Research on Performance of Humidity-controlling Materials Based on E+

Energy-saving building quantitative assessment is often based on three major aspects. First, the building energy consumption; second, human comfort; third, the whole life cycle cost. The application of high-quality humidity-controlling materials will optimize these three indicators. At present, active air conditioning adjustment is also mainly used to meet building internal humidity demand in China. Though it can meet the comfort requirements of architectural space, the building energy consumption is large. It is not in accordance with the sustainable development strategy. Using humidity-controlling materials is passive, green, non-pollution, zero-energy and sustainable way with great potential development space. The paper simulated a building with different envelope inner surface humidity-controlling materials from human comfort, energy consumption and economy of three aspects by energy consumption analysis software EnergyPlus. Meanwhile painting as control group is contrasted and analyzed. The results showed that humidity-controlling materials have great advantages in these three aspects. Humidity-controlling materials can regulate indoor air humidity and reduce energy consumption. Besides the whole life cycle cost can get to minimum. This article provides a theoretical basis and a technical guidance for humidity-controlling materials market promotion and building energy saving.
