MORE-CONNECT Report Summary

Project ID: 633477
Funded under: H2020-EU.3.3.1.

Periodic Reporting for period 1 - MORE-CONNECT (Development and advanced prefabrication of innovative, multifunctional building envelope elements for MOdular REtrofitting and CONNECTions)

Reporting period: 2014-12-01 to 2016-05-31

Summary of the context and overall objectives of the project

The challenge of MORE-CONNECT is to overcome current barriers to come to large scale deep renovation by applying prefabricated multifunctional renovation elements. These elements have the potential to reduce costs, reduce the renovation time and disturbance for occupants and, at the same time, enhance quality and performances (both in terms of energy efficiency as indoor climate). The MORE-CONNECT project aims to make a major step forwards by a combination of product innovation, process innovation and innovative market approach, in a process of cost and quality optimization, driven by motivated and innovation-driven SME’s.
The overall objectives of MORE-CONNECT are:

1. The development of cost optimal deep renovation solutions towards nZEB concepts with the possibility of extra customize (cost-effective) features
A number of optimal configurations will be developed for nZEB renovation concepts. These concepts will be preselected, i.e. in balance between demand reduction and renewable production, looking for the most optimal mix within the range of term ‘nearly’ in Nearly Zero Energy. Next to it, a life cycle approach will be used to assess the modular renovation solutions.

2. The development and demonstration of prefabricated multifunctional modular renovation elements in series of 1 concepts, in a mass production process
Platforms will be developed and demonstrated for prefabricated, multifunctional renovation elements for the total building envelope (facade and roof) and installation/building services. These elements can be combined, selected and configured by the end-user, based on his specific needs. The configuration can be made on the basis of a pre-selection of elements, based on the specific properties and measures of his home inventoried by advanced geomatics with various aesthetic and architectonic appearances. As input into advanced Building Information Modelling systems it can control and steer the further production process of these elements. In this way unique series of one can be made in a mass production process for the same reduced price of mass production.

3. The development and demonstration of new fully automated production lines for multifunctional modular renovation elements
New designed automated production lines will be developed that effortlessly support line production that is effective on series-1 as well as large series and seamlessly combine into mass customization principles; aimed at supporting prefabrication for extreme retrofitting of homes.
Extreme automation makes it possible to produce end-user-defined (by choice) integral products efficient in small (1) as well as large series. Machine instructions then need to come from automated computerized numeric control instruction generation based on Building Information Modelling BIM and in-situ measurements. Plant management is organized in software solutions that support line-balancing as well as JIT (just in time) and flow. Line design needs to support scalability in product complexity, support of more than one product-market combination and output. This will lead to a blueprint for the design and structure of a platform for a fully automated production line, as a further basis for product-market-combinations in several countries. In MORE-CONNECT it will be demonstrated that a model for one common platform for a fully automated production line can be used in different geo-clusters.

4. The offering of a one-stop-shop to the end-user to renovate their homes
A one-stop-shop concept will be developed or the end-user, but also for the production. In this ‘one-stop-shop’ proposition the end-user will deal with only one party, responsible for the total renovation, starting from an inventory of the existing situation, inventory of specific end-user demands, translation into modular renovation kits, mounting and installing, financing and aftercare. The high level of prefabrication and the use of smart connectors (mechanical, hydraulic, air, thermal, electrical, ICT) will limit the actual renovation time on site to a maximum of 5 days with a goal for an average of two days, including the complete or partial removal of the existing facades and roofs or other elements. During the renovation the occupants can stay in their homes and have a minimum disturbance. The end-users will get a guaranteed energy cost proposition for their renovated homes, based on their individual household profiles. An energy cost and performance guarantee is possible by the high level of quality control during the production process and the monitoring of performances of the most essential parameters related to energy use (ventilation, heating, indoor air temperature, micro climate conditions, electric appliances etc.) and remote diagnostics of the most important installations and building services.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

