Aim of projectIs 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

What is the Code for Sustainable HomesA measure of the ‘whole home’ as a complete packageConsists of 9 categories
Energy and CO2 emissionsPollutionWater MaterialsManagementHealth and well-beingSurface water run-offWaste managementEcology
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.
Code 5Materials
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%
Code 5Water
Internal 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
Code 5Phytodepuration System
Natural treatment of waste water due to plants
Advantages to the system Simplicity Cost effective Efficiency Reliability
Code 5Surface water run-off
Bio-filtration Grey water and rainwater harvestingSite out of flood risks
4 points 2.2 %
Code 5Waste 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%
Code 5Pollution
Low GWP of insulants : CO2No NOx emission
4 points 2.8 %
Code 5Management
Home user guide providedConsiderate Constructor SchemeResponsibly sourced timber and report and
targeting for water consumption
6 points 6.6 %
Code 5Health and well being
Day lightingDetached houses (sound insulation)Garden (private space)Community car parkDisabled access
12 points 14 %
Code 5Energy 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 lampsDrying spaceA++ appliancesStudy room
Code 5Ecology
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 %
ConclusionTotal 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 lightingSecure cycle storageProvide safety and security for the community
