  1. Environmentally Friendly StationsThe Osaka “Eco Station” and Management Techniques West Japan Railway Company Shigeki Naka

  2. Agenda 1. Overview of JR-WEST 2. Osaka Station City as “Eco Station” 3. Action for eco-station realization ・ Analysis of electric power consumption in the station ・ Visualization of electric power consumption in the station ・ Daylight simulation ・ Thermal environment simulation ・ Creating Guidelines for Eco Station Design

  3. Overview of JR-West (Data 2012.4.1） Sanyo-Shinkansen Operating km: 644.0 km No. of Cars: 1,045 cars JR-HOKKAIDO Kanazawa JR-EAST JR-WEST Shin‐Osaka Okayama Hiroshima Osaka JR-CENTRAL Hakata JR-SHIKOKU JR-FREIGHT JR-KYUSYU Ordinary railways Operating km: 4368.7 km No. of Cars 5,636 cars

  4. Osaka Station City Osaka is core station in west Japan area Number of Users: approx. 800,000/day Open 1874 Rebuilt 2004 – 2011 Reopening May,2011 Osaka Tokyo Kyoto

  5. Environmentally Friendly Energy saving buildings Roof top planting Roof top garden Roof top garden Solar panel Use external light Dry mist Waste recycling Rain Water recycling system

  6. Energy Saving Buildings High performance facilities To reduce the impact of the afternoon sun, elevators and toilet are located on the west side. Metal coating outer inner Dry air Spacer containing desiccant Low-e glass Office floor - Lighting using daylight - Motor roll screen (lobby window)

  7. The Use of NaturalEnergy Solar Panel (total 133kW) Access to parking: Solar Panel (26kW) Platform roof : Solar Panel (103kW) South Gate Plaza: Solar Panel (4.16kW) Solar and hybrid generation Solar generation Hybrid generation (Rooftop garden) (Rooftop planting) Batteries charged from solar panels (84W), and used for night lighting. Batteries charged from hybrid generators (solar 84W, wind 64W), and used for night lighting.

  8. Effective Use of Water Rainwater and recycled water use to flush the toilets 870m3/day tap water Recycled water 70% Rain water Basement storage tank

  9. Rooftop Gardening Rooftop garden and green wall To reduce heat island effect, lots of green is arranged. Total Green Area North Gate Building: 1,741m2 South Gate Building: 414m2

  10. Recycling of the Waste Waste is separated into 20 different classifications in the buildings. Waste generated daily is separatedinto 20 different classifications and 17 of these items are recycled. 17 items: Recycle Food, fish, oil, polystyrene form, news paper, magazine, copy paper, cardboard, etc. 2 items: Thermal Recycle Food waste, other burnable trash 1 items: Landfill Other non-burnable trash

  11. Agenda 1. Overview of JR-WEST 2. Osaka Station City as “Eco Station” 3. Action for eco-station realization ・ Analysis of electric power consumption in the station ・ Visualization of electric power consumption in the station ・ Daylight simulation ・ Thermal environment simulation ・ Creating Guidelines for Eco Station Design

  12. Analysis of Electric Power Consumption in the Station Measurement Station （Data 2012.4.1）

  13. Electric power of lights accounts for about half of all power consumed. Analysis of Electric Power Consumption in the Station other Electric water heater 2% 11% Lights in Station home Air-conditioning equipment 36% 13% 10% escalator 17% 9% elevator 2% Lights in Station building Vending machine and Ticket vending machine Common features of Each station! Okubo Station 【933kWh/day】

  14. System for the Visualization Measure Point Data Center Linuxbox Multi circuit meter The Internet Data Data collection server 3G 3G/WiMAX Router User / Manager Smart phone PC Tablet

  15. System for the Visualization of Electric Power Consumption This has helped us to chart on an hour by hour basis.

  16. Daylight Simulation Almost identical! Fig. Simulation Result Fig. Actual measurement value after completion

  17. Increase in temperature (outside temperature +6 degrees) Temperatures have not risen Before After Settsu-Motoyama Station Thermal Environment Simulation

  18. Creating Guidelines for Eco Station Design

  19. Electricity edition Main Contents of Guidelines • Illumination criteria • an idea for illuminationat lighting areas in the station • an idea for selecting energy-saving lightning appliance • an idea for energy-conservation of escalators • and air-conditioning equipment, etc. Water edition • an idea for selecting energy-saving apparatus • an idea for utilizing rainwater and sump water, etc.
