nearly zero energy consumption

The successive and persistent heat waves that blighted spain last summer broke new records in electricity demand. specifically on 21 july 2016, peak electrical power demand reached the highest figure of the last five years during the summer season, with 40,192 mw. the widespread use of air conditioning was the main “culprit” however the demand for industrial cooling should not be underestimated.

Even before the major heat waves hit, the electricity consumption of large and medium companies last june had increased by 1.5% compared to the same month last year, according to data from the ire, the power grid index. in the past twelve months, the electricity consumption of these companies was up 2.2% on the same period last year. by sector, industrial consumption rose by 3.6% and services by 1.6%.

 

Compared to june 2014, of the five activities with the greatest electricity consumption, metallurgy demand grew by 2.5%; the chemical industry was down 1.9%; the manufacturing of other non-metallic mineral products increased by 6.6%; the food industry rose by 0.8%; and paper dropped by 17.2%. similarly, the activities that most contributed to the growth in consumption of large companies were metallurgy with an increase of 2.5%; other non-metallic mineral product manufacturing (6.6%); water collection, treatment and distribution (13%); motor, trailer and semi-trailer vehicle manufacturing (7.5%); and rubber and plastics manufacturing (3.8%). Read more…

As part of the “Madrid 0.0 Project” design competition that aimed to study a residential real estate development incorporating nearly zero energy consumption standards that took place in the Madrid municipal district of Torrejón de Ardoz, the COAM, the Madrid Architects’ Association and Solvia, the real estate company of Banco Sabadell, awarded first prize to architects César Ruiz-Larrea Cangas and Antonio Gómez Gutiérrez, from the studio Ruiz-Larrea & Asociados, S.L. The project described in this article looks at the use of systems and materials that resulted in the construction of collective housing with no active heating and cooling installations.

The world is changing. Our mentality is changing. These are not figures of speech, but a reality. Our cities need to respond to all these emerging changes as do our buildings. Rising energy costs, resource depletion and climate change have orchestrated a complete change in outlook and approaches that were previously rejected are now more relevant than ever to respond to current needs.

0.0 Solvia’s Zero Dwellings combine these new tools and apply them to the development of 98 homes in Torrejón de Ardoz, promoted by Solvia. Systems such as heat recovery, ground-air exchange, comprehensive design control to eliminate thermal bridges, together with a precise dimensioning of the insulation and joinery make 0.0 Solvia’s Zero Dwellings the first collective housing in Spain made of wood which minimises the active heating and cooling installations to the maximum.
