Description

. Energy demand for heating and hot water: Energy demand for heating and domestic hot water of a hypothetical residential building with different thermal insulation conditions. .Sizing the heating and hot water system: Sizing different design options with complementary boiler and accumulator tank considering daily and hourly temperature fluctuations. .Fuel supply costs: (i) Alternative fuel requirements based on the net calorific value of each fuel and energy demand requirements. (ii) Estimation of wood chips supply costs. .Economic evaluation of system alternatives. (i) Calculation of investment costs for the heating and hot water alternative systems, the exterior insulation and finish system (EIFS) and the pipe installation for the heating network, (ii) Calculation of operation costs of the heating and hot water systems with different thermal insulation conditions, (iii) Determination of the equivalent annual costs per dwelling for one to five buildings in a network including thermal insulation improvements . (iv) Net present value of firewood boiler replacement by woodchips and by liquified petrol gas boilers.
