Abstract:
In this research, the application of biogas for passive country housing in Egypt has been simulated dynamically to calculate the annual energy savings as well as CO2 emissions' reduction. The country house prototype applies vernacular design elements as part of a new urban development project southern Cairo. Various envelope materials and thicknesses have been applied prior to simulating this housing typology with 2m3 biogas unit operated through the supply of farm animal and agriculture residuals. Climate change scenarios simulations in 2020, 2050 and 2080 using Design Builder showed remarkable energy savings, cost and CO2 emissions reductions in preference to using biogas with high resistant building envelope.
