Hello. Thank you for posting your query at DoctorSpring.com
I have noted the details.
I agree that extreme temperatures could trigger seizures, especially heat. However, staying in a house without temperature regulation is unlikely to trigger seizures, as we do not expect extremes of temperature there.
Also, more important is to treat any fever she gets. This is because fever, if more then 100 degree F may trigger an episode of seizure in a child.
Further evaluation would require doing a brain scan, preferably an MRI and EEG (electroencephalography).
Since she has had two seizures, it is safer to start anti-epileptic drugs to prevent further seizures.
I hope it helps.
Best wishes,
