A greenhouse gas accounting tool for regional and municipal climate change management

Regional greenhouse gas (GHG) inventories support the development and monitoring of climate change mitigation and adaptation strategies as well as policies for municipalities and cities. However, information and scientific expertise on climate change impacts are complex and a consensual and consistent methodology on formation of regional GHG inventories is still missing. Available methodologies and calculation tools mostly fail to balance scientific adequacy and usability from a pragmatic per-spective. Within the project Regional Carbon Footprint (RCF), software that allows data management (i.e. for bottom up data) in order to calculate regional greenhouse gas inventories and to report about regional carbon footprints has been developed. Efforts needed for data collection turned out to be the main bottleneck for application from a practitioners point of view. The RCF approach overcomes these shortcomings by closing this gap with the use of top down data taken from statistics.

Energy efficiency benchmarking system for industrial enterprises

The work describes an energy efficiency benchmarking methodology for a high level monitoring of industrial enterprises in order to fulfill the energy efficiency goals of the federal government in Germany until 2020 and 2050. The applicability of the system is not restricted to Germany. Based on statistical energy consumption data of the industrial sectors in the country according to the NACE-Code classification, energy efficiency can be evaluated on different abstraction levels, resulting in different aggregated indicators. At the same time the approach offers for single industrial enterprises to economically monitor the achieved level of energy efficiency and its development over time. The comparability of different companies is based on company specific reference values as turnover, gross value added and number of employees. Characteristic energy efficiency indicators are determined for the company and set in relationship to the mean values of the corresponding industrial sector. These ratio indicators can be recalculated annually and show if the single company is competitive concerning its energy efficiency level and gain. Because of the explanatory power of the introduced benchmarking approach despite simplicity in survey and interpretation, we suggest to use it as incentive system to reward companies with energy efficiency gains of a certain percentage above average in the industrial sector with lower taxation.

Energy efficiency benchmark for industrial SME

The paper suggests an energy efficiency benchmark for a high level monitoring in order to fulfill the energy efficiency goals of the federal government in Germany until 2020 and 2050. Based on statistical energy consumption data of the industrial sectors according to the NACE-Code classification, energy efficiency can be evaluated on different abstraction levels, resulting in aggregated indicators. At the same time the approach offers for single industrial small or medium sized enterprises (SME) to economically monitor the achieved level of energy efficiency and its development over time. This is additionally based on company specific reference values concerning annual energy consumption, turnover, gross value added and number of employees. Characteristic energy efficiency indicators are determined for the company and set in relationship to the mean values of the corresponding industrial sector. These ratio indicators can be recalculated annually and show if the single company is competitive concerning its energy efficiency level and gain. Because of the explanatory power of the suggested benchmark despite simplicity in survey and interpretation, we suggest to use it as incentive system to reward energy efficiency gains of a certain percentage above average in the industrial sector with lower taxation.

Convergent Infrastructures for Municipalities as Connecting Platform for Climate Applications

Since topics such as climate protection come more and more in focus to municipalities, as they are in the role to implement related processes, technical support systems in this area are powerful tools. The most obvious requirement is the implementation of a monitoring infrastructure, which helps to measure the current state of energy consumption in buildings, properties and far beyond, focusing on various sectors such as industry, mobility, waste, etc. Apart, there are requirements and connected technologies and solutions in the fields of Ambient Assisted Living or Smart Home, which can be considered separately from the infrastructure perspective. But, in future, digital services will continuously grow together, simply by the need of various requirements for data exchange in many use cases. In the work at hand we show that in certain areas topics such as IoT in energy management, Ambient Assisted Living or Smart Home solutions should not be considered as separate platforms, but as convergent building blocks of a connected infrastructure landscape. In the context of municipal climate protection, this approach is illustrated in an example case study by presenting a central platform, which allows municipal energy management in conjunction with other services. The development is illustrated based on an innovative software environment that brings the idea in productive application.
