A successful design and construction process for NZE buildings and renovation requires to follow an integrated design approach and to work in multi-disciplinary teams. However, this approach is still not common PROF-TRAC offers a solution for this barrier by developing and maintaining an education platform for dedicated trainings and continuous development for professionals, i.e., both technical experts as architects, in integrated multi-disciplinary approach for nZEB principles, in a Post Graduate qualification/curriculum. PROF-TRAC has the following objectives: 1. Mapping of the required skills and current skills gap of professionals in NZEB. 2. Development of an open training platform including methods for a systematic and sustainable access to knowledge. 3. Development of a Train the Trainers programme for the developed curriculum and/or qualification scheme This training programme will be tested on a national scale in six national pilots and on an international scale by a train-the-trainer program provided by two EU umbrella organisations representing engineers (REHVA) and architects (ACE). 4. Development of a repository of the training material for use in education and post-initial education PROF-TRAC is specifically targeting the need to train architects, engineers, building managers and other building professionals in the necessary skills for designing, constructing, managing and operating NZE construction and retrofitting. The proposed approach will lead to a substantial reduction of skills mismatch for professionals, Increased managerial capacity to support innovation and sustainable energy use in buildings through new leadership, design, construction and management skills for professionals at middle and senior level and fostering of a better cooperation between disciplines. PROF-TRAC is building upon previous IEE projects (BuildUpSkills, IDES-EDU etc.) and is initiated by the largest European associations for the sector (REHVA, ACE, CECODHAS).

ENERFUND is a tool that will rate and score deep renovation opportunities like a credit score used by banks to rate clients. The tool will be based on a methodology to be developed and on a set of parameters such as EPC data, number of certified installers, governmental schemes running, etc. By providing a rating for deep renovation opportunities whether for private establishments or for public buildings funding institutes can provide targeted loans, retrofit companies can identify sound opportunities, municipalities can promote targeted incentives and the publics trust for retrofitting will be enhanced. The objectives of the current proposal is to (a) analyse the status quo and needs of deep renovation stakeholders and the public, (b) build upon the outcomes of previous projects to create a tool for deep renovation financing, (c) promote the tool to all interested stakeholders, (d) measure and document the impact of the tool on deep renovation strategies and financing and (e) provide a powerful tool that will assist EU stakeholders meet their obligations on increasing renovation rates. The partners, from 12 countries, include 2 universities, in charge of the project management and the development of the methodology behind the tool, 2 SMEs with extensive experience on database management, EPC mapping, development of online decision-making tools, and 11 Ministries, Energy Agencies, NGOs, etc that are connected with the relevant stakeholders throughout Europe and can promote the tool. The expected impact is approximately 45GWh due to the use of the tool to promote deep renovation of buildings and through our training and dissemination activities. ENERFUND will account for approximately 1% of the current annual renovation rate during the project duration. The strategic, long term aim is to provide a unified global tool for the promotion, not only of deep renovation of buildings, but of all energy related activities in the building sector.

Recent studies reveal physical, economical, and socio-technical barriers when measuring performance of sustainable urban ration projects with existing assessment tools. This reality, enlarged in the Spanish context, has revealed the need of a friendly-user and holistic tool that can assist the agents involved in the decision-making process of urban regeneration projects. This paper presents the Guide of strategies for urban regeneration; a design-support tool developed by demand of the Government of the Valencian Community (Spain). Along this paper we describe how the Guide has been designed by integrating: in first place measures of exiting urban assessment tools, secondly lesson learned coming from the application of urban assessment tools to selected and rewarded urban best practices at European level, and thirdly the opinion of regional decision-makers and urban experts. As a result, this Guide offers strategies and recommendations on a self-questioning format that makes easy its implementation by any urban planner regardless of its expertise on the topic. It is based on an open-source philosophy with a nonprofit orientation, using transparent and easy-to-understand technical criteria. It can be applied to any kind of urban fabric and proposes equal representation of the thematic categories needed to be considered during an urban regeneration project design. © 2015 Elsevier Ltd.

