Abstract: Based on the energy saving reconstruction of an existing office building in Hangzhou, this paper analysis the building energy consumption through the DEST simulation at the present phase. Then summarize the deficiency and reconstruction of the building, and accordingly we propose a reconstruction scheme for the building which is based on the primary research about the optimization strategy of energy saving. This will provide a strong basis about the energy saving reconstruction direction and the reconstruction emphasis of the office building in hot summer and cold winter area.

Abstract: Bio-drying reduces the moisture content of sludge without other external energy consumption, this paper introduced the microbiological aspect of a bio-drying process ,and state briefly about the suitable scope of oxygen supply ,C/N ratio, pH of biomass and moisture content for a optimal heat generation.

Abstract: Bio-drying is an important method to reduce the excess sludge which use the inner biomass of sludge itself to generate heat for a water discharging has a broad prospects in sludge treatment. However, our research in this field is still very limited. In order to better mastering and promoting sludge bio-drying technology, this paper summarized the advantages of bio-drying, initially described the microbial mechanism of spontaneous heat generation and the heat and mass transfer phenomena in a bio-drying process, then build a macro heat conservation formula based on material conservation.
