Light as a service: the ‘pay-per-lux’ system

Schipholl Airport, Lounge 2: The specially developed sustainable Philips luminaires, which hang in an attractive pattern in the transfer hall above the passenger’ heads, comply with the stringent requirements of the circular economy concept. These luminaires have been specifically designed to allow fast and easy repair or replacement.

Turntoo developed Light as a Service and Circular Lighting for Philips: a service in which you buy light without an investment, but with the best products and hassle free. The installation remains Philips’, who is motivated to the utmost to create products they can reuse: a closed system for used materials. Philips retain ownership of the lights and take care of the reuse, refurbishing or recycling to ensure customers get maximum value from the lighting system. For customers this results in potential maintenance cost savings of 60% and 20% more cost effective upgradability.

Overview on bio-based building material made with plant aggregate by S. Amziane & M. Sonebi

hemp shiv (the woody core of the stem of the hemp plant) is probably the most widely used in alternative or eco-friendly building materials in Europe and is also representative of most of the aggregate coming from the stem of an annual crop. This is usually mixed with a lime-based binder and the resultant bio-concrete is known as hemp-lime

(…) plant based materials have a valuable benefit for health, ecologic, comfortable habitat (moisture management, thermic and acoustic) and sustainable materials (…) can be qualified as environmental-friendly and efficient multi-functional (…) The use of crushed hemp (shiv), flax and other plants associated to mineral binder represents the most popular solution adopted in the beginning of this revolution in building materials (…) in particular, for hemp, for which the corners of the market are as varied as fibers for the automobile industry, foodstuffs for the grain or indeed the wood of the stem for construction (…) Indeed, many projects aim to create construction materials using one or more forms of lignocellular matter as a reinforcement to the structure rather than as a lightweight aggregate with an insulating purpose (…) More recently, projects used various sources of bio-aggregates, such as wood, coconut, sisal, palm, bamboo, or bagasse (…) Bio-based aggregate are coming from the stem of plants cultivated either for their fibers (hemp, flax, etc.) or for their seeds (oleaginous flax, sunflower, etc.)

Agro-concrete: “A mix between granulates from lignocellular plant matter coming directly or indirectly from agriculture or forestry, which form the bulk of the volume, and a mineral binder”

Hempcrete is a mixture, in very changeable proportions, of two very different components: a plant-based granulate and a hydraulic and aerated setting binder. It exhibits multiphysical behaviour which is unusual in the domain of construction materials. Indeed, the particles of hemp wood are characterized by a high degree of porosity which results in a high capacity to deform, absorb sounds and have hygrothermal transfer ability: this is one of the essential characteristics which set hempcretes apart from tradition mineral-based concretes for which the granulates are considered non-deformable (…) the variability of the behaviour depending on the formulation enables us to adjust and optimize the performances of this material for diverse applications as a roof filling material, in walling or as flagging (…) It can undergo differential compression, contraction or dilation with no apparent cracking (…) Hemp-based materials are considered as phase-change materials (PCM): the thermal behavior reduces the amplitude of the variations in the ambient air temperature, whilst improving the thermal comfort by bringing down the surface heat of the material. Thus, the use of such materials is an excellent means of passively regulating the indoor temperature, and thereby decreasing the building’s energy requirements (…) these materials are able to improve summer and winter comfort, and stabilize the indoor temperature between day and night, whilst preventing the phenomena of condensation and dampness on the walls (…) 1.8 tons of CO2 are sequestered for every ton of hemp shiv used (…) there is a favorable impact on the greenhouse effect; the hempcrete wall constitutes an interesting carbon absorber for a duration of at least 100 years (…) Some studies have shown that wetting/drying cycles, used to simulate natural variations of humidity, had an influence on the mechanical and thermal properties of hempcretes (…) fungi may also appear at the surface of materials

Oslo Architecture Triennale, Enough: The Architecture of Degrowth

Image available here

The theme of the 19th Oslo Architecture Triennale, Enough: The Architecture of Degrowth plays with the explosive power of this word to open up new debates into how much the pursuit of economic growth has damaged the environment and of the need to try out new solutions in architecture (floornature). The curators (Matthew Dalziel, Phineas Harper, Cecilie Sachs Olsen and Maria Smith) argue that “architects are mistaken if they believe they can confront the climate crisis by merely rethinking the way they design buildings. Instead, it is the economy and the very armature of our civilisation that requires a rigorous redesign.” (AR)

You must be brave to peel back the skin concealing the ugly ribcage of our economic system, its guts ingesting gas, coal, trees, animals, minerals, water and clean air and flatulently defecating an endless stream of clothes, plastic bags and neat packets of processed food. (AR)

The program develops in the “Academy,” the “Theatre,” and the “Playground,” until November 24. (Official site)

Wikkelhouse | Fiction Factory

Fro the company’s site:

The base of the Wikkelhouse is ‘virgin fiber paperboard’, which is made from Scandinavian trees. This so called goldboard, is wrapped around a huge mold, with a method patented by RS Developments, while environmentally friendly glue is added. This creates a tough and insulating sandwich structure. By this wrapping process a heat insulation and construction method are integrated in a sustainable way. Afterwards each segment is finished with a protective film and a shell of wooden slats.Wikkelhouse meets the criteria for temporary or permanent housing. It is about eight times more durable than traditional construction.

The many faces of sustainability

Image available here

Sustainability is referred to as related to…

  • energy efficient high-tech, low-tech, or vernacular strategies
  • health, well-being, and quality of life issues
  • an analogy to natural forms or from processes in natural systems
  • performance over appearance
  • appearance over performance
  • intelligent and responsive materials, renewable, recyclable, biodegradable
  • sensory perception
  • resilience and circular economy
  • not building at all and instead promote virtualization
  • ecological footprinting and consumerist lifestyles
  • best practice guidelines, assessment methods

All above-mentioned concepts are context-specific and inevitably contested. Enacting and translating sustainability in arch design practices can occur in different stages of the design/build process:

  • during the design brief phase that defines the sustainability targets: translating the concept of sustainability into design practices, recognizing the controversial issues to tackle/ those is in charge of giving directions should ask those bidding to work on giving meaning to these goals
  • when analyzing the ways in which design strategies are constructed between the distinct vocational design actors
  • when establishing supposed equivalences between projected and actual design
