Getting cities and communities smarter is a strategic but also very complex process that involves several actors (e.g., governments, industries, scientific researchers) and addresses many challenges. Among these, energy efficiency and cost-saving are indispensable. Following this line, in this paper we propose a novel energy-aware management system, we name Energy Saving Smart Building (ESSB), for smart environments. More specifically, we present its experimental use at University of Messina\ in order to optimize the use of all the electrical equipments. The results are the reduction of energy consumptions and costs improving comfort and sustainability in smart office environments.\

Cloud federation offers new business models to enforce more flexible energy management strategies. Typically, an independent Cloud provider is exclusively bounded to the specific energy supplier powering its data center. The situation radically change if we consider a federation of cooperating Cloud providers. In such a context a proper migration of virtual machines among providers can lead to global energy sustainability and cost-saving strategies.\ 
In this paper, we discuss a decision algorithm, for Cloud federation brokerage, able to combine these two strategies. More specifically, we present a Multi-Criteria Decision Making (MCDM) algorithm able to discover the most convenient Cloud provider candidates to join a particular energy-aware federation. In the end, by modelling different possible real Cloud providers, we demonstrate how the algorithm can accommodate different Cloud federation scenarios characterized by particular energy-aware parameters.

The advent of both Cloud computing and Internet of Things (IoT) is changing the way to conceive distributed systems. Nowadays, we can talk about IoT Cloud to indicate a new type of distributed system consisting of a set of smart IoT devices or sensors interconnected with a remote Cloud infrastructure, platform, or software. Energy sustainability in IoT Cloud providers offers new tempting business opportunities for organizations, but at the same time it raises new challenges. In this paper, a flexible IoT Cloud federation energy management strategy is presented for optimizing the allocation of geographically localized smart sensors. We define the concept of IoT Cloud Federation as a mesh of IoT Cloud providers that are interconnected to provide a universal decentralized sensing and actuating environment where everything is driven by constraints and agreements in a ubiquitous infrastructure.\ In particular, a dynamic algorithm able to improve energy sustainability in a federated IoT Cloud ecosystem is discussed. In addition, we analyze a use-case driven strategy that allows both IoT Cloud providers and brokers to determine the paths to reach possible destination IoT devices in which computational resources should be dynamically migrated in order to push down the energy consumption due to IoT distributed applications.

Cloud federation is paving the way toward new business scenarios in which it is possible to enforce more flexible energy management strategies than in the past. Considering independent cloud providers, each one is exclusively bound to the specific energy supplier powering its datacenter. The situation radically changes if we consider a federation of cloud providers powered by both a conventional energy supplier and a renewable energy generator. In such a context, the opportune relocation of computational workload among providers can lead to a global energy sustainability policy for the whole federation. In this work, the authors investigate the advantages and issues for the achievement of such a sustainable environment.
