Conclusions
Shanghai and New Orleans have a surprisingly similar climate. Many of the design principles of the New Orleans climate are applicable to the design of the Yu House. The climate information of Somerset, however, is helpful for our design, as Shanghai’s climate is colder during the winter months than New Orleans.

2 Exterior Design Options - a Gable prototype that includes sunscreens- a Garden prototype that includes a roof deck, - variations to the exterior fit-out, including PV panels, sunscreens, storage, and rainwater harvesting allow the house to accommodate a range of homeowners
Design for Flexibility & Customization- floor plans consolidate “dry” and “wet” spaces into zones. - linear plumbing systems into linear clusters- ‘wet’ modules can be fabricated off-site
On-site vs. Off-Site Fabrication- The proposed design anticipates a transition from stick-built construction in the first generation to off-site fabricated subassemblies in later generations.

Brownfield SIte
Site ContaminationContaminated soil from the site’s former life as a river wharf is dis-posed of below the raised buildings and under paved areas. Planting which combats contamination natu-rally is used within the landscaping.
Wildlife habitat Badgers present on the existing site are incorporated into the de-velopment with the creation of new setts in a quiet corner of the site.
Site ParkingCar parking is limited to one space per home to encourage use of pub-lic transport and cycling

Sun spaces on Southern North Wing They are positioned and designed to improve the environmental performance of the houses.1. Act as a buffer between inside and outControlled by doors, vents and louvres according to the weather and if used correctly will reduce the heatingrequirement for the houses2. Use the warmth of the sun to preheat As well as the energy benefits, the sunspaces will also be a bright, sunny environment for occupants ventilation to the adjacent living spaces3. Create a large draught lobby to the garden on the south sideFor much of the year they can be considered as an extension of the living space, being large enough to accommodate chairs and a table

Maximum Daylight
High efficiency double-glazed, argon-filled timber frame windows are used. Unlike many low energy developments which use small windows, openings are deliberately large for maximum daylight and to engage with the site.

Light Timber Structure Construction 1. Reduce Thermal BridgingThe East Wing uses lightweight timber frame construction with I-section timber sections for reduced thermal bridges and maximum thermal and material efficiency.
2. Roof Design for Solar PanelsThe roofscape is designed to provide a south facing base for the incorporation of photovoltaic panels despite the terrace’s east-west orientation.
3. Best Orientation of Living SpacesLiving spaces in all but two of the flats are located within the roof space to exploit the best daylight and views. Bedrooms are located on the first floor while integral garages and home offices make up the entrance floor.

1. Reclaimed brick usageImperial sized bricks from a recently demolished house in local Bridgwater were used. Lime mortar ensures that they can be used again at the end of the building’s life.
2. Efficient Insulation Use-Both buildings exceed thermal efficiencies required by current building regulations, with some parts of the building envelope incorporating 350mm depth of insulation. -Approximately half the insulation used is made from recycled newspaper (celluose).
3. Timber Construction Efficiency -FSC and PEFC timber is used throughout. -Cedar boarding which forms the main cladding material is sourced from South Wales. -Wood chip paths in the communal landscape are formed using branches pruned from trees on the site. 4. Avoidance to use PVCApart from soil and vent pipes and rainwater tank connections, PVC is not used in the development. Ply is used in lieu of MDF and natural paints, which contain no petroleum solvents, vinyl, or other toxic components, are used.

1. Water Heated by Solar Power Solar thermal panels mounted on the south façade will use the sun to provide hot water.
2. Sustainable Drainage Strategy (SUDS)-A swale collects surface water from the road areas and distributes it into a drainage ditch.-A possible future holding pond in the central landscaped area is proposed.
3. Toilets Flushed by RainwaterIn the North Wing, rainwater from the roofs is collected in storage tanks mounted above the porches and used for dual-flush toilets. Rainwater butts in the East Wing collect water for garden use.

How can a house design in Lousiana and the UK help us in the design of the Yu House?Chassis design differs from Yu House, however as the Yu House is going to be moved, there are opportunities of learning from this strategy
Climate conditions of New Orleans are similar to those of Shang-hai
Prefabrication offers a unique perspective of construction tech-nologies
Brownfield site has a similar relationship with the Yu House’s current location
Climate coinditions aid in the design for the wintertime
Due to the climate conditions, visual line of sight was enhanced by the need for solar infiltration - enhances views to nature

How can a house design in Lousiana and the UK help us in the design of the Yu House?The house divided into ‘wet’ and ‘dry’ modular zones is an inter-esting lesson for design
This house offers a modern interpretation of the traditional New Orleans housing vernacular.
Water:
Use of natural vernacular materials both enhances the aesthetic product and energy efficiency
Use of reclaimed brick and other local materials reminds us of the challenge of the Yu House.
Hydrolic systems have been integrated with other systems - this proves to be a successful solution to enhance the surrounding landscape
