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

Some results of Energy Audits

Pihkapuisto Explanation

heat 16 % savings, need for investements about 6100 €

electricity 4 % savings, need for investments about 1600 €

water 4 % savings, need for investments about 500 €

How ? More LED lights, lighting based on the usage of the space

More accurate and reduced use of heated water (savings 4500 €/a)

Reduction of the usage times of the HVAC machine and reduction of the temperature of the incoming air

Increasing the temperature at the frigerator

More accurate heat recovery, shutting the doors at wind boxes

Saving nozzles for water valves

Powering off the computers at the classrooms for night time

What happens if we change and improve the lighting in an workplace ?

Measuring energy savingsEnergy indicatorsEnergy audit vs. energy certificateEnergy audit Issues related to measuring the energy

consumption

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?

1) we need to know what to measure 1) what are the indicators (Task 1.2 Save Energy Concept, Task

3.3 Performace indicators…?)2) How to measure the pilot buildings’ energy performance

1) Energy audits (Task 2.3 Energy audit methodologies and procedures)

3) The measure of the user behaviour1) 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

Helsinki pilot

•Energy audits currently under work•Whole building and total energy consumption included into the audit

Luleå pilot•Energy audit done in December 2008•Whole building and total energy consumption included into the audit

Lisbon pilot•Simulations for Energy Certificate (EPBD) done•Certificate don’t include the total energy consumption, just the ”real estate consumption”•Plan is to measure the total consumption with ISA’s equipment

Manchester pilot

• Monthly consumption data available for the whole building• ???

Leiden pilot

•???

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 ?
