Inspired by state-of-the-art material science, computer techniques, artificial intelligence, and automatic control, new-generation transportation infrastructures are becoming digitalized intelligent. Many major developed countries around the globe actively promoting application of innovative intelligence-based technologies in accordance with local conditions. This review begins a brief discussion on basic definition, scientific foundation, development process for intellectualization...

Each year around 200 million tons of demolition wastes are produced from aging U.S. infrastructures. Of that amount, 100 portland cement concrete debris. Disposal these in landfills has been a traditional solution, but environmental regulations, costs, and lack landfill areas have hindered safe disposal. These problems led to search for alternate ways reusing by recycling. Recycling the waste not only reduces disposal problem also quarrying virgin aggregate. The incorporation recycled as...

The energy performance of a building in dense city depends to some extent on its surroundings. impact the built form, together with anthropogenic heat gains from traffic and HVAC exhaust, determines external environmental conditions at Urban Canopy Layer. Existing models are limited accounting for micro-scale variations urban microclimate, which may significantly modify building's density cities. This paper presents Building Energy Climate (UrBEC) model, coupled microclimate model (UMM)...

Further research is needed on the capability of residential communities to achieve energy self-sufficiency under constraints current standards land use, in particular for Hot Summer and Cold Winter climate zone (HSCW) China, where majority are dominated by high floor-area ratios, thus high-rise dwellings, namely less solar potential per unit floor area, while most residents adopt a “part-time, part-space” pattern intermittent use behavior, using relatively low area. This study examines 150...

Occupant behavior has an important impact on building energy consumption, and the accuracy of occupant model directly affects reliability consumption simulation results. Ultra-low buildings are crucial to achieving conservation carbon dioxide reduction in China. In order effectively promote development ultra-low Hot Summer Cold Winter Climate Zones. where most residents adopt a “part-time, part-space” pattern intermittent use behavior, solve problem poor indoor thermal environments high...

In order to inform the design of a building or group buildings in relation their potential energy efficiency, main impact will be at initial concept stage. Variations and interactions parameters need considered quickly as develops. addition variation interrelation associated with individual buildings, should consider influence, both from on, neighbouring landscape features. This paper describes development two modelling processes, based around established model, HTB2, urban scale model EEP....

Based on a monopoly model in industrial symbiosis chain including one upstream manufacturer and downstream manufacturer, the price sensitive-environmental concern demand is introduced into paper. The decision behaviors of manufacturers under environmental regulations imposed by policy makers or government waste emission standard, tax subsidy for usage are investigated. results show operational factors must be taken account right formulation simultaneous implementation external performance...

There is a global trend to deliver zero carbon buildings, with European countries required near energy housing by 2020. This paper presents the results of simulation performance SOLCER house. The house was designed using ‘systems’ approach integrate building technologies for thermal and electrical systems, based on concept buildings as power stations, renewable systems part envelope. aim produce that achieves an ‘energy positive’ performance, which, annual basis, generates more than in...

Abstract The spatial distribution of the sediment nitrogen in ten typical estuaries Lake Taihu was determined. A simple quantitative estimation model and principal component analysis (PCA) method were applied to find source major factors estuarine loading. average concentrations total (TN), organic (Org-N), ammonium nitrate-nitrogen sediments 1315.5, 1220.1, 82.53 6.45 mg/kg, with fraction dominating. Results showed a significant difference for TN concentration different estuaries, which...

District Heating Systems (DHS) have received renewed attention in relation to their environmental, economic, and health benefits. Research literature on DHS tends focus separately, either the thermo-hydrological modelling or building energy demand. Rarely are there combined simulation approaches that consider interactions between district heating system buildings they serve. There is a practical need for coupled model inform operation retrofit strategies, such as, insulation, water leakage...

High-strength concrete-encased-steel filled CFRP (carbon fiber reinforced polymer) tube (HCSFC) takes advantages of high strength concrete, steel and confinement FRP, resulting in enhanced structural load carrying capacity deformability. In this study, expansive high-strength concrete is between sectional to study the mechanical properties (HECSFC) under monotonic cyclic axial compression. Twenty-four specimens were fabricated study. The variables included number layers (0, 1, 2 layers),...

This paper presents the results for operating energy performance of smart operation a low carbon region (SOLCER) house. The house design is based on ‘systems’ approach, which integrates building technologies electrical and thermal systems, together with architectural design. It concept ‘energy positive’ buildings, utilising renewable systems form part envelope construction. describes how model HTB2, range additional ‘plugins’, has been used to simulate specific elements overall Measurement...
