Research and practice: The bio-responsive facade
In Germany more than 8 % of the total energy consumption is provided by bio-energy. Apart from wind energy, it is the second largest renewable source for electrical power generation. An outstanding feature of biomass is that it is available as a solid (e.g. timber pellets), as a liquid (e.g. bio-fuel), and as a gas (e.g. methane) to be used in extremely diverse ways in the fields of power and heat generation. In contrast to electrical power generated through photovoltaics or wind energy, biomass presents a form of 'solar energy' that can be stored without loss or the use of special technical equipment such as batteries.
