The important focus of the energy strategy European Union relies on concept zero building (ZEB), which is, by definition, a that roughly produces yearly as much renewable it consumes. This article proposes an enhanced mixed-integer nonlinear programming model for optimal sizing photovoltaic (PV) and battery storage systems to comply with definition ZEB. A salient novel feature proposed is factors in environmental impacts, computed through rigorous life cycle assessment methodology, buying...
Organic Rankine cycles employing carbon dioxide (CO2) for waste heat recovery became popular in the last years thanks to its excellent transfer characteristics and small environmental footprint. Low-grade (<240 °C) represents major portion of excess globally, but it is hard recover due temperature gap source sink leading a poor efficiency cycle. Therefore, numerous modifications power cycle layout were proposed by academia industry — reheated expansion, recuperation intercooled compression...
This study aims towards an improved estimation of annual heat demand the building stock for entire region. requires holistic representation aspects influencing buildings, namely their geometry, fabric, users and surrounding environment. A large data base Swiss canton Geneva was systematically assessed to identify parameters suited these aspects. Due expectable differences in demand, categorized into 8 types. For each type a multiple linear regression model developed predict demand. An aspect...
Industrial waste heat potential has been recurrently quantified in multiple publications. However, actual valorisation opportunities still need to be better assessed. This work focuses on heat-to-power the EU27+UK. In a first step, impact of deployment is per country and major industrial sectors. It demonstrated that 13’089 GWh/y electricity, savings 4’440 ktons/y CO2, investments 7’673 M€, revenues 1’688 M€/y 11’256 jobs would generated case was solely used produce electricity. second...
Considering current environmental issues (e.g. climate change, air pollution) related to energy consumption, this thesis focuses on data characterisation and integrated optimisation methods for waste heat valorisation at the building, city regional scales. As a first contribution, method detailed of demand domestic hot water streams (shower, bath, washing up, etc.) in households building scale is presented. The consumption can be put relation total heating and, by spatial allocation...
