“…Air infiltration is a term commonly used to designate uncontrolled and unintentional air flows through the building envelope, through holes, cracks, voids and unsealed joints. Some authors, particularly in the HVAC literature, distinguish between infiltration and exfiltration to mean the ingress of outdoor air into the building and the escape of indoor air out of the building, respectively [20], [21].…”

Highlights Summary of recent developments and work at ADAI's Energy, Environment and Comfort research group is presented  The Indoor Live Lab (I2L) and an e-learning course on Indoor Environmental Comfort in Buildings are introduced  The paper aims to present the facilities, instruments and the purposes behind I2L project  Several Indoor Environmental Quality (IEQ) parameters studies are discussed in particular 1 AbstractIn this paper some of the recent developments and ongoing work at the Energy, Environment and Comfort research group of ADAI (Association for the Development of Industrial Aerodynamics), in the areas of Indoor Environmental Quality and Energy Efficiency in Buildings are presented. Summarily, it is showcased a state of the art of the Indoor Live Lab, developed at the Mechanical Engineering Department of the University of Coimbra. The Indoor Live Lab (I2L) is a new platform for research and technology demonstration in IndoorEnvironmental Quality (IEQ). The main motivation for initiating this effort arose from the increasing necessity that researchers, educators and decision makers have for continuously available monitored data on all aspects of building functioning. This paper aims at presenting early developments at the I2L, as well as associated research projects which were at the centre of its creation. Firstly, the objectives of the I2L are presented. Secondly, ongoing research on both residential buildings and services buildings is exposed. After, the several IEQ parameters studies are discussed in particular. This is followed by the I2L description, location and specific features. Finally, a conclusion and future work section is presented.

“…It is often argued that, as this large stock is to cater for the increase in population, a large proportion end up consuming more energy, thereby negatively affecting the environment [12]. Unfortunately, these buildings are associated with several defects such as cracks [13], corrosion of steel components in old buildings [14], heat losses because of poor insulation [15], highly unclassified [16], high level of air infiltration [17], and leakages [18]. The leakages can be attributed to differences in design and workmanship [19].…”

Abstract:Globally, only 2% of existing building stock is built yearly; the remaining 98% already exist. Energy consumption and indoor thermal comfort of the existing building stock are not encouraging. This is due to many challenges associated with existing buildings; the challenges range from cracks, leakages, poor insulation, heat losses and high rate of unsustainable technologies. This paper investigates possible barriers facing the adoption and application of sustainable technologies (STs) for sustainable or energy-efficient upgrade of existing buildings. New STs are manufactured on a regular basis to meet improved energy efficiency standards, yet there are minimal actions/attempts to adopt and apply improved technologies in existing buildings for energy efficiency. Indeed, there are limited studies focused on the use of qualitative approaches to identify barriers to adoption and use of STs. Thus, a semi-structured interview approach was adopted and applied using sustainability/energy efficiency professionals, building services engineers, project managers, architects, and facility managers in Australia. The results indicate that barriers to the adoption and application of sustainable technologies are perceived benefits in demolish-and-build, age of building, cost of STs, perceived poor payback time, unreliable energy-savings projections, existing design, hidden and overall cost of renovation, and cost of STs.

“…The solution space is also characterized by discontinuities and non-linearity, with discrete and continuous variables existing together [20][21][22]. As a result of the size of the solution space, it is impossible to check all possible combinations.…”

Abstract:This study suggests an optimization method for the life cycle cost (LCC) in an economic feasibility analysis when applying energy saving techniques in the early design stage of a building. Literature and previous studies were reviewed to select appropriate optimization and LCC analysis techniques. The energy simulation (Energy Plus) and computational program (MATLAB) were linked to provide an automated optimization process. From the results, it is suggested that this process could outline the cost optimization model with which it is possible to minimize the LCC. To aid in understanding the model, a case study on an industrial building was performed to outline the operations of the cost optimization model including energy savings. An energy optimization model was also presented to illustrate the need for the cost optimization model.
