Cost reduction ,NZEB ,Solution sets - Abstract
The main goal of the EU Horizon 2020 project CoNZEBs was to identify technology combinations for multi‐family houses that fulfil the Nearly Zero‐Energy Building (NZEB) requirements but result in lower investment costs if compared to the typical (mainstream) NZEB technology combinations. The national CoNZEBs teams from Germany, Denmark, Italy and Slovenia were successful in finding at least four alternative technology combinations(aka alternative NZEB solution sets) per country. These solution sets and many of the contained innovative technologies are described in detail in a report [1] available on the project website. In a second step the NZEB solution sets and a technology combination achieving a building energy level beyond NZEB (zero energy building or plus energy building) have been assessed in comparison to the typical NZEB and a building fulfilling the national minimum energy performance requirements regarding life‐cycle costs and life‐cycle impact[28].This report now seeks to look ahead into future developments of certain factors that have an impact on the energy performance, investment costs or energy costs of the determined solution sets. The relevant impact factors are primary energy factors, energy prices, technology costs and technology efficiencies. For each of these impact factors the developments by the year 2030 were predicted, based on available national studies or where not available based on the personal evaluation of the project partners.

Cost Reduction ,Low-energy buildings ,NZEB ,Solution sets - Abstract
Nearly zero energy buildings (NZEBs) are required as the minimum standard for all new buildings in Europe by January 2021. NZEBS should, according to the Energy Performance of Buildings Directive (EPBD) [1], be cost optimal, i.e. the cost of constructing and operating the building over its lifetime should be at its minimum. The EU Horizon2020 research project CoNZEBs, identify and assess technology solution sets that lead to cost reductions of new NZEBs in four EU member states. Focussing on buildings that comply with national NZEB requirements, designers can easily ignore alternative solutions that make the building cheaper while remaining within national requirements. This is not done intentionally, but primarily due to use of a traditional design thinking where optimisation is done on component level instead of a more holistic approach. Changing one building component may influence the cost and performance of other components. These alternative solutions take offset in a typical national multi-family building design and analyses the different lifetime costs in terms of costs for construction, and energy. Analyses of costs in different countries reveals different solutions sets being optimal. In CoNZEBs we compare different solution sets and investigate the possibility for “exporting” solution sets from one country to another.

- Abstract
This report presents the results of further analyses carried out for the solution sets identified in the previous work of the CoNZEBs project [1]. The solutions sets have been analysed to establish their life cycle costs (LCC) and life cycle environmental impact assessment (LCA). The solution sets have been assumed implemented for NZEB buildings and the results of the LCC and LCA analyses compared to those obtained for conventional buildings built according to current national building regulations (BR) (minimum energy performance requirements = min. EP), conventional built NZEB and buildings beyond NZEB (ZEB and plus‐energy buildings).

Cost reduction ,NZEB ,Solution sets - Abstract
Solution sets are collections of energy efficient technologies used in nearly zero‐energy buildings (NZEB) that in the specific case constitutes a building that meets the national NZEB requirements or beyond. A solution set may vary from one context or location to another and may include any number of technologies. Solution sets have the potential of reducing the cost of currently realised NZEB projects, i.e. a combination of technologies that support/supplement each other in striving towards NZEB at less investment cost. A solution set reduces the overall investment cost for a NZEB. This is achieved either by introduction of less costly solutions in general or by implementing combinations of cost and performance reductions in combination with other cost and performance improvements.

Cost reduction ,design process ,NZEB ,construction process - Abstract
Costs associated to energy performance of buildings are generally assessed taking into accounts purchase and installation of materials, components, goods of building and energy system technologies, without taking into account other issues that can significantly impact on the final construction costs. Such additional costs include: design, permits, urbanisation works, organisation and operation of the building site, preliminaries, insurances, final inspections and tests. Analogously, operation costs are generally limited to energy consumption for the different vectors, without taking into account the maintenance costs, whose percentage on total operational costs can be relevant in the long‐term, due to the small energy uses in NZEBs and to the complexity of building technologies and energy systems in high performing buildings.

Low-energy buildings ,NZEB ,CoNZEBs ,cost baseline - Abstract
This report documents the work of the CoNZEBs project on setting the cost baselines for different building energy performance levels. It analyses and compares the investment and energy costs in four different countries (Germany, Denmark, Italy and Slovenia) for: ⌂ New multi‐family houses built according to current national minimum energyperformance requirements⌂ Existing examples of NZEBs (nearly zero‐energy building) multi‐family houses⌂ Multi‐family houses that go beyond the NZEB‐levelThe work is based on literature on building costs, on the knowledge gained by the different research organisations and complemented by the cost experience of the national housing organisation. The work of Concerted Action EPBD on NZEBs is used as well. The result of these efforts is the starting point (baseline) for evaluating the technical solution sets for nearly zero‐energy buildings that were identified to reduce the additional costs currently required to build a better energy performing multi‐family house than determined by the minimum energy performance level of the national building laws. This exercise will be documented in deliverable D2.2 “Comparison of costs for new multi‐family houses, NZEBs and beyond”.

