38. 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