"Work package 1 Management and coordination
Objective of WP1 is to provide the organisational infrastructure and management of the project, necessary to operate the project and to perform all administrative, financial and operational tasks, directly related to the co-ordination of the project.
The project secretary was already in place before the start of the project.
The project website has been launched three months after the start of the project. Instead of the ‘members only’ section it was decided to use dropbox for easy and low threshold sharing of documents. This dropbox is also shared with the EASME.
During the first reporting period following meetings have been organized:
Regular working meetings:
Meeting 1: January 12 and 13, 2015 Prague, CVUT and UCEEB, Czech Republic
Meeting 2: September 22 to 24, 2015, Maastricht, The Netherlands
Meeting 3: January 28 and 29, 2016, Guimarães, Portugal
Special workshops:
Workshop 1 Technology development, May 6 and 7 2015, Riga, Latvia
Directly after the start a Consortium Agreement was devised based on the DECSA model.
MORE-CONNECT originally foresees a Project Advisory Board. This was filled slightly different by collaboration with three important and relevant European umbrella associations: REHVA, representing the HVAC engineers branch, Architect’s Council of Europe, representing the architects branch and Housing Europe, representing the federations of social housing associations. Reason for this was that these branch organisations are participants in the H2020 Construction Skills project PROF/TRAC, also coordinated by Huygen IA, which offers a quick and efficient collaboration and consulting on a regular basis as feedback on annual meetings. In the Netherlands, a strong collaboration is established with the Dutch Governmental Programs Energiesprong and Stroomversnelling, by partner BJW. This collaboration provided input for work package 6.

Work package 2 Technology development
The modular building envelope’s retrofitting elements decrease most of all heat loss through the building envelope that is usually the largest component in energy use of old residential buildings. Nevertheless required properties for the modular building envelope’s retrofitting elements may depend on specific building and balance of measures for energy saving and energy production on site. Therefore in Task 2.1 it was analysed what kind of requirements exists for modular elements to meet following targets for nZEB, 80% reduction and ZEB.
The objective of Task 2.2 is to develop basic modular elements for façades and roofs. The development until M18 was focused on collection of requirements on the renovation packages from all geoclusters. From this information were derived overall requirements on the wall modules. There was developed a decision-making tree, which helps to determine the dimensions and shapes of wall modules and location of connections of the integrated building technologies.
Development of the universal basic wall panel started in M12 and the actual state was presented and discussed with experts within the focused session of MORE-CONNECT at the international conference CESB16 Prague.
Task 2.3 “HVAC solutions” provides technology inventory and review of all components that are necessary to climatize the buildings. The main challenge of this deliverable was to define HVAC systems’ dimensions and design specifics in four European geoclusters. The report “HVAC solutions” focuses on the ventilation systems and energy units. The integration of embedded ventilation systems is a major challenge for practical application of prefabricated panels. In the scope of this task, the analysis of ventilation systems’ design in the project countries was performed and main design parameters, such as necessary air flow, duct diameters and air velocity were defined. The SWOT analysis made for different types of ventilation systems provided a clear guidance for selection of most appropriate ventilation systems taking into account buildings’ construction, maintenance as well as operation costs. In addition, the technical solution for modular HVAC units has been provided. This deliverable is based on the survey done in each project geocluster and practical calculations taking into account the information submitted by partners. The installation and the maintenance costs were calculated using standard catalogues.
The specific objectives of Task 2.4 were to develop the state-of-the-art of building integrated renewable energy technologies, the overview of the technical/social barriers as well as the political context, at the global and local level, regarding the integration of renewable energy production in buildings. UMinho performed an extensive literature review in order to identify and describe the most up-to-date building integrated renewable energy technologies available (solar photovoltaic, solar thermal, wind, biomass, geothermal), including real case studies. The work carried out by UMinho also addressed a detailed list of the technical/social barriers and description of the political context at the global level. Each project participant then detailed the specific barriers and political context for its geo-cluster. Moreover, each geo-cluster characterized its pilot case (climate analysis, space availability) to enable a future optimization of the most suitable renewable energy technologies to integrate. The objectives of this task were achieved during the reporting period and resulted in a completed report Integration of Renewables. Technology Overview (D2.4, MoreConnect_WP2_2 4_Final.pdf).
Drying out of constructional moisture of original walls and roof structure could bring significant moisture load on prefabricated panels. This is assessed in task 2.5 by dynamic hygrothermal simulation. First the potential of moisture dry-out from concrete wall was analysed using validated calculation program and calibrated calculation model for a long-term period (1970-2012). The analysis showed that the hygrothermal performance of concrete wall is most dependent on constructional moisture content, dry-out capability and wind-driven rain load as well as on the N-E-S-W orientation of the wall. The results showed the highest moisture content in the wall’s external concrete slab on south-west direction in the last quarter and the first months of the year, when the moisture content was 110-114 kg/m3. The study showed that in the design of highly insulated concrete walls in cold and humid climate it is important to properly evaluate the initial state of constructions and consider critical weather loads in order to determine the feasible hygrothermal performance. The hygrothermal performance of the envelope was evaluated with calibrated dynamic hygrothermal simulations and with a mould index model. The calculations were made to evaluate the hygrothermal risks in the building envelope and after the prefabricated modular elements were installed, the focus was on studying concrete wall’s dry-out capability and the use of vapour barrier. The initial moisture content of the concrete wall and a right choice of air & vapour barrier layer has considerable impact on the entire envelope performance. Results showed that in the renovation of prefabricated concrete large panel buildings, it is possible to achieve good results and build sustainable solutions according to up-to-date requirements of nZEB in a cold and humid climate.
Task 2.6 was focused on preparation of the smart connectors and draft report. The draft report describes ways of connectors solutions in structural part, statics part, HVAC part, electrical part and IT part. Report is continuously updated and actualized with respect to connectors solutions for different building types and different conditions. In structural part, overall appearance of the building and physical properties of the building envelope are solved, while support elements and fastening elements solutions are described in statics part. HVAC part primarily focuses on combination of quick assembly and connector durability as well as space heating and ventilation solutions. Electrical and IT part solves electricity and IT distribution integrated in the façade. Differences in structural solutions have major impact on connectors solutions.
Task 2.7 was during the reporting period mainly focused on following areas:
1) Approach and algorithms for optimal usage of locally generated RES energy. The effort was connected with advanced simulations of the renewable energy sources integrated on the roof and facade retrofitting modules. The simulations of energy generated and used were carried out for Czech More-Connect case studies. Three energy system architectures were defined including various control algorithms covering systems with and without energy storage as well as partially controlled load approach.
Renewable energy sources forecasting service. Literature review was carried put in this field and according this review the main aspects of RES forecasting were identified. PV-Forecast web service was introduces as a part of the energy flow control algorithm and currently it is tested in the Czech Republic. The input of this service to energy flow control algorithms is currently tested in UCEEB.
Advanced controls and monitoring systems. The work related to this particular topic included development of indoor environment quality sensors and their connection to the control systems. This development still continues and first prototypes are expected in coming months allowing wired as well as wireless communication interfacing. Other works are related to sensors systems for continuous diagnostics of the timber structures with respect to moisture (System MoistureGuard). Development in this area still continues and first pilot applications are already running and data are continuously evaluated.

