Improving Outdoor Thermal Comfort at JID

Jurong Innovation District is a 620-ha next-generation industrial district developed by JTC to support the transformation of manufacturing industries. The estate spans across five precincts, including Bulim, Bahar, Cleantech Park, Tengah and NTU. As a car-lite district, JID features an 11km Sky Corridor where the community would be connected to key transport nodes by walking, cycling or future autonomous vehicles.

Challenges

With the high air temperatures and relative humidity in Singapore, energy efficient climate adaptation measures are required to cool the outdoor spaces along the Sky Corridor. This is especially critical in areas of congregation (e.g. plazas) and thoroughfares to improve the experience of users and encourage higher footfall. Proposals can include active and/or passive solutions that improve outdoor thermal comfort while minimizing energy use and emissions.

1. Proposes a sound methodology to improve thermal comfort
2. Solution is able to track outdoor site conditions such as weather and occupancy (via sensors, etc)
3. Proposal includes a measurement plan
4. Proposal includes anticipated energy use and carbon footprint
5. Proposed solution is able to respond dynamically ( to external factors hourly (min)
6. Proposed solution is able to be monitored remotely and controlled
7. Proposal ensures no adverse impact on environment (i.e. air) quality
8. Solution has minimal to no waste heat generation
9. Proposal includes a desktop study (high level approximation will do) on the scalability, cost and space requirements should the system be implemented at scale.  

The envisioned solution shall:

• Effectively cool outdoor spaces to improve thermal comfort of users (measured via PMV)
• Minimize energy use and carbon footprint while achieving the desired cooling effect
• Automatic adjustment (hourly or less) based on outdoor site conditions, including weather and occupancy
• Be scalable, ensuring cost and space effectiveness
• Allow for remote monitoring and control, with potential to interface with JTC’s estate open digital platform (where applicable)
• Ensure safety and continuity of operations, such as through equipment analysis for quicker troubleshooting of operational issues on the ground and minimize turnaround time
