Low Energy Building Design 2010

1. Low Energy Building Design 2010 Presentation 3 TEAM ZERO Arnaud Gibert Bintou Ouedraogo Danny Tang Naeema Hafeez Paul Dupuy

2. Aim • 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 • To be an exemplar of sustainable, low energy design for the future developments

3. 2 Bedroom

4. 3 Bedrooms

5. 4 Bedrooms

6. Materials • Concrete Foundation • 25% fly ash replacing Portland cement- 25% reduction in the embodied energy • Timber Frame Construction • Source: Approx. 50-55 miles from the site • Straw Bale with concrete stucco finish • Straw bale used as an infill material • Source: approx 55-60 miles from site • Cost of bales: approx. £1.50/ bale (pick up yourself) • OR £2.50-£3.50 (delivered, costs depends where and how far) • Triple Glazing windows with multiple low emissivity coatings and a xenon fill with timber frame • High performance glazing with timber frames help keep the heat trapped.

7. Embodied Energy

8. Embodied Energy • Embodied energy is a significant contribution to Scotland’s CO2 emissions • Conclusion • Embodied energy of a home varies according to its size, type of construction, building materials, where the building materials come from, and where the home is built. • To obtain a low embodied energy • Using lightweight construction, this is why timber frame was used for our project • Locally sourced materials, in this case straw bales, where such little energy is required to extract, process and manufacture this material.

18. Waste Water Management • BiotankbyBiokube • Certified and tested to European Standard EN 12566 • Installing this systems is low risk, high gain.  • Biokube guarantee that their system will perform as what has been stated by them. • The Biokube system is maintained and serviced by the supplier • 5 year warranty for part • Water can be used for irrigation purposes due to more efficient treatment (less than 10mg/l BOD : 15 mg/l Suspended Solids : 5 mg/l Ammonia).

19. BioKube Mars • Dimensions for BioKube Mars are Ø 200 cm., Height 150 cm. and Weight 320 kg. • Very compact in size for a system designed to clean wastewater up to 30 people. • The Mars system comes in a range of treatment capacities from 15PE to 30PE. • Annual Maintenance Cost - £170 • Cost to buy £7000- £8000 per tank

21. Plan of work • Gather all information • Finalise each component • Come up with a conclusion • Website
