5 Low Energy House \ PassivHaus Electricity Space heating Water heating Energy Demand Mathieu Bicego

6 Low Energy House \ PassivHaus Requirements Heating Energy < 15 kwh/m²/year Total use of primary energy < 120 kwh/m²/year The building must not leak more air than 0.6 times the house volume per hour. Mechanical heat recovery ventilation => Heat transfer, Airtightness and comfort

7 Electricity Good family behavior and energy-saving electronic devices =>The daily electricity consumption of the family could be around 1500 Wh/day. Space Heating Considering a monthly average temperature of 9 C and a warmed surface of 700m² ( house on two floors ) we can define a monthly space heating demand of 3 MWh. Hot sanitary water Admitting the temperature of cold water is 10 C ( rain water, sea water) and the domestic temperature 45 C we can approximate a demand of 350 KWh monthly.

10 Geothermal

11 Solar

12 Storage Hydrogen : + zero carbon/ can be produced from any primary source - low energy density per volume (even when highly compressed) compared to traditional hydrocarbon fuels. electrolytic generation from water are more efficient.

17 Shape Materials Sustainable Design Efficiency Design Design Aurelie Charton and Mathieu Bicego

18 Shape Different studies show that a subsequent design follows a classic rectangular shape with the longest side facing south for op7mum solar gain. Solar thermal panels => sloped roof with an inclinaison of 35 for a best efficiency

19 Materials PassivHaus insulation standard : U-Value must not exceed : W/m 2 /K for walls W/m 2 /K for windows Local materials if possible (low embodied energy)

20 Materials insulation Thermal and environmental performance of insulation material Hempcrete HEMPCRETE Cellulose Wood wool Sheeps wool Rock mineral wool Cork glass mineral wool CELLULOSE Aerogel Embodied energy in MJ/kg thickness required to meet passiv Haus standard (cm)

21 Materials insulation Straw bales -Infill material for timber framed buildings -Very low level of embodied energy -Derived from a renewable source -Have very high insulations values : Thermal conductivity of W/mK1. (34cm-54cm to meet PassivHaus standards)

22 Materials External Walls Timber frame external wall finishes 1.Rain screen of durable timber from sustainable source 2.Lime sand render 3.Fibre cement sheet rain screen

23 Materials Internal Walls 1.Timber frame + insulation 2.Hemp blocks 3.Sand lime blocks HEMP BLOCKS Internal walls finishes 1.Local timber finish 2.Lime or clay plaster 3.plasterboard 4.plastic boards TIMBER FINISH SAND LIME BLOCKS LIME PLASTER

24 Materials Local Wood UK timber : 0.52 GJ per ton Imported timber : 7.1 GJ per ton European Oak (Variable availability in UK but durable) We s t e r n R e d c e d a r (Regular availability in UK but moderately durable)

25 Sustainable Design Meeting Community Needs Working with the Highland Landscape & environment Providing Access for All Healthy Buildings Minimizing Energy Required in Construction Use of Sustainably Produced Construction Materials Minimizing Energy Use in Building Operation Minimizing & Managing Waste Sustainably

26 Efficiency design Below the tips should assist the project in achieving an optimum energy efficiency rating: Orientation, External and internal walls, Window, Ceiling, Eaves, Roof, Colour, Floor, Entry, Stairwell, Skylights, Draught Control, Ventilation, Landscaping

27 Efficiency design orientation 'Living Zone' - lounge, family, dining, kitchen - with a north orientation. 'Bedroom Zone' to the south. 'Unconditioned Zone' - bathroom, shower, laundry - to west (or east). Carports/garages to east (or west).

28 Efficiency design orientation Colour -'Light' coloured external walls and roofs lower summer cooling energy requirements. -'Dark' coloured walls and roofs reduce heating energy requirements in winter. Roof insulation selection consider the thermal needs of the building and adapt to the energy system used Ventilation -Positioning of windows: natural crossventilation during summer. -Ceiling fans,mechanical ventilation
