Research on the technology of low-carbon community for the areas where it´s hot in summer and cool in winter —Taking Changsha, Hunan as an example

This article carefully explores the technological approaches for building low-carbon community based on the climate condition of hot in summer and cold in winter with no changing people´s life habit as the premise. (1) Setting some natural ventilation corridors to ensure the better hot physical environment outdoor in summer. It may reduce the hours of using air conditioning-called as low-carbon savingenergy technology. (2) According to others research achievements, choosing high carbon fixed plants as community afforestation plants-called as plant carbon fixed technology. (3) Community afforestation spatial layout can be used as the leisure space at general case and can be used as emergency shelter at special period-called as safety carbon technology.
