22. SUSTAINABLE BUILT DESIGN  Insulated windows  Insulation boards (WALLS)  Insulation boards (ROOF)  Water storage tank

23. Insulated Windows  Low-E windows  Reduce energy Cost 25% to 50%  Increase confort levels.  Eliminate hot and cold spots  Reduce noise up to 70%

24. Insulation Boards (WALLS)  Energy Saver  Insulates any part of the building  Good thermal resistance  Reduces heat conduction  R19

25. Insulation Roof Boards  Heat insulation, waterproof, fireproof  Less smoke and harmful gas  Chemical resistance  Wide temperature limit  R30

26. Water Storage Tank Advantages:  Independent water system  Gather water for recycling  Irrigation purposes
