HoHo Vienna is one of the tallest wooden buildings in the world and a lighthouse project for sustainable timber construction. Thanks to the level of thermal insulation, resource conservation, energy efficiency and sound insulation, it has been awarded with the certification LEED Gold and ÖGNB gold from the Austrian Society for Sustainable Buildings.

Built in 2019, the Eisbärhaus was designed as a passive building comprising two units. Building materials were selected according to guidelines provided by the Austrian environmental association Umweltverband Vorarlberger Gemeindehaus. All exterior walls consist of wooden timbers treated with cellulose to provide thermal insulation (layer thickness: 42cm).

Onze wereld ‘as built’ vandaag en morgen is steeds in evolutie. Het zoeken naar een evenwicht in de 4 basiselementen van het leven, “aarde-water-vuur-lucht”, heeft de mensheid steeds doen overleven. De isolatielaag als onderdeel van het beschermd volume moet de bewoner/gebruiker in een harmonieus en aangenaam evenwicht brengen met de 4 bovenstaande natuurelementen.

Aerogels are open-porous, high-performance thermal insulation materials that can be used for very thinbuilding insulation. So far, the application conditions of these materials and their potential in heritagebuildings have not yet been described comprehensively. This review shows the technical properties ofcommercially available aerogel materials – such as blankets, boards and renders – and their use scenariosin heritage buildings, taking into account the heritage criteria of authenticity, integrity, reversibility andcompatibility.

This is the first block of housing certified in Spain built in 2017 under the Passivhaus standard, and therefore has a demand for heating below 15kWh / m2a, and a heating load of 10W / m2.
This implies that a floor of 75m2 will have a heating load of only 750W, so with a hair dryer there would be enough to heat two houses.
To achieve this the following principles have been applied:

Historic buildings are defining elements of city centres but also responsible for a large share of greenhouse gas emissions. In order to reduce their energy demand, it is important to improve envelopes’ thermal transmittance without damaging the historic integrity of their façades by applying interior insulation.
Thus, a detailed planning is needed to guarantee that case-specific variables are well considered. In this study, a holistic performance-based evaluation method is developed.

The seismic and energy retrofitting of existing European buildings with innovative materials is addressed in this report. The need for retrofitting of old buildings emanates from their substandard design in terms of both earthquake resistance and thermal insulation. This is revealed during strong earthquakes that result in collapses and damages of old buildings and consequently in economic losses, severe injuries and loss of human lives.

The rapid worldwide growth of the construction industry during recent decades has resulted in an enormous increase in the global production of Construction and Demolition Waste (CDW), placing an enormous strain on the environmental. The industry urgently needs to implement changes to economic policy and decision-making criteria to address this issue and to safe-guard the environment.
Some challenges to be overcome:
