“…O que caracteriza o setor de serviços é sua grande heterogeneidade em suas atividades, ele possui diferentes subsetores e estes se dividem em outros, com novas particularidades (JAKUBCIONIS; CARLSSON, 2018). Nos últimos anos o setor de serviços se destaca por seu desempenho e atuação na economia brasileira (IBGE, 2017).…”

RESUMOPara alcançar maiores desempenhos junto ao setor de serviços ou em qualquer aspecto organizacional, é importante que ocorram mudanças constantes em busca de melhorias, e nisso se insere a inovação. Desta maneira, a realização de inovações vem a contribuir para o desempenho das organizações. Assim, a presente pesquisa teve como objetivo empregar o método AHP para melhor compreender as ações de inovações em um estudo de multicaso. Realizou-se a pesquisa na região norte do Rio Grande do Sul com três empresas de pequeno porte do setor de serviços (Academia, Boate e Provedora de internet), aplicando o método AHP para priorizar a tomada de decisão das empresas investigadas. Como resultado a Empresa "A" priorizou a liderança e a cultura (25,96%), a empresa "B" destacou a liderança, aprendizagem organizacional e o marketing (19,43%) e a Empresa "C" priorizou a liderança e a aprendizagem organizacional (29,07%). Diante destes resultados, as empresas podem verificar quais são os critérios que estão sendo destacados, mas, além disso, quais são aqueles que não estão recebendo a devida importância. Assim, é possível criar estratégias para melhorar os pontos mais fracos do negócio, gerando maiores resultados. Palavras-chave: Inovação. Serviços. Processo decisório. ABSTRACTIn order to achieve greater performance in the service sector or in any organizational aspect, it is important that there be constant changes in the search for improvements, and this is where innovation is inserted. Innovation comes to contribute to the performance of organizations. Thus, the present research had as objective to use the AHP method to better understand the actions of innovation in a multi-case study. The research was carried out in the northern region of Rio Grande do Sul with three small services companies (a fitness gym, a nightclub and an internet provider), applying the AHP method to prioritize the decision-making of the companies investigated. As result company "A" prioritized leadership and culture (25.96%), company "B" highlighted leadership, organizational learning and marketing (19.43%) and company "C" prioritized leadership and organizational learning (29.07%). Given these results, companies can check which criteria are being highlighted, but also which ones are not being given due importance. Thus, it is possible to create strategies to improve the weak points of the business, generating better results.

“…Hamburg has a temperate oceanic (Cfb), and Murcia a hot semi-arid (BSh) climate, according to the Köppen-Geiger climate classification [44,[234][235][236][237]. Local weather station data from 2012 to 2016 [238][239][240] are used to calculate the five-year average (µ) and annual coefficient of variation (CV, also known as the relative standard variation) of the average annual wind speed, solar global horizontal irradiation, precipitation, air temperature, daily maximum and minimum air temperatures, heating degree days (HDD) [127,241], and cooling degree days (CDD) [50,51].

“…Also, within the respective countries (Spain and Germany), locally, the number of HDDs and CDDs [50,51,308] can differ greatly from the national weighted average [118]. Due to a lack of recent and complete studies on building energy demand relations with respect to climatic parameters, a similar method is developed as in [50,51]. For space heating for both the residential and the services sector, a relation between the specific thermal heating demand and the number of HDDs per country is established using [54,55,118].…”

Renewable, reliable, and affordable future power, heat, and transportation systems require efficient and versatile energy storage and distribution systems. If solar and wind electricity are the only renewable energy sources, what role can hydrogen and fuel cell electric vehicles (FCEVs) have in providing year-round 100% renewable, reliable, and affordable energy for power, heat, and transportation for smart urban areas in European climates? The designed system for smart urban areas uses hydrogen production and FCEVs through vehicle-to-grid (FCEV2G) for balancing electricity demand and supply. A techno-economic analysis was done for two technology development scenarios and two different European climates. Electricity and hydrogen supply is fully renewable and guaranteed at all times. Combining the output of thousands of grid-connected FCEVs results in large overcapacities being able to balance large deficits. Self-driving, connecting, and free-floating car-sharing fleets could facilitate vehicle scheduling. Extreme peaks in balancing never exceed more than 50% of the available FCEV2G capacity. A simple comparison shows that the cost of energy for an average household in the Mid Century scenario is affordable: 520–770 €/year (without taxes and levies), which is 65% less compared to the present fossil situation. The system levelized costs in the Mid Century scenario are 71–104 €/MWh for electricity and 2.6–3.0 €/kg for hydrogen—and we expect that further cost reductions are possible.

“…In addition, Jakubcionis and Carlsson [18] have estimated the European service sector space cooling potential through taking United States (US) consumption data as proxy. By employing this method for the case study, the obtained results (approximately 140 kWh/m 2 /year) are less than 7% different from the results obtained from the application of the proposed methodology.…”

A Simplified Methodology for Existing Tertiary Buildings’ Cooling Energy Need Estimation at District Level: A Feasibility Study of a District Cooling System in Marrakech

In district energy systems planning, the calculation of energy needs is a crucial step in making the investment profitable. Although several computational approaches exist for estimating the thermal energy need of individual buildings, this is challenging at the district level due to the amount of data needed, the diversity of building types, and the uncertainty of connections. The aim of this paper is to present a simplified measurement-based methodology for estimating the cooling energy needs at the district level, which can be employed in the preliminary sizing and design of a district cooling network. The methodology proposed is suitable for tertiary buildings and is based on building electricity bills as historical data to calculate the yearly cooling demand. Then, the developed method is applied to a real case study: the feasibility analysis of a sustainable district cooling network for a hotel district in the city of Marrakech. The designed system foresees a 23-MWcold district cooling network that is 4 km long, supplying 26 GWh of cooling to the tourist area. The results show that the proposed methodology for cooling demand estimation is coherent with the other existing methods in the literature.
