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.

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%

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

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

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

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%

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

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

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

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

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 %

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
