From connecting your existing data to helping your team take action, here’s what you need to know about Emma AI.
Explore all FAQs →How does Emma AI find energy waste?
Emma AI analyses your utility data to learn how each site uses energy and spot unusual consumption patterns. It identifies potential causes and sends practical advice to help your team investigate and reduce waste.
We already have an energy management system. Can Emma AI help?
Yes. Emma AI can complement your existing system and energy management team by automating routine analysis. It sends site-specific advice directly to the people who can take action, helping turn meter data into practical improvements.
Do we need new meters or equipment?
Often, Emma AI can use data from your existing meters, without new equipment. This depends on the data available and how it can be accessed. Where more detail is needed, we can advise on connecting existing sub-meters or adding metering.
How much work will our team need to do?
Emma AI handles the ongoing analysis and provides clear recommendations, reducing the time your team spends searching through data. Your staff investigate and act on the advice, while their feedback helps Emma AI understand your operation.
Can it work across different buildings and sites?
Yes. Emma AI learns the consumption patterns of each site individually, recognising that buildings operate differently. The level of detail available depends on your metering, with building-level and sub-meter data helping narrow down where waste occurs.
How much does Emma AI cost?
Contact us for a quote for your estate and monitoring requirements. We can discuss the data you already have, the coverage you need and whether any additional metering is required.
Sub-metering services
See where your energy really goes
Go beyond your main utility meter. Sub-metering shows how much energy individual buildings, departments and equipment use, helping you pinpoint waste and prioritise improvements.
We install and connect meters to give Emma AI a clearer picture of your consumption — backed by ongoing maintenance and support.
Connected energy data
Bring your energy data together
Your meters, building management systems, solar panels and EV chargers can hold valuable information about how your estate operates.
Emma AI brings compatible data sources together to help you spot energy waste, investigate unusual consumption and understand performance across your sites.
