The main purpose of the HeLLo project is to contribute data available on literature real hygrothermal behavior historic walls and suitability insulation technologies. Furthermore, it also aims at minimizing energy simulation errors design phase improving their conservation features. In this framework, one preliminary activities study creation a in situ hot box measure analyze different technologies applied wall, quantify performance masonry building. Inside box, ‘traditional’ experiments can...

The hygrothermal behaviour of an internally insulated historic wall is still hard to predict, mainly because the physical characteristics materials composing are unknown. In this study, assessment thermal masonry palace located in Ferrara, Italy, shown. situ non-destructive monitoring method combined with a simulation tool, aiming better analyse and discuss future refurbishment scenarios. context, original U-value (not refurbished) decreased from 1.44 W/m2K 0.26 (10 cm stone wool). Under...

This paper presents the newly developed study, methodology and assessment of hygrothermal performance a historic building wall retrofitted with three different internal insulation technologies, without vapour barrier. It aims at assessing any possible condensation problems most critical point tested stratigraphy (namely, in between material) to limit modification original behaviour wall's materials addition layer, as would commonly be used. evaluation was performed through situ measurements...

The KNOW HOWse project, coordinated by the University of Sharjah in cooperation with Research Centre Architettura>Energia Ferrara – Italy, participated to Solar Decathlon Middle East 2018 Dubai, an international competition where academic teams design, build, and operate energy-efficient solar-powered houses. particular UAE climatic scenario implies consistent use cooling throughout year. For this reason, project was developed maximize passive strategies, order limit electricity demand. This...

The examination of the Italian and European legislative regulatory framework, analysis some relevant survey campaigns national school building stock show an alarming situation, as well missed opportunities. Despite fact that operations promoted by Government haven’t been effective so far, Union encourages deep retrofit interventions towards standard 'Nearly Zero Energy Buildings'. This approach necessarily implies a systemic knowledge buildings, which can be achieved with different levels...

Three correlated researches try to give operative answers the problem of defining procedures and tools for a correct survey retrofit actions existing building stock. Starting from first research on social housing energy retrofit, fast audit protocol different intervention scenarios have been defined, with ultimate purpose supporting transformation older urban aggregates; this cluster includes single buildings high historical values, which necessarily need deeper diagnosis future perspective...

This paper evaluates the influence of timber construction on architectural design through a critical analysis and comparison between two environmental building contexts that are culturally geographically different from one another:  the experience former British colonies, represented by New Zealand, Mediterranean one, described Italy. moves investigation three themes: cultural value process; performance realm (environmental, energy seismic ones as firsts); dimension. The contribution...

In the context of functional and performance rehabilitation existing heritage, internal envelope thermal insulation is often an inevitable option towards improvement historic buildings' energy efficiency.Nonetheless, besides leading to loss useful floor area, this may also lead changes on original hygrothermal behavior such walls.Applied a real case study, paper presents dynamic simulations assessment few retrofitting materials, unveiling significance proper choice materials in software's'...

ed è riconducibile a una più ampia questione che riguarda il rapporto fra l'uso delle tecniche e i significati dell'atto costruttivo.In questa direzione, secondo lei possibile riorientare e, forse, rifondare la cultura tecnologica del progetto architettonico, ripartendo da alcune connessioni perdute tra individui, comunità processi costruttivi?Esistono già evidenze rispetto alle quali necessario prospettare anche relazioni abilitanti completamente nuove l'abitare costruire?Nicola...

Geographical distances, logistic problems, and the absence of raw matter, industrial fabric, know-how prevent many countries from adopting innovative, sustainable, “green” systems for high building quality. In order to disseminate these principles through “colonization” new markets, it is necessary think how export those that, although not locally fabricated, are considered green thanks other sustainable features. The paper proposes a design method production/construction process...

The persisting economic crisis and the necessity for more sustainable construction processes imply need innovative strategies to reuse existing building stock. Retrofit recycling plans are already active whole city districts, adopting urban densification strategy reduce consumption of resources, promoting functional, technological, energy refurbishment districts study introduces considerations tools increase efficiency retrofit action onto abandoned degraded area through improvement their...

Among the multiple possible interventions on historical and consolidated urban contexts, two different approaches are most diffused today: interpreting project as a discontinuity with surrounding environment, one side, reading it form of continuity existing fabric, other. Starting from these methods through analysis international state-of-the-art in field adaptive reuse, article explores opportunities third direction, resulting synthesis above showing levels controlled densification.
