If that's what is predicted for 2025, how populated will our world be by 2050? Scary to think about.

Housing+ by C. F. Møller Architects: Zero-energy design

Housing+ by C. F. Møller Architects: Zero-energy design | A2 World Cities | Scoop.it

C. F. Møller Architects have designed a proposal for the pilot-project Housing+, for 60 zero-energy housing units on the Aalborg Waterfront. The design adhered to stringent energy goals through a combination of architectural design and user-focused technical innovation.

The Housing+ concept sets the ambitious target of a zero-energy housing scheme, which also includes the tenant’s primary household energy consumption. The complex will thus be 100% relying on renewables.

Central to the concept is the use of integrated energy-design to generate the concept of tomorrow’s housing, producing more energy than it consumes. This is achieved by optimizing the inherent passive gains of the main volume, and shaping it to take advantage of the orientation and potential for active solar energy-collection.

 

Visit the link for more images and details on this contemporary, green design that incorporates solar, passive strategies, and on-site renewable energy.

Jodhpur - India's Blue City

Jodhpur - India's Blue City | A2 World Cities | Scoop.it

DB: The aesthetics of architecture within a society not only reveal the communities interpretation of what is considered beautiful or pleasing in appearance but also differentiates between what is considered sacred or important. The symbolic significance of aesthetics in colors, designs and a place of residence can be indicative of socioeconomic standing is within society and what the community values.  Jodhpur, India is well known for the beautiful wave of blue houses that dominate the landscape of a rather dry region. However, it is believed that these blue houses originally were the result of ancient caste traditions. 

 

Brahmins (who were at the very top of the caste system) housed themselves in these “Brahmin Blue” homes to distinguish themselves from the members of other castes. Now that the Indian government officially prohibits the caste system, the use of the color blue has become more widespread. Yet Jodhpur is one of the only cities in India that stands steadfast to its widespread aesthetics obsession with the color blue which is making it increasingly unique, creating a new sense of communal solidarity among its residence.

 

Questions to Consider: How has color influenced the cultural geography of this area?  How are the aesthetics of this community symbolic of India’s traditional past, present and possible future?

Supertrees of Singapore

Supertrees of Singapore | A2 World Cities | Scoop.it

Gardens by the Bay, Singapore’s premier urban outdoor recreation space right next to Mariana Bay Sands, unveiled a new attraction last month – a cutting-edge horticultural mega project featuring 18 towering solar-powered “supertrees” and climate-controlled biomes.

 

These tree-like structures that dominate the Gardens’ landscape with heights ranging between 25 meters and 50 meters, are like vertical gardens that perform a multitude of functions, which include providing plants, shading and working as environmental engines for the gardens.
The Supertrees are home to enclaves of unique and exotic ferns, vines, orchids and also a vast collection of bromeliads such as Tillandsia, amongst other plants.

 

They are fitted with environmental technologies which mimic the ecological function of trees – photovoltaic cells that harness solar energy and can be used for some of the functions of the Supertrees, such as lighting, just like how trees photosynthesize; and collection of rainwater for use in irrigation and fountain displays, just like how trees absorb rainwater for growth. The Supertrees also serve air intake and exhaust functions as part of the conservatories’ cooling systems...
