GBCE is pleased to have supported Missions Étrangères de Paris in the design of their new church in Si Lom, Suriya Wong, Bang Rak, Bangkok, in accordance with sustainability guidelines and features.

Mission

 

GBCE has been working with Missions Étrangères de Paris, PAC Architect, and Bureau Veritas to develop their upcoming new church in Silom, Bangkok, Thailand.
GBCE’s role was to support the team throughout the design process to ensure that sustainability strategies were fully integrated into the project and to provide guidance on the selection of strategies from a cost‐impact perspective.
We also supported the architects and contractor in the selection of appropriate green materials and technologies.

The client had ambitious sustainability goals and aimed to demonstrate its commitment to environmental excellence by implementing a variety of sustainability features creating a pathway for other religious facilities to incorporate sustainable design in the future.The church proudly showcases its sustainable approach through measures focused on energy efficiency, water conservation, and the use of low‐carbon and non‐toxic materials throughout the facility.

Focus: Responsible Materials

As green building and sustainability consultants for the MEP Church development in Silom, we embarked on an exciting partnership with the project team to realise their vision of a sustainable religious facility. Our mission was to integrate sustainability across the design process, with particular focus on the selection and use of environmentally responsible materials.

​

The project strongly prioritised the use of sustainable materials, with 34.38% of the total material quantity meeting recycled-content criteria, reducing resource depletion and environmental impact. In addition, 67% of the total material quantity consisted of green-certified materials, ensuring alignment with recognised sustainability standards and promoting responsible construction practices. Significantly, 100% of all materials used in the project were locally sourced, helping to reduce transportation emissions and support regional industries.

In parallel, the project embraced products with Environmental Product Declarations (EPDs) and rigorously assessed the lifecycle impact of each material. Low-emission interior finishes, non-toxic coatings, and environmentally responsible mechanical, electrical and plumbing fixtures were selected to minimise environmental impact without compromising on performance or aesthetics.

​

This collaboration has resulted in a sustainable church building that proudly showcases a comprehensive approach to energy efficiency, water conservation and low-carbon/low-toxicity materials. In doing so, it sets a meaningful precedent for the integration of sustainability in religious buildings across the region.
