Original language Description:
La domanda di condizionamento estivo nel settore terziario è in rapido aumento, sia perché vengono richieste condizioni di comfort più elevate, sia perché nell’ultimo decennio l’aumento delle temperature si è manifestato in modo più evidente. Al tempo stesso, le tecniche passive o semi-attive, impiegate per secoli al fine di preservare buone condizioni di comfort interno, sembrano essere state dimenticate nella più recente pratica edilizia. L’uso crescente di impianti di condizionamento con macchine frigorifere a compressione alimentate ad energia elettrica è altresì causa dell’aumento della domanda di picco di potenza elettrica in estate, che, in numerosi casi, raggiunge la capacità limite delle reti. L’emissione di gas ad effetto serra, che cresce con la produzione di energia o con la perdita di fluidi refrigeranti, aggrava ulteriormente il circuito vizioso legato al cambiamento climatico. Esiste ormai un‘ampia scelta di tecnologie per il raffrescamento passivo, sia per edifici in fase di progettazione, sia per quelli esistenti, utili per migliorare le condizioni di comfort interno senza dover ricorrere all’impiego di impianti di condizionamento dell’aria e per ridurre drasticamente il fabbisogno energetico estivo. Inoltre esiste in natura ampia disponibilità di radiazione solare. E le tecnologie solari per il raffrescamento presentate in questa sede hanno dimostrato, in alcuni casi anche nel medio - lungo termine, di essere efficienti e affidabili. Queste tecnologie fanno uso di fluidi refrigeranti non nocivi (generalmente acqua) e comportano consumi energetici minimi rispetto agli impianti tradizionali.

Original language Description:
Na última década a procura de ar condicionado no sector terciário aumentou, resultado da procura de um melhor conforto e das elevadas temperaturas no Verão. As técnicas passivas e semi-activas utilizadas durante séculos para manter as condições de conforto interior, parecem ter sido esquecidas em muitos dos novos edifícios. Este desenvolvimento da climatização em edifícios é responsável por um aumento da procura de energia eléctrica durante o Verão, que por diversas vezes atinge os limites da produção e distribuição de electricidade. Associada à procura está o aumento das emissões de gases de efeito de estufa, quer devido à produção de energia, quer pelo derrame dos fluídos refrigerantes, contribuíndo para o ciclo vicioso das mudanças climáticas. Como é demonstrado na primeira parte desta brochura, uma larga gama de soluções passivas disponíveis permitem melhorar as condições interiores tanto para novos edifícios em fase de projecto, como para edifícios já existentes, reduzindo o recurso a sistemas activos de ar condicionado. A tecnologia de arrefecimento de edifícios com energia solar já provou em alguns casos, perídos superiores a 10 anos, a sua eficiência e viabilidade. Estas tecnologias utilizam como fluído refrigerante um fluído inofensivo (água) e muito menos energia primária que os sistemas clássicos. Assim, porque não utilizar a energia solar para manter no Verão as condições de conforto interior aconselhadas para os edifícios?

This report describes the characteristics of a small size cogeneration plant built at Castel D'Aiano, on the Italian central Apennines mountains, based on wood chips gasification and a Stirling engine. The report includes also information on costs for building the plant. The structure of the micro cogeneration plant is as follows: - updraft gasifier produces a gas from wood chips, 200 kWt thermal capacity - a combustion chamber where the gas is burnt in order to provide thermal energy to the electricity generator - an internal combustion Stirling enginge coupled to an electricity generator of 35 kWel power - a heat recovery system in order to send the heat to the district heating network The network serve a small school complex. The overall capacity of the system is: 35 kW electrical power and 140 kW thermal power

Questo report descrive le caratteristiche di un piccolo impianto di cogenerazione realizzato a Castel D'Aiano, negli Appennini centrali in Italia, basato sulla gassificazione di cippato di legno e su un motore Stirling. Il report include anche informazioni sui costi di realizzazione dell'impianto. Il sistema cogenerativo consta di: • Un gassificatore “updraft” che produce un gas combustibile a partire dal cippato, della potenza nominale di 200 kWt • Una camera di combustione dove il gas viene bruciato per fornire energia termica al motore di generazione • Un motore a combustione esterna a ciclo Stirling accoppiato ad un generatore di energia elettrica della potenza nominale di 35 kWel • Un sistema di recupero dell’energia termica da avviare all’impiantistica per il riscaldamento degli edifici La rete serve un piccolo complesso scolastico. La potenza complessiva del sistema è di 35 kW elettrici e 140 kW termici.
This report summarizes the activity of the work group lead the French Government and ADEME.

Ce groupe a analysé entre Janvier et Juin 2008, l’ensemble des mutations économiques et technologiques que devront engager les acteurs de l’industrie et des services concernés par la diffusion massive des nouvelles technologies de l’énergie intégrées aux bâtiments neufs et existants. Les technologies concernées sont le solaire thermique et PV, la biomasse et les pompes à chaleur.
The performance of building integrated polygeneration in terms of energy savings and environmental impact reduction are evaluated for small, well insulated office buildings by means of a simulation based case study. The micro-polygeneration system assumed comprises a natural gas driven micro-cogeneration (CGU) unit, a thermally driven cooling (TDC) unit and a back-up boiler. Cases with different combinations of capacities and efficiencies of CGU and TDC unit are analyzed, and compared to the reference system with gas boiler and grid electricity. The office building considered complies with advanced building standards. Cooling and heating is provided by thermo-active building systems (concrete core pipe systems). The building loads are determined as 1h-values with the whole-building simulation program TRNSYS, using standard occupancy and electric demand profiles specified by Swiss standards. Energy carriers are natural gas as fuel and grid electricity considering three different generation mixes: Swiss, European and combined cycle power plant.
