WP4 | Up-Scalling of Climate Change Impacts on Cities


The Work Package 4 is responsible for quantifying the influence of short-term (more and more recurrent heat waves) and long-term (global warming) climate change on heating, ventilation and cooling energy demands, decentralized power production by means of photovoltaic panels and final energy consumption for the Belgian residential building stock.

T

his quantification will be achieved by means of a simulation/numerical model of the national/regional residential building stock. They will also investigate the impact of projection of future climates on the energy performance of building and thermal comfort at the national level. The profiles of energy demand for the residential building stock will be determined with a time step small enough to quantify the overheating stress in a building. Such a small-time step will allow providing information to the electricity grid operators on the impact of climate changes on the electrical loads they have to balance with power production. In parallel to the scenarios of climate changes, different scenarios of building renovation/demolition/construction and different scenarios of use of HVAC (heating, ventilation and air-conditioning) technologies will be assessed. They will investigate how appropriate HVAC technologies could offer resilient cooling solutions and limit the overheating in new and renovated buildings, while ensuring high building energy performance by simulating the current cooling systems for residential buildings as well as the future trends in the market.

Objectives:

  • Quantifying and upscaling the impact of climate change in terms of overheating risks on the building stock in Wallonia.
  • Identifying the impact of climate change on heating, ventilation and cooling energy demands.
  • Evaluating and Assessing the appropriate HVAC technologies that could limit the overheating risks in the selected building stock.
  • Providing the needed information to electricity grid operators on the impact of climate change on electrical loads to balance with the power production.
