Article
This paper presents a study of the thermo-hygrometric behaviour of a Double Skin Façade (DSF) unit. The study aims (i) at comparing currently used calculation procedures according to European and American standards (UNI EN ISO 10077, UNI EN ISO 12631:2018, ISO 15099:2003, ANSI/NFRC 100 for the thermal performance and ISO 13788:2012 (2012) for the c...
Article
Extensive literature exists on the use of dynamic shading devices for the control of visual and thermal comfort in non-residential buildings, however research in the residential sector is far less widespread. Several control strategies and thresholds are utilised in literature, yet it is unclear how these should be chosen. The aim of this work is t...
Chapter
Advanced fenestration systems (AFS) can respond to baseline functionalities and requirements in the remit of the transparent part of the building envelope (eg, reducing heat transfer, solar control and providing view out) and can combine these to a higher level of functionality aimed at providing an occupant with excellent indoor conditions while i...

The present study aims to benchmark the models utilized for estimating the solar irradiance on vertical planes that can facilitate the determination of critical conditions, which are utilized in the glazed facade design. Accordingly, in the first part of the study, the performance of PVGIS databases for Europe for estimating the solar irradiance co...

This study focuses on the control of movable Venetian blinds. Multiple improvements to an existing on/off open-loop control strategy in a case-study apartment have been simulated in TRNSYS 18, thanks to the detailed optical and thermal modelling allowed by the Bidirectional Scattering Distribution Function (BSDF) used as input to the Type56_CFS. Th...

As the European building stock is in evident need of deep energy retrofitting to meet current European decarbonisation targets, the construction market calls for industrialised systems to boost massive renovations and activate economies of scale. The article outlines the development of an offsite fabricated system for building energy refurbishment...
Conference Paper
Complex Fenestration Systems CFS with different types of shading devices are widely used to enhance the building envelope’s energy efficiency and the occupants’ visual and thermal comfort. These technologies are characterized, among the others, by advanced shading systems, with for example complex geometries and highly reflective surfaces, that int...
Technical Report
Full-text available
The present document includes a state-of-the-art review of solar envelope systems that are already on the market or that can potentially reach that stage in a short-medium timeframe (Technology Readiness Level ≥ 4). The analysis focuses on the technological integration of such solutions in the envelope and building, but non-technical issues such as...

This paper presents a comparative study among well-established simulation tools showing their capabilities evaluating complex fenestration systems in terms of thermal and daylight performance. Two powerful and flexible toolchain approaches based on EnergyPlus and TRNSYS including third-party software are analysed in detail and their application is...
Conference Paper
Full-text available
The building sector has revealed a need for process optimization, mirrored by the ongoing discussion around industry 4.0 and increasing automation in building design and construction. Within this context, the prefabrication and standardization of building elements provide interesting opportunities for optimizing the construction process. Off-site f...
Article
Ventilated façades are applied in both new and existing buildings. It has been claimed that these components help to reduce energy use in buildings and improve occupant comfort. However, their performance strongly depends on the airflow passing through the cavity. In order to characterise and to model the behaviour of the ventilation and its effect...

Complex Fenestration Systems (CFS) can have optical and thermal behaviours dependent from the solar rays’ properties and from the air cavity type. The current most detailed calculation methods rely upon the ISO 15099 standard, which let some gaps on how to deal with such CFS. In particular, the optical and convective models might not be adequate fo...
Conference Paper

The management of solar radiation access inside buildings with large glazed façade requires considerable attention when energy saving and interior comfort has to be provided. This paper aims to present a control strategy for venetian blind applied on a shopping mall building located in Spain. The shading control strategy is based on a hierarchical...
Article
Full-text available
Vapour barriers and retarders are often needed to improve the hygro-thermal performance of the building envelope. Their use is particularly important in prefabricated timber façades, especially when critical boundary conditions occur. In the literature, very little is known about the actual performance of complete envelope packages that integrate t...

In 2016, 70 GWp of photovoltaic power has been installed globally. One of the photovoltaic sectors which could benefit from a steady growth in the near future is Building Integrated PhotoVoltaics (BIPV) that can represent also an effective solution to the requirements of the emerging building regulatory frameworks (i.e. nZEB). In this paper an esti...

Traditional façade characterisation metrics such as U-value and g-value are of limited value in the design process of buildings with adaptive façades. This issue is particularly important for adaptive façade components that have the capability of controlling thermal energy storage in the construction thermal mass. Building performance simulations c...

A modular multifunctional façade for the retrofit of shopping malls, capable of adapting to different climates and to the existing building features both by the presence of movable components and by proper sizing of the fixed ones, is under development within the European FP7 project CommONEnergy. In particular, this curtain-wall façade is equipped...

The main focus of this work was the simulation and optimization of a BIPV-façade-system configuration through the development of simulations using the software "TRNSYS". First, several limitations and constraints within the TRNSYS framework needed to be solved to develop a reliable simulation environment. Various parameters were detected which are...

Simulating heat conduction in massive walls with commercial software is reported to cause numerical instability or reduced accuracy. As contribution to the discussion, we have simulated one-dimensional heat conduction in massive walls and their dynamic thermal responses to a step, a sinusoid and time se-ries in TRNSYS, EnergyPlus, Delphin and Matla...

The paper proposes an innovative energy performances evaluation and design approach, developed during the II° Ph.D. IE A Task 40 Summer School. The aim of the work is to check the importance of a 'design with climate' approach in understanding how much climate conditions can influence the design choices. The idea is to focus on the technical and ar...
