IIHS Energy Saving Initiatives

While data collection and monitoring of energy systems for buildings have long been used to improve performance, a recent influx of smart devices and sensors allow greater insights. Furthermore, a better reporting mechanism such as improved visualisation of end-use consumption, helps to understand the impacts of energy consumption trends and allows for a control lever that could be potentially used to manage ‘hot spots’. The IIHS BCC energy load is monitored based on end-use consumption as shown above.

While most contemporary efficiency measures focus on retrofitting the built fabric, continuous data analysis (with assimilation of new changes and updates) allows for better energy management at much lower marginal costs. For example, analysis along the temporal dimension helps identify key areas of peak energy usage including data on how much energy is being used at particular times of the day, which days of the week, and which particular equipment is responsible for it.

Targets

The energy monitoring system was set up in 2015 with the specific goal of reducing energy consumption in the building. Since then, the building management team has achieved a 30% reduction in total energy consumption. This was enabled by technological changes such as shifting to more efficient server precision AC systems and LED lighting systems, as well as behavioural changes brought out by raising awareness on the energy saving measures being adopted. Above is comparison chart of end-use energy load between 2017 & 2018 for the month of August. There has been a 10% reduction in total energy demand despite an increase in occupancy rate and number of events held.
