does making the glazing on the south side larger mean the peak boiler and chiller loads are greater? Shouldn't it improve the design and make it more economical ?
Question on Peak heating and cooling load

Re: Question on Peak heating and cooling load
Hi midolia,
to answer your questions:
1. Fuel type will just change the source of energy for your system, it bears no effect on your building's load. The load is calculated from the internal and external gains on your building.
2. Excessive glazing on the south facade is actually a bad design. The sun is actually south oriented (if you in the north hemisphere) rising and setting east to west respectively. The more economic option would be glazing the northern facade to provide sufficient daylight while minimizing and shading the glazing on the southern facade.
Hope this helps.
