Proposed Topic: BUILDING RESILIENT AND HEALTHY CITIES FOR THE 21ST CENTURY: MAKING IT HAPPEN!
TOMOHIKO AMEMIYA is a co-founder architect of UNITYDESIGN Inc and researcher at Tokyo University. He received his B.A. in Architecture and M.A. in Environmental studies from Tokyo University. While engaging in several domestic architectural projects, he has also been working on foreign projects such as the award-winning Slum Housing Project, Megacity Skeleton, in Jakarta.
Proposed Topic: ‘AFTER FIRE PROJECT’: ARCHITECTURAL PRACTICE IN INFORMAL SETTLEMENT
‘After Fire Project (AFP)’ is a housing prototype project aiming to improve the urban living environment. The project site is a high density residential area located in the center of Jakarta Megacity. This kind of ‘informal’ area is always facing to the pressure of gentrification by formal sectors under the justice such as high-density urban development, environmental cleanup, or flood risk avoidance. In this context, our challenge is to show the scenario how to preserve the good atmosphere of informal community which has been fostered in long time, by a series of micro practices.
Urban housing project has often been failed as the formal structure could not have coexisted with the informal community in peace. How ‘Formality’ and ‘Informality’ would be possible together? AFP is trying to solve this problem by proposing architectural ‘formal’ structure which let ‘informal’ activities sustain into the future.
KEN STUCKE is the sole director of Environment Response Architecture (ERA Architects), a small practice specialising in Green Architecture for the last 20 years. Ken is also a Senior Lecturer in the subjects of Design, Construction, and Building Performance at The University of Johannesburg’s School of Architecture. Ken has also worked hands on as both a contractor and an architect in various countries, ranging from France and England to Botswana and South Africa.
Proposed Topic: ENERGY, WATER AND WASTE EFFICIENCY, COVERING TWO CASE STUDIES
In these two projects, the site and its context are considered more than a place to build the project, but rather the climate, geology, geography and ecology are a resource with which the architecture synthesizes to produce built form.
The architectural design methodology uses a holistic approach, where the building is considered as a whole; an organism or machine, in which every component has an effect upon the other components and on the building as a whole. The building becomes integrated into its landscape in a symbiotic relationship highly intuned to its environment just as any living organism.
Climate is considered an opportunity for synergy to produce comfortable internal and external environments with much less energy expenditure than in traditional architecture. Ken’s architecture responds to the environment in which it is rooted to create comfortable, well lit and well ventilated spaces that are warm in winter and cool in summer.
CHRISNA DU PLESSIS is Associate Professor at the Department of Construction Economics, University of Pretoria. Her research concentrates on developing the principles and guiding frameworks for the practices of sustainable construction and human settlement development, with a focus on resilience and regeneration. She has recently published Designing for Hope: Pathways to regenerative sustainability with Routledge.
Proposed Topic: THE REGENERATES
The Regenerates is a documentary based on handicam interviews with luminaries in the field of Regenerative Development and Design such as Bill Reed, Bob Berkebile and Stephen Kellert. It provides a personal view of the essence of regenerative work and its meaning for both clients and practitioners
MARK OLWENY is Senior Lecturer in Architecture in the Faculty of the Built Environment, Uganda Martyrs University. He research interest is in the environmental performance of buildings in upland tropical environments. In addition, Mark is also interested in architectural pedagogy, and is currently undertaking research on the role of social-cultural factors in the understanding of environmental factors, and how this can be fed back into architectural education.
RODNEY MILFORD is currently Programme Manager; Construction Industry Performance at the Construction Industry Development Board (cidb), and previously Director of CSIR Building and Construction Technology (Boutek). Rodney has played a leading role in the development of SANS 1544 Energy Performance Certificates for buildings, and is supporting the Department of Energy and of Public Works in the implementation of EPCs.
Proposed Topic: SANS 1544 ENERGY PERFORMANCE CERTIFICATES – STATUS AND WAY FORWARD
The presentation examines international trends in the use of Energy Performance Certificates (EPCs) for buildings as a driver of energy efficiency. The presentation then examines the likely implementation of EPCs in public buildings in South Africa, as well as the status of the implementation of EPCs and the way forward.
PAUL MARAIS, after graduating with a BArch from University of the Witwatersrand 1991, has worked as an Architect designing hospitals, before starting his own practice as a sustainable architect working with natural materials, having designed straw bale, cob, adobe and rammed earth energy efficient structures. He is presently researching rammed earth.
Proposed Topic: ECOLOGICAL APPROACH TO HOUSING IN SOUTH AFRICA
This paper presents a case study as part of a Professional Doctorate research project discussing an ecological approach to housing in South Africa, where polymer stabilised earth foundations have been used to support single story rammed earth walls, in a house in South Africa. Rammed earth was chosen as a construction method for its low embodied energy and thermal mass characteristics. The subsurface strata upon which the house was built comprised of clayey, gravely, sandy soils that have resulted as a result of decomposition of granitic rocks. In order to ensure solid founding conditions the foundations were excavated to a depth of one and a half metres before the excavated material was stabilised and backfilled. The material was stabilised to 600mm below foundation height with 2% Portland cement and above that with a 5% polymer bitumen mixture reinforced with horizontal steel reinforcing rods. This foundation avoids the use of reinforced concrete and therefore significantly smaller carbon footprint, while fulfilling the functional requirements of supporting the building and also prevention of rising damp. The polymer has as it major component bitumen emulsion, providing a waterproof layer. Rammed earth walls of 500mm thickness were constructed on the foundation up to 4.2 meters in height and initial observations suggest that the foundations are satisfactory with no settlement or cracking detected. Preliminary findings into the acceptability of rammed earth in southern Africa will be included.
