The acceleration of the development of the Metropolitan Mamminasata area has an impact on the socio-economic dynamics of the community and the use of excess energy resources. The purpose of this study was to analyze (1) economic growth and energy security work as determinants of urban development for Metropolitan Mamminasata, (2) the effect of economic growth, energy consumption, availability of transportation infrastructure, and renewable energy on the quality of the environment and the sustainability of the Metropolitan Mamminasata system, and (3) renewable energy management strategies and sustainable urban development for Metropolitan Mamminasata. An explanatory sequential approach was used. Data were obtained through observation, surveys, and documentation. The results showed that renewable energy which has the potential to used, in the Mamminasata Metropolitan urban area to support economic growth and increase urban productivity, namely water energy, wind energy, and biomass energy. Furthermore, it takes the effectiveness and efficiency of energy users toward improving environmental quality. Economic growth, energy consumption savings, the availability of transportation infrastructure, and renewable energy have a significant effect on environmental quality, with a determination coefficient of 82.3%, and the sustainability of the Metropolitan Mamminasata system, with a determination coefficient of 75.7%. Use of renewable energy in the management of urban development will require support from government policies, as well as community and business participation. This study recommends a renewable energy management strategy as an important part of supporting the sustainability of urban development in Metropolitan Mamminasata, Indonesia.

“…Accordingly, within the SolBio-Rev project, an integrated system for supplying the different thermal and electricity demands of an office building was developed, which relied mainly on solar and biomass energy as sources. The system's architecture and its application to residential buildings were recently published [21], showing the possibility of supporting a strong increase of the share of renewables in residential buildings across Europe. In this paper, the evaluation of the potentialities of this system for providing heating, cooling, DHW and electricity in office buildings in three different climates (Madrid, Berlin, Helsinki) is presented.…”

Increasing the energy efficiency of residential and non-residential buildings is a crucial point towards the development of the sustainable cities of the future. To reach such a goal, the commonly employed intervention measures (for instance, on facades and glass) are not sufficient and efforts in reaching a fully renewable energy generation are mandatory. In this context, this paper discusses the applicability of a system with solar and biomass as the main energy sources in different climates for heating, cooling, domestic hot water and electricity generation in office buildings. The energy system includes solar thermal collectors with thermoelectric generators, a biomass boiler, a reversible heat pump/organic Rankine cycle and an adsorption chiller. The results showed that the system can operate with a share of renewables higher than 70% for all energy needs, with up to 80% of the overall energy demand supplied only by solar and biomass sources even in the northern locations.

“…Palomba et al [12,37] evaluated the application of a hybrid solar-biomass system for heating, cooling, DHW, and electricity production consisting of evacuated tube solar collectors with thermo-electric generators, a cascade sorption-compression heat pump that can work in reverse mode as an ORC (Organic Rankine Cycle) and a biomass boiler. Results of an energy analysis for residential and office applications demonstrated the possibility of achieving a high overall share of renewables (i.e., higher than 70%) at different latitudes (Spain, Germany, Finland).…”

The need for innovative heating and cooling systems to decarbonize the building sector is widely recognized. It is especially important to increase the share of renewables at building level by maximizing self-consumption and reducing the primary energy demand. Accordingly, in the present paper, the results on a wide experimental campaign on a hybrid system are discussed. The system included a sorption module working as the topping cycle in a cascade configuration with a DC-driven vapor compression heat pump. A three-fluids heat exchanger with a phase change material (PCM), i.e., RT4 with nominal melting temperature of 4 °C, was installed on the evaporator side of the heat pump, for simultaneous operation as thermal storage and heat pumping purposes. The heat pump was connected to a DC-bus that included PV connection and electricity storage (batteries). Results showed that the energy efficiency of the heat pump in cascade operation was double compared to compression-only configuration and that, when simultaneously charging and discharging the latent storage in cascade configuration, no penalization in terms of efficiency compared to the compression-only configuration was measured. The self-sufficiency of the system was evaluated for three reference weeks in summer conditions of Athens climate and it was found that up to 100% of the electricity needed to drive the system could be self-produced for a modest cooling demand and up to 67% for the warmer conditions with high cooling demand.
