The document discusses the inefficiencies of using spreadsheets for energy management in buildings, highlighting issues such as manual data entry and time consumption. It emphasizes the need for intelligent energy management systems (IEMS) that automate utility bill management and centralize real-time energy data to identify and achieve energy savings. The primary goal is to improve operational performance and reduce maintenance costs through better energy monitoring and management.

1. Smart Guide to smarter
energy management

2. Buildings are full of hidden energy savings
potential that can be uncovered with
❖ right analysis
❖ right benchmarking of
energy usage
❖ right plan of energy
saving journey.

3. Would you be able to manage all these
tasks in high-end spreadsheet?
Answer is: “No”.

4. The truth about spreadsheet:
It is no longer viable or smart enough to have
teams spend their precious time manually
filling in data. Scanning each bill for their
biggest cost drivers, and hoping the graphs
make sense as they present findings to
executives and finance teams.

5. Problems with spreadsheet:
❖ Dependency on manual-effort
❖ Errors in manual data entry
❖ Manual meter readings
❖ Misaligned resources
❖ Time-consuming process
❖ Missed opportunities

6. And time is money – you
cannot afford to waste....
The biggest barrier to energy management
success is the ability to make a business
case for energy management tools and
technologies.

More tenant occupants arrives, few meetings in
conference rooms start in
More meetings in conference rooms go
in, many daily service providers arrive
Sun pours in through south facing
windows, tenant occupants moves around
cafeteria and lobbies, lawns
Tenant occupants return offices,
meeting in conference rooms go on
Most of the building is empty
Nobody is in the building

system adjusts airflow and temperature

9. And there is a saying,
“You can not track what
you don’t measure”.
There is a better way:
iEMS (Intelligent Energy
Management System) with
automated utility bill
management and real time
energy data centralization
