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.
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.
Join the national movement of industry leaders committed to building a smarter, more sustainable future. The Go 25 pledge is a powerful demonstration of your organisation's dedication to balancing occupant comfort with environmental sustainability.

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.
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. Solar films on windows mitigate heat gain and glare, protecting interiors from strong sunlight. 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.
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.
As Singapore’s largest air-conditioner retailer, Gain City has been a strong advocate for sustainable cooling and energy efficiency. Building on its long-standing partnership with the National Environment Agency (NEA), which began in 2003 with the first in-store “Green Corner” showcasing energy-efficient appliances. Gain City was among the early supporters of the Go25 initiative and took the pledge as a natural extension of its sustainability journey.
Gain City has implemented Go 25 across its showrooms, offices, and megastore, training staff to maintain air-conditioning at 25°C and above, enhance ventilation, and educate customers on sustainable cooling practices. Early results show up to 12% energy savings, reinforcing the impact of responsible cooling.
Through initiatives like air-conditioner recycling, trade-in programmes, and public education campaigns, Gain City continues to promote sustainable living and support Singapore’s broader climate goals.
At Excel Precast, implementing the Go 25 initiative was more than an operational change — it was a mindset shift towards sustainability. Guided by the 5E Principles (Educate, Engage, Encourage, Empower, and Enforce), the company took a people-first approach to embed energy-conscious habits across its workplace.
The journey began with education, helping employees understand how setting indoor temperatures at 25°C supports the Singapore Green Plan 2030 and contributes to the company’s broader ESG goals. Open dialogue and engagement sessions helped address initial concerns, while encouragement and small wins built confidence and momentum. Practical measures such as additional fans, plants and feedback channels empowered staff to adapt comfortably.
With consistent reinforcement from management, Go 25 evolved from a trial into an enduring workplace culture. The initiative has strengthened team unity and reaffirmed Excel Precast’s belief that sustainability begins with people — one mindset, one degree, and one team at a time.
At ebm-papst, we proudly support Go 25 by implementing IoT-enabled Smart Ventilation on Demand. These sensors monitor occupancy and air quality, and automatically maintain indoor temperatures at 25°C or higher, ensuring optimal comfort and energy efficiency.

In line with our commitment to maintain indoor temperatures at 25°C, Republic Polytechnic (RP) has taken comprehensive steps to implement optimal cooling practices:
RP has adjusted air-conditioning settings in all transient and high-traffic spaces—such as the Agora, RPC (Republic Polytechnic Centre), and TRCC (The Republic Cultural Centre) common areas—to the recommended 25°C.
We are strategically implementing innovative hybrid cooling solutions across classrooms and offices. These systems combine wall-mounted and bladeless ceiling fans with air-conditioning maintained at 25°C. This approach maximizes thermal comfort for our community while minimizing the overall cooling load. This transition is a key part of our ongoing sustainability roadmap.
To fully embody the Go 25 spirit, RP displays real-time temperature readings in key locations to raise awareness and encourage shared responsibility among students and staff.
Terra-X is committed to sustainability through our Go 25 initiative, setting office air conditioning to a minimum of 25°C. With prominent posters throughout our office, we're reducing energy consumption and operational costs while supporting Singapore's environmental goals.
Beyond energy savings, Go 25 reflects a holistic approach to workplace wellness. Our office aquarium fish thrive in the stable 25°C+ environment, as temperature fluctuations can stress these sensitive creatures.
By maintaining this optimal temperature range, we ensure our fish live comfortably while advancing our sustainability mission. Go 25 demonstrates that environmental responsibility and compassion for our workspace ecosystem go hand in hand.
