OPEN HOUSE methodology is not just a tool to evaluate a building’s sustainability once it is completed, but it should be used as a design tool in order to ensure that the constructed buildings are truly as sustainable as possible. The engineers, like architects, should act as coordinators in the whole design and implementation process and for this reason deep understanding of the OPEN HOUSE methodology is necessary.


Architecture must utilise holistic, integrative methods from the smallest scale up through

that of city and regional planning, never forgetting that buildings, landscapes, the natural

environment and infrastructures are all essential elements in the continuous creation of a

sustainable future. A careful and considerate design of forms, geometry and spatial

strategies, married with the appropriate materials, equipment and functional distribution

can reduce the use of resources, greenhouse gas emissions and overall environmental

impact by 50% to 80%.


Sustainable by Design: Strategy

• Sustainable by Design begins with the earliest stages of a project and requires

commitments between all the stakeholders: clients, designers, engineers, authorities,

contractors, owners, users and the community.


• Sustainable by Design incorporates all aspects of construction AND future use

based on full Life Cycle Analysis and Management.


• Sustainable by Design optimises efficiency through design. Renewable energies,

high performance and environmentally benign technologies are integrated to the greatest

practical extent in the project conception.


• Sustainable by Design recognises that all architecture and planning projects are

part of a complex interactive system, linked to their wider natural surroundings, and reflect

the heritage, culture, and social values of the daily life of the community.


• Sustainable by Design seeks healthy materials for healthy buildings, ecologically

and socially respectful land-use, and an aesthetic sensitivity that inspires, affirms and



• Sustainable by Design aims to significantly reduce carbon imprints, hazardous

materials and technologies and all other adverse human effects of the built environment on

the natural environment.


• Sustainable by Design endeavours to improve the quality of life, promote equity

both locally and globally, advance economic well-being and provide opportunities for

community engagement and empowerment.


• Sustainable by Design recognises the local and planetary interdependence of all

people. It acknowledges that urban populations depend on an integrated, interdependent,

and sustainable rural-urban system for their life support systems (clean water and air, food,

shelter, work, education, health, cultural opportunity, and the like).


• Sustainable by Design endorses UNESCO’s statement that cultural diversity, as a

source of exchange, innovation and creativity, is as necessary for humankind as

biodiversity is for nature.
