Research abstract – Thermal Archipelagos




Urban expansion should base not only on developing new source of primary energy, but also rethink its consumption pattern and develop alternative strategies for secondary energy. The London Mayor’s Decentralized Energy Capacity Study (2011) suggests that by 2030, 22% of London’s heat and power could be efficiently generated locally, where the heat is distributed via heat networks.1


The investigation focuses on infrastructural intervention that fosters thermal exchange (energy) and investment incentives (economic) and how this provide strategies for new types of urban expansion.




The objective is to develop an instrumental architecture form deployable in a variety of contexts, with variations in design details driving a range of material production (prototype development and revenue generation) and immaterial productions (knowledge exchange and business opportunities).2


Surplus heat generated via a series of infrastructural network should enable densification of urban fabrics. Densification is hypothesized to be productive as they open up ways to exchange and cascade energy consumption. Various heat-demanding programmes can be introduced foster the social interactions and development of communities. On a metropolitan or territorial scale, the formation of clusters in strategic locations contributes to a larger network of exchange (an energy grid / innovation clusters grid).




In the context of East London, Royal Victoria Dock is chosen to be the testing ground. The huge volume of water suggests resourceful heating and spatial capacity. Dock water is the rarely unutilized public space scattered along Thames that can also act as heat sink. Implementation of energy infrastructure that reorganizes local consumption pattern can foster sustainable urban expansion at strategic locations along the Thames river. New technologies such as molten salt heating system and traditional technologies such as steam power/mechanics will be reassessed in contemporary urban conditions.


In relation to local industry, refinery and distillation processes can benefit from the aforementioned resources. This seeks to revive East London’s strategic role in light industry in contemporary context. An archipelago typology suggests a new lifestyle that utilizes dock water with social and cultural agenda.


Heat transfer and energy consumption pattern become critical instruments forming community in the future. New community decides ways to utilize and bridge the gap on the temperature scale. Investment, employment and education opportunities will benefit local dockland residents while remaining coherent to their identity. Since investment behaviour and  phasing strategies are decisive in urban expansion, the infrastructure should devise modular construction system that allow the inhabited community to expand or shrink in an organic manner. 3


[Anticipated outcome]


The result constitutes pattern changes in local energy consumption and production. Surplus heat energy enables new programs to inhabit on site as the community develops while reduce operation of primary energy power plants. This in turn reduces pollution generated from traditional power production system and contributes to a cleaner Thames waterfront. The investigation seek to provide solutions for cities that rely heavily on port trading activities.




1. The utilisation of secondary heat sources via district heating networks has the potential to be viable at scale. The estimated maximum quantity of secondary heat that could be effectively used (24,900 GWh/year) represents approximately 24% of London’s current heat and power demand. This suggests by utilizing secondary energy alone would exceed the Mayor’s overall strategic target of supplying 25% of the heat and power used in London from localized, decentralized energy systems.


2. Private interests is often seen as a detrimental factor for the undesirable urban conditions we have in modern days (CIAM’s Charter of Athens). The most valuable discussion about the RDM Rotterdam Campus is its ability to infuse and reconcile public interests and private interests.  It is therefore hypothesized that programmatic arrangement can be crucial to urban development as it sets up the agenda and positions of various economic forces in the first place.


3. From my initial investigation departing from purely energy consumption/ production perspectives, infrastructure based on regenerating energies tend to form a segregated part of the city; while infrastructure based on adaptive re-use that inject social programmes can bring in human resources, which ultimately seek a spectrum of environmental solutions.
