After passing stages of architecture , design , running and construction of any building , maintenance and repairs when exploiting is main pillar to secure comfort and welfare condition of building residents .

Installations of cooling , warming and air conditioning with 70 % of portion of energy consumption of a building are known as outstanding consumer of this part and as heart and lungs of a building , they are always exposed to maximum costs of repairs . Actively and preventively maintaining and repairing cause a suitable , continuous and sustainable function of installations to keep health and productivity of building residents .

In view of working nature , installations of a building are always working to continuously secure internal air condition and hygienic warm water and this performance causes gradually eroding devices and finally , reducing efficiency of installations , increasing costs and suitable inefficiency .

A main cause of this subject refers to mainly-reactive and based-repairs (and not correct and preventive maintenance ) approach in Iran .

To solve this intelligence-making problem , online monitoring and metering of water and energy in frame of using “integrated software of energy management in building” are efficient tool for intelligent maintenance and by following it, instantaneous supervision and control on performance of equipments to secure quality of exploitation of building installations that causes to increase satisfaction level of owners and residents .

Improving and developing business space of maintenance and repairs contractor companies by using capacities of energy services companies and knowledge-based companies
Recent developments in area of technology and object internet have been admitted to building uses and especially , HVAC installations .

Valuable experiences have been gotten in recent years in this area , so that at present, Heating , Ventilation and Air Conditioning installations and information analysis made of this operation have use in different parts that has been explained in the following diagram as summarized :

In this end and by using above capacities, possibility of synergy has been provided between installations internet companies, knowledge-based companies ( producing hardware and software products) and ESCO ( energy services) companies to develop and improve business space in this area .
