Esta casa solar es una casa tradicional, con paredes de piedra y techos de pizarra. Incluye elementos de la arquitectura tradicional. Las nuevas tecnologas que tienen en cuenta las condiciones ambientales de la vivienda tambin se han introducido. Las ultimas teoras sobre sostenibilidad tambin han guiado la construccin de este edificio. La casa esta construida en el Principado de Andorra, a 1260m sobre el nivel del mar. Los pirineos le dan un clima alpino, con inviernos fros (-12C) y veranos templados (29C) El sistema solar combina los sistemas activos y pasivos.

Se ha planteado utilizar las plantas enfriadoras de agua con condensadores enfriados por agua (tipo standard), como máquinas Enfriadoras y Calentadoras de utilización simultánea en sistemas de climatización a cuatro tubos; y se expone en ésta ponencia de

Japanese traditional buildings have many features, which are effective for cooling interior. For examples, “farm house” has thatched roof, large window and earthen floor, and “storehouse” has a roof with air gap and thick mortar wall. It is important to a

In principle, there is a strong consensus that energy performance regulations should be as simple as possible. In practice, several of the existing procedures are lengthy and far from easy to quickly understand. The paper tries to clarify the various challenges for achieving the required quality. Specific attention is given to summer comfort issues and passive and low energy cooling.

The net evaporation process is investigated by performing non-equilibrium molecular dynamics simulations. The transient density, temperature and pressure profiles are statistical calculated, and the net evaporation flux is obtained from molecular level. With Hertz-Knudsen- Labuntsov equation, the evaporation coefficients based on nonequilibrium molecular dynamics simulations are computed and compared with the data calculated by the equilibrium molecular dynamics simulations and the transition state theory.

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.

Built environment is a manifestation of the technological innovation. The way technologies are applied in design and construction of buildings, have direct implications on the amount of energy consumed. In modern context buildings represent enclosed, isolated boxes/systems where environment is artificially controlled. This requires considerable energy. A problematic relationship between architecture and technology is evident. A large part of Indian Subcontinent has for majority of year ample Sun- renewable, nonpolluting, abundant and direct source of all present natural cycles on earth.

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.
