我国推广绿色节能建筑的障碍及对策建议

绿色节能建筑对我国经济的发展意义重大,对我国房地产市场的发展也有重要的影响。我国房地产开发商绿色建筑理念缺失,应借鉴其他国家推广绿色建筑的经验,加强宣传,增强房地产开发商的社会责任感,加强示范项目的推广,不断完善法律法规,加强经济激励,以大力推广绿色节能建筑在我国的发展。     

低碳经济背景下绿色建筑的经济效益分析

随着社会的发展,我国的建筑行业也在不断地发展中。与此同时,绿色建筑作为可持续发展的理念支撑。它不仅在生态、绿色、环保、健康、节约等方面有着非常重要的影响,还推动着建筑行业的发展,成为目前建筑行业的发展方向。但是,绿色建筑在一开始兴起的时候,它的成本就比较的高,因此,没有很好的经济效益,从而就对绿色建筑的发展造成了消极的影响。不利于绿色建筑的发展。针对绿色建筑的低碳经济效益展开了一系列的分析和探究,希望能够对绿色建筑发展起到推动作用。

Solar optical properties of thin films of Cu, Ag, Au, Cr, Fe, Co, Ni and Al

The optical properties of metal coated glass substrates have been investigated. Thin films of various thicknessesof the noble metals: Cu, Ag, Au, the transition metals: Cr, Fe, Co, Ni and the free electron-like metal Al were thermally evaporated onto glass substrates. The front and backside reflectance and the transmittance between 0.35 and 15 μm were measured. The obtained data were used to calculate the integrated values of solar reflection and transmission as a function of metal film thickness. The application of metal films on domestic windows as sun-screens and heat-mirrors are discussed. It is concluded that Cu is the best coating in a window system if good heat insulating properties are desired. This is due to its ability to remain continuous at very thin film thicknesses. An infra-red reflectance of 86 per cent combined with a solar transmittance of 55 per cent was obtained for a 70film. For solar heat-protection Au-films are found to be superior owing to their transmittance peak in the middle of the visible wavelength region. The transition metals are less selective than the noble metals, but due to their flat response-curves in the visible range they cause a smaller change in colour of the transmitted and reflected light.     

Components,formulations, solutions,evaluation, and application of comprehensive combustion models

Development and application of comprehensive, multidimensional, computational combustion models are increasing at a significant pace across the world. While once confined to specialized research computer codes, these combustion models are becoming more readily accessible as features in commercially available computational fluid dynamics (CFD) computer codes. Simulations made with such computer codes offer great potential for use in analyzing, designing, retrofitting, and optimizing the performance of fossil-fuel combustion and conversion systems.The purpose of this paper is to provide an overview of comprehensive combustion modeling technology as applied to fossil-fuel combustion processes. This overview is divided into three main parts. First, a brief review of the state-of-the-art of the various components or submodels that are required in a comprehensive combustion model is presented. These submodels embody mathematical and numerical representations of the fundamental principles that characterize the physico-chemical phenomena of interest. The submodel review is limited to those required for characterizing non-premixed, gaseous and pulverized coal gasification and combustion processes. A summary of the submodels that are available in representative computer codes is also presented.Second, the kinds of data required to evaluate and validate the predictions of comprehensive combustion codes are considered. To be viewed with confidence, code simulations must have been rigorously evaluated and validated by comparison with appropriate experimental data, preferably from a variety of combustor geometries at various geometric scales. Three sets of validation data are discussed in detail. Two sets are from the highly instrumented, pilot-scale combustor called the controlled profile reactor (CPR) (one natural gas-fired and one coal-fired), and the other set is for a full-scale, corner-fired 85 MW_e utility boiler.Third, representative applications of comprehensive combustion models are summarized, and three sets of model simulations are compared with experimental data. The model simulations for the three test cases were made using two commonly used, CFD-based computer codes with comprehensive combustion model features, PCGC-3 and FLUENT 4.4. In addition to the standard version of FLUENT, predictions were also made with a version of FLUENT incorporating advanced submodels for coal reactions and NO pollutant formation.
