Solar panels vs. energy management

A solar pv system is a great way to reduce your grid energy consumption however optimising your energy management often provides access to lower hanging ‘fruit’. Below is the energy consumption profile of a two story corporate office. The weekday and weekend daily energy consumption is very similar, which is indicative of the building management system not recognising ‘weekend’ days and appropriately adjusting HVAC and lighting systems. A simple reprogramming of the BMS would yield significant energy, cost and environmental savings at no cost. I love data!
