Make Comfort Sustainable
A smarter, more sustainable indoor climate starts at 25°C. Join us in setting the right temperature and adopting optimal cooling practices for comfort and impact.
Why 25°C Matters
In Singapore’s tropical climate, overcooling is common – but it comes at a cost: discomfort, higher energy use and additional utility costs. It also feeds a vicious cycle, worsening climate change, exacerbating the urban heat island effect and increasing our demand for cooling.
The Go 25 movement, co-organised by the Singapore Green Building Council (SGBC) with the Ministry of Sustainability and the Environment (MSE), and supported by the National Environment Agency (NEA) as well as the Building and Construction Authority (BCA), promotes optimal cooling practices starting with setting indoor temperatures to 25°C — the sweet spot for comfort and sustainability. It’s more than just a number; it’s a call to action for building owners, facility managers, and businesses to lead the way in creating a smarter, more sustainable Singapore.
To support this transition, the Singapore Green Building Council has launched the Go 25 Industry Guide — providing facilities managers and building managers/operators with the know-how to begin implementation of an indoor air-conditioned temperature that is as close to 25°C as possible.
Lead the Shift to 25°C

By pledging, you commit to:
- Go 25 in spaces under your direct operational control (set thermostats to at least 25°C, or as close as possible).
- Encourage your stakeholders to do the same by supporting alternative cooling options like fans or permitting lighter workplace attire where appropriate.
- Display indoor temperature clearly on premises to raise awareness and foster shared accountability.

CDL Elevates Comfort with Go 25
CDL has set 25°C as the indoor temperature standard across its corporate offices, supported by over 100 bladeless Hybrid Cooling Fans that enhance airflow and thermal comfort. To further adapt to warmer settings, CDL introduced a business casual dress code and provides real-time temperature and humidity displays in visible areas across offices. These combined measures ensure staff comfort while reducing reliance on energy-intensive cooling. CDL projects its Go 25 efforts to lower cooling loads by around 20%, cutting an estimated 14,000 kgCO₂e in annual carbon emissions—a tangible step towards sustainable workplace practices.
Smart Comfort at C&W Services HQ
C&W Services HQ enhances workplace sustainability with a suite of Go 25 measures. Real-time temperature displays and zonal controls maintain stable comfort levels while reducing energy use.

Flexible seating allows staff to choose workspaces that suit their comfort preferences, further supporting the initiative. By raising indoor temperatures by just 1–1.5°C, the office achieves significant energy savings—around 12–18% in cooling use. These efforts highlight how thoughtful design and occupant empowerment can create comfortable, efficient, and sustainable workplaces.
Driving Green Habits at GF IIFS
GF Industry and Infrastructure Flow Solutions (GF IIFS) champions the Go 25 commitment through simple, repeatable habits and supportive policies. Go 25 decals at switches and thermostats prompt staff to switch off lights and air-conditioning when spaces are unused. An Eco Team leads by example, embedding sustainable practices into daily routines and inspiring participation through monthly Green Ambassador updates. Initiatives include switching off lights during lunch breaks and maintaining a dedicated recycling corner for paper, plastics, and e-waste. These collective actions strengthen ownership, conserve resources, and reinforce GF’s commitment to shared responsibility and measurable savings across its APAC offices.
