• Reuse of the existing building façade
• Natural, low toxicity, breathable materials
• Bio-climatic design enhancing cross-ventilation and eliminating the need for cooling systems
• Energy efficiency through carefully studied window positioning, shading devices, and natural eco-friendly thermal insulation
• LED lighting and zoning of lighting
• Solar water heating panels for domestic water
• Wood pellet stoves for space heating
• Rainwater harvesting for irrigation and toilet flushing
• Low water fixtures and low energy appliances
• Vegetated green roof and garden with native plants
• Photovoltaics for electricity generation currently under way
