REZBUILD Project supports COP24, a conference that seeks to help in the reduction of greenhouse gas emissions and the slowdown of lobal warming
The city of Katowice (Poland) will hold from 2 to 14 december the UN Climate Change Conference COP24. The main objective of this conference is to adopt the implementation guidelines of the Paris Climate Change Agreement in order to help in the reduction of greenhouse gas (GHG) emissions and the slowdown of global warming.
In addition, and related to sustainability in constrution sector, on the 4 of december there will be celebrated the theme day Building Green, in order to analyze how we can achieve sustainable buildings to get a low-carbon society and fight against climate change.
With this objective, the EU’s buildings sector needs to develop and deploy more innovative solutions in order to enhance the building stock’s energy efficiency and help meet energy and climate policy targets.
Nowadays, buildings are responsible for approximately 40% of energy consumption and 36% of CO2 emissions in the EU. Currently, about 35% of the EU’s buildings are over 50 years old and almost 75% of the building stock is energy inefficient, while only 0.4-1.2% (depending on the country) of the building stock is renovated each year.
Therefore, more renovation of existing buildings has the potential to lead to significant energy savings – potentially reducing the EU’s total energy consumption by 5-6% and lowering CO2 emissions by about 5%.
By renovating and making our buildings in Europe smarter and energy efficient, Europe can ralize a several simultaneous benefits, including lower energy bills, better health, protection of the environment and reduction of our greenhouse emissions in the EU. In this sense, The Energy Performance of Building Directive (EPBD) requires every new building to be a Nearly Zero-Energy Building by the end of 2020.
Towards an innovative refurbishment ecosystem
Fully aligned whith european policies, Rezbuild Project’s objective is to develop one refurbishment ecosystem based on the integration of cost-effective technologies, business models and life cycle interaction for deep NZEB renovation to diverse residential renovation typologies and interconnecting both, building renovation stages and stakeholders.
This ecosystem will ensure the fulfilment of three KPIs:
1)A deep renovation rate at least 60% of primary energy reduction as a result, the application of a decision tree strategy created from the combination of united principles of the novel sustainable architecture and NZEB design concepts
2)A reduced installation time at least a 30% of time saving in comparison with a traditional refurbishment works,and
3)A rapid payback period maximum 12 years of the best retrofitting technology package installed in the residential building.
In addition, REZBUILD Project is fully aligned with sustainable development goal 13 with the main objective of taking action to combat climate change and its impacts.
