The Passivhaus Skyscraper
2012, University of Nottingham, David Nicholson-Cole & Philip Oldfield

Passivhaus is a design concept where thermal comfort is achieved to a maximum extent through passive measures – super-insulation, heat recovery, passive use of solar energy and internal heat sources. Such buildings benefit from comfortable internal environments and significantly reduced energy needs. Tens of thousands of Passivhaus buildings have been constructed globally in the last 20 years. In lieu of  these advantages, it seems strange that there have been very few attempts to design a Passivhaus Skyscraper, especially considering the reputation of high-rise as being inherently "anti-environmental."

Building on the
2011 studio of the same title, this studio challenges students to design a sustainable tall building in the Elephant & Castle district of London incorporating Passivhaus design principles. However, the brief goes far beyond this, tasking students to marry these environmental ideas with innovative and exciting tall building forms and functions, designing architecture that creates communities rather than isolates at height and demonstrates how the tall building can make a positive impact on the city in terms of both environmental and social performance.


Flood Plain Tower Passive Tri-scraper
Deepika Singhal and Rishika Shroff
 
The master plan of this scheme is comprised of three slender towers, arranged to maximise density, minimize over-shading on one another and the existing park at the centre of the site, and provide a skyline transition between the westerly low-rise communities and the high-rise buildings to the east.

Filtered Light Tower   Healing High-Rise
Noura Ghabra, Jink Huang, and Rong Xu
 
This project aims to tackle both environmental and social sustainability through the design of a tall building that meets Passivhaus performance criteria while responding to the human needs of health and wellbeing. It accommodates a mix of functions. The design agenda is embraced within the building through three states relax, nurture and heal.

Green Core
Alejandro Carrasco and Veronica Oyarzun
 
The primary aim of the Green Core is to create a tall building that celebrates its multiple functions rather than hiding them away in a singular monotonous form, while also responding to the unique environmental needs of each. The result is a tower housing office, hotel and residential spaces, with each shifted around a central core to meet their unique requirements.

Stacked Courtyards   Flexiscrape
Sayali Ghorpade, Pelin Gurkan, and Nirav Khandwala
 
One of the primary advantages of suburban low-rise living is the ability for occupants to expand or adapt their dwelling as their situation changes. The Flexiscraper aims to challenge this scenario, creating a tall building that is characterised by adaptability and extendibility, being suitable for growing and changing family requirements.

Hydroponic High-Rise
Sian Hodgson
 
The Hydroponic High-Rise aims to combine vertical farming with passivhaus social-housing. An existing client group within Elephant and Castle, the "Mobile Gardeners," are currently using land within the neighboring Heygate Estate, but this is soon to be lost to redevelopment. The Hydroponic High-Rise will therefore create a new space for this group to inhabit as well as other members of the community.

Green Roof City   Solar Steps
Wezha Baiz and Udayan Jain
 
London, and Elephant & Castle, has gained a significant number of temporary immigrants in recent decades – 12% of the population is made up of migrants who visit the UK for a period of only two to four years. Solar Steps aims to be a social destination for migrants, providing medium term accommodation for those new to the UK, including international students, refugees, and those who come to work temporarily.
