Completely true, many old homes in Madrid are freezing in the winter. New homes are more regulated in efficiency, however. I lived in a new A-rated flat with sophisticated central heating and thermosolar, paying 500€/mo for the actual home and about 10€/mo for heating.

Adding to this, I spent a week in a A-rated house. 30+ C outside and I never even looked for the remote of the air conditioner.
