PROJECT DESCRIPTION - BRIEF• Medium sized housing development,
comprising of new sustainable and innovative ideas.
• Semi-rural locale, green land with a blank canvas.
• A number of aspects of this brief changed throughout its development.
• This presentation will explain and express the rationale behind its conception.
RATIONALE
• Sustainable design on a large scale• Community integration• Self-sustaining• Attractive• Minimize materials, maximize impact• Suitable for all• Flagship community
CONCEPT HOUSE DESIGNKey Factors• Solid & Fast Construction• Energy Efficient • Flexible Design • Make the most of the location• Meet high standards• Fit for purpose• Life time home
CONCEPT NURSERY DESIGNKey Factors• Fit for purpose• Meet Users needs• Flexible Design • Meet Building regulations• Maximizing learning for students• Aesthetically pleasing
CONCEPT COMMUNITY CENTRE DESIGNKey Factors• Solid & Fast Construction• Energy Efficient • Flexible Design • Make the most of the location• Meet high standards• Fit for purpose
ICF – INSULATED CONCRETE FORMWORK• Quick, fast, solid and long lasting
construction• Lightweight, Compact transportation• Minimal waste on site• Excellent thermal properties and no
thermal bridges• Manufactured from Recycled material • BRE green guide ratings: A+• ICF Southern – Distributors located in
Storrington, West sussex
CHP – COMBINED HEAT AND POWER
• Energy Efficient – 90%• Cogeneration as standard with
trigeneration abilities.• Future for biomass incorporation• Can run on multiple sources of fuel• A++ Energy rating• Meets BREEAM standards• Bosch – Warndon, Worcester, WR4
9SW
TERMODECK & BISON HOLLOWCORE
• Solid, prefabricated planks• Large uninterrupted spans• Sound resilient• Multiple uses – Cable runs, HVAC
incorporation• Recycled aggregates• Excellent thermal mass for hot/cold
storage• Flexible design
MARLEY ETERNIT ASHDOWNE CLAY PLAIN TILES
• Traditional handcrafted • BRE Green Guide A+• Responsibly sourced• 60 year life span• Can be recycled into aggregates or
inert bulk fill• Multitude of different fixings and styles• Attractive mellow design
VMZINC STANDING SEAM ROOF
• BRE Green Guide A+• Responsibly sourced• 100 year life span• 100% recyclable • Less embodied energy• Low maintenance
RAINWATER HARVESTING• Large surface areas throughout the
site• Reduced water consumption by 50% • One connected system • Multiple uses – Allotments, flushing
cisterns, open space maintenance • Ability to convert to potable water• Reduced flooding risk with soakaways
and underground storage
KINGSPAN KLARGESTER • Independent self contained system• Low maintenance and running costs• Compact all in one system• Waste water can be fed to SuDs pond
through the reed bed for further filtration
• Gamma septic tank – Sludge can be used in many applications such as fertilization or for producing methane
SITE MATERIALS
• Ronadeck Resin Bound Surfacing• SuDs compliant• Resin from a botanic source• Low maintenance• Suitable for traffic areas
• Permeable Block paving – Forterra• Aquaflow & Aquaslab• Combined with soakaways • Helps break up the roadway
SUDS – SUSTAINABLE URBAN DRAINAGE SYSTEMS
• SuDS• Flood risk management• Water quality management• Amenity and biodiversity• Water resources• Community• Recreational• Educational
FUTURE ADAPTABILITY The Development has been designed with adaptability in mind
• Wattway• Solar paving that can be
implemented into existing roadways• 20m2 enough for single house
• PV panels or Evacuated tubes• Each building has the ability to be
equipped with these, without the roof structure being affected
FAILURES AND SUCCESSES• Successes
• Achieved end goal• Successful system integration• Realistic housing design• Sustainable• Community integration
• Failures• Time management• Lack in design renders• Site implementation into BIM• Too ambitious• Site analysis
