Alter Concept luminaires can be equipped

We need to use our planning and design skills to help our society
move from a ‘throw-away’ mentality to one in which we limit energy
and resource use.The idea of building less is the essential concept of
green design. It resonates with all the big sustainable ideas: less land,
square footage, material, waste, toxicity, energy, water and cost.
