Special Issue Information

Dear Colleagues,

It is my great pleasure to invite you to submit your most recent research on the assessment of energy-related aspects in buildings to this Special Issue.

Even though the attention given to energy consumption in buildings and building construction has increased over the last years to the point that zero energy buildings represent the target for policies in many countries, improvements are still not keeping up with the growing buildings sector and rising demand for energy services at a global level.

Technical and policy measures in order to encourage energy efficiency and the use of renewables during the different life cycle phases of a residential, commercial or service building (product, construction, use and end-of-life) remain the main challenges, not only in developing countries.

In order to identify opportunities for dealing with these challenges and improving the energy-related aspects associated with the building sector, better energy data for benchmarking as well as tools for assessment are needed. In addition, when used to design decision support and optimization processes, both the data and results should be accurate enough to avoid misleading design decisions and to improve optimization steps.

The aim of this Special Issue is to gain knowledge about recent indicators and procedures proposed for the energy assessment of buildings. One of the most interesting aspects is their feasibility, for instance with regard to ensuring the adequacy and persistence of energy efficiency savings in the whole life cycle of the building, in evaluating installations and actions related to smart energy management, or in modelling the energy behavior of new and existing buildings under different perspectives. The use of building energy assessment methods in a regulatory context for the enhancement of incentives, financing and market mechanisms (energy certification schemes, environmental labelling and rating, etc.) is also a relevant matter.

These are just some of the topics that this Special Issue will try to address, but clearly we are aware that the theme opens multiple approaches to different areas of building energy analysis, including model calibration, life cycle analysis, building stock analysis, impact and adaptation to climate change, sensitivity analysis, spatial analysis and optimization.

It is believed that this Special Issue can contribute to the design and implementation of energy efficiency policies in buildings thanks to the generation of consistent and reliable energy data as the International Energy Agency suggests.

Occupant behavior is recognized as a major source of discrepancy between simulated and actual energy consumption. This study investigates the uncertainty of energy and economic performance of manual solar shades for the south facade. A developed stochastic model for manual solar shades based on a discrete-time Markov chain method was constructed in Building Controls Virtual Test Bed (BCVTB) for co-simulation with EnergyPlus. The stochastic shade model was compared with deterministic models concerning energy savings potential and life cycle economic performance at different building scales (i.e., from a single room to a whole building). The results show that annual energy uncertainty, due to occupant behavior, on manual shades can be neglected at the building level, whereas for sizing heating equipment, energy uncertainty should be considered. The payback period for manual shades is about 10 years and, in general, a larger building has a higher economic performance. Comparative analysis shows that there is a relatively big performance overestimation or underestimation by commonly used deterministic models in building simulation tools, and thus may lead to a biased economic analysis or even an inappropriate design decision when comparing different energy-saving measures.

In recent decades, the international scientific debate has focused on maximizing the energy performance of the building organization during the operational phase. However, the energy performance is only partially in line with the strategic environmental objectives defined by the European Commission which, with Communication 2003/302, also defined the guidelines for the drafting of the National Action Plans on Green Public Procurement (NAP GPP). Law no. 296 of 27 December 2006 provided for “... the implementation and monitoring of an Action Plan for the environmental sustainability of public administration consumption”, drawn up by the Ministry of the Environment and the Protection of Land and Sea. This work moves in the direction of identifying design strategies, relating to construction and urban restructuring, compatible with the criteria of energy and environmental sustainability provided for in the New Code of Public Procurement (Legislative Decree 50/2016), in accordance with the directives of the European Community. The parameters that define the methodological articulation (choice of case studies, scope of reference of stakeholders, etc.) orient the use of the results towards similar cases, i.e. design of urban districts located in regions with a Mediterranean climate.

The criticality related to the consumption of operational energy and related greenhouse gas (GHG) emissions of existing buildings is clearly decreasing in new buildings due to the strategies tested and applied in recent years in the energy retrofit sector. Recently, studies have been focusing on strategies to reduce environmental impacts related to the entire life cycle of the building organism, with reference to the reduction of embodied energy (and related greenhouse gas emissions) in building materials. As part of EEA’s European EBC project, Annex 57, a wide range of case studies have been promoted with the aim of identifying design strategies that can reduce the embodied energy and related greenhouse gas emissions of buildings. The aim of this paper is to investigate the most common construction systems in the construction industry (concrete, steel, wood) through the analysis of three contemporary architectural works, with the aim of identifying the predisposition for environmental sustainability of each technological system, thus guiding the operators in the sector towards design choices more compatible with the environmental requirements recommended by European legislation.
