nachhaltige Architektur für Südost Asien

sustainable design for southeast asia

Sustainability means a balance between social, economical, and ecological issues and this balance has to be found out individually for each project and location.


    • economic Performance
      • long-term economic model: construction, operational, energy, maintenance, and replacement costs
      • longevity of materials
      • prefabrication and modularisation
      • reducing to the maximum, eliminating the superfluous
    • social Performance
      • long-term development, possibilities future transformations
      • high level of architectural quality
      • satisfies human needs and supports healthy lifestyle
      • consideration of the physical, cultural, and social context
      • traditional, local architecture design
      • foster biodiversity
    • ecological Performance
      • reduces global CO2 emissions
      • progressive energy performance
      • energy efficiency, reduced energy consumption
      • use of renewable resources (active and passive)
      • water preserving, supports local aquifer recharge
      • minimal earthwork
      • reduced ecological footprint
      • waste minimizing: reuse, recycle
      • grey energy minimization, use of recycled content materials

Sustainable architecture

Sustainable architecture seeks to minimize the negative environmental impact of buildings by enhancing efficiency and moderation in the use of materials, energy, and development space.
Generally sustainable architecture reduces global CO2 emissions, energy consumption, and material waste. Green buildings, also known as high performance buildings, are intended to be environmentally responsible, economically profitable, and healthy places to live and work.

    • Value for developer, investor, and owner
      • positive contribution to global climate
      • reduce greenhouse gas emission & resource efficiency
      • higher building quality and lower maintenance costs
      • less electricity / water use and lower utility bills
      • optimize the investment / increase property value
      • prestige and high quality
      • good indoor environment quality and non-toxic material
      • healthy living environment


There are meanwhile many different rating system and lables for green/ sustainable Buildings Design available. Some of them specializes on a specific building typology, some concentrated only on partial aspects, some closely linked to a local region.

International labels like LEED are a very good possibility to compare and rate properties on a portfolio overview in terms of sustainability.
These all-embracing labels try to generate an objective rating as much as possible and therefore these models are very extensive and complex. They are more rating systems than guidance tools and generate often a quite big effort for the planning process.




ecotool is a adoptable system to improve the project sustainability in the context of southeast asia with the main goal to improve the living quality, optimize the investment in a long term thinking combined with a responsible use of natural resources.

ecotool is not a label and rating tool, it’s a flexible toolbox for the design process of a building. In the main focus are action and concepts with a large leverage effect and a big impact one of targeted goals.

ecotool system is based on three aspects:


Context - Passive Energy Performance

Preserving and adequate handling as well as usage of existing resources.



Usage - Active Energy Performance

Reduction and optimization of required building energy.



Building - Static Building Performance

smart concepts and appropriate constructions,
“form follows climate and function”
