So far sa mga magazines and online photos nang houses lately, wala pa ako nakikita na nag-a-advertise for building ECO friendly houses. Which is sad, considering we're a tropical country, andaming pakinabang from sunlight. May mga builders ba na nag i-install ng solar panels there? Me and hubs are looking for a builder who knows how to be ecologically friendly like using collecting gray water,rainwater, etc? TIA sa replies!
