This is the answer to the question What is an alternative to blinds on large windows to protect your home from overheating in the summer?
Revision 1
Actually, you should thank your energy consultant. The summer thermal protection is often swept under the table and here there are often questions about what you can still retrofit with the problem.
If the sun's rays should stay outside, the only options are small windows, exterior shading (much more efficient than interior shading) or a large roof overhang that must fit the house. I personally find external venetian blinds the best option here. On the one. On the one hand you have the shading and on the other hand still the transparency to the outside. With shutters you have just on or off or light or dark.
