[esp-r] Re: Effect of adjacent building

[Achim Geissler]

Dear Minhwan

 

is only the control >file< for the three separate buildings the same? You
have defined three separate control sets, one for each building?

 

Did you write out the QS with everything set to “verbose”? Experience
says that copying zones / buildings may lead to inconsistencies even though
no messages are given. I would go through the verbose QS report with a very
fine comb …

Subject: [esp-r] Effect of adjacent building

 

Hi everyone

 

I am comparing energy performance of 3 glazing.

 

At first I made up 1 building and copied 2 other buildings from it.

Copied building has their own tmc and con files and they share opr and ctl
files with original one.

Height of building is 7.8 m and distance between buildings is 10m.

But when same glazing is applied to all 3 buildings, the result was
interesting.

Compared to original building, 2 copied buildings occurred 16 % more
heating load, though there is no obstruction.

But 2 copied one shows very similar pattern and load.

When I look at room temperature, the original one has 0.5~2 degree higher
temperature than copied one.

copied one shows exactly same pattern. I guess adjacent buildings affected
the amount of solar penetration.

 

As a second try, I placed copied building at 30m distance from original one.

But the result was same. it occurred 16% more heating load than original
one, and same temperature profile.

 

Does adjacent buildings affect the other, though I didn't make and activate
obstructions?

If not, should 2 building which are close to each with same condition show
same result?

In my case, do you have a comment on what I should look to figure out what
the reason is?

 

Thank you in advance.

 

Regards

 

Minhwan
