The Life Cycle Assessment methodology has proven to be effective in evaluating the impacts of goods production throughout their life cycle. While many studies are available on specific products, in recent years a growing interest is related to the analysis of services, including energy supply for final customers. Different LCA evaluations are available for electricity, while the heating and cooling sector has not yet been properly investigated. The objective of this study is the analysis of the specific impacts of the heat supplied to the final users connected to a district heating system, in comparison with traditional individual natural gas boilers, which represent the baseline heating solution in several urban contexts in Europe. The results show that the comparison is heavily dependent on the allocation method used for combined heat and power plant production. District Heating impact on heat supplied to the users can vary from 0.10 to 0.47 kgCO2eq/kWh, while distributed natural gas boilers present an overall impact equal to 0.27 kgCO2eq/kWh.

The energy transition driven by the need of a deep decarbonization to limit the world temperature rise requires coordinated actions across the whole energy sector. Among other measures, the strong development of renewable energy sources in the power sector is gaining momentum in different parts of the world. The possibility of producing low-carbon electricity leads to a renovated interest in increasing electricity penetration in final sectors, especially in transport and buildings heating. However, a large share of renewable electricity comes from non-dispatchable sources, notably wind and solar PV, and their daily and seasonal variability needs to be matched with the demand profiles of those sectors. In particular, the charge of electric vehicles shows a relatively constant demand on a seasonal basis while attention must be paid on the daily operational logic to fully exploit available power from solar and/or wind. On the other hand, the operation of heat pumps for building heating shows a strong seasonality that may be an issue in countries that have a larger renewable production during summer. This research work is focusing on this specific issue, with the aim of improving the common practice of evaluating energy consumption and emissions on an annual basis, thanks to a detailed analysis based on hourly time-step, both for the electricity generation mix and for the heat pumps demand. To increase the significance of the results, different countries across Europe have been analyzed and compared.

Direct absorption solar collector (DASC) have recently attracted increasing interest in combination with some new absorbing fluids, obtained through the suspension of nanoparticles in water or other liquids (nanofluids). A volumetric direct absorption in a solar collector is in principle more convenient than a superficial indirect one, assuring a temperature distribution whose peak is internal to the fluid instead and not on the external surface, as in superficial one, thus promising lower heat losses. Nanofluids, i.e. fluids with a suspension of nanoparticles, such as the carbon nanohorns we choose as case study, can be considered a good and innovative family of absorbing fluids, due to their higher absorption coefficient than the pure base fluid and to their high stability under moderate temperature gradients. In this paper, we focus on the application of direct volumetric absorption by nanofluids for civil applications, which have a typical operative temperature lower than 100 °C. A DASC using nanofluids with different nanoparticle concentrations is compared to a commercially available indirect vacuum tube solar collector. The comparison is made between simulated performance of the DASC and the nominal performance of the commercial collector. The simulations are made with a CFD model, that leverages original experimental measurements of the optical properties of the considered nanofluid. It is shown that the DASC concept is more convenient in case of higher heat losses, i.e. in case of a high transmittance solar collector or of very high temperature of the heated fluid. It is also underlined the importance of balancing the heat absorption and heat transport function of the fluid. The simulations of the first considered design reveals, in fact, that the thermal field does not completely develop in the pipe, due to the large pipe diameter in relation to the flow and to the low heat losses, thus producing a low bulk temperature. The addition of a compound parabolic concentrator (CPC) and the adoption of an annular pipe (triple tube) improve the performance in terms of average bulk temperature, though not matching yet the surface reference collector in terms of efficiency.

