Case Study – Urban Splash @ New Islington
  

• 12 Hectare Site 
• Part of Millenium Housing Sites 
• 1970’s Housing Estate dubbed the Worst Estate in Manchester 
• Assests retatined – 
• Canal Network 
• Community Spirit 
• Collaborative Workshops offered re-housing options to residents 
• Rebranding of estate 
• Will Alsop Masterplan, including “the Chips” 
• Mixed Use, including 
• 1700 new homes 
• Variety of Parks – Community Park, Wildlife Island, Orchard, Boardwalk, Beach 
• Revival of Waterway 
• Primary School 
• Primary Care Centre 
• Small Scale Retail 
• 180units/hectare 
• All dwellings to achieve Eco-Homes Excellent 
• Maximise use of natural sunlight 
• Use of low embodied energy materials throughout 
• Combined Heat and Power, future-proofed for bio-fuels 
• Jobs created for local people within the construction phase
    

Things you might forget, or things you might not know… 

• Integrate design at an early stage – ideally stage A/B, rather than at Stage C/D – consulting Energy Engineers / assessors. Check for Policy changes if the project has been on hold for a while.
    
• Recent UK Policy changes include PPS1 Addendum –
              Demonstrate how building regulations to be met at planning stage
    
• Passive Design – 
• Use the sun’s energy to reduce winter heating requirement 
• Orientate main façade within 30degrees of south 
• Avoid overshadowing 
• Utilise thermal mass to store heat 
• Minimise glazing to north façade 
• Add a glazed winter garden to south façade 
• Incorporating 2-3% Carbon Dioxide emission savings may reduce the “renewables” target – spray taps, smaller baths, energy efficient applicances + lights
• Remember to design in CHP Spaces into 1st phase of phased construction
  Use Thermal Analysis at scheme design stage to highlight potential overheating + design out prior to planning consent
    
• Check Planning Policy for correct wording –
  If 10% CO2 saving is required, target electrical – 3.5m2 Solar Thermal panels should achieve target saving
  If 10% Energy saving is required, target Gas – 2.2m2 Solar Thermal panels should achieve target saving

• Pilkington “Optitherm” glazing controls heat loss and solar gain  
• “Ecoplay” grey water systems will treat + recycle grey water for use in WCs  
• “Dupont Energain” is a gypsum/paraffin Wax sealed board, which absorbs heat in lightweight construction by altering its state (effectively melts and solidifies) in hot temperatures. More info
