Chapter
Chapter 11. Experiences from installed custom made systems Within the following chapter custom-made solar thermal heating and cooling systems are discussed. The target of the chapter is to present practical experiences of worldwide installed systems and thereby enhance the theoretical knowledge. The chapter starts with an overview of documented int...
Article
The term Net ZEB, Net Zero Energy Building, indicates a building connected to the energy grids. It is recognized that the sole satisfaction of an annual balance is not sufficient to fully characterize Net ZEBs and the interaction between buildings and energy grids need to be addressed. It is also recognized that different definitions are possible,...
Article
The concept of Zero Energy Building (ZEB) has gained wide international attention during last few years and is now seen as the future target for the design of buildings. However, before being fully implemented in the national building codes and international standards, the ZEB concept requires clear and consistent definition and a commonly agreed e...

Full-text available
Net Zero Energy Building" has become a prominent wording to describe the synergy of energy efficient building and renewable energy utilization to reach a balanced energy budget over a yearly cycle. Taking into account the energy exchange with a grid infrastructure overcomes the limitations of seasonal energy storage on-site. Even though the wording...
Article
Full-text available
The idea of a Net Zero Energy Building (Net ZEB) is understood conceptually, as it is understood that the way a Net ZEB is defined affects significantly the way it is designed in order to achieve the goal. However, little agreement exists on a common definition; the term is used commercially without a clear understanding and countries are enacting...

The new primary school built for the Novale village, in the community of Lajon (South Tyrol / Italy), achieves ambitious energy and environmental efficiency goals. For this, the project complies with the criteria of a “KlimaHaus Gold +”. It became operative in July 2006 and it is the first Passivhaus School in Italy. It won the “Best CasaClima” awa...

In the present work 4 different energy supply systems are compared. Two solar thermal assisted systems, one conventional system and a photovoltaic assisted system have been considered. The energy load curves and the available roof area of a large scale office building located in northern Italy have been taken as a starting point. The energy system...

This paper presents the innovative energy system of a listed building in South Tyrol / Italy, which was refurbished to a solar active building. Design values draw a most promising picture, forecasting a reduction of CO2 emissions by 30% and of electricity from the grid by more than 55% compared to a reference scenario without solar collectors, abso...

This paper presents the results of the monitoring activities carried out at EURAC Research, a building office which is energy supplied by a CHCP system including a large solar thermal installation, an absorption chiller and an AHU. Monitored values have resulted well different from the design values. The control strategy has emerged to play a cruci...

The present work reports the main issues of coupling solar collectors and cogeneration units for heating and cooling purposes which have been derived from the detailed analysis of a study case. The work suggests a procedure for planning such systems so that solar collectors and a cogenerator do not interfere in their respective operation. The proce...
Article
This paper presents Low Energy Database a software tool which has been developed with the aim to promote sustainable buildings. The Low Energy Buildings Database provides criteria for designing civil and manufacturing buildings. It mainly exposes architectural features, energy supply systems and automatic control devices suitable for the optimizati...

SUMMARY On the subject of high energy efficiency systems, the present work focuses on Combined Heating, Cooling and Power (CHCP) plants, made up of gas engine as prime mover and absorption chiller as cooling device, combined with Evacuated Tube solar thermal Collectors (ETC). Besides the advantages, i.e. electricity on site, heat recovery, thermal...

... Many re-searchers have demonstrated the feasibility of solar powered adsorption cooling systems and studied the influence of various parameters like solar insolation, ambient temperatures, etc. and arrangements like auxiliary heating, mass recovery, etc. on their performances ( [4], [5], [12). In order to realize a complete autonomous system, the primary challenge has been the sizing of solar collector and storage system for appropriate demand matching, which requires the use of dynamic simulations [11]. ...
... Therefore, the concept of a new energy building is created, which is realized through the following ways: first, the way of building electricity consumption is changed to "supply-oriented, demand responsive", that is, the electrical device flexibly adjusts the use time according to the actual photovoltaic (PV) power generation status and consumes the power in time when the power capacity is sufficient or suspends/reduces the power consumption; second, the internal storage system is developed to cover the shortage of electricity dynamically; third, the storage and consumption capacity of the electric vehicle is dynamically used to flexibly meet the building power demand (Igor et al., 2012;Kapsalaki et al., 2012). ...
... In this phase, every unit has solar panels installed on the roof in the residential gated community, and On-grid is the connection form that has been selected. It could buy electricity from the grid as well as pump excess energy back into the grid, thus, on-site power, high storage space, backup generators, energy losses due to energy storage or conversion, and an oversized renewable energy generating system are avoided in off-grid zero energy buildings [28]. ...
... Because better performance could be achieved by means of double effect absorption chillers for GT and MT and single effect absorption chillers for RE, the coefficient of performance (COP) for absorption chiller is assumed 1.2 for GT and MT and 0.7 for RE (Firestone, 2004). In addition, the COP of compression chiller is assumed 3.5 (Chen et al, 2009). The amount of cooling produced by each chiller is the product of COP and the input energy. ...
... The experimental data were measured by the installed monitoring system. For the system, designed in 2000 by Carlini and Mumelter, already several analysis and optimizations have been carried out [2] [3]. For the calculations and simulations the load 2/8 profile of the year 2007 was used (see Figure 1). ...
... The production of electricity by photovoltaic and wind energy systems can instantly cover up to 50% of the building load in some regions such as Tangier and Marrakech. The load matching between building load and energy generation can be improved by adjusting the demand to the generation and/or by regulating the generation to the needs [49]. ...
... Net-Zero Energy buildings (NZEBs) have been recognised by leading jurisdictions internationally as one of the key whole building solutions for addressing increased greenhouse gas emissions due to buildings' operational energy use (Lucon et al., 2014;US DOE, 2015;GBCA, 2016). Many researchers have investigated different aspects of NZEB such as definitions (Attia et al., 2011;Sartori et al.,2010Sartori et al., ,2011Sartori et al., ,2012Srinivasan et al., 2012;Torcellini et al., 2006), classification , calculation methodologies (Marszal et al., 2011), design approaches (Aelenei et al., 2013(Aelenei et al., ,2017Ascione et al., 2016;Athienitis et al.,2010;Athienitis and Brien, 2015), as well as the potential to reduce costs (Torcellini et al., 2015). Mavrigiannaki et al. (2021) presented a comprehensive approach involving dedicated processes, tools, protocols, and technologies for the application of NZE at a settlement scale. ...
