An integrative approach for embodied energy: Towards an LCA-based data-driven design method

Marilyne Andersen, Emmanuel Rey, Thomas Bernard Paul Jusselme

The built environment is one of the major contributors of greenhouse gas (GHG) emissions. To tackle climate change, global targets have been set for this sector. Although life-cycle assessment (LCA) methods are typically used to evaluate a building project ...

2018

Neighbourhood-scale Evaluation to Benchmark the Integration of Urban Sustainability (NEBIUS). An innovative education and research methodology

Emmanuel Rey, Sophie Lufkin

The holistic nature of sustainability has radically transformed architectural and urban design practices. On the one hand, it enforces the need for simple, efficient, graphical assessment tools to support communication among the stakeholders. On the other ...

Towards integrated design strategies for implementing BIPV systems into urban renewal processes: first case study in Neuchâtel (Switzerland)

Emmanuel Rey, Sophie Lufkin, Sergi Aguacil Moreno

In view of the importance of urban renewal processes, building-integrated photovoltaic (BIPV) systems can potentially provide a crucial response to the challenges of the energy turnaround. Functioning both as envelope material and electricity generator, th ...

Influence of energy-use scenarios in Life-Cycle Analysis of renovation projects with Building-Integrated Photovoltaics – Investigation through two case studies in Neuchâtel (Switzerland)

Emmanuel Rey, Sophie Lufkin, Sergi Aguacil Moreno

Since tomorrow’s cities are already largely built, and as many of their buildings – with a low level of energy performance – will still be standing in 2050, urban renewal processes play an essential role towards the sustainable development of European citi ...

H. Elsharkawy, S. Zahiri, J. Clough2017

LCA as key factor for implementation of inertia in a low carbon performance driven design: the case of the smart living building in Fribourg, Switzerland

Marilyne Andersen, Emmanuel Rey, Thomas Bernard Paul Jusselme, Endrit Hoxha, Arianna Brambilla

The building sector is known as a major contributor to greenhouse gas (GHG) emissions and energy consumption. These impacts are commonly evaluated by life cycle assessment (LCA), which assess the potential impacts of a building from the construction to the ...

2016

Designing with building-integrated photovoltaics (BIPV): A pathway to decarbonize residential buildings

Emmanuel Rey, Sophie Lufkin, Sergi Aguacil Moreno, Sebastian Duque Mahecha

The ambitious targets set for greenhouse gas emissions and energy efficiency by 2050 demand a critical increase of building renovation rates. This challenge is shared by most Western nations, including Europe and Switzerland, where the current annual renov ...

Towards an innovative temporary event structure based on bioclimatic principles

Emmanuel Rey, Loïc Vivien Fumeaux

Switzerland has adopted the concept of the 2000 Watts society as a long term target, with an intermediate objective for 2050: a reduction of the average energy consumption per person from 6300 to 3500 watts, including a maximum of 2000 watts of non-renewab ...

2014

An innovative architectural strategy for the integration of energy issues into the design process of a commercial center in Switzerland

Emmanuel Rey, Sophie Lufkin

In a context of growing efforts to develop sustainability strategies, energy-related issues occupy central stage in the built environment. Thus, the energy performance of housings has improved radically over the past decades. Yet other types of buildings, ...

Predictive models for assessing the passive solar and daylight potential of neighborhood designs: A comparative proof-of-concept study

Marilyne Andersen, Emmanuel Rey, Émilie Nault

Despite recent developments, neighborhood-scale performance assessment at the early-design phase is seldom carried out in practice, notably due to high computational complexity, time requirement, and perceived need for expert knowledge, ultimately limiting ...

2017

A Multi-Criteria Decision-Support Workflow for Early-Stage Neighborhood Design based on Predicted Solar Performance

Marilyne Andersen, Emmanuel Rey, Émilie Nault

Despite recent developments, the need for adequate guidance and support in the early decision-making process of urban planners, designers, and architects has recurrently been recognized. Traditional performance assessment methods, which are often based on ...

