Work Group Leader of Pilots:

The objective is
to facilitate and stimulate the co-creation of the pilot design and planning, adopting and creating good practices (WP6)
to test and evaluate the five different implementations (WP7)
To share, discuss and co-create common elements at each pilot
To involve the end users and citizens (Living Lab Methodology) into the process
To exchange of experiences and the co-creation of new ones aiming to identify common elements in S.E. 5 pilots
Work Group is more horizontal than Workpackages and it should facilitate and complement the work and coordination of Workpackages
Only temporarily, during the time it is required

Measuring the energy savings

In SAVE ENERGY we are aiming into changing two things during the project:
Changing the user behavior to save the energy
Decreasing the energy consumption
How to measure these changes?

we need to know what to measure
 what are the indicators (Task 1.2 Save Energy Concept, Task 3.3 Performace indicators…?)
How to measure the pilot buildings’ energy performance
Energy audits (Task 2.3 Energy audit methodologies and procedures)
The measure of the user behaviour
 How to measure this?

Energy indicators
General indicators:
Heat consumption kWh/rm3
Electricity consumption kWh/rm3
Water consumption m3/rm3
Water consumption l/m2
Primary energy consumption kWh/m2
CO2 consumption kg/m2
Water consumption l/m2
Carbon footprint kg CO2
Taylormade indicators for each pilot ?
Kitchen energy and water consumption kWh/portion, l/portion
Energy consumption of lighting kWh/m2, kWh/user
Heat consumption in gym etc. kWh/m3, kWh/person

Energy audit vs. energy certificate

Energy audit is an overall analysis of building’s energy consumption including the real measurement data from the building.
The result of an energy audit is energy audit report,
the exhaustive picture of building’s total energy consumption
the improvement suggestions and their energy saving potential
cash flow analysis of these improvements
Energy certificate (EPB-directive) gives the observations about the energy consumption and the saving potential and how they affect the energy efficiency factor of the building
In energy certificate the energy consumed so called “estate electricity” is included (HVAC systems, lighting), but the total electricity consumption of the building, meaning for example also the other electrical devises inside the building (like office equipment, TVs etc.) is not included.
Energy audit covers all the consumption in the building  total energy consumption.

Energy audits

Issues related to measuring the energy consumption

Is the energy for the whole building needed even though we are just piloting parts of the building?
With energy audits the most important and profitable actions to save energy can be recognized
Whole building energy data could provide good comparison level and indicate the consumption trend of the whole building and the changes achieved in the pilot areas.
How to recognize the actions where user behaviour have the most impact on? Should this be included into the auditing process?
 Opening and closing the doors and windows, water consumption, switching off the lights etc.
Is the real consumption information sufficient enough to guide the user to choose right actions or should the system be checked during the project by an expert ?
