The “Smart Cities & Communities Initiative” of the Strategic Energy Technology Plan is the strategic European response to lead cities and regions to a carbon free future. In this contest energy efficiency in buildings has a crucial role and must be considered in a holistic approach to the urban planning. In order to implement the minimum requirements stated by the European Directive about the Energy Performance of Buildings, and in order to consider different planning layers with the view to a smart city planning, local regulations are a key factor aiming at sustainable territorial planning. This paper investigates the possibility to draft a basic structure of Municipal Building Regulations in order to guide local administrators and technicians and to limit discretionary power of bureaucracy. The paper is organized as follows. First, a review of the most common practices for building regulations in Europe is proposed, then the basic structure of a municipal building regulation for the city of Palermo (Southern Italy) accounting for sustainability is discussed.

The assessment of building energy performance requires data from multiple domains (energy, architecture, planning, economy) and scales (building, district, city) to be processed with a diversity of applications used by experts from various fields. In order to properly assess the performance of the building stock, and to develop and apply the most effective energy efficiency measures, it is necessary to adopt a comprehensive, holistic approach. In this chapter, three research projects are presented which apply Semantic Web technologies to create energy data models from multiple data sources and domains in order to support decision making in energy efficient building renovation projects: SEMANCO, OptEEmAL, and OPTIMUS. A final reflection on the results achieved in these projects and their links to ongoing research on digital twins is presented.

Energy-efficiency is one of the critical issues in smart cities. It is an essential basis for optimizing smart cities planning. This study proposed four new artificial intelligence (AI) techniques for forecasting the heating load of buildings’ energy efficiency based on the potential of artificial neural network (ANN) and meta-heuristics algorithms, including artificial bee colony (ABC) optimization, particle swarm optimization (PSO), imperialist competitive algorithm (ICA), and genetic algorithm (GA). They were abbreviated as ABC-ANN, PSO-ANN, ICA-ANN, and GA-ANN models; 837 buildings were considered and analyzed based on the influential parameters, such as glazing area distribution (GLAD), glazing area (GLA), orientation (O), overall height (OH), roof area (RA), wall area (WA), surface area (SA), relative compactness (RC), for estimating heating load (HL). Three statistical criteria, such as root-mean-squared error (RMSE), coefficient determination (R2), and mean absolute error (MAE), were used to assess the potential of the aforementioned models. The results indicated that the GA-ANN model provided the highest performance in estimating the heating load of buildings’ energy efficiency, with an RMSE of 1.625, R2 of 0.980, and MAE of 0.798. The remaining models (i.e., PSO-ANN, ICA-ANN, ABC-ANN) yielded lower performance with RMSE of 1.932, 1.982, 1.878; R2 of 0.972, 0.970, 0.973; MAE of 1.027, 0.980, 0.957, respectively.

As energy efficiency is becoming an increasingly important feature, buildings are expected to comply with several criteria and requirements and these criteria are changed and extended with time. The Directive 2002/91/EC of the European Parliament and Commission on the energy performance of buildings and the Directive 2010/31/EU request Member States to apply minimum energy performance requirements. These minimum requirements are indeed applied all over the European Union and should be regularly reviewed. Our research aimed at clarifying whether optimum cost and/or energy efficiency represents the next step towards actual energy efficiency. The Directive brought forth an aspect that should have been prioritized long ago already: Are the construction and refurbishment of buildings in Europe economically feasible? The methodology prescribed by the Directive leaves several questions open and provokes further research. The methodology uses costs only as the basis for examining energy consumption and emissions related to already existing, newly constructed or refurbished buildings or refurbishment options. Optimum cost does not necessarily correspond to optimum energy or environmental performance. The price of materials and equipment built in does not always reflect the energy built in or environmental advantages. Subsidies to promote energy efficiency may bias optimum costs. Viewing optimums from the broader aspect of energy consumption, proper results are only yielded by analyses completed for the entire life cycle of buildings. This way, we may decide which characteristics attribute more to a low energy and emission status, i.e. state-of-the-art construction technology or traditional, natural constructing methods such as those used for „conservative eco buildings.” [1]