Work package 3 – System Integration
Task 3.1 Typology of building stock for relevant market in the Geo Clusters is concentrated on developing a common typology analyses of buildings types in the divers geoclusters. At first the most common building types in each cluster were determined. Next these building types were analyzed for their core features, to learn what the basic building technology has been during construction, and from there analyses what could be the bare construction suitable for a prefab panel retrofit .Once these common and different features of each geocluster are documented, it is clear what elements can be jointly developed and which need local adaptation. In this workpackage a matrix is developed that classifies building types and common features in each geo cluster, as well as providing the specifications for development of prefab elements
Building on the results of wp 3.1 intask 3.2 Modular Concepts: development and design selection the work started to define a optimization approach for detailing the prefab facade elements. Analyses has been carried out for different type of load bearing structures, ways of connection, and physical performance requirements, as for instance securing air tightness operation during installing of elements . This task also studied the material impacts of prefab elements, ie the insulation package , in terms of embodied energy impact , decreasing the operational energy savings. A study is made of different insulation levels compared with accompanying PV levels to make the retrofitted house a 0-house. O-energy is chosen as the reference, since at that point operational energy has no CO2/fossil fuel impacts anymore, and the CO2/fossil fuel impacts from materials invested become decisive. The 80 % reduction situation can then be established by installing less PV panels, with the advantage that in future when the 0-energy situation is required, the building is already optimized for that. From the findings recommendations are made for materialization of elements. In 3.4 this is further developed into a decision tool. D3.2 Tool to optimize the combined energy and materials performance of the alternative configurations in relation to local typologies – month 20, the report is in preparation
Task 3.3 Modular Concepts platform development concentrates on developing a Platform for retrofit concepts, using the findings and analyses form other work packages in the technical detailing of prefab facade models. The platform should give easy insight in modeling a concept, the available freedom in choices of facade elements, and act as basis for tor descriptions of real market retrofit concepts. The work has started this spring.
In Task 3.4 Performance criteria assessment of concepts a standard analyses method is developed, based on integrated energy and materials performance assessment. This will provide a easy and standard way of analyses of detailing the develop concepts. The methodology will be further developed to included technical and cost related references, to make both a environmental, technical and cost optimization, and explore the differences, to guide choices. The work has already started in conjunction with task 3.2
Task 3.5 Life cycle Assessment of concepts goes one step deeper in the analyses and assessment, as in 3.2 and 3.4. The methodology is based on the comprehensive assessment of all energy, GHG-emissions and cost impacts resulting from MORE-CONNECT solutions. It includes embodied energy use and related GHG-emissions for the materials. The draft methodology report was discussed with the leader of WP3 and coordinated with the work on performance criteria in Task 3.4. The methodology is also used for the pre-selection of favourable concepts in Task 6.1, for the pilots in WP4 and for the final selection of favourable concepts.
Task 3.6 Performance Monitoring and Control of Integrated Systems started in M18. The first step is collection of requirements on short-term and long-term monitoring systems. The short-term monitoring systems will be used for the experimental elements, whilst the long-term monitoring and control systems will be designed in variants for the final renovation packages.

