6 Electrical GSHP Annual hot water + heating requirement: 3,000kWh + 4,760kWh = 7,760kWh 3.5kW electrical ground source heat pump Calorex, UK-based firm --> low embodied energy COP 7 C to 35 C : 5.25 COP 7 C to 55 C : 4.20 Quiet: 1m 6

7 Battery Sizing According to different case studies (Brighton,UK & Yukon,USA): 5 days of autonomy : storage 100 kwh 5 batteries Raylite 48V 600Ah 7000 each year life expectancy 7

8 Battery Sizing Example of sizing curve and design space for different reliability levels 8

9 Battery Sizing Hourly mean load variations on a typical day (for a remote village in Maharashtra, India) Diurnal variation of hourly mean wind speed for representative days in each season at 10 m above ground level 9

10 Ventilation with heat recovery 10

11 Determination of our Ventilation Needs Properties: 2 floors Surface : 13.5 x 8 Air Change per hour: 0.3 Good Airtightness with effective insulation => Limit the warm air leaking (13.5 x 3.28) ft. x (8 x 3.28) ft = 1,162 ft square 1,162 sq. ft. x (2.5 x 3.28) ft. high x 2 = 19,055 cu. ft. 19,055 cu. ft. x 0.3 ACH = 5,716 cubic feet per hour = 95.3 cubic feet per minute = (95.3 / 2.119) L/s = 45 L/s 11

12 Choice: Broukvent 1350Cl ( United Kingdom) Different modes: Night/Away Mode ECO Mode Mode normal Mode Week-end Multi function autoboost 12

13 Systems and controls The Digital Intelligent Control System utilizes an ECO mode to ensure that precisely the right amount of ventilation provided. Thermostat Humidistat Air quality sensor 15,30,45 and 60min manual boost options and 1 to 60min autoboost overrun adjustment. Internal vacuumable filters, «Easychange G4» Additionnal filters for wet areas ( kitchen Bathroom, laundry) 13

14 Life Cycle Analysis It consumes CO2 during its life and it is a local product, so the CO2 produced is negative Natural material and the reaction to make it is exothermic 14

15 Life Cycle Analysis Common thermal insulator with good thermal performance 15

16 Life Cycle Analysis Other appliances such as: The wind turbine (life expectancy of 25 years) Greenhouse gases The turbine will payback its embodied energy and carbon within 18 months The Ground source Heat Pump which consumes 1500kgCO2/year 16
