Indoor heating and wall insulation systems are vital parts in building energy saving designs. Based on the analysis of impact factors related to the energy saving design of indoor heating and wall insulation systems, this study adapted the variation of room temperature as the performance index of energy saving design. A calculation model of energy saving design was established based on heat balance theory. Using the proposed model, the variation curves of room temperature with time and the sensitivity of room temperature on various technical factors were analysed incorporating different insulating materials, thicknesses of insulation layer as well as different temperature and flow rate of hot water in the boilers. Finally, it is proposed that the design solution of energy saving system should consider and assess the technical, economic and environmental factors from the perspective of project life cycle. Results from the study showed that the simulation of the proposed model was clear and easily adaptable. The proposed model is capable of providing abundant simulated data for design personnel to predict the performance of the design and optimise the parameters. The findings in the study provided theoretical background and routine for the determination of parameters and design for indoor heating and wall insulation systems for developing and designing companies.
