Ensnare

ENvelope meSh aNd digitAl framework for building REnovation

Why Ensnare?

The building sector is one of the main contributors to GHG emissions, being 40% of the energy consumption in the EU associated with building needs, mainly for heating, cooling and domestic hot water purposes. In order to achieve 2050 decarbonisation goals, significant increase in the low renovation rates is needed. ENSNARE provides a systemic methodology combining products, systems and solutions that will facilitate and boost the adoption of novel and advanced technologies during renovation

 

The building envelope is a fundamental element since typically at least 75% of heat losses occur through the envelope comprising façade, roof and windows. Therefore, improving the envelope represents the basic requirement when undergoing a renovation project and, to achieve NZEB targets, advanced functionalities are required for this element that should go beyond current passive thermal barrier to become an active element (integrating energy harvesting, storage and distribution technologies).

 

This improved renovation process must leverage advances in ICT, digitalization, automation  and robotics of industry to overcome the lack of a comprehensive approach to encompass current technologies and to facilitate communication between potential users and technology developers.

 

ENSNARE will boost the uptake of novel and highly efficient solutions for NZEB renovation via comprehensive methodology, tools and technologies that will accelerate the current renovation rate.

About Ensnare

The main goal of the ENSNARE project is to boost the implementation of NZEB renovation packages in Europe, with a focus on residential buildings. To accomplish this objective, the project develops two main technologies: Building components and digital solutions. The deployment of these two is founded in two key structures developed within ENSNARE: (see Figure):

  1. Envelope mesh, fully modular and based on industrialized principles, enables fast assembly and interconnection of all components and energy/data networks, including technologies for energy harvesting, storage and distribution. 
  2. Digital platform provides a framework to stakeholders with a clear structure and access to a wide range of technologies for deep renovation of buildings. It supports all stages of the renovation, from early decision making and data acquisition to the manufacturing, construction, and the operation and maintenance of the implemented system. The platform makes use of a digital toolbox (i.e., modular tools) closely linked to a digital model of the buildings, which in its final stage become a Digital Twin allowing real-time control, simulation and operation of all building components.

 

Within a comprehensive systemic approach and the above 2 pillars, the project will develop:

  • Modular adaptable components to be integrated within the system, including an active window for ventilation and heat recovery, solar harvesting devices (thermal collectors, PV and hybrid panels with advanced technologies such as roll-bonding), heat pumps and energy batteries for load shifting. 
  • A set of digital tools that will connect to the digital platform to support and accelerate all stages for a more efficient and automated  renovation process: automated data acquisition, LCA/LCC analysis and decision support, digital BIM model building and computer-assisted manufacturing (CAM), and a smart building management system (sBMS) for optimised operation and maintenance. 
  • Digital Twin that starts as a simplified digital model and increases in complexity and interaction potentialities as the project develops. At completion, the model becomes a Digital Twin of the renovated building allowing real-time monitorization, simulation and optimised operation of all building components.  

Consortium

Our Identity. Logotype and acronym

Our logo is composed of a modular envelope represented by the main body of the graphic which is defragmented, representing the digitization process of the information, this logo reading can also be done in reverse, where the digital fragments are reconstituted in the modular envelope. On the other hand, at the bottom, we can find the ENSNARE acronym built from the title of the project ENvelope meSh aNd digitAl framework for building REnovation “ENSNARE”.

In the English language, the word “ensnare” is a verb that means “to catch or control something or someone”. In line with this and the fact that one of the main objectives of the project is to develop an envelope mesh capable of “ensnare” information on the energy behavior of the building.

Who we are?

ENSNARE is Horizon 2020 EU funded project carried out by 19 partners from 12 European countries: 11 SMEs, 5 institutes of research, 2 Corporation, 1 public body.

PILOT SITES

The ENSNARE solution will be validated through 3 pilot renovation projects covering Nordic, Continental and Mediterranean climates, and 3 virtual demonstration buildings aimed at upscaling the development of the solution. These demonstrators have been selected to show the replication possibilities of the project, mostly in terms on advanced and improved retrofitting activities. The buildings have been chosen to represent the largest European construction residential market in different climatic conditions (Estonia, Bulgaria and Italy for Demos and UK, Italy and Netherland for the virtual ones) and different architectural implementations. The adoption of different seized buildings (~ 500 m2, ~ 1000m2 and ~ 3000m2) to be renovated with a different level of previous energy consumption level (80 – 200 kWhm2) allows to test and scale up procedures aiming to provide relevant inputs to study the industrialization, mass production and economy of scale based measurements to be adopted.

Tartu, Estonia

façade 442 m2, 26 windows, 10 dwellings 

Tartu pilot is situated in North-East of Tartu in Annelinn district. The pilot is a 2-storey residential used as a rehabilitation center for the ex-convicts. The goal for Tartu is to fully renovate the facility to provide a higher level of services and living conditions for men and women re-entering the society. The center will house up to 16 inhabitants in 8 apartments, include a security room, staff room, a meeting and service room and laundry room. The goal is to provide the risk group with stabile and high quality living conditions enabling a smooth transition into open society. The building will be renovated into near-zero energy building to minimize the building running costs for the NGO providing the social transition service for the inhabitants and the city.

Sofia, Bulgaria

façade 471 m2 , 42 windows, 6 dwellings, 80-100 kWh/m2 year

The pilot site in R. Bulgaria is located in the Boyana neighbourhood of Sofia – the capital of Bulgaria. The demo-site is a two-floors multi-family apartment building that was completed in 1974. In 2004, a total renovation was conducted and new part was added to the building. It has been continuously inhabited throughout its whole lifespan, currently, by four families. The building had been designed to have a total of 6 apartments on 4 levels, 2 on each floor. Throughout the years, some of them have been combined into separate habitations. Total floor area is approximately 560 m2. Additionally, there is a heated semi-basement, an open terrace on the last floor, connected to the central staircase. The roof is mostly flat and exposed façades oriented towards South-East and South-west. The total area of the facade is 471 m2. The building has a total of 42 windows, with an average annual energy consumption of 80-100 kWh/year.

San Demetrio, Italy

façade 942 m2 , 58 windows, 7 dwellings, 180-200 kWh/m2 year

Glasgow, UK

façade 980 m2 , 100 windows

Amsterdam, Netherlands

office building to be renovated as residential. 700 m2 , 80% glazed

Milan, Italy

façade 3100 m2 , 144,91 kWh /m2 year
