[Bldg-sim] Insulate the roof in summer without HVAC system yes or no?

[Julia Chabrera]

David,

I must admitt that it´s really extrange what it's happening to you. But the
only explanation is the SRI that it may change when you change the roof
composition. A metal sheet can easy have a SRI 0.6 and cement unpainted 0.2.

In a way it´s true that when you have a building with high internal load
and no HVAC system when you increased the insulation level in the envelope
the interior temperature normally gets high. (In the same way that
insulation dont let external heat get in, it doesnt allow internal heat
gets out). But in this cases it´s always recomended to keep the roof
insolation high.

Good luck!