A popular method to obtain the 1-D conduction heat transfer of multi-layered plane geometries is attributed to Stephenson and Mitalas (1971) and Mitalas (1968). It is applied in different forms known as; CTF (Conduction Transfer Functions) or RT (Response factors). Roughly his idea consists in sampling the temperature at each side of a wall at a certain fixed time step (usually one hour). Between sampling points, due to the lack of information, a linear profile for the evolution of those temperatures is imposed. A triangle shaping function is used to get such a piecewise linear profile. The method although is powerful, has passed through the years without questioning. The paper proposes an improvement by extending the idea of a shaping function. Instead of assuming a linear evolution, a specially designed second order (parabolic) evolution is enforced. Now, two parameters must be determined to define the temperature shape between sampling points at both sides of the wall; on one side, the new values of the temperatures and on the other, their acceleration within the time step. Contrary to Mitalas, now two equations are needed at each side to determine these new shapes; the heat power flux balance at both surfaces at the new sampling point (like in Mitalas' method) plus the thermal energy balance along the period of time between sampling points. This turns the scheme into an energy conservative one. Finally it is shown that the accuracy obtained by the parabolic case at one hour of sampling rate is similar to the linear case with a sampling rate of five minutes. © 2015 Elsevier Ltd.

Vernacular Architecture: Towards a Sustainable Future - Proceedings of the International Conference on Vernacular Heritage, Sustainability and Earthen Architecture | Year: 2015

The Cabanyal-Canyamelar district of Valencia, in contact with the Mediterranean Sea, has a heritage value recognized in 1993 when it was declared a place of cultural interest in the historic-artistic category. However, the area has a significant level of deterioration and it is urgent to enhance regeneration actions, especially for the buildings go heritage value. This paper presents the conclusion reached from a study developed about the energy performance of vernacular architecture in this neighborhood. Finally, it concludes that their traditional construction presents good behavior that complements perfectly the Mediterranean climate in which it is located. It has also been found that the building types have a potential to support future renovations, compatible with their heritage value, and also give value to the bioclimatic quality of the historic buildings in the neighborhood. © 2015 Taylor & Francis Group.

In the last decade, several schemes for assessing and certificating the sustainability have been developed to guide urban regeneration projects. However, recent studies suggest that the underuse of these tools may be due to their biased results. This paper therefore takes as a starting point the essential tenet that these tools are too focused on estimating the environmental impacts and have partially reflected other important aspects such as the economic impacts. A key topic should be promoting a scenario where urban regeneration is identified as an economically viable initiative that generates added value and innovation. This is one of the main goals of the Eurbanlab project. Consequently, this paper focuses on the Profit indicators which add a differential value to other certification schemes and compares five case studies rated by the B4U Eurbanlab assessment tool. © 2015 Taylor & Francis Group.

The estimation of the service life of the construction elements of a building and its materials is an essential part of drawing up a realistic and economically viable maintenance program. In this regard, this paper presents a methodology to estimate the service life of the construction systems of outer walls and roofs frequently used in modern buildings. The reference document used was the ISO-15686 standard, which proposes an efficient method of estimating service life based on durability factors. However this method was designed for general application and is difficult to apply. Due to the scarce amount of reliable information available on material durability values, it was found necessary to generate a service-life database of the construction elements considered, as well as of their component materials, based on their common degradation mechanisms. Factors that affect durability were also identified and a clear procedure for evaluation was set up. The proposed method, rather than giving accurate information on service life, allows different construction systems to be compared and is thus of assistance in the project design phase. The methodology can also be used as a model for other construction elements and is transferable to other countries.

The Spanish residential building stock built between 1940 and 1980 period presents a high energy saving potential as it represents a significant percentage of the total housing stock and it was built without any regulation regarding energy efficiency. Accordingly, the first aim of this paper was to quantify the energy saving potential and the related reduction in CO2 emissions of the housing stock in those years. The work focuses on the Mediterranean climate of the Comunitat Valenciana Region, therefore the energy efficiency strategies proposed are passive and deal with the envelope of buildings. On the basis of the results obtained, several scenarios with intervention periods of 10, 20 and 30 years were calculated. The conclusion was that with the current rate of annual building renovation, it will be nearly impossible to reach the goals established by the EPBD. Only a deep transformation of the building fabric within this sector could help in achieving them. Finally, it should be noted that the proposed methodology can be applied to other areas with different climates, particularly in Spain. © 2016 Elsevier B.V.

The estimated service life, as well as its components materials, is critical in order to establish realistic building maintenance programs, manageable and economically viable. The methods based on durability factors, proposed in ISO- 15686, are an efficient way of estimating the building's service life. However, there has been limited information on quantifying the durability values, and their relationship to vulnerability or processes of deterioration which might present a constructive element. Then, this paper describes a method to characterize the most frequent damage mechanisms in the envelope of a building, since it is an element with a high risk of lesions and, accordingly, with a reduced durability. The system used to generate this information was the Delphi method that involves consultation to groups with expert-based approach to generate convergence of views. The results allow the identification and quantification of relevant durability factors that determine the occurrence of damage to an element affecting its service life.
