  • Conclusion Anticipated Benefits of Sustainable Features and Possible Implementation Problems
  • Concluding Statements Anticipated Benefits of Sustainable Features  Reduced health problems such as allergic reactions, asthma attacks, headaches etc. (cleaner air)  Reduced electrical bills  Reduced water bills  Improved safety against fires  Lowered maintenance costs of structural and architectural elements (such as floors)  Lowered Carbon – footprint of the building (Low Global Warming Impact)  Increased social contact (Vegetated roofs can serve as community parks)  Conservation of non renewable energy sources  Conservation of landfill space Possible Implementation Problems  One technology may undermine the function of another e.g. use of certain ceramic tiles clashes with the function of the use of low VOC paints  Unanticipated costs related to implementation e.g. installation of geothermal heating system may cost a lot more than the estimated cost  Use of incompetent personnel for implementation may reduce impact of the features.  Requirement of separate personnel for implementation of each feature may arise
