An Approach to Sustainability

• Scheme Attributes
• Site assessment - natural history, drainage,
  transport links, solar aspect etc
• How can design help the scheme?
• Natural Features topography, flora, fauna
• Contactor and Materials Local low transport
  carbon emissions
• Services and facilities

7
Aspirations Objectives

• Sustainability- Exemplar schemes- but not just a
  Demonstration projects
• Positive impact on local environment
• Ecohomes Excellent incorporating Energy
  Efficient Homes and Renewable Energy
• Moving towards Code for Sustainable Home level 3
  and better.
• Aspiring to Carbon Neutrality

8
Renewables Options

• Biomass
• CHP
• Ground Source Heat Pump
• Micro Wind- Domestic and Communal

9
Renewables- pros cons
10
The Lowdown

• Energy Efficiency via Design Materials
• Minimal impact from Materials Methods
• Passive benefits- aspect and Solar Gain
• Water Conservation/ drainage strategy

11
Renewables Options

• PV
• Solar Thermal Water Heating

12

• Partnership with Kirklees Environment Unit
• 113kW of Photovoltaic installations
• 63 Solar Thermal Installations
• The highest concentration of domestic solar
  technology anywhere in the UK.

Effect in Use
16
Ecohomes Elements

• Ecohomes Rating Excellent- Key points
• Energy CO2-lt 25kg/m2/yr
• Fabric 27 improvement on Building Regs
• Transport- Bus routes and Cycle storage
• Pollution- non-polluting materials, Low NOx
  boilers, 50 reduction in Surface water run off,
  Solar Thermal heating
• Materials- 100 FSC timber in building elements
  facing materials
• Water Use- reduced to 44l per person per day
• Ecological Enhancement- Ecological Assessment

17
Concrete- A Compromise

• Structherm Fastbuild System
• OSM
• Local Manufacturer
• Pulverised Fuel Ash
• Thermal Mass
• Recyclable
• Sound insulation
• High Energy to manufacture
• Additional cost

18
Ecohomes- The Cost?
Ecohomes Rating Excellent- Key points Energy
Around 10 of basic building elements for Timber
frame/ Structherm 200,000 Fabric Around
10,000 for added insulation Transport- Cycle
storage- around 10,000 for increased external
storage Pollution- Low NOx boilers, around 100
per property for increased spec boilers. Around
200,000 for water attenuation scheme. 50
reduction in Surface water run off. Zero Carbon
Energy- Solar Thermal heating around 2,350 per
property. PV around 5,000 per kW Materials- No
extra cost Water Use- No extra cost Ecological
Enhancement- Ecological Assessment- around
1,500
19
Ecohomes The Cost?

• Over 79 properties from Good to Very Good/
  Excellent
• around 11,000 per property
• Without PV- around 6,000 per property.

20
What Next?

• Replacement for Ecohomes
• Code 3 between Very Good/ Excellent
• Mandatory requirements- CO2 and water saving
• Cost? 5,000-15,000
