A Reflection on Low Energy Renovation of Residential Complexes in Southern Europe

Abstract:The transformation of European existing building stock towards very low energy buildings requires a new approach. In this context, it seems reasonable to think that buildings should no longer be renovated individually but as part of a global energy system. Focusing on larger urban units may present some scale advantages and may constitute an opportunity to change the urban environment in a smart energy way. Specificities of Southern European countries are addressed. Due either to the climate or the life style, there are large differences in energy consumption per dwelling among southern and northern European countries. How much heating energy will be saved by over-insulating building envelopes if people do not feel the need to heat their houses in the first place? In addition, real energy use in buildings frequently shows major differences with respect to the predicted consumption. The definition of realistic solutions demands the availability of realistic predictions. A case of a residential complex in Portugal is used to illustrate the main questions and to conclude that moving from a building to a group of buildings scale may be an interesting challenge for policy makers to look closer in the near future.

“…Studies of the optimization of energy systems in mixed‐use buildings are available in the literature; however, there is still a lack of studies focusing on integrated renewable‐storage energy solutions, especially for grid‐connected buildings. Two previous studies have investigated the potential of solar photovoltaic (PV) systems for mixed‐use buildings but integrated the RE source with natural gas 10 and waste‐to‐energy (WtE) 11 systems that are only applicable to certain mixed‐use combinations. Other studies also proposed solutions for specific types of mixed‐use buildings, such as commercial data center, 12 and retail greenhouse 13 .…”

Optimal design of an integrated renewable‐storage energy system in a mixed‐use building

The rise of mixed-use buildings contributes to the sustainable development of cities but are still met with challenges in energy management due to the lack of energy efficiency and sustainability guidelines. The use of integrated renewable-storage energy systems is a more beneficial solution to this problem over individual solutions; however, most design studies only focused on singletype buildings. Thus, this study aims to optimally design an integrated energy system for mixed-use buildings using HOMER Grid. The objective is to minimize the net present costs, subject to capacity limits, energy balances, and operational constraints. Economic metrics were used to evaluate and compare the proposed system to the varying design cases such as business-as-usual, stand-alone renewable source, and stand-alone energy storage. The case study considered a mixed-use building in a tropical area, with a solar photovoltaic system as the renewable energy source and lithium-ion battery as the energy storage system technology. The results show that the integrated system is the most financially attractive design case. It has a levelized cost of electricity of 0.1384 US$ kWh −1 , which is significantly less than the 0.2580 US$ kWh −1 baseline. The system also provides electricity cost savings of 294 698 US$ y −1 , excess electricity of 35 746 kWh, and carbon emission reduction of 550 tons annually for a mixed-use building with daily average consumption of 4557-kWh and 763-kW peak demand.

“…In the opposite situation, the building acts as a traditional energy consumer. The PV is the most common technology applied for distributed energy generation at the single building and community level (Hachem-Vermette, Cubi, & Bergerson, 2016;Mohamed, Hamdy, Hasan, & Sirén, 2015;Rahmani-Andebili, 2017;Voss & Musall, 2012;Widén, Wäckelgård, Paatero, & Lund, 2010b) and in Denmark the PV combined with the HP is the cost-optimal configuration of residential energy supply system (H. Lund, Marszal, & Heiselberg, 2011;Marszal, Heiselberg, Lund Jensen, & Nørgaard, 2012;Milan, Bojesen, & Nielsen, 2012). In this sense, the electricity consumption or generation technologies selected at the domestic level can be combined in different ways to define a prosumer or non-prosumer, i.e.…”

Prosumers have a different interaction with the distribution network in comparison with traditional consumers. They have a bi-directional power exchange with the grid, meaning they receive from as well as deliver electricity to the network. The emergence of prosumers is expected to challenge the way network operators control the residential low-voltage (LV) distribution networks. Commonly, the metering of received and delivered electricity at the residential level is conducted on 1-hour basis, thus only hourly load/generation profiles are available for the system operators to conduct the power system impact analysis. Yet, it is relatively difficult to have an accurate prediction of the real system performance if the intra-hour phenomena are not considered. A better estimation requires employment of higher temporal resolution profiles during the power system studies. To address these challenges, which future smart cities and communities might face, this paper presents a methodology for generating 1
