Owner house is facing the sea, and is getting sun throughout the whole day. Windows are closed and the air conditioning is on 24/7. This resulted in high electricity bills of $1000 per month, and owner still has to suffer the heat in the house. There was also existing films but it was not good enough.
We installed Green40 and Green15 for the whole house and the effect was immediate. The house is much cooler and electricity bills even dropped by 40% to $600 per month.
