Muchos son los aspectos que interesan en la arquitectura de Lacaton y Vassal y que son analizados en los distintos artículos que se incluyen en esta publicación. En ocasiones,
las acciones humanas tienen la cualidad de despertar un interés que va más allá del objeto mismo para el que fueron realizadas. La mayor parte de los proyectos y obras de
Lacaton y Vassal posee esta cualidad que, entre otras cosas, se traduce en un alto valor pedagógico que, en este caso, tiene carácter metodológico
HÍBRIDOS XXL. El límite entre edificio y ciudad
El progreso imparable de la tecnología lleva directamente asociado un cambio radical en las posibilidades de la arquitectura. A lo largo de la historia encontramos innumerables ejemplos que tratan de llevar al límite el
concepto de escala. Hoy en día, la construcción de edificios híbridos XXL
puede generar un límite difuso entre edificio y ciudad. ¿Es posible introducir
la ciudad entre cuatro paredes?The unstoppable progress of technology radically changes architecture
possibilities. Throughout history we can find many examples of buildings
that try to overstretch the concept of scale. Nowadays, construction of XXL
hybrid buildings can create a diffuse borderline between the building and
the city. Is it possible to insert the city into four walls
Evaluation of the Thermal Comfort and Energy Demand in a Building with Rammed Earth Walls in Spain: Influence of the Use of In Situ Measured Thermal Conductivity and Estimated Values
This paper describes the influence of thermal parameters—conductivity, transmittance, and thermal mass—in the estimation of comfort and energy demand of a building with rammed earth walls, and consequently, the compliance with standards. It is known that nominal design data does not match in situ measured values, especially in traditionally constructed buildings. We have therefore monitored a room in a building with rammed earth walls, designed a computerised model, and compared four different alternatives where we have changed the value for the thermal conductivity (in situ vs. estimated) and the consideration of thermal mass. When we then analyse the compliance with the Spanish energy saving code, using measured values would result in lower differences with the standards’ limits and even comply with the global thermal transmittance (K-value) requirement. This would mean a more realistic approach to the restoration of traditional buildings leading to the use of thinner and more suitable insulation and retrofitting systems, encouraging the use of rammed earth in new buildings, and therefore reducing the carbon footprint due to materials used in construction. Results show that the building model that uses in situ values and considers thermal mass (S1) is closer to reality when assessing thermal comfort. Finally, using nominal data would result in requiring 43% more energy in the selected winter period and 102% more energy in the selected summer period to keep the same comfort conditions as in the alternative where measured values are used
