Case Study: Resilient city design Flashcards
Urban Environments- Resilient City Design
What is the name of the case study?
BedZed
Where is the site?
Wallington, England
What is BedZed?
A living compound with
- office spaces
- mixed housing
- social spaces
Which aims to release zero carbon emissions and attempts to live self-sufficiently
How was it constructed sustainably?
Built using recycled and 15% reclaimed materials.
More than half of the materials were sourced from a 35-mile radius
When was it constructed?
2002
In what ways does the house minimize energy input
Less energy/heat loss: The walls are incredibly thick and consist of 1/3 insulation
- South-facing domes are passively heated through sunlight
- North-facing domes rely on the biomass boiler (sustainably sourced woodchips)(CHP Plant)
- solar panels at the top of all roofs
How does BedZed minimize carbon emissions via transport?
- Offices at the site
- Shared Vegetable gardens
- Minimal Cars (electric) at site (powered sustainably)
Strategies to make this project resilient and sustainable for people
Improved sense of community:
- shared garden
- shared offices
- *people living there said they know 20 neighbors personally, which is much more than that of London/ any city
How expensive was BedZed?
$17 Million
Evaluate how this project is not realistic to other countries/reigons
water accessibility in England is easy because it rains so much
- this is unrealistic for areas suffering from drought
$17 Million was the cost
- not reasonable for low-income countries
How is water filtered and harvested?
Harvested: Zisternes, No concrete used on the floor, percolative floor
filtered: Through reed beds that filter the water
Energy facts
90% less energy demands
45% less energy use
no AC needed: holes for air filtering
What are the issues of BedZed?
- contaminated water
- not enough privacy
- underperforming solar energy
- the CHP plant(creating the energy) is too small for its demand, doesn’t work well for longer periods of time
