Most of the bigger buildings are fitted with Building Management Systems in commercial and residential establishments. Almost 60-70% of building utility bills are consumed by HVAC systems where HVAC systems play a pivotal role in overall building control systems being the major consumer for electricity usage.
Beyond lighting Retrofit, and water consumption optimization there are many areas like wastewater treatment, Security systems, Fire systems, lifts, hot and cold water, and pumps that consume 30-40% of utility bills where water takes the maximum load. An appropriate BMS system provides some of the above controls with a certain degree of limitations.
Practically, Smart, wifi, and wireless controls qualify better for HVAC, and pump management, lights are cost-effective and carry definite value propositions in an endeavor to provide smart building controls for energy saving. HVAC systems, smart switches along with other IoT devices, and a controller connected with a wireless BMS-type application having centralized two-way control make building smart where implementation of such a system can be done in weeks instead of months.
In a built environment where changes and modifications are not easy to come, retrofits with mechanical, and civil work modifications are costly, cumbersome, and time-consuming. With just having smart controls for HVAC, lights, and pumps building owners may have smart building controls in place for the optimum working of the building with smart saving.
