Singapore, June 2025 — Kingspan Insulation has released a new white paper titled The Operating Energy, Cost, and Carbon Benefits of Insulation, highlighting the measurable impact of insulation in reducing energy demand and emissions in tropical climates.
The study, independently modelled by GreenA Consultants, focused on a simulated 30,000 m², four-storey inpatient hospital located in Singapore. Two building envelope configurations were compared: a baseline design, and another with enhanced design using Kingspan insulation products.
Key findings include:
- 17.2% reduction in cooling energy demand with the additionally insulated building envelope
- 6.3% total building energy savings annually
- S$118,500 estimated annual energy cost savings based on 2024 energy prices
- 152.1 tonnes less CO₂ emissions per year, equivalent to 380,000 US miles driven by a typical passenger vehicle
The white paper compares a baseline design with ASHRAE 90.1 minimum performance to a specification incorporating:
Kingspan Kooltherm® K20 Concrete Sandwich Board (external walls)
Kingspan Therma™ TR26 (roofs)
Kingspan Kooltherm® K10 Soffit Board (basement ceilings)
These upgrades lowered the building’s U-values substantially, leading to a notable drop in cooling demand — a key factor in Singapore’s energy profile.
