“… Adsorption chiller: the type 290 has been developed directly by the manufacturer (SorTech AG, 2009); the model is based on a performance map rated by the manufacturer. Since the DLL cannot be modified, a post-correction has been applied to validate the model according to the dynamic performance of the chiller rated in the laboratory (Menegon et al, 2014);  Dry cooler: type 880 (Besana, 2009). The model is based on the ε/NTU method and capacitance effects are considered.…”

Dynamic whole system testing methods are applied to evaluate the performance of heating system driven by renewable energy. The application of dynamic methods is needed to perform a reliable performance evaluation since these systems work under dynamic conditions. However, some procedures described in literature are defined for a specific application.The PLPE procedure has been developed with the aims of simplification of its application and of having a general applicability. Nevertheless, the PLPE was validated only for a solar assisted heat pump system. The present paper wants to investigate the applicability of the PLPE procedure for the test of a solar cooling system. The paper shows the representability of the emulations and the accuracy of estimating the seasonal performance for different climates in the case of solar cooling systems. The PLPE can estimate the thermal SPF with an accuracy of the 10%.

“…The on-off controlled single-stage WSHP operates in monovalent mode and has been oversized to fully cover both SH and SC demand. Its capacity results in about 25 kWth and its performance has been evaluated using a performance map derived from laboratory tests (Menegon and Fedrizzi, 2016). The buffer TES has been sized considering the reference value of 15 litres/kW th with respect to the WSHP thermal power capacity.…”

An increasing population with the need of new buildings in combination with global warming is important issues ahead. Hence, for defining a clear path towards a low and zero-emission building stock in the EU by 2050, as recently stated by the new EPBD recast, Nearly Zero Energy Buildings are one of many necessary measures for climate change mitigation. Finding cost optimal solutions are important, where a short time perspective and narrow concept for evaluation may be wrong. This study presents a Net Zero Energy Building in Sweden, with verified plus energy performance in the operation phase. Furthermore, it presents an economic analysis, based on life cycle costing (LCC), where additional cobenefits are included. The study shows that the discounted, cumulative annual cost reductions due to energy savings may exceed the initial extra costs after more than 20 years. However, when including additional green values and increased property value, breakeven may occur already after roughly five years.

“…The existing methods for SCS performance evaluation and testing can be classified into two categories, depending on their approach to evaluating primary energy savings: the component approach and the global approach. Methods that are based on the component approach, such as the Component Testing System Simulation (CTSS) [14][15][16][17], the BIN [18,19] methods, consist in separately testing the main Solar Combisystem components (heat store, controllers, thermal collector, heat pump, etc.) according to existing standard tests.…”