Energy-poverty (EP) must be considered an energy-related issue since buildings are a central part of people’s daily lives. Thus, it has an important role in energy-related policy implementation. Even though the European Union (EU) has endorsed general energy efficiency through the Energy Efficiency Directive and Energy Performance of Buildings Directive recast, it was the Clean Energy Package for all Europeans that clearly highlighted EP. The growing concerns with EP have also been emphasised in subsequent directives and initiatives. Despite some regulatory framework and the milder climate situation, the proportion of the population experiencing thermal discomfort in southern and eastern European countries, namely in the winter season, is relatively high, reflecting the poor thermal performance of building stock, low family incomes and high energy prices, among others. The current work analysed the EP evolution in Portugal in the EU context, and the Thermal Building Regulations and Energy Efficiency Policies developed, aiming to add insight into the effectiveness of those policies concerning EP mitigation in Portugal as an EU Member state. Moreover, a critical debate on the potential to lower the EP Portuguese situation was also an objective to pursue. It is plausible to admit that reducing EP by acting on residential building stock, namely through the increase of energy efficiency and comfort, plays a key role in improving the living conditions, namely of vulnerable households and deprived areas. This will also decrease energy consumption and dependence while further promoting a smarter, sustainable and inclusive society, contributing to economic growth.

This chapter is dedicated to business models for green retrofitting on a more holistic approach that enables to think and integrate the economic, social and environmental perspective in a business model. The chapter is a result of research regarding new business models for green retrofitting and presents a framework for developing business models for green retrofitting in the building sector based on the Triple-Layer Business Model Canvas. The business models for green retrofitting could be an important instrument for introducing new green characteristics such as energy efficiency, optimal energy performance, and new comfort standards in the building environment. Green retrofitting is responding to the dynamics of the economic and technological development, and to the new lifestyle of the peoples. The implementation of such a model will be also a catalyst for reducing the emissions of greenhouse gases in the building environment.

Purpose The purpose of this paper is to evaluate long-term effects of previous policies for energy efficiency on energy performance and heritage values. A further ambition is to better understand the relationship between energy and preservation by exploring a quantitative method of combining energy performance data with official heritage designation. Design/methodology/approach The study is based on a quantitative analysis of energy performance, completed additional insulations, and official heritage classification for individual buildings. Data have been collected and analysed for a sample consisting of 289 multi-family buildings heated with district heating and constructed 1940–1949 in an urban area in Stockholm, Sweden. Findings The data exhibit a significant correlation between the studied features. The study further shows that additional insulation has been installed in roughly half of the buildings. The large majority of them were carried out in the national programme for home improvement called ROT. Research limitations/implications The findings indicate that previous policies for energy efficiency had an important effect on energy performance and heritage values in the studied area. They continue to affect urban planning and building permit administration today. Research of the physics of individual buildings would be needed in order to determine the reason for differences in the sample. Originality/value By presenting a novel method, the study provides a useful tool for policy makers to bridge the gap between issues of energy and preservation and adopt a more holistic approach towards a sustainable built environment.

The number of buildings renovated following the introduction of European energy-efficiency policy represents a small number of buildings in Spain. So, the main Spanish building stock needs an urgent energy renovation. Using passive strategies is essential, and thermal characterization and predictive tests of the energy-efficiency improvements achieving acceptable levels of comfort for their users are urgently necessary. This study analyzes the energy performance and thermal comfort of the users in a typical Mediterranean dwelling house. A transient simulation has been used to acquire the scope of Spanish standards for its energy rehabilitation, taking into account standard comfort conditions. The work is based on thermal monitoring of the building and a numerical validated model developed in TRNSYS. Energy demands for different models have been calculated considering different passive constructive measures combined with real wind site conditions and the behavior of users related to natural ventilation. This methodology has given us the necessary information to decide the best solution in relation to energy demand and facility of implementation. The thermal comfort for different models is not directly related to energy demand and has allowed checking when and where the measures need to be done.

This study quantified the improvement in energy efficiency following passive renovation of the thermal envelope in highly inefficient residential complexes on the outskirts of the city of Madrid. A case study was conducted of a single-family terrace housing, representative of the smallest size subsidized dwellings built in Spain for workers in the nineteen fifties and sixties. Two units of similar characteristics, one in its original state and the other renovated, were analyzed in detail against their urban setting with an experimental method proposed hereunder for simplified, minimal monitoring. The dwellings were compared on the grounds of indoor environment quality parameters recorded over a period covering both winter and summer months. That information was supplemented with an analysis of the energy consumption metered. The result was a low-cost, reasonably accurate measure of the improvements gained in the renovated unit. The monitoring output data were entered in a theoretical energy efficiency model for the entire neighborhood to obtain an estimate of the potential for energy savings if the entire urban complex were renovated.
