  4. 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. 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. 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. 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. 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. 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

  38. 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. 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. 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. 41. Classroom; New lighting
  42. 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. 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).
