4. Objectives: Annex 1 - A1.4 2
The project will demonstrate the substantial Energy Savings
20 % from energy consumption transformation behaviour
5 % from smart ICT energy management that can be
achieved in public buildings through the use of services
enabled by ICT in particular by supporting the user
transformation behaviour.
The social acceptability of energy efficiency will be enabled
by the motivated education of the users, playing the SAVE
ENERGY Serious Game in different creative and
compelling settings.
Furthermore, the eco-conscious educated user will be
empowered with real time ubiquitous information and
decision making guidance that will enable and motivate the
interaction leading to energy efficiency.

21. Saving Energy by the user
behavioral change
The key objectives of the Helsinki pilot is to measure in
real time all the relevant energy information on the
consumed electricity, heat and water consumption
by using the new high-tech wireless sensor network
system,
by transferring the data from the existing building
management system and
from the separate transferable measurement units.
All the measurements have been collected to the virtual
server generating the instructions to save energy and
the simple and understandable displays to the users at the
schools (kitchen personal, janitor, teachers, pupils,
technical experts) in order to achieve the permanent
behavioral change in saving the energy.

25. Kitchen is a big consumer !
Professional public kitchen
In Finland there were about 22.000 professional public kitchens in 2008
Of which more than 9.000 (42 %) were preparing 200 meals per day
Of which more than 4.600 (21 %) were distribution & heating kitchens
without own production
Besides there were about 1.600 central kitchens preparing meal
portions for distribution & heating kitchens and for homes
At Ala-Malmi and Pihkapuisto, there is a very small personnel, only 2 – 3
persons, who can effect on the energy consumption at the kitchen by
The working methods in each phase (maturing effectively)
The correct timing, filling the owens and using all the machines
properly
The kitchens (having several really high power machines) are consuming
about 20 % of the total electricity energy at schools

26. Evaluation of the kitchen energy consumption at
Ala-Malmi and Pihkapuisto
The goals (from the energy saving point of view):
To analyse present food preparation methods and the use
(timing, filling) of equipment and machines
To analyse user logistic operations at the kitchen
To evaluate potential energy savings
To evaluate possible proposals of standard developments,
improvements and efficiency in the food preparation and in
dining (preservation, preparation of food, waiting, dining,
returning dishes, washing and cleaning)
To find out best practices to save energy at the kitchen

27. The evaluation has a critical eye on :
The cost savings (water, electricity and heat energy
consumption) notifying also the environmental and hygienic
issues and the valid standards, instructions, laws and
decrees.
Appropriate operations at kitchen and activities and
knowledge of the personnel to use the equipment correctly
Efficient and appropriate level of equipment (new
technology) available at the kitchen (inductive owen,
combined owen, intelligent combi pot, maturing processes,
high speed freesing, energy economic washing machine,
etc.
Ventilation of the kitchen room

36. Ideas of Development (1/2)
– Preparing the food:
• When using the kitchen machine, use them correctly
• When to switch the kitchen equipment on ?
• Use only the shallow palets for food preparation in the owen
• Benefit the after heat in the owen
• Maintenance of the kitchen equipment is important to keep them
in good condition
– Serve the food effectively
• It will be more effective when the 2 dining set ups are very close to
each others
– Other
• HVAC should be switched off automatically

37. Energy efficient professional kitchen
Frigerator and Freezer Owen
Keep the doors closed Check the maturing devices
Freezer device is not a cold storage Clean up immediately after the usage
Combined owen Serving equipment

characteristics of the equipment Switch it on about 30 – 50 min
Modify the old receipts according to before serving
the new equipment
Dishing machine
Benefit the after heat
Feed it correctly
Use only full palettes
Dried dirty dishes should be first pre
washed
”Kouluta, opasta ja vaadi.” ”Energia tehokkaan toiminnan ydin on oikea aikaisuus”

38. Ideas of Development (2/2)
– LayOut
• Reorganize the dining room.
– Economic responsibility to the Food Operator
• The Food Operator should be responsible for the born costs of the
water and electricity consumption
– Menu
• Healthy and cheap food, what about the preparation of the food and
energy efficiency ?
– Lighting
• Benefit the day light as much as possible
– R&D tips for the manufacturer of the kitchen equipment
• Vertically flexibly moving shallow door for owen would also save
energy

39. Save Energy / Saving potentials in Kitchen
Proposals of Developments dealing with kitchen Equipment and
food preparation
1 Using effectively the after heat in the owens
2 Limiting the unnecessary use of high power equipment
3 Using mainly the shallow palets in food preparation
4 Loading the high power equipment properly and effectively
5 Replaced investment of the old and energy consuming equipment
6 The effects of Menus on energy consumption
7 Food operator (Fazer Amica, Palmia) should have more
responsibility on the consumption costs of electricity and water
8 Logistical effluency and timing at schools
9 Equipment training for users, scheduled maintenence

40. How to activate the users ?
Much greater energy savings could be achieved by changing the
user’s energy saving habits than by technical solutions
Real time information about the energy consumption giving to
the user with the display unit
Giving instructions to users about correct and appropriate use
of lighting
The users get acquainted with the new lighting technology and
transfer this information outside the school

41. Classroom; New lighting

42. Energy consumption based on lighting:
In Finland all the lighting is consuming about 10 % of the total
available energy (Motiva, 2009).
Lighting at school building is consuming the energy more than 20
%.
Large amount of lighting
Unefficient control methods
The lights are on with full power all the day
How to save energy in lighting ?
Correct amount of light, in right time, into right place
Energy efficient and lifelong lamps and interfaces
Use highly profitable (beneficial) lighting
Use control actively (based on motion, daylight, tasks, etc.)
EuP directive 2005/32/EC removes incandescent lighting away

43. 1. Pihkapuisto, old part;
Multisensor lighting at the classroom:
q The lights at the classroom are controlled by using multisensors
including a light sensor and a motion detector.
q Depending on the availability of daylight the light sensor (photocell
sensor) automatically reduces/increaces the amount of electrical
lighting and keeps the illuminance level constant.
q The motion detector switches the lights off when the classroom is
vacated (set to switch the lights off after 10 min. of absence).
q Two multisensor units are mounted into the luminaires. These master
luminaires controls the illuminance level of the slave luminaires that
are on the same row/luminaire group. The luminaires are equiped with
T5 45 W and 25 W fluorescent tubes and electronic ballasts (DALI).
q The calculated energy consumption is about 439 kWh/a (assesment
mady by using standard EN 15193, typical values for a classroom).
