1 Environmentally Friendly Stations The 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 Okayama Hiroshima Hakata No. of Cars 5,636 cars 5,636 cars Ordinary railways Sanyo-Shinkansen Operating km: km km No. of Cars: 1,045 cars 1,045 cars Operating km: km km (Data ) JR-WEST JR-EAST JR-CENTRAL JR-FREIGHT JR-SHIKOKU JR-KYUSYU JR-HOKKAIDO Shin ‐ Osaka Osaka Kanazawa

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

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

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

7 Solar Panel (total 133kW) South Gate Plaza: Solar Panel (4.16kW) Platform roof : Solar Panel (103kW) Access to parking: Solar Panel (26kW) Solar and hybrid generation Solar generation 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. Hybrid generation (Rooftop garden)(Rooftop planting) The Use of Natural Energy

8 Recycled water 70% 870m 3 /day Rain water tap water Rainwater and recycled water use to flush the toilets Basement storage tank Effective Use of Water

9 Rooftop garden and green wall North Gate Building: 1,741m 2 South Gate Building: 414m 2 Total Green Area To reduce heat island effect, lots of green is arranged. Rooftop Gardening

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

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 Station Omi- hachiman Station Nada Station Okubo Station Kusatsu Station Okayama Station Number of Users [thousand/ day ] 34442855118 Electric power consumed [kWh/day] 9211, ,4935,721 Measurement Station ( Data )

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

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

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

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

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

18 Creating Guidelines for Eco Station Design

19 Main Contents of Guidelines  Illumination criteria  an idea for illumination at 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. Electricity edition Water edition  an idea for selecting energy-saving apparatus  an idea for utilizing rainwater and sump water, etc.
