“…The global energy consumption is estimated to increase between 2010 and 2040 by 56% (U.S. Department of Energy, 2016). Despite the decreasing coal, petroleum and natural gas resources, and all the issues their appliance evoke (such as global warming and climate change), in 2015, the share of fossil fuels was 78.4% of the final global energy consumption, while renewables and nuclear power considering the advantage that the energy is then being produced close to the location where it is needed (Xydis, 2015;Xydis and Mihet-Popa, 2016;Stathopoulos et al, 2018).…”

The development in the field of wind turbines is continuously growing. However, most of the times, the energy of wind is exploited by using huge wind-power plants, while wind energy installations in urban and suburban areas, as space and available land, are a lot more limited, is something relatively new, with great potential though. The major challenge regarding small urban wind turbines can be summarized as a lack of understanding of the wind resource in the built environment, with a combination of missing measurements in this field that needed to be addressed. Aarhus University Campus Herning, located in the suburban area of Herning, is looking for a suitable place to install one small wind turbine (SWT). This study attempts to provide a comprehensive framework for SWTs and the characteristics of urban wind flow. The analysis helped in identifying the two most appropriate sites for SWTs installation sites in the AU Herning building.

“…Similar studies were also found in the literature focused on autonomous buildings and isolated grids. 8,9 Based on the assumption that end-users are unwilling or unable to alter their electricity consumer behaviour, operation and management supply side draws more attention than the demand, in most traditional power systems. As a result, there are higher generation expenses for the operator coming from the operation of expensive conventional plants committed to contribute only at peak times (demand is usually met by lower cost base load units, during off-peak periods).…”

The main aim of this work is to reduce electricity consumption for consumers with an emphasis on the residential sector in periods of increased demand. Efforts are focused on creating a methodology in order to statistically analyse energy demand data and come up with forecasting methodology/pattern that will allow end-users to organize their consumption. This research presents an evaluation of potential Demand Response programmes in Greek households, in a real-time pricing market model through the use of a forecasting methodology. Long-term Demand Side Management programs or Demand Response strategies allow end-users to control their consumption based on the bidirectional communication with the system operator, improving not only the efficiency of the system but more importantly, the residential sector-associated costs from the end-users’ side. The demand load data were analysed and categorised in order to form profiles and better understand the consumption patterns. Different methods were tested in order to come up with the optimal result. The Auto Regressive Integrated Moving Average modelling methodology was selected in order to ensure forecasts production on load demand with the maximum accuracy.

“…Whilst there is a large body of work describing the use of TES systems for demand-side management (see review by Sun et al 2013), only two recent studies detail the impact of integrated control of PV and ice thermal energy storage using energy modelling tools (Wang and Dennis 2015;Sehar et al 2016) and one described the use of surplus wind energy and thermal storage (Xydis and Mihet-Popa 2016). This study is unique as it examines an end-user-operated direct digital control (DDC) BMS that controls HVAC with integrated chilled water TES, and the chilling of a large 3.2-ML aquarium tank, in order to optimise solar PV energy generation use in the absence of electrical battery storage.…”

Reef HQ Aquarium is a major tourism attraction in tropical North Queensland, Australia. In 8 years, a 50% reduction in grid electricity was achieved through targeted infrastructure investment, whilst growing the business. Initially, grid energy consumption was 2438 MWh per annum, with 490-kW peak demand and energy intensity of 1625 MJ m −2 year −1 used on typical equipment such as HVAC (heating, ventilation and air conditioning), machinery, lighting and catering equipment. Savings of 13% were achieved in the first year by increasing indoor air temperature set-points by 1.5°C with no significant costs or impacts on occupant thermal comfort or worker productivity. Peak demand was decreased by 46% by upgrading the computerised building management system (BMS), HVAC, machinery and lighting; and by installing a 206-kW photovoltaic (PV) solar power system. This case study illustrates that (a) significant energy use reductions are possible at low cost; (b) capital investment in energy-efficient infrastructure can have short payback times and high direct and indirect benefits, particularly where equipment is ending its life. This study is unique as it examines how a commercial building with integrated chilled water thermal energy storage (TES) and a 3.2-ML chilled seawater aquarium system can be controlled by a BMS to optimise solar power to manage peak energy demand and also increase the utilisation of generated PV power in the absence of electrical battery storage. An interesting building is used to demonstrate efficiency methods with elements such as HVAC and lighting which usually consume over half commercial buildings' energy use.