We can use the concept of exergy to analyze a human body as a heat emitter: while generating heat continuously, the body remains at roughly the same temperature through physiological responses such as shivering, sweating, breathing thus raising/decreasing the core and/or skin temperature to maintain effective heat dissipation. Existing literature provides an estimated exergy consumption rate of the human body ranging from 2 to 5W/m2, while nearly unanimously agreeing on a local exergy consumption minima points to potential individual thermal comfort. To clarify the underlying assumptions used in the existing human body exergy models, we analytically and numerically reviewed the terms used for assessing metabolism, radiation, evaporation, and convection exergy changes of the human body in this paper. We observed overestimations of exergy from metabolism, underestimations of exergy change through radiation, and some caveats in the signage of convective exergy losses in the results we obtained. We were also able to propose an improved expression to estimate human body radiation exergy exchanges as well as selecting reference temperatures that are more process-specific. Future studies that provide experimental verification of these models was also deemed necessary.

The design optimization of water basins for the refrigeration of intermittent high-power heat sources, by mean of CFD simulations, is presented. A case study of an experimental facility is considered, that foreseen two large water basins as thermal storage, with volume of 315 m3 and 500 m3 respectively, and an installed nominal cooling power around 25 MW for the cooling of an intermittent load, with peak power of around 65 MW. A strong horizontal stratification has been looked after in the preliminary design, which include a labyrinth of walls and weirs, and water inlet/outlet plugs positioned at the opposite side of the basins. The intensity and the role of this stratification have been explored using a CFD software, simulating both winter and summer sceneries. Some variants to the original design have been studied, in order to optimize the stratification of water temperatures. It is shown that a large water storage with an optimal design could help very much in reducing cooling power demand in case of intermittent thermal load.

The liquid desiccant membrane cooled ceiling (LDMC-C) and displacement ventilation (DV) system removes humidity directly from the space. However, LDMC-C/DV system does not control humidity in the lower occupied zone. In this work, a method for humidity control is proposed where fraction of the dehumidified cool dry air adjacent to the LDMC ceiling is extracted from the exhaust stream and mixed with the DV supply air stream. This leads to re-establishing of the thermal comfort; reducing the DV cooling requirements, and saving energy. A time-dependent mathematical model of the LDMC-C was developed and validated experimentally. The LDMC-C transient model was then integrated to the mixed DV space model and was applied to a case study. When mixing strategy was applied, the relative humidity dropped by an average of 8.72% in the occupied zone within 12 minutes and energy saving of 24% was achieved compared to in-duct conventional dehumidification.

The space heating of buildings represents one of the most important causes of energy consumption in Europe. The necessity to increase the share of renewable energy within the sector is hindered by the difficulty to renew and refurbish the existing building stock. In this context, heat pumps can have an important role in helping increase the renewable share of thermal energy production for the civil sector, in particular in those countries in which the electricity generation mix has large contributions from renewable energy sources. The paper presents a real-data analysis and a numerical simulation to evaluate the opportunity to substitute traditional heat generation systems (natural gas boilers) with air-source heat pumps or hybrid solutions. Three buildings located in Turin (Italy) are taken as case-study, and the hourly profiles of outdoor temperature, water supply temperature and absorbed thermal power are used to simulate four heat generation scenarios, that are compared in terms of primary energy consumption. Results show that (1) the substitution of the traditional natural gas boiler with a heat pump (with backup electric resistance) is always favorable (18% to 32% of primary energy reduction); (2) the influence of water supply temperature of each building on the overall primary energy saving is very high; (3) the adoption of a hybrid system (heat pump and natural gas boiler working alternatively) provides advantages in terms of reduced primary energy consumption only if the required supply water temperature is high. Further studies will investigate the economic aspects and will introduce comparisons with condensation natural gas boilers