Work package 4 – Production and Process
Task 4.1 concerns the application of advanced geomatics is investigated and developed to be embedded as the first step in the total automated production process. CVUT developed state-of-the-art of the applicable methods, as the first step of buildings reconstruction. A report is completed with an overview of geomatics techniques that can be used for building reconstruction and to show advantages of their integration into different project phases. It provides information to civil engineering companies in order to be knowledgeable in the field of geomatics. Better understanding of geomatics techniques and methodology will lead to more exact specifications of project requirements for surveyors and also to cost optimization of the geomatics work (surveying, processing of data and information transfer into desired software in appropriate format). Described are mainly the following methods:
• Laser scanning
• Digital Photogrammetry
Task 4.2 concerns the modelling of the building characteristics and options, based on the data following from task 4.1 and the modelling of the end-user profiles in terms of end-user requirements and favourable configurations of the modular renovation concepts by the end-users. A flow scheme of the steps to make in the programme has been developed.
Task 4.3 focuses on a seamless integration of BIM with integral computerized numeric control production in which BIM is aimed at construction, not at production/fabrication
RTU developed detailed state-of-the-art report of the problematic BIM. Currently a draft report ‘BIM application’ is devised.
Task 4.4 will lead to a blueprint for the design and structure of a fully automated production line, integrating and connecting the developed technologies from tasks 4.1, 4.2 and 4.3 This wil
l be the further basis for product-market-combinations, the business cases and one-stop-shop concepts in work package 6. The work on task started in M14. Currently, we solve the problem of transfer of BIM in the manufacturing process.
Task 4.5 concerns the quality control and quality assurance of the process. Work on task started in M14. Work continues on task 4.4.

Work package 5 – Pilots in Geo Clusters
The objective of this work package is the testing, pilot implementations and demonstration in real settings, as well as in industrial settings (demonstration of production), as in practice (demonstration and testing of the developed modular renovation elements both in real settings as in real life learning lab (RLLL) settings.

Task 5.3 Production of the prototypes of the prefabricated elements
Prototyping in Mateks’s factory

Task 5.1 Preliminary and preparation works
For the pilot project selected by the building association the preliminary work with respect to getting approval from the boards of the building association itself and that of tenants of the buildings selected for the pilot. However, because of change of position of the driving person in charge of the renovation process at the building association to another building association in Denmark - KAB - one of the largest buildings associations in Denmark the pilot project has to be selected among the properties administered by KAB, as the first building association did not want to keep the project. The work to identify a new pilot project is now undergoing and will be completed in July 2016. After that the preparation works will start immediately to avoid any delay.
Task 5.2 Preparation of technical documentation
Two workshops have been conducted with participants representing a contractor – NCC – the building association, the two Danish producers within the MORE-CONNECT project – Invela and Innogie and Cenergia as the advisor of the building association and as coordinator of the workshop. During these workshop the whole renovation process has been discussed and planned aiming at the best possible integration of the products of Invela and Innogie. This work can be continued with the new pilot project and will thus be a good starting point for a quick renovation process..
Task 5.3 Production of the prototypes of the prefabricated elements
Invela has identified the most suitable material for the automated process of adding an insulations layer and finishing on existing facades and Innogie has produced several prototypes of both their PV and PVT roofing elements.