Integrative decision-making strategy for fluvial neighborhoods in transition

Emmanuel Rey, Martine Laprise, Sara Sonia Formery Regazzoni

The changing relationships between cities and their waters over the centuries lead today – after a clear sidelining of rivers in the city – to question their potential for building new interactions. Current densification objectives of the existing built fa ...

An operational monitoring tool facilitating the transformation of urban brownfields into sustainable neighborhoods

Emmanuel Rey, Sophie Lufkin, Martine Laprise

The regeneration of urban brownfields is a relevant strategy to limit the sprawling of post-industrial European cities. However, the integration of sustainability issues in urban brownfield regeneration projects is not a spontaneous process, remaining in m ...

From ecological construction to sustainable urban development : the Ecoparc project in Neuchâtel (Switzerland)

Emmanuel Rey

The present logic of built environment dispersion appears incompatible with the concept of sustainable development. The peripheral expansion of cities is indeed leading to irrational use of ground, growing environmental impact and important infrastructure ...

EPFL2005

Findings from a survey on the current use of life-cycle assessment in building design

Marilyne Andersen, Emmanuel Rey, Thomas Bernard Paul Jusselme

The built environment is facing environmental regulations more ambitious than ever before. In Europe, a law will lead all new buildings to the Nearly Zero-Energy performance level. However, even if a building does not have any energy consumption for its op ...

PLEA2018

Comparative approach of the environmental impact induced by different architectural visions of a new periurban neighbourhood

Emmanuel Rey, Sophie Lufkin, Sergi Aguacil Moreno, Martine Laprise

The objective of this research work is to compare the environmental impact, expressed in terms of non-renewable cumulative energy demand (CEDnr) and greenhouse gas (GHG) emissions, of nine architectural visions for a new neighbourhood located in the periur ...

Energy transition challenges in under-occupied homes: Assessment of two peri-urban neighbourhoods of single-family houses

Emmanuel Rey, Judith Elisa Drouilles

Current planning policies aim at putting a stop to urban sprawl by favouring densification processes. In this context, future developments are more likely to happen in strategic urban areas than in existing peri-urban neighbourhoods of single-family houses ...

2020

Active renovation strategies with building-integrated photovoltaics (BIPV). Application on an early 20th century multi-family building

Emmanuel Rey, Sergi Aguacil Moreno

Tomorrow's cities are already largely built, as much of the existing building stock – with a low level of energy performance – will still be standing in 2050. Urban renewal processes therefore play an essential role towards the sustainable transition of Eu ...

Linking spatial characteristics to residential lifestyles. A framework for analysing the hospitality potential of urban and architectural designs

Vincent Kaufmann, Emmanuel Rey, Sophie Lufkin, Marie-Paule Thomas

Today, in many European countries, increasing opposition tends to thwart urban densification projects. To enhance public acceptability of such projects, which are likely to promote sustainable urban development, it is essential to better anticipate urban p ...

An Indicator System for the Assessment of Sustainability Integrated into the Project Dynamics of Regeneration of Disused Urban Areas

Emmanuel Rey, Sophie Lufkin, Martine Laprise

In the context of sustainable densification of post-industrial European cities, urban wasteland regeneration projects offer an important potential of surfaces to recapture. Indeed, these projects can contribute concurrently to densify and revitalize existi ...

Environmental impact assessment of Swiss residential archetypes: a comparison of construction and mobility scenarios

Emmanuel Rey, Sophie Lufkin, Sergi Aguacil Moreno, Thomas Bernard Paul Jusselme, Endrit Hoxha, Judith Elisa Drouilles

Environmental performance assessment of the built environment tends to focus mostly on operational final energy consumption of buildings located within a specific context. Such a limited scope prevents broader usability of findings in practice. In Switzerl ...
