2. Aim of project
Is to design 3 housing types which will form a 20 dwelling net zero carbon community, located in rural Ayrshire
Designed to Code Level 5 or better

7. What is the Code for Sustainable Homes
A measure of the ‘whole home’ as a complete package
Consists of 9 categories
Energy and CO2 emissions
Pollution
Water
Materials
Management
Health and well-being
Surface water run-off
Waste management
Ecology
Credits are awarded if individual targets are achieved.
Aim for today: to go through each of the nine categories and show how our community has achieved a code level 5.

8. Code 5 Materials Use of environmentally impact materials
Straw Bales, timber , Sheep’s wool, timber framed windows
Low in embodied energy
Source of materials
Responsibly sourced e.g. Timber certified
Locally sourced from site
Paved surfaces from recycled and sustainable sources
Credits: 21/24  6.3%

9. Code 5 Water Internal water usage: External water usage:
Code level 5 & 6 total
<80 litre/person/day
External water usage:
Rainwater collection
Washing car & garden, etc
Grey water collection
Washing dishes, washing machine, etc

10. Code 5 Phytodepuration System Advantages to the system
Natural treatment of waste water due to plants
Advantages to the system
Simplicity
Cost effective
Efficiency
Reliability

11. Code 5 Surface water run-off Bio-filtration
Grey water and rainwater harvesting
Site out of flood risks
4 points  2.2 %

12. Code 5
Waste Management
Storage of non recyclable waste and recyclable waste provided by local authority and local authority collection
Construction Site Waste management plan
6 points  5.4%

13. Code 5 Pollution Low GWP of insulants : CO2 No NOx emission
4 points  2.8 %

14. Code 5 Management Home user guide provided
Considerate Constructor Scheme
Responsibly sourced timber and report and targeting for water consumption
6 points  6.6 %

15. Code 5 Health and well being Day lighting
Detached houses (sound insulation)
Garden (private space)
Community car park
Disabled access
12 points 14 %

16. Code 5
Energy and CO2
PV, Solar Thermal, and GSHP (with seasonal storage)
Timber frame with straw bales, MVHR (air tight and good HLP)
Day lighting and efficient lamps
Drying space
A++ appliances
Study room

17. Code 5 Ecology Low ecological value of site (Pit bing reclaimed land)
Consultation of an ecologist to improve the ecological value of site after constructions of dwellings
6 points  8 %

18. Conclusion Total credits achieved – 85.6%
Code 5 – 84%
Our community has been effectively designed to Code Level 5 for Code for Sustainable Homes
Further work to undertake in order to achieve Code Level 6:
Provide external lighting
Secure cycle storage
Provide safety and security for the community