Ground source heat pump (GSHP) is an innovative and perspective technology able to use the ground as a thermal sink or heat source. If combined with system operating at relatively low temperature, it represents a high efficiency solution for the heating of buildings. Complementarily, during cooling operation it has a good advantage with respect to air-cooled systems, because the ground temperature is stably lower than the outdoor air one. Geothermal heat pump systems are able to reduce the environmental impact of buildings for space heating and cooling by using the ground as an energy renewable source. This paper presents a review on the GSHP systems presenting both a summary of different ground-source typologies of heat pumps and a thermodynamic approach for their modeling. The irreversible thermodynamic approach is here summarized and exposed for a complete GSHPs system. This analytical approach is particularly useful for implementing an optimization design tool for GSHP systems. Recently many works have been published about exergy analysis of these systems. Those works suggest that future lines of development may be considered: a) the optimization based on the transient performance of GSHP systems and not on the sole design condition; b) the integration of irreversible thermodynamic optimization approach into the algorithms of control systems. The diffusion of optimized GSHP systems is essential in order to reduce fossil fuel consumption and CO2 emissions, complying with the EU's directive

This paper presents the general concept of the NAC (Natural Air Conditioning)-wall system and some experimental results on a first prototype. The originality of the system is to perform a solar DEC (Desiccant, Evaporative Cooling) open cycle by exploiting natural buoyancy driven ventilation, thus avoiding the use of fans. The supply air is dehumidified by a zeolite based adsorption bed and is cooled indirectly by an evaporative cooler, through a low pressure heat exchanger. Eight days measurements were performed, each including a sample with five adsorption/regeneration cycles. During the first measurements, thermal COPs were in the range 0.30 1.01, depending on duration of regeneration and absorption phases. This led to a better tuning of the system, which gave for the remaining samples an average COPth of 0.64, with an average electrical COP of 12.7, calculated considering electrical consumption of water loops pump

This work reports the experimental testing of a prototype of a new adsorption stage for solar DEC (Desiccant Evaporative Cooling) systems, in which airflow is activated by natural forces. The adsorption stage takes place in an air/water coil, coated with a thin layer of zeolite SAPO34 material. The thin coating configuration allowed testing of a concept of natural buoyant airflow on the coil, both during adsorption and during desorption phases. The heat released by the sorption phenomenon drives the airflow on the coil, whereas during the desorption, hot water flows through the coil and activates the convection. The tests proved the feasibility of the concept, though revealing the need to optimize the system configuration

Reducing primary energy consumption is an essential issue for the sector of building construction. This paper refers to building ventilation systems and focuses on low pressure flat plate heat exchangers, designed for low pressure drops and low air velocity, minimizing the electrical consumption of fans. The device is conceived for working within passive ventilation systems, as a ventilation heat recovery stage during winter and sensible heat dissipation during summer. CFD simulations are used for testing and optimizing some flow-mixing device (or turbulators) inside the heat exchanger, in order to minimize the need for fans, still assuring an acceptable efficiency. Experimental testing of the prototype is in good agreements with numerical simulations.

The study proposes and compares low-cost strategies to improve the quality of existing building stocks,with special regard to a widespread Indian residential typology. A dynamic energy model of this particularlocal building typology was simulated with Energy Plus software and validated by comparing it with someoriginal in situ measures, recorded by hourly step. The validated model was used to simulate a selectionof low-cost and technically simple interventions, whose effects on the energy performance and indoorcomfort were compared to the baseline case study. Comfort performances have been evaluated usingcomfort indoor degree hours (CIDH) and the TSI index. A combination of the most effective solutions wasproposed and simulated. The results were used to assess possible improvements of comfort (reductionof CIDH) and savings of energy consumption (referred to an A/C scenario). Finally, the role of occupants'behaviour was further investigated

Low power adsorption chillers with low desorption temperatures deserve particular attention, because of the possibility of driving them with a solar thermal system integrated with buildings. The monitoring of a recent solar cooling installation in Turin, Italy, has pointed out the opportunity of developing a dynamic mathematical model, in order to simulate the transient performances of this plant. Focusing on the aforementioned low power-low temperature adsorption chiller category, this work proposes a numerical model of the systems, that include a novel zeolite as the adsorbent and water as the refrigerant fluid. The simulation results have been verified by means of the nominal values of one of the very few commercial chillers of this typology available on the market, and have compared with experimental data found in the literature for similar plants.