HUMIDITY ,ATMOSPHERIC temperature ,RELATIVE velocity ,CUBIC equations ,SOLAR radiation - Abstract
The effect of humidity on the climatic conditions and the turbulence around an isolated building has not been yet investigated in literature. This paper analyses the simultaneous effect of architectural and environmental parameters on the vortex creation around a building, focusing on the impact of relative humidity. Sixty-four 3D computational fluid dynamics simulations have been performed, coupling 4 values of inlet velocity, air temperature, solar radiation and building height with 4 values of relative humidity. Results demonstrated that the inclusion of humidity in the simulations has an impact on the vortex creation. Differences in values and trends of the vortex dimensions (H
c , Xc , and Lc ) were obtained compared to previous studies where relative humidity was not considered. The highest percentage difference between the two studies regards the building height, where the addition of relative humidity made the Xc value decrease by up to 56%. Among the analysed environmental parameters, building height has the higher impact on the characteristics of the vortex, followed by air velocity. The results have been compared with the analytic formula of the ASHRAE Handbook. Cubic mathematical equations have been developed correlating the vortex dimensions with building height, air velocity and relative humidity. [ABSTRACT FROM AUTHOR]- Published

Light-emitting diodes (LED) are a promising light source for the cultivation of edible vegetables in greenhouses. The spectral radiation of the light sources has an impact on plants physiological parameters, as well as on morphological features. In this study the growth of spinach plants has been carried out in experimental boxes under two white LED treatments having different correlate color temperature (CCT): the cold lighting (CL) corresponded to 6500 K, while the warm lighting (WL) to 3000 K. The work was aimed to investigate the influence of the two light spectra on plant development and comparing the results. Results showed that the different lighting treatments impact differently on plant development and on growth parameters. [ABSTRACT FROM AUTHOR]

- Abstract
The periodic stabilized regime is the condition where the temperature of each point of a certain environment varies following a periodic law. This phenomenon occurs in many practical applications, such as passive or ancient buildings not equipped with Heating, Ventilating and Air Conditioning HVAC systems and located in latitudes where the temperature greatly varies with Earth's daily cycles. Despite that, the study of transient phenomena is often simplified, i.e., considering negligible the thermal response of the indoor microclimate. An exact solution to enclosures whose microclimate is free to evolve under a periodic stabilized regime does not exist nowadays, also from an analytical point of view. The aim of this study is to parametrically analyze the thermal variations inside a room when a transient periodic temperature is applied on one side. The phenomenon has been numerically studied through Computational Fluid Dynamics (CFD) and analytically validated using a function that reproduces the daily variation of the outdoor temperature. The results of this research would lay the groundwork to develop analytical correlations to solve and predict the thermal behavior of environments subject to a periodic stabilized regime.

SUSTAINABLE buildings , *THERMAL insulation , *BUILDINGS & the environment , *ENERGY consumption of buildings , *THERMAL properties of buildings - Abstract
This paper analyzes the impact of a change in the thermal insulating material on both the energy and environmental performance of a building, evaluated through two different green building assessment methods: Leadership in Energy and Environmental Design (LEED) and Istituto per l'innovazione e Trasparenza degli Appalti e la Compatibilità Ambientale (ITACA). LEED is one of the most qualified rating systems at an international level; it assesses building sustainability thanks to a point-based system where credits are divided into six different categories. One of these is fully related to building materials. The ITACA procedure derives from the international evaluation system Sustainable Building Tool (SBTool), modified according to the Italian context. In the region of Umbria, ITACA certification is composed of 20 technical sheets, which are classified into five macro-areas. The analysis was developed on a residential building located in the central Italy. It was built taking into account the principles of sustainability as far as both structural and technical solutions are concerned. In order to evaluate the influence of thermal insulating material, different configurations of the envelope were considered, replacing the original material (glass wool) with a synthetic one (expanded polystyrene, EPS) and two natural materials (wood fiber and kenaf). The study aims to highlight how the materials characteristics can affect building energy and environmental performance and to point out the different approaches of the analyzed protocols.

Green building concept plays a fundamental role in reducing the use of resources and the impacts on human health and environment, during the whole building life cycle. Therefore, a method to measure the building sustainability rate is crucial for comparing various alternatives in terms of use of different materials, energy resources, production processes to reduce energy consumption and environmental impacts. Many protocols have been proposed to perform buildings’ sustainability evaluation; however, different operators applying these certification tools might need to make hypotheses, even different from each other, to complete the whole procedure. Hence, this work aims to evaluate whether and how the hypotheses formulated by each operator can influence the final certification level. To this end, a Round Robin Test among international partners was performed using different versions of LEED sustainability protocol to the same building with the same boundary conditions, comparing and analyzing the results provided by the participants. The final aim was to identify which issues have more influence on the final performance rate, giving to the users a deeper knowledge of the aspects included in these procedures. The results showed the potential of these building environmental certification systems, capable of offering a transversal level of environmental sustainability.

• The annual net energy saving of switching cool roofs is assessed via dynamic models. • Thermochromic cool roofs provide savings up to 19% compared to conventional roofs. • Thermochromic cool roofs provide savings up to 8% compared to cool roofs. • Limited switching magnitude comes with limited energy savings or even penalties. Cool materials are a well established solution to mitigate urban overheating. Notwithstanding, their net energy and cost impact might turn negative in year-round assessments, owing to space heating penalties. Thermochromic materials, that are able to switch from a prevalent absorbing to a prevalent reflective behaviour, may overcome this problem. Several studies at the material level show advantages and limits of the technology, however no marketable solution exists yet. This study aims at quantifying the energy saving potential of switching cool roofs to optimize the thermal response of residential buildings in the Mediterranean Basin. The task is performed by simulation in transient regime, drawing on different material modelling approaches. The analysis is carried out in three cities: Barcelona, Palermo and Cairo, representative of different areas of the Basin. Several scenarios are considered, different in terms of building insulation, transition temperature and switching magnitude. Thermochromic materials exhibit potential annual energy savings up to 8.5% and 19% with respect to cool and conventional roofs, respectively, when the solar reflectance switches from 0.15 to 0.75. Smaller annual energy savings are achieved as the switching magnitude is decreased. Due to several factors, thermochromic cool roof can also lead to annual energy penalties compared to static roofs. Further modelling and experimental efforts are needed to better predict the response of the material during the transition phase and refine the optimization process. [ABSTRACT FROM AUTHOR]
