Urban greening archetypes at the European scale

Jean-Louis Scartezzini, Dasaraden Mauree, Silvia Coccolo, Amarasinghage Tharindu Dasun Perera, Nahid Mohajeri Pour Rayeni, Cynthia Houmani, Ismaël Krafess

Urban greening has great ecological, social and economic benefits for the built environment. It also has significant impacts on the microclimate and urban energy balance. In this study, we quantify the impacts of urban greening on the ground surface temper ...

Using lakes and rivers for extraction and disposal of heat: Estimate of regional potentials

Alfred Johny Wüest, Adrien Gaudard, Martin Schmid

There is increasing interest in using waterbodies as renewable energy sources to heat and cool buildings and infrastructure. Here, we estimate the potentials for heat extraction and disposal for the main lakes and rivers of Switzerland based on acceptable ...

Embodied Energy and Lifecycle Costs: Questioning (Mis)conceptions about Underground Construction

Philippe Thalmann, Aurèle Parriaux, Michael Robert Doyle

In the construction community, underground construction is perceived as being significantly more costly and more energy-consuming than comparable surface construction. Although the literature is scarce, studies that have attempted to quantify this differen ...

Modeling the performance of cool pavements and the effect of their aging on outdoor surface and air temperatures

Flourentzos Flourentzou

Aiming at the improvement of a dense urban area's microclimatic conditions, this study examines by simulation means, the application of highly reflective materials as a mitigation strategy. However, as significant albedo changes may occur due to weathering ...

3D model discretization in assessing urban solar potential: the effect of grid spacing on predicted solar irradiation

Marilyne Andersen, Giuseppe Peronato

The increasing interest in solar energy production in urban areas requires an accurate simulation of solar irradiation on building surfaces, including vertical surfaces. However, solar potential analyses are usually conducted on 2.5D models, which are limi ...

Assessing visibility in multi-scale urban planning: A contribution to a method enhancing social acceptability of solar energy in cities

Jean-Louis Scartezzini, Christian Roecker, Maria Cristina Munari Probst, Josef Andreas Schuler, Pietro Florio

Urban areas are facing a growing deployment of solar photovoltaic and thermal technologies on building envelopes, both on roofs and on façades. An effective solar energy planning process considers social acceptance, in relation to the landscape alteration ...

Differential cooling and near-shore dynamics in a large lake (Lake Geneva)

Ulrich Lemmin, Rafael Sebastian Reiss

Density currents generated by differential cooling in lakes with shallow shore regions or side basins are associated with increased vertical mixing, deep water renewal and cross-shore transport of nutrients and other substances. Previous field experiments ...

Effect of meso-scale surface water temperature heterogeneity on surface cooling estimates of a large lake: Airborne remote sensing results from Lake Geneva

David Andrew Barry, Ulrich Lemmin, Abolfazl Irani Rahaghi

Satellite thermal images are frequently used in the study of surface heat exchange dynamics over lakes. Such investigations can depict large-scale thermal patterns with a resolution of O(1 km2), but not meso- or small-scale processes, requiring O(1 m) and ...

Assessing the photovoltaic potential of flat roofs: Insights from the analysis of optimised array arrangements

Marilyne Andersen, Sergi Aguacil Moreno, Giuseppe Peronato, Adrien Legrain

PV installations on flat roofs offer a wide range of design options, which are usually neglected in urban-scale assessments as these typically assume horizontal or other fixed arrangements. In this study, we analyse the influence of common design parameter ...

Sensitivity analysis of visual and thermal parameters for energy savings: combining illuminance and temperature set-points for possible trade-offs

Marilyne Andersen, Jan Wienold, Joshua Pereira, Giorgia Chinazzo, Mathieu Plourde

This study presents a methodology for evaluating the effects of simultaneous temperature and illuminance set-point variations on energy consumption. Different illuminance levels are achieved with an innovative dynamic shading control algorithm that allows ...