Czech Republic (RLLL setting for in deep testing)
The pilots in Czechia will take place in experimental setting at UCEEB.
Task 5.1 Preliminary and preparation Works:
The preliminary works within in T5.1 were focused on selection of details that need to be tested. We plan to build a mockup of a bulding section of a typical building – corner including details of walls with windows, plinth and connections to roof structure. Structure will be made of full bricks (as typical) and on the structure will be applied testing modules.
Task 5.2 Preparation of technical documentation
The preparation of detailed technical documentation will start in M22 as planned in teh project.

Task 5.1 Preliminary and preparation works
At the moment we have not yet started to prepare works on site, rather than the monitoring of the pilot building (energy performance and indoor environmental quality in general). The necessary documentation will be prepared within the foreseeable future, with the upcoming development of the elements for renovation and the end of the monitoring process (end of 2016).
Task 5.2 Preparation of technical documentation
The prefab modular elements are still in development. Advanced geomatics will be used whenever possible.
Task 5.3 Production of the prototypes of the prefabricated elements
The first version of the prefabricated elements has been produced and installed in the UMinho lab for testing. There are some problems mainly related with thermal bridges. Tests are still going on together with the simulation of the prototype with a dynamic simulation tool (ANSYS). New solutions are now being envisaged. In these circumstances, manufacturing of the prototypes has not yet started.
Task 5.4 Construction work
Construction work has not started yet. Development of the prefabricated elements is still taking place.

It appears that WP5 is well underway, although at different stages in the different geo-clusters. The first delivery date is in Month 24 for D5.1 and D5.2. No delay is anticipated. Also the realization of all pilots and RLLLs can be realistically completed according to the plan by Month 29.
WP5 and WP2 has during this first period co-operated on the documentation of the pilot projects in a standard format, see D2.1.
Cenergia has co-operated with Econcept in Work package 6 on testing the methodology for the calculations/evaluations leading to the pre-selection of the favourable concepts. This has resulted in an accepted paper for the for the SBE 2016 conference in Helsinki/Tallinn in October 2016: “Concept development and technology choices for the More-Connect pilot energy renovation of three apartment blocks in Denmark”.

