Solar photovoltaic thermal (PVT) is an emerging technology, capable of producing electrical and thermal energy using a single collector. However, to achieve larger market penetration for this technology, it is imperative to have an understanding of the energetic performance for different climatic conditions and the economic performance under variou...

Positive Energy Districts (PED) require integration of different systems and infrastructures for the optimal interactions among buildings, stakeholders, mobility, energy systems and ICT systems. Digital twin is a coupled approach for new forms of modelling and analysis based on big data and machine learning/artificial intelligence, which combines c...

Solar heating technologies hold a significant potential to supplement or replace the fossil fuel-driven heating systems in residential and industrial applications. This paper presents a techno-economic study aiming to assess the use of Unglazed Transpired Solar Collectors (UTSC) coupled with an energy system assisted by Exhaust Air Heat Pump (EAHP)...

A digital twin is regarded as a potential solution to optimize positive energy districts (PED). This paper presents a compact review about digital twins for PED from aspects of concepts, working principles, tools/platforms, and applications, in order to address the issues of both how a digital PED twin is made and what tools can be used for a digit...

The COVID-19 outbreak is exacerbating uncertainty in energy demand. This paper aims to investigate the impact of the confined measures due to COVID-19 outbreak on energy demand of a building mix in a district. Three levels of confinement for occupant schedules are proposed based on a new district design in Sweden. The Urban Modeling Interface tool...

The deployment of solar photovoltaics (PV) and electric vehicles (EVs) is continuously increasing during urban energy transition. With the increasing deployment of energy storage, the development of the energy sharing concept and the associated advanced controls, the conventional solar mobility model (i.e., solar-to-vehicles (S2V), using solar ener...

This paper proposes an integrated simulation framework for both building design and energy performance analysis. Literature review shows that, although many studies exist, most of them did not fully consider the integrated techno-economic evaluation of building-integrated photovoltaic (BIPV) system. Therefore, this research aims to use the interope...

Experimental analysis and performance mapping of various CST technologies for Indian climatic locations

This thesis presents an optimisation approach and techno-economic evaluation tool for a system consisting of a transpired solar air collector and air source heat pump in a series arrangement. The thesis also investigates the application of the developed tool for feasibility study of a solar heat pump system for a group of three multi-family houses...

With depleting conventional energy resources, whole world is now looking for alternatives to meet energy demands. One of the solutions is renewable energy which is non-exhaustible and non-polluting, but problem is intermittent nature of these energies. Hybrid models have been an effective means of generating electricity throughout the world. Lots o...
