Maximise your energy.
The energy efficiency scale is everywhere in our homes: on the fridge, on the washing machine, on the electricity bill. But it rarely stands for anything beyond technical numbers. So here's the idea: turn the "A+" rating into a pun. In Portuguese, "A+" sounds exactly like "há mais", meaning "there's more". So "Em tua casa A+ para ti" reads two ways at once: your home can be A+ rated, and there's more in it for you. Better energy efficiency, and a better place to live in.
