TONGJI Sustainable Campus Economized Campus Resource-efficient campus. Tongji University (China) Outlook

Transcription

1 ISCN 2008 Best Practice TONGJI Sustainable Campus Economized Campus Resource-efficient campus Hongwei Tan Tongji University (China) Outlook Tongji University has been taking the lead of Sustainable campus in China since 2003, and getting consensus through the participation of faculty, students and staff on resource-efficiency. The resource-saving solution has been approached through three ways of technology, management and education The Campus demonstrates a series of projects regarding resource and energy saving. Now the campus has been became a mode in China

2 Sustainable Development in China 4 S + E Saving Energy Saving Land Saving Water Saving Material Environment protection Sustainable Campus Demonstration in Tongji University Total area Total members: 67,000 JD campus SP campus HX campus CF campus HD campus HB campus ZW campus Shanghai Map Seven campuses distribute over Shanghai Total energy consumption over 20,000 tec. / y tce.= ton of coal equivalent = 0.65 toe.

3 Four Functions of the Sustainable Campus in TONGJI Univ. Community Service TONGJI Sustainable Campus Three approaches TECHNOLOGY MANAGEMENT EDUCATION 3R Technology Reduce Recycle Reuse 4S+E Technology Design & Management Guideline Efficient Operation Measurement & solution Energy Audit Education curriculum Student activity Campus Life Style Demonstration Management Participate in

4 Resource-efficient technology in Campus Technology Category Technology application Eco- Planning Green Building Efficient Building Equipment System Campus Energy Management System Water Recycle Renewable Energy Eco-Campus Planning, Green Campus Evaluation Thermal insulating, New Material, Roof Greening Eco-renewal of Existing Building Nature / Displacement /Hybrid Ventilation, Efficiency Light, Ice Storage System, Cooled ceiling Heat recovery HP Building Energy Management System Energy Audit Wastewater Reuse, Heat Recovery Artificial Wetland, Rainwater Reuse Solar Thermal Energy, Geothermal Heat Pump Cooled Tube Pre- Air Conditioning Best practice projects in Tongji Univ. Student bus hose Wastewater Reuse center Eco-Building New Eco-Building Swimming Pool Hall (Historic Architecture New ES Building Efficiency-Lighting Eco-Building (Historic Building) Eco-Lab. SP Campus Map

5 Demonstration Project for Renewal Building Wen Yuan : Historic Building Bauhaus Style Education Building In the Campus (TONGJI, China, 1953) Original Bauhaus Dessau Education Building (Germany, 1926) Renewal of Historical Buildings with Eco-Technology

6 Wen Yuan : Historic Building Low-E window Thermal insulation(inside wall) Rain water use Efficiency Lighting Roof Greening Renewable energy : GSHP in Campus (Ground source Heat Pump ) Fitting the regional condition Fitting the thermal load character of building Fitting the operation

7 Eco- Refit for Wen Yuan Building Roof Greening Thermal Insulation Efficiency Lighting BA System Solar Energy Low-E window Sun Shading Rain Water System Cooled Ceiling Geothermal Heat Pump Eco-Refit for Tongij hall- A Historic Building

8 Energy-efficient Technology for Tongji Hall Clooled tube for air conditioning Natural Ventilation Displacement Ventilation Hybrid Ventilation System for High-rise Building Natural & Mechanical Ventilation System for Atrium Increased initial cost can payback Within 3.5 year. Ice storage air conditioning Shift the peak load More flat load curve The system will be the contribution for DSM of Power supply

9 Climate zone in China Different standard for different zone Energy Saving on Campus facilities Solar thermal Energy for hot water system Bathhouse wastewater reuse and heat recovery Efficiency Lighting system

10 Wastewater reuse and heat recovery in Bathhouse Process of Bathing Wastewater Reuse Treatment Bathing Wastewater Reuse Treatment process Wastewater Reuse Artificial Wetland for wastewater treatment Wastewater Plant Reuse water Waterscape in the Campus Artificial Wetland

11 100% of the Irrigation water on campus comes from non-tap-water sources Saving water resource of 300,000 T/a Energy management System Non Measurement = No Management

12 Campus Energy Management System Decision Energy consumption Cost Analysis Efficiency analysis Data Management Energy consumption statistics Efficiency analysis Alarm Data Specialist Operation Operation record Energy Monitoring Equipment management Data collection Campus Energy Management System Sub-Campus Layer Building layer Data base SP Campus Tongji Univ.
