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

targeting for water consumption

6 points 6.6 %

Code 5Health and well being

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
