Energy Consumption Analysis of a New Rural Green Building
Abstract:
In order to meet farmers’ energy demands of gas, domestic hot water and winter heating with renewable energy in rural areas, according to farmers’ living habits in winter, a 30m2 insulated rural green building made of brick and concrete, was developed to integrate with thermostatic digester heated by solar energy and low-temperature radiant bed. Energy expenditure and thermal economy of the green building were studied at different winter ambient temperature subsequently. The results show that the consumer’s energy demands of gas, hot water and winter heating can be met in the green building even in winter. When the outdoor temperature is -20°C, the indoor’s is higher than 15°C. Compared with traditional rural buildings made of brick and concrete, the new one saves 2.8 tons of standard coal and RMB¥3275 every year and the payback period of investment of the enforced cost is 3.9 years.
