Monitoring results and optimization of a façade integrated ventilation concept for building retrofit

An office building of the Fraunhofer Institute for Solar Energy systems (Fraunhofer ISE) in Freiburg was retrofitted in 2012 with an innovative concept based on technology integration in the façade. Prefabricated window modules integrating air inlets and outlets, façade integrated air ducts and a heat and moisture recovery ventilation device were implemented. A long term monitoring was set up including energy, temperature, CO2 and humidity measurements.

Proposed change in Spanish regulations relating to indoor air quality with the aim of reducing energy consumption of ventilation systems

The ventilation required in order to maintain acceptable indoor hygiene standards results in a significant consumption of energy. Currently the Spanish regulations on indoor air quality (IAQ) require minimum rates for delivery-to and extraction-from the habitable rooms of residential buildings. These rates are not adjustable, so ventilation systems based on variable ventilation rates, are not normally deemed acceptable unless a comprehensive statement of compliance is provided, justifying the proposed ventilation solution.

Analysing the Resilience of Brasília’s Superblocks in a Changing Climate

In Six Degrees: Our Future on a Hotter Planet, Mark Lynas describes possible world scenarios as global temperatures rise. The central region of Brazil, where Brasília is located, will suffer major changes in its microclimate.Brasília's built environment has already provided a comfortable indoor and outdoor condition through planned urban design and vegetation.
