Abstract [en]

This thesis examines how ICT solutions can assist in lowering energy use and greenhouse gas (GHG) emissions from buildings and travel in order to help cities meet their climate targets. It also provides an overview of relevant research intended to furnish new knowledge about the issues involved and to find solutions to social problems.

The first part of the thesis provides an analysis and compilation of critical system boundaries that need to be used for cities to set targets for energy use and GHG emissions. The climate targets of cities are dependent on setting system boundaries and establishing methods of calculations for monitoring whether the targets have been achieved. Today, there is no official standard for how the system boundaries must be set or what calculation methodologies to apply to evaluate the climate targets. Four main categories of system boundaries were identified: the temporal scope, the object of target setting, the unit of target setting, and the target range (e.g. consumer-producer and lifecycle perspective). Eight European cities were examined in relation to how they set climate targets. The examination showed that awareness of what is included in the targets is limited and that there is a need for standardised and consistent protocols and methods of setting climate targets for cities.

In the second part of the thesis, leading Advanced Traveller Information Systems (ATIS) and their functionalities were investigated. The relationship between individual decisions on different travel modes and functionalities of ATIS was investigated through a systematic investigation of the functionality of nine ATIS, mainly from Sweden, Germany, UK and USA. This allowed decisions that could lead to lower energy use and emissions of GHG to be identified. It also resulted in a proposal on requirements for new and improved functionality that could support a reduction in energy use and GHG emissions and a shift to renewable energy sources if implemented in next-generation ATIS.

In the third part of the thesis, ICT applications that can be used to reduce energy use and GHG emissions of buildings within the already built environment were identified. In addition, a brief analysis was made of how different actors such as the tenant, the building owner and the energy provider can reduce energy usage in buildings by means of ICT solutions.

Abstract [en]

Cities’ climate targets are dependent on system boundaries and methods of calculations. This article identify, explore and present an overview of methodological considerations of importance in order to facilitate understanding, comparing and setting targets for green house gas emissions and energy use in cities. A survey on how eight European cities set their climate targets is presented. A framework of methodological considerations that are of importance when setting targets for cities is presented. A review of existing GHG accounting protocols, three major sustainable city frameworks and a selection of scientific papers reporting on accounting methodologies was used as a basis for developing the methodological considerations. Four main categories were identified, temporal scope, object for target setting, unit of target, and range of target. For each category there is an in-depth discussion of them in relation to targets for cities. The survey of the European cities showed that there is quite a little awareness of what is, or could be, included in the targets. This makes comparison and benchmarking almost impossible today. It also shows the need for comprehensive and consistent accounting protocols and methodologies.

Abstract [en]

This article identifies and explores connections between travel decisions by individuals and different functions in Advanced Traveler Information Systems (ATIS). Ways of encouraging decisions that could lead to lower energy usage and emissions of greenhouse gases (GHG) were sought. A systematic investigation of the functionality of nine ATIS, primarily from Sweden, Germany, the UK, and the US, resulted in a proposition for improved functionalities, which could enable the next generation of ATIS to contribute to lower energy usage and GHG emissions
