to the heritage sites, which are currently being

                                    applied  on  commercial  properties.  Concisely,


                                    the  amount  of  research  focus  on  such

                                    approaches is very limited. Heritage buildings


                                    considered  as  an  indispensable  component  of

                                    the environment. The key agents contributing


                                    to its deterioration are solar radiations, winds,

                                    moisture that result in the physical weathering


                                    of  the  site.  Therefore,  it  is  now  well

                                    established that the heritage value quotient at


                                    the  built  sites  is  being  reduced  due  to  the

                                    environmental  factors  viz.,  societal  (a.k.a.

                                    socio-cultural/community),  economic  (a.k.a.


                                    financial/ monetary) and environmental (a.k.a.

                                    ecological).
