The paper concerns the definition of guidelines in the design of a new urban settlement, based on system energy utilization and building environmental impacts and sustainability improvement. The study refers to a 160000 m2 area sited on the outskirts of Carmagnola, a city close to Torino, where the municipality decided to locate about 1260000 m3 of commercial buildings: offices, shopping centres, a trade fair area, a cattle market, a multi-hall cinema, hotels, restaurants, industrial sheds.
EECCAC is an EU funded project, where twelve participants (National Energy Agencies, Manufacturers, University laboratories and Electric utilities) from eight countries gathered to identify the most suitable measures to achieve market transformation in the direction of energy efficiency of central air conditioning systems in Europe. Within the project, some energy efficiency options (EEO) have been analysed, and a summary is presented in this paper. After setting some starting points for building, climate and simulation engine, we will present the list of HVAC system EEO covered.
Air-conditioning and cooling contribute significantly to the energy consumption of a lot of existing office buildings, especially when primary energy factors are taken into account. "Lean" building concepts however can diminish the cooling energy demand by passive cooling strategies. Compared to mechanically cooled or air-conditioned buildings the resulting indoor temperatures are floating in a broader band during summer and might exceed the given boundaries of codes and regulations on thermal comfort for short periods.
To gain access to the energy use in office buildings, the German Federal Ministry for Economy 1995 launched an intensive research and demonstration programme. In advance of the 2002 EU energy performance directive a limited primary energy coefficient of about 100 kWhm-2a-1 as a goal for the complete building services technology was postulated (HVAC + lighting). Further condition was that active cooling be avoided.
A single family detached dwelling was partly renovated for structural reasons. This was an opportunity to rethink the concept of the living space with adjacent sunspace. The new structure is flexible, to take account for the varying occupation, by a sliding separation wall. A balanced ventilation system with heat recovery must guarantee good indoor air quality at a minimal energy cost. The external construction is equipped with a sloped green roof, a high glazed facade with innovative framework and triple Argon filled glazing (U 0.8 W/mK) with warm-edge spacer.
La tendencia en las nuevas normativas energéticas de todos los países pasa por transformar requerimientos prescriptivos en prestacionales, es decir, en lugar de limitar el comportamiento de cada elemento o del edificio en su conjunto, con una serie de val
La exposición a contaminantes del aire interior es muy importante en términos de potenciales efectos negativos, particularmente en los niños que pasan un tercio de su tiempo en las escuelas. Se eligieron 6 escuelas infantiles situadas en el Bajo Nervión c
Ventilación es el proceso que permite sustituir el aire ambiente interior de un local, aire viciado, suministrando aire fresco, ya sea por medios naturales o mecánicos. Sin tener en cuenta si el aire suministrado se difunde por todo el recinto o si despla
Nella ventilazione a dislocamento, l’aria fresca e a bassa velocità è immessa direttamente nella zona occupata a livello del pavimento; essa quindi si muove verso l’alto per effetto delle forze di galleggiamento alimentate dai pennacchi termici all’intern
Aumentar los niveles de ventilación por las exigencias de los usuarios, como por las nuevas normativas sobre calidad del aire, implican un aumento en el consumo de energía, pero es imprescindible reducir este consumo para minimizar el gasto tanto económic