Work Package 6 Market and Replication
First stage of task 6.1 is a pre-selection of favourable concepts which are to be developed and tested in the pilots. These pre-selections rely on results of Work Packages 2 and 3 and on assessments of the technical solutions developed. The pre-selection is performed with respect to initial performance criteria which have been determined for the pre-selection (see WP 3). It uses a common assessment methodology which has been worked out for this pre-selection as well as for the upcoming final selection of favourable concepts. The selection of favourable concepts will be done with a specific focus on each geo-cluster and the technical solutions developed for the five geo-clusters.
Collaboration of WP3 and WP6 with regard to performance criteria resulted in the definition of the following indicators, besides technical, energy, health, thermal, noise and air quality related indicators (see WP2), to be assessed for performance measurement. For the pre-selection of favourable concepts the following assessment procedure has been developed:
1. Definition of framework parameters: Economic parameters used in the assessments such as energy prices, interest rates and exchange rates, emission factors, primary energy factors and climate data etc. for the specific geo-cluster.
2. Definition of reference building and necessary building data for the assessment: Dimensions and energetic properties of all building elements having an influence on the energy performance and GHG emissions.
3. Assessment of the reference case: Determination of the «anyway renovation» measures for the reference buildings, of related service lives of the measures carried out as well as of associated costs, maintenance costs, and resulting energy needs of the building. Calculation of the impacts on primary energy use, greenhouse gas emissions and costs for the «anyway renovation» - reference case. The «anyway renovation» measures are measures which restore the full functionality of the building elements with renovation needs, yet without improving energy performance
4. Definition and assessment of different renovation packages with MORE-CONNECT-solutions: MORE-CONNECT measures are combined to renovation packages, starting with the most economical MORE-CONNECT solutions first. Related service lives, associated costs, maintenance costs and resulting energy needs of the building are investigated and assessed and the impacts on primary energy use, greenhouse gas emissions and costs for the renovation case with MORE-CONNECT measures are determined.
5. By comparing the impacts of the reference anyway renovation case with those of different renovation packages of MORE-CONNECT measures and with different heating systems on greenhouse gas emissions, primary energy use and costs, the effects of the MORE-CONNECT-solutions are illustrated and their favourability compared to a reference renovation can be demonstrated.
6. The impact of particular assumptions or input factors will be demonstrated by sensitivity calculations (e.g. with respect to energy prices or initial energy performance of the reference building).
7. Evaluation and selection: Based on these assessments, preselection of MORE-CONNECT-solutions for test-applications in the 5 geo-clusters will be carried out.
Preparations for assessing such renovation packages with MORE-CONNECT-solutions and possible variants have been started:
A template was developed defining data needs and facilitating data collection to assess the MORE-CONNECT-solutions in the 5 geo-clusters; the responsible partners have started gathering the related data. An important part of the data gathering activities is to gather such data for several variants of the particular MORE-CONNECT-solution; this allows to optimize between different variants for MORE-CONNECT-solutions per geo-cluster. According to the template, the following data is foreseen to be gathered by project partners for each geo-cluster:
Data on dimensions and characteristics of a reference building typical for the ones to be targeted by the MORE-CONNECT market concepts in the geo-cluster.
Data on hypothetical "anyway-renovations" that would typically have to be carried out anyway just to restore the reference building's functionality, yet without improving the energy performance of the building, including data on costs of such measures to assess the economic effectiveness of the actual renovation measures in comparison with them.
Data on different options for MORE-CONNECT-renovation measures. For each building element which is renovated, data on at least two different material options and for each of them two different efficiency levels are gathered, in order to create a variety of options based on which an optimization can be made.
Data on heating systems, hot water systems, and cooling systems, if applicable. Cost data for these systems need to cover a span of possible sizes of these systems, as the actual size and related costs depend on the level of renovation measures carried out on the building envelope
Embodied energy and embodied greenhouse gas emissions of the materials used in the specific variant of MORE-CONNECT-solution
A template for creating graphs was developed to illustrate the primary energy, GHG emissions and cost impacts of the investigated options for packages with MORE-CONNECT renovation measures to support optimization and selection of favourable MORE-CONNECT-solutions and concepts.
Task 6.2 Life cycle analyses of favourable concepts for each geo-cluster will start in the second half of the MORE-CONNECT-project.
Task 6.3 Business cases for the market concepts for each geo-cluster will start in the second half of the MORE-CONNECT-project.
Task 6.4 Models for a one-stop-shop concept including a system of performance control and guaranteed energy cost proposition will be predominantly carried out after month 24, but first draft proposals for one-stop-shop concepts and energy performance guarantees have been developed and implemented in the Netherlands by BJW Wonen. This happened well ahead of the planning according to the MORE-CONNECT project. This was possible due to participation in the Dutch Governmental Programs Energiesprong and Stroomversnelling. Other MORE-CONNECT participating countries where not yet involved.
BJW Wonen has participated in several workshops and in a pilot use of ‘Performance guarantees
for NZEB renovations’ combined with long term ‘Maintenance and support contracts’ (40 years) and ‘Monitoring’.

Work Package 7 Communication, Training and Dissemination
This work package is being actively implemented since the early beginning of the project. The project’s stakeholders have been identified at the initial stage of the project. Currently there are 76 stakeholders identified. The Project flyer was prepared on time and is currently disseminated among the stakeholders and during local and international events (conferences, seminars, meeting etc.).
Three intentional peer-reviewed open access scientific papers have been already published. Four more scientific papers are submitted to the scientific conferences which are indexed in the SCOPU"

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

- Integration of several technical components, corresponding with the function of the element in multifunctional elements; first façade element and ‘engine’ (prefab installation platform) developed by BJW for living lab house in Heerlen, NL. Two houses under monitoring now.
- Design of combined smart Plug&Play connectors (mechanical, hydraulic, air, thermal, electric and ICT)
- New combined methodology and tool devised to determine cost optimal configurations, related to energy use and embodied energy. Extension with IEQ parameters under investigation now.
- A new study showed that in the design of highly insulated concrete walls in cold and humid climate it is important to properly evaluate the initial state of constructions and consider critical weather loads in order to determine the feasible hygrothermal performance.
- The initial moisture content of the concrete wall and a right choice of air&vapor barrier layer has considerable impact on the entire envelope performance. Results showed that in the renovation of prefabricated concrete large panel buildings, it is possible to achieve good results and build sustainable solutions according to up-to-date requirements of nZEB in a cold and humid climate.
