Special Issue Information

Dear Colleagues,

The energy demand of buildings represents a large share of the total energy demand worldwide, thus, it is of paramount importance to promote and achieve a sustainable built environment. In particular, improving the energy efficiency and exploiting the energy flexibility that buildings can provide improves the overall efficiency of the energy system. The built environment interacts with different energy networks, such as the electricity grid, natural gas grid and thermal networks. In general, buildings can be coupled to multi-carrier energy systems and their inner flexibility can be exploited to optimize the overall energy system in order to make better use of the available resources and achieve a sustainable energy system. There are different kinds of energy demand in buildings, which can be mainly divided into electricity and thermal demand. The energy demand of buildings can be reduced by means of different actions aimed at increasing their energy efficiency. Furthermore, part of the demand is due to the so-called deferrable loads, which can be shifted in time without altering the service provided to the end user (e.g., refrigerators, dishwashers and thermostatically controlled loads).

The focus of this Special Issue concerns the smart management of energy demand in the built environment, which can be realized in different ways, e.g., by refurbishment, use of higher performing energy production devices, introduction of energy storage systems, and proper control strategies. All of these actions can indeed make buildings interact with the energy production system in a more effective way, leading to a more sustainable world.

This paper presents results of work developed in the field of building energy benchmarking applied to the building stock of the Polytechnic Institute of Leiria, Portugal, based on a thorough energy performance characterisation of each of its buildings. To address the benchmarking of the case study buildings, an energy efficiency ranking system was applied. Following an energy audit of each building, they were grouped in different typologies according to the main end-use activities developed: Pedagogic buildings, canteens, residential buildings and office buildings. Then, an energy usage indicator was used to establish a metric to rank the buildings of each typology according to their energy efficiency. The energy savings potential was also estimated, based on the reference building energy usage indicator for each typology, and considering two different scenarios, yielding potential savings between 10% and 34% in final energy consumption.

Tentative title: Analysis of the Methodologic Assumptions of the NOM-020-ENER-2011 Mexican Residential Building Standard
Authors: Ignacio Martin-Dominguez 1, Norma Rodriguez-Muñoz 2,*, Karelly Romero-Perez 1 and Mario,  Najera-Trejo 1 
Abstract: The study of housing in Mexico and throughout the world has been a topic of recent relevance mainly due to increasing energy consumption and environmental issues. Despite government and private efforts to provide quality housing for the increasing demand, the quality of construction and thermal comfort have decreased. In Mexico, social housing lacks thermal comfort and relies on ventilation and air conditioning systems. These concerns have led to the implementation of different regulations. In 2011, the NOM-020-ENER-2011 was published in México as a mandatory procedure to be met for residential buildings. The objective of this standard is to limit heat gains of residential buildings to reduce energy consumption due to cooling systems. This standard was intended to be applied throughout Mexico; however, the standard limits to include four different climatic zones and prioritizes the energy savings due the decrease on the use of cooling systems. As a result, the energy consumption of regions with mild to moderate winters was left with a poorly designed thermal regulation. In this study, technical arguments and deficiencies on several assumptions that produce errors on their application. Equations and calculation assumptions are analyzed, and alternative modifications on the existent methodology are proposed accordingly.

Tentative title: Management of multi-sector and multi-energy systems: a critical analysis

Abstract: The urgent need for reduction of greenhouse gas (GHG) emissions requires efficient and integrated energy communities in order to decrease final energy demand and sustain energy transition towards renewable energy sources (RES). This introduces a big research challenge for future energy systems design and optimization given the multi level and inter-sectorial dimension of the problem. Buildings cover a central role in this context because they represent the nexus between different energy carriers networks. The study of management of multi sector and multi energy systems present several challenges, such as the need to take into account uncertainties, to represent the heterogeneity of the energy demand and the scalability of the problem. This paper aims at outlining such framework and at showing the state of the art about the challenges above mentioned.

Abstract: In this paper the smart management of buildings energy use by means of an innovative renewable microcogeneration system is investigated. The system consists of a concentrated Linear Fresnel Reflectors solar field coupled with a phase change material thermal energy storage tank and a 2kWe/18kWth Organic Rankine Cycle system, as developed by the consortium of several European Universities and industrial organizations, with the funding from EU under the Innova MicroSolar project. More precisely, the microsolar ORC has been designed to supply both electricity and thermal energy demand to several dwellings. In this analysis, the achievable energy savings by the proposed plant with respect to traditional technologies have been assessed for different locations and size of dwellings. In particular, the influence of the climate and latitude of the installation is taken into account to assess the performance and the potential of such system across Europe.
