Introduction
A doctoral researcher in thermodynamics laboratory in university of liege in Belgium, a former research assistant in Fraunhofer-ISE in energy efficient buildings department. I'm currently working on the impact of climate change on the indoor environmental and energy performance of buildings and Investigating the impact of projection of future climates on the energy performance of buildings at the national level. I am also an active member in "IEA-EBC Annex 80; resilient cooling" project.

Conference Paper
Full-text available
The paper investigates the evolution of electricity-driven and gas-driven heat pumps technologies used for heating in the residential building stock in Belgium in the market. A base and predictive scenarios are considered. The base scenario includes the current share of the existing heat pumps in the Belgian market while the predictive scenario con...
Conference Paper
Full-text available
In moderate climates, using natural ventilation systems could allow to save up to 60 % of the end energy for ventilation and air conditioning. Natural ventilation systems depend on pressure differences to move fresh air into buildings by wind effect and pressure effect. Night cooling can be achieved either by an increased air change rate. The highe...
Article
Full-text available
Nearly zero-energy buildings (nZEBs) will be the standard in Europe in the future. How nZEBs are defined and therefore designed varies amongst Europe due to different national definitions/legislations. Furthermore, finding the optimal building design and technology sets for nZEBs under different boundary conditions (climate, availability of renewab...
Conference Paper
Full-text available
In the coming years, global warming will have a large impact on many aspects of the environment and human activities in buildings. The objective of the ongoing study, of which some results are presented in this paper, is to upscale the impact of climate change on the Belgian residential building stock and to evaluate its influence on the future hea...
Article
Full-text available
One pavilion was selected for deep retrofitting from the OttoWagner area situated in the west of Vienna. The retrofitting process involves sustainable and energy-efficient construction to improve the energy performance and energy production potential of the building while preserving the cultural heritage and significance. This four-story pavilion w...
Article
Full-text available
Global warming is widely recognized to affect the built environment in several ways. This paper projects the current and future climate scenarios on a nearly zero-energy dwelling in Brussels. Initially, a time-integrated discomfort assessment is carried out for the base case without any active cooling system. It is found that overheating risk will...
Conference Paper
Full-text available
Buildings in the EU account for 40% of our energy consumption and 36% of our greenhouse gas emissions, with HVAC systems being the biggest contributors. With the predicted increase in global air temperature up to 4.8 K by the end of this century, cooling will be the most rapidly increasing energy-consuming technology in buildings. Heat pumps are on...
Article
Full-text available
Increasing temperatures due to global warming will influence building, heating, and cooling practices. Therefore, this data set aims to provide formatted and adapted meteorological data for specific users who work in building design, architecture, building energy management systems, modelling renewable energy conversion systems, or others intereste...

Article
Full-text available
The global effects of climate change will increase the frequency and intensity of extreme events such as heatwaves and power outages, which have consequences for buildings and their cooling systems. Buildings and their cooling systems should be designed and operated to be resilient under such events to protect occupants from potentially dangerous i...
Article
Full-text available
For the Otto Wagner area which is situated in the west of Vienna, one pavilion is selected to be refurbished for sustainable and energy-efficient construction to simulate the thermal and energy performance of the building. The selected pavilion has been redesigned to be used as a student residence while preserving the cultural heritage. A dynamic b...
Technical Report
Full-text available
This report summarises results of Work Package ‘WP04 – Cost reduction potentials for nZEB technologies‘, task 4.2 ‘Development of low costs solutions sets (construction concepts, building technical systems including renewables)’. It is part of the Horizon2020 - CRAVEzero project. Cost optimal and nearly zero-energy performance levels are principle...
