Results and Discussion
Starting from these objective data, simulations under dynamic conditions were performed with the TRNSYS.
Seeing Table 3, it is possible to observe a progressive reduction of the thermal transmittance that is important to decrease the heating energy demand and, at the same time, a solar gain factor reduction that is important to decrease the cooling energy demand.
Energy demands reduction ranges from 20.8% to 27.8% regarding heating and from 6.6% to 26.3% regarding cooling.
It is clear that the highest cooling reduction value (26.3%) is related to the lowest triple glazing g-value.
The highest cooling reduction value (26.3%) is connected to the lowest triple glazing g-value.

Urban emission reduction can be taken into meticulous management.
Based on high resolution remote sensing data we can automatically extract the data of piling up waste, which has area greater than 100 ㎡ or more like construction waste, industrial waste, mixed garbage and solid waste.
Using CORS system builds on the bedrock of base stations in crustal deformation monitoring network, using observation data of base station, crustal deformation accumulation area, provide experimental data for urban earthquake forecast.
The result of basic surveying and mapping provides spatial data base for city management.
New data clustering method for farmland evaluation based on fuzzy-hyper graph model.

With 6000h of operation time, those reductions of the pressurized air lead to energy savings of 11240 kWh per year.
Fig. 2 Reduction of losses due to adaptive consideration of linked flux Energy efficient auxilliary components of the machine tool.
To forecast the future using profile of a production machine data can be taken from • Historic data (ERP-system, Maintenance data), • Live measurements and extrapolation and • Expert estimations.
A method to gain such data is presented by [14].
In the η-factory this will be realized by an energy control system which is based on live data measurements and by simulation approaches for key technologies.

Narrowly speaking, low-carbon industry refers to industries directly related to carbon elimination and reduction, the core is clean energy and energy saving technology; broadly speaking, low-carbon industry may include all industries which is helpful to contribute to energy saving and emission reduction.
In one word, low-carbon industry is the basis of low-carbon economy, measured by carbon emission reductions, based on carbon reduction technology and involved collection of low-carbon production and service industries.
Table 2 summarizes the data of the level of energy consumption of the whole society, Shenzhen are much higher than the national average in primary energy consumption and non-fossil energy sources.
Data of public transportation from 2005 to 2012 is shown in Table 3, and Table 4 shows the environmental protection investment in recent years.
According to statistics data of Municipal Bureau of Statistics, the added value of new energy industry was 25.41 billion yuan, increased by 20.7% in 2011.

From map data analysis and satellite images of Google Earth, we find the presence of large-scale over-reclamation at Taiwan’s main mountain ranges.
Research Methods and Purpose Our methods include literature review, map and data analysis, semi-structured interviews, sample analysis and depth interviews.
The supplementary data collected from experts and policy officials during the interviews would help create a better understanding on the planning decisions of climate change reduction issue.
Based on statistical data of the Water Resources Agency, the agricultural water use had amounted to 12.205 billion cubic meters in 2015, accounting for 71.53% of the island’s total water consumption.

The fraction recrystallized
calculated from the experimental softening data was then verified by quantitative metallography at
300°C.
Excellent agreement was observed between the fraction recrystallized calculated from the mechanical testing data and estimated from the quantitative metallography results.
Recrystallized grain size: The CC material produces a finer recrystallized grain size as compared to the recrystallized IC material (20μm for the CC material as compared to 30μm for the IC material for 40% cold reduction).
Using equations (2) and (3), it then possible to calculate that the change in electrical resistivity expected from a reduction in dislocation density as 0.4nΩm which is again within the margin of error for the experimentally measured value of 0.5±0.2nΩm (all data shown in Table 5).
We would also like to acknowledge Johnson Go of UBC for providing softening data for ingot cast AA5754 material.

As a result, VGM models of HC function underestimate the unsaturated HC and show rapid reduction near saturation.
The measured data on soil water retention are fitted and integrated to van Genuchten-Mualem model.
Especially, the model predicts abrupt reduction near saturation.

These variable pitch control systems have several advantages over the traditional wind turbines, such as reduction of the mechanical stress, improve quality of electric energy and mitigate tower fore-aft vibration and gearbox vibration.
Introduction Due to reduction of fossil fuels and environmental pollutions, wind is recognized worldwide as a cost-effective, environment-friendly solution to energy shortage.
Such methods are likely to allow a better trade-off between load reduction and pitch fatigue to be achieved [6].
