Comment améliorer la performance énergétique des bâtiments résidentiels et commerciaux ? Comment réduire leurs coûts d'exploitation ? Ce guide technique d'audit énergétique offre une approche systématique et propose des outils et procédures efficaces pour effectuer les analyses énergétiques pour des bâtiments nouveaux et existants : analyse économique, modèles de simulation énergétique, méthodes pour la conception des bâtiments à haute performance énergétique, approches générales pour l'audit énergétique des bâtiments existants. Il donne des exemples concrets pour calculer l'efficacité énergétique selon plusieurs techniques et technologies qui permettront d'améliorer les performances du bâti, des systèmes électriques, du système de chauffage et de climatisation. Par ailleurs, il propose des méthodes de gestion des bâtiments ainsi que des protocoles pour mesurer et vérifier les performances réelles des bâtiments.

Optimal Design and Retrofit of Energy Efficient Buildings, Communities, and Urban Centers presents current techniques and technologies for energy efficiency in buildings. Cases introduce and demonstrate applications in both the design of new buildings and retrofit of existing structures. The book begins with an introduction that includes energy consumption statistics, building energy efficiency codes, and standards and labels from around the world. It then highlights the need for integrated and comprehensive energy analysis approaches. Subsequent sections present an overview of advanced energy efficiency technologies for buildings, including dynamic insulation materials, phase change materials, LED lighting and daylight controls, Life Cycle Analysis, and more. This book provides researchers and professionals with a coherent set of tools and techniques for enhancing energy efficiency in new and existing buildings. The case studies presented help practitioners implement the techniques and technologies in their own projects.Introduces a holistic analysis approach to energy efficiency for buildings using the concept of energy productivityProvides coverage of individual buildings, communities and urban centersIncludes both the design of new buildings and retrofitting of existing structures to improve energy efficiencyDescribes state-of-the-art energy efficiency technologiesPresents several cases studies and examples that illustrate the analysis techniques and impact of energy efficiency technologies and controls

This study investigates the optimal retrofitsolutions for residential communities to be carbon neutral in Barcelona, Spain. The residential building stock in these communities includesthree prototypical dwelling types: detached, attached, and apartment.In this study, three different sizes for the residential communities are considered depending on the number of housing units: small, medium, and large. First,the bestcost-effectiveenergy efficiency measures (EEMs) have been determinedand applied to allthe buildings of thecommunities, in order to reduce their overallenergy demand.The retrofit optimization results demonstratethat combinationsof passive and active strategies would achieve source energy use saving and electrical peak demandsavings up to 57% and 29%, respectively.Then, a variety of renewable energy generation systems has been explored to determinetheoptimal grid-connected technologiesfor meeting the electricity demandswhile achieving annual carbon neutral conditions for the residential buildings. The analysis results indicatethatcurrently,wind turbines would be the most cost-effectiverenewable generation systems for the residential communities in Barcelona to be carbon-neutral. Specifically, the analysis shows that wind turbines can reduce the cost of electricity generationup to 21.5%compared tothe currentutilityprices (LCOE value as 0.247 €/kWh) and electricity sell back policies. The results indicate that for PV systems tocompetewith wind turbines, their capital costs need to be lower by at least 40% compared to the current level costs, Outgoing
