The movement for housing that is energy efficient and in harmony with the environment is gaining steam in the heart of Peru's capital with support from developers, investors, and lenders.

Builders are increasingly including features such as solar panels, water-recycling systems, and technology that minimizes the need for energy.

"I can't imagine making a building without these characteristics," Fernando Carrasco, general manager of Lima-based construction company Creativa tells Efe.

He says that the firm begins every project by asking, "how can we make people feel the structure helps them?"
