AB - This paper studies the application of renewable materials in the energy  saving of new building solar greenhouse, and analyzes the influence of  different building materials on the energy saving of solar greenhouse, it  can adjust the angle of the sunlight greenhouse roof manually to improve the  solar radiation into the room and adjust the fan system manually to increase  the heat storage of the back wall. The test greenhouse located in a modern  production base of a city was measured, and the test data under different  weather conditions in winter of 2020 were selected to analyze the  characteristics of temperature and light data indexes in the renewable  material solar greenhouse and common material solar greenhouse, and the  active lighting mechanism and active heat storage mechanism of the  renewable material new building solar greenhouse were theoretically  studied. The results show that the average light transmittance and indoor  illumination of the solar greenhouse with recycled materials are increased  compared with that of ordinary materials under different weather conditions  in winter. In winter solstice, cloudy days and sunny days, the light  transmittance of active daylighting and heat storage solar greenhouse was  61.17%, 58.26%, and 70.81%, respectively, which was 7.87%, 5.88%, and 11.45%  higher than that of ordinary energy-saving solar greenhouse, and the  corresponding indoor illumination was 15.42%, 11.73%, and 21.28% higher than  that of ordinary energy-saving solar green­house. In terms of temperature,  under different weather conditions in winter, the indoor temperature and  ground temperature of the solar greenhouse with active daylighting and heat  storage are significantly higher than those of the control material  energy-saving solar greenhouse. The temperature difference between indoor  and outdoor is above 27ºC.
