Reduction of energy consumption, emissions and carbon footprint of buildings is vital in meeting the EU's climate and energy targets for 2030.

The Near Zero Energy Building concept requires a high level of energy efficiency, in combination with on-site renewable energy production and use.

It is evident that improving the energy performance of buildings calls for retrofit/renovation actions that not only meet the energy and environmental targets, but also ensure minimum disturbance of the inhabitants and indoor comfort.

The PLURAL project aims to tackle this challenge by developing “Plug-and-Use” kits for fast and energy efficient deep retrofitting.

Concept


The key is to understand how to select and integrate various renewable energy technologies, incorporate them in prefabricated façade components and optimize their performance for different building types, climates and socio-economic conditions. PLURAL focuses on how to manufacture these kits while minimising energy use and material waste.

Objectives


The PLURAL project aims to design, validate and demonstrate a palette of versatile, adaptable, scalable, off-site prefabricated plug-and-play kits that account for user needs, thus named “Plug-and-Use” (P-n-U) kits”.

Near zero energy consumption

Heat losses through the envelope will be minimized through improved insulation of the façade components, (U values < 0.23 W/m2K; Building primary energy consumption < 60 kWh/m2).

Cost-effective

About 58% reduction in renovation costs will be achieved through offsite prefabrication, lean manufacturing and construction interactively supported by the BIM based platform and Decision Support Tool.

Fast renovation

At least 50% reduction in the time required for deep renovation mainly by reducing the time to design, procurement, logictics, fabrication and site preparation from avg. 5-7 months to 2-4 months.

Environmentally - Friendly

Deep renovation aiming at reduction of CO2 emissions to reach 15% less than the current average 0.6 tCO2eq/m2 and additionaly to achieve 70% material recyclability.

Flexible

System combinations will allow easy adaptation of the PnU kits to be developed and validated as part of the project to various residential building typologies in all EU climatic zones

Pillars

Fast and adaptable deep renovation towards NZEB
