Energy efficiency (i.e., the ratio of output of performance to input of energy) in office buildings can reduce energy costs and CO 2 emissions, but there are barriers to widespread adoption of energy efficient solutions in offices because they are often perceived as a potential threat to perceived comfort, well-being, and performance of office users. However, the links between offices' energy efficiency and users' performance and well-being through their moderators are neither necessary nor empirically confirmed. The purpose of this study is to carry out a systematic review to identify the existing empirical evidence regarding the relationships between energy-efficient solutions in sustainable office buildings and the perceptions of employees' productivity and well-being. Additionally, we aim to identify relevant boundary conditions for these relationships to occur. A systematic literature search of online databases for energy efficiency literature (e.g., Environment Complete, GreenFILE ), employee literature (e.g., PsycINFO, Business Source Complete ) and general social science literature (e.g., Academic Search Complete ) yielded 34 empirical studies. Also, inclusion and exclusion criteria were set. The results suggest that it is possible to decouple energy costs from organizational outcomes such as employee well-being and performance. Also, they indicate the existence of moderators and mediators in the relationship between green office building solutions and well-being/performance. Directions for future research and the implications for practice considering different stakeholders interested in implementing green building solutions, adopting energy-saving measures in offices, and improving employees' functioning are suggested.

Successful design and construction processes aiming towards nearly zero energy building (nZEB) standards are a challenge for the whole construction industry in Europe. Realizing nZEB buildings requires innovative design processes, and technologies based on an integrated design approach facilitated by multidisciplinary work teams. The collaboration between architects, engineers, technical experts and building managers, is essential. Therefore, it is necessary to identify the specific involvement of each profession in order to develop mutual understanding of each others' disciplines. Additionally, it is vital to provide professionals with the skills needed to achieve optimal nZEB construction and retrofitting in terms of quality, energy efficiency and cost effectiveness. However, this approach is not yet common, as the building sector is still very fragmented. The EU-funded H2020 project PROF/TRAC aims to tackle this issue by developing an Open Training Platform and a methodology for fast and valid co-creation of interdisciplinary qualification schemes for task-based Continuous Professional Development (CPD) for all professions involved. A common methodology for the mapping of skills and qualifications in the form of an Excel tool was developed as a basis, together with a guidance document. This paper presents the skill-mapping methodology, the use of its results to develop national roadmaps, and the BUILD UP Skills advisor app.

Estudios previos han investigado la influencia de la calidad del ambiente interior (CAI) de las oficinas en el bienestar, salud y rendimiento de los empleados. Sin embargo, no parecen haberse explorado explícitamente cuáles son las condiciones ambientales apropiadas para los diferentes patrones de trabajo que conviven en estos espacios. Este artículo presenta los resultados de un estudio empírico, basado en mediciones sincronizadas de diferentes parámetros CAI (i.e., ruido, iluminación y temperatura), y el bienestar, la salud y el rendimiento de 71 empleados ubicados en doce espacios de oficinas de la Comunidad Valenciana durante tres periodos, considerando invierno y verano. Estos resultados referentes al primer invierno monitorizado, sugieren la existencia de diferentes parámetros óptimos asociados a diferentes niveles de complejidad de la tarea para el clima mediterráneo; y abren nuevas vías de investigación para establecer un modelo de Oficinas Inteligentes y Sostenibles (SSO) y desarrollar herramientas de apoyo al diseño y la gestión de las mismas.

The ALDREN project (ALliance for Deep RENovation in Buildings) is the extended development and the implementation of a common European Voluntary Certification Scheme (EVCS) for non-residential buildings based on the EPBD Art. 11 (9) and CEN / ISO standards. ALDREN is a coordination and support action (CSA). It focuses on existing tools and schemes (partly developed by the European Commission), on networking, standardization, awareness raising and communications. The main goal of ALDREN is to encourage the construction sector value chain stakeholders to undertake deep renovation projects on their properties. Issuing completed and verified Energy Performance Certificates (EPC) before and after renovation, are to contribute to the development of innovative financial valuation of building assets and financing instruments (e.g. integrating loans with differentiated interest rates) and establishing business case for deep renovation to motivate private investment. The core objectives of the ALDREN project are: • To provide a harmonized European energy performance rating methodology based on the European Voluntary Certification Scheme (EVCS) verified by measurements to increase comparability, confidence and market uptake by standardized solutions (CEN/ISO standards) at European scale; • To associate low energy renovation with high quality indoor environments to trigger renovation and to promote solutions supporting health and well-being; • To align market recognition of high quality with enhanced building value and capacity building. The ALDREN overarching outcome will be the infrastructure to enable market transformation for deep renovation and directly support the EU policies (EED, EPBD). Specific solutions and step-by-step renovation process will be integrated in a consistent, common way in a Building Renovation Passport (BRP). The ALDREN BRP will be aligned with the GABC (Global Alliance for Building and Construction) Building Passport initiative, seconded by DG Grow and DG Environment and with the current initiatives for residential buildings. The non-residential sector (office buildings and hotels) is to be considered as a first step. To demonstrate the ALDREN approach , the upgraded EVCS will be implemented in pilot office buildings and hotels in different climates over the European territory. However, the ALDREN approach could be adapted to other market sectors, in a further development. ALDREN renovation protocols may be used as individual modules in existing schemes or as standalone tool, being potentially overtaken by Member States of the European Union.
