This document discusses strategies for managing energy across multiple buildings. It recommends taking a strategic approach by setting clear goals, assigning responsibilities, and allocating resources. Key aspects of an effective strategy include developing an organizational structure, conducting energy monitoring and analysis, establishing baselines, and identifying and implementing energy savings projects. Regular reporting of energy use, greenhouse gas emissions reductions, and cost savings is also important for maintaining momentum. Engaging stakeholders through communications, training, and energy champions can help achieve operational efficiencies. Structuring the program to focus first on awareness, operations, and the highest energy users and influencers can help realize early savings.

8. Energy Monitoring & Reporting
• A structured, multi-year approach is essential (M&V Plan)
• Energy savings cannot be directly measured
• Establish a baseline year
• € savings = gas saved 2011 x gas AUP 2011
• Sophisticated approaches available, if required
• Keeping it simple:
– Use same system for energy management and DECs
– Annual data is essential, monthly data is valuable
– Elec – online access – save data OR manual meter readings
– Gas – manual meter readings
– Oil/LPG – bills and tank opening/closing volumes
– Meter point number, readings & date should be saved!

11. Raising Awareness
• Identify key groups, their impact, allocate
resources accordingly
• Decide what you want them to do
• Find a proportionate means to secure buy-in and
communicate the message
• Develop a logo, turn it into a brand
• Use a website as your awareness hub
• Get a list of communications media / options
• Make a plan...

12. Group Impact What we want Method
Design & refurb Very high Efficiency and metering integral part Direct / organisational,
of design CPD
BMS Very high Scheduling, setpoints, control Direct / organisational
strategies
Maintenance High Efficiency to be on a par with comfort Direct / contract
management, CPD
Security High am - Leave lights off Contract management
pm - Switch lights off, close windows
Feedback
Cleaning Medium Switch lights off Contract management
IT/IS Medium Specific projects – build settings, Direct communication /

14. Lessons Learned for Multisite
• Goal is essential
– Specific, measurable, achievable
– Public commitment
• Strategy & structure should reflect goal
– 5-15% can be achieved from awareness & operation
– For higher level of savings need capital programme
– Awareness and operational based savings require
ongoing management
– Smarter controls and new installation require less
ongoing management, but have a capital cost

15. Lessons learned from multi-site
• Targeted Approach - Pareto principal
– Identify the 20% of buildings that consume 80% of use
– Identify the 20% of people that influence 80% of use
• Structure
– Leverage your own organisation – energy champions
– Use established groups and systems
– Engage with information services and secure
commitment

16. One last thing...
...start with a clearly defined goal,
policy and strategic plan.
