1. The Plant Riverside Park, Bristol

The Plant:

Year 4 Project 2, [51.462224N, -2.578710E] With the impacts of climate change becoming more apparent every year, it is now crucial that global carbon emissions are reduced to a level which does not cause the planet irreversible harm. One of the most promising areas for CO2 reductions is in the generation of energy for use in buildings, which currently accounts for around 34% of the UK’s annual carbon footprint.

District heating and electricity from combined heat and power energy centres has the potential to reduce emissions of connected building by around 30%.

The construction of these centres presents a unique opportunity to reevaluate our relationship with energy.

Instead of banishing them to lifeless metal boxes in the outskirts, could we harness the educational potential of such buildings and bring them into the heart of our towns and cities? Framing the CHP process like an exhibit in a museum, The Plant aims to prove that this is possible, bringing a community hub and an energy centre together under one roof to passively educate visitors about clean energy as they inhabit the building.

Site Response Key Site Decisions

1.

Retain existing treeline as buffer between Riverside Park and the M32/Newfoundland Way

2.

Reconnect St Pauls and St Judes with wider, safer and more direct access across the M32, Riverside Park and the River Frome.

3.

Widen and improve the path which follows the River Frome through the park to encourage more people to walk and cycle into the city rather than driving.

4.

Locate all development towards the city centre end of the site, with the scale of the building decreasing towards the park to help it sit more comfortably within the open space.

3

5.

Remove certain paths and trees to provide a large, uninterrupted green space within Riverside Park for play and recreation, as well as for events such as markets and festivals.

6.

Access to the community canteen at the busy intersection of the primary circulation routes, with it positioned away from the other community facilities to preserve functionality during large events in the hall.

7.

Access to the hall and classroom spaces from the path connecting the two communities who will use the building.

8.

Riverside Yard to act as a vibrant communal urban space serving both the youth centre and the Plant, suitable for ball games, pop up markets and group games.

9.

Riverside Walk to provide a peaceful green route into the city centre, with the River Frome landscaped and planted to encourage wildlife.

10. Riverside Piazza to serve as the main hive of activity around the building, with activities from the main hall spilling out and into the park.

2. Algae-Culture Brabazon, Bristol

Algae-Culture:

Year 4 Project 1, [51.518494N, -2.571795E] Located at the entry point of the emerging Brabazon masterplan in Bristol, Algae-Culture is an new kind of exhibition centre for a greener society. With a form sculpted deliberately to gather maximum sunlight, the building’s algae-covered roof promotes a fast growing, underutilised food source which has the potential to drastically reduce the UK’s carbon footprint.

In its first lifetime the building will serve as a centre for the developing community in Filton, hosting lectures and exhibitions for the new low carbon homes and infrastructure in the area. Once the masterplan is complete, the building will transform into a centre for low emission aerospace research, promoting a greener future for Bristol’s historic aerospace industry.

60% of the area of the UK is used to grow animal feed crops. Millions of hectares could be freed up if algae was adopted as an alternative on a nationwide scale.

Space for Sustainability 4.

More space for tree planting, rewilding and other habitat restoration to absorb CO2 and enhance biodiversity across the country.

3. Coalesce Campo Santi Apostoli, Venice

Coalesce:

Year 3 Project 2, [45.440251N, 12.336659E] A fire damaged group of buildings around Campo Santi Apostoli in Venice needed sensitive reconstruction to restore the historic community hub. All internal structure had been destroyed though some of the external stone walls remained intact.

The previously successful tavern and ice cream parlour were to be reinstated on the ground floor alongside a new gondola repair workshop. The upper floors needed to contain two new medical services and a mixture of 1, 2 and 3 bed apartments.
