regroup uses ecotool.asia, a flexible sustainability toolbox and survey platform for the building design process. The focus is on concepts and actions with a high leverage and large effects towards the targeted goals. An economy of means as a basis of the design process is as important as the maximization of the energy efficiency of the building.
- Simple, passive, stable, good-natured systems (more passive, less active systems to control the internal climate)
- Consideration of the economic and technological level in south east asia
- Economically viable measures
- Prevent adverse and promotion of desired effects
- Respect the physical principles
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”
The three main aspects of ecotool are divided into several sub points with individual approaches.
- Wind fostering and use of cross ventilation and buoyancy ventilation
- Sun reducing the heat gain
- Water minimize water use and groundwater preservation, and improve of water quality
- Landscape greened, natural surroundings
- Energy Generating use of renewables energy
- Cooling/ Dehumidification / Ventilation energy efficient systems and healthy living climate
- Light natural light and optimized use of artificial light
- Monitoring & Regulation monitor and control energy consumption
- Overall Design efficient concept and disposition
- Structure sustainable, adequate to climate and functions
- Envelope separation between interior and exterior climate
- Construction/ Materials quality & sustainable materials
Sustainability means a balance between social, economical, and ecological issues and this balance has to be found out individually for each project and location.
- long-term economic model: construction, operational, energy
- maintenance, and replacement costs
- longevity of materials
- long-term development, possibilities future transformations
- high level of architectural quality
- consideration of the physical, cultural, and social context
- reduces global CO2 emissions, reduced ecological footprint
- energy efficiency, reduced energy consumption
- use of renewable resources (active and passive)
- grey energy minimization, use of recycled content materials
