Building Energy Optimization

Increasing energy demand in buildings with a 40% global share and 30% greenhouse gas emissions has accounted for climate change and a consequent crisis encouraging improvement of building energy efficiency to achieve the combined benefit of energy, economy, and environment. For an efficient system, the optimization of different design control strategies such as building space load, occupancy, lighting, and HVAC becomes inevitable. Therefore, interdisciplinary teamwork of developers, designers, architects, and consumers to deliver a high-performance building becomes essential. This review aims to endorse the importance of Building Performance Simulation in the pre-design phase along with the challenges faced during its adaptation to implementation. A morphology chart is structured to showcase the improvement in Building Energy Efficiency by implementing Building Performance Simulation for different building energy systems and by implementing various energy efficiency strategies to achieve the 3E benefit. As a developing nation, India still lacks mass application of Building Performance Simulation tools for improving Building Energy Efficiency due to improper channelizing or implementation; thus, this framework will enable the designers, architects, researchers to contemplate variable building energy optimization scenarios.

The Impact

Energy demand reduction in buildings is an important measure to achieve climate change mitigation. It is essential to minimize heat losses in designing phase in accordance of building energy efficiency. For building energy efficiency in a mild climate zone, a large part of the heating demand is caused by transmission losses through the building envelope. Building envelopes with high thermal resistance are typical for low-energy buildings in general. In this sense thermal bridges impact increases by using of greater thickness of thermal insulation. This paper is focused on thermal bridges minimizing through typical system details in buildings. The impact of thermal bridges was studied by comparative calculations for a case study of building with different amounts of thermal insulation. The calculated results represent a percentage distribution of heat loss through typical building components in correlation of various thicknesses of their thermal insulations.

User Perception

Energy demand in buildings can reduce by improving energy efficiency. MS1525 has recommended that energy efficiency for Non-Residential Buildings in Malaysia to be not more than 135kWh/m²/year. A school building is a non-residential building and has major social responsibilities. Based on the theory of building energy-efficiency, energy efficiency can be achieved through three main factors: a) design of buildings; b) design of services; and c) user behavior. This study aims to investigate the user perceptions in High-Performance Schools. Keywords: User perception; building energy index; building energy efficiency; school building. eISSN 2514-7528 © 2018.

AbstractWe investigate the relationship between building energy efficiency and the probability of mortgage default. To this end, we construct a novel panel data set by combining Dutch loan-level mortgage information with provisional building energy ratings provided by the Netherlands Enterprise Agency. Using the logit regression and the extended Cox model, we find that building energy efficiency is associated with a lower probability of mortgage default. There are three possible channels that might drive the results: (i) personal borrower characteristics captured by the choice of an energy-efficient building, (ii) improvements in building performance that could help to free-up the borrower’s disposable income, and (iii) improvements in dwelling value that lower the loan-to-value ratio. We address all three channels. In particular, we find that the default rate is lower for borrowers with less disposable income. The results hold for a battery of robustness checks. This suggests that the energy efficiency ratings complement borrowers’ credit information and that a lender using information from both sources can make superior lending decisions than a lender using only traditional credit information. These aspects are not only crucial for shaping future energy policy, but also have implications for the risk management of European financial institutions.

In recent years, energy crisis increases, energy saving and environment protection have become particularly important. With the improvement of people's living standards, energy demand is increasing; therefore, building energy conservation is imminent.Building energy efficiency needs much attention and implementation, which covers construction units, design units and supervision units. Construction of the building energy efficiency is full of the entire construction process. From planning, design, construction to supervision process is all in control. The lack of a link monitoring is likely to result in an increase in energy consumption. Resource engineering supervision is an important construction implementation process, and is an important link in the process of building energy conservation monitoring.Building energy conservation.

Architectural Models

<p>Designers from the Architecture, Engineering, and Construction (AEC) industries have shown a desire to allow for quantitative data to back up sustainable decision-making (Braasch, 2016). Methods and software used to reach this goal often do not provide all the information to make informed design decisions or require a complete remodelling of designs at each stage. These factors make Building Performance Simulation (BPS) feasible at early design stages, where it is most beneficial for Architects.  This thesis explores the current process to translate Architectural models constructed within a Building Information Modelling (BIM) environment into Building Energy Models (BEM) so that performance simulations can take place. Within the aim of exploring translation processes, the objectives were to document:  • Whether current processes can facilitate modelling of environmental building performance during early design, as well as during developed design?  • Whether there are any common problems or successful approaches that might form the basis of future improvements in the way Architect’s and consultant’s models work together?  This thesis has identified 19 translation processes from current literature and examined a range of representative processes for exchanging information between Architectural modelling and BPS programs. It concluded that translation issues can be classified into similar groups based on the overall processes used. The eight categories of issues can be used by future developers to determine their priorities in development, and those looking for a current solution can adopt one for themselves. None of the processes tested allowed for issue-free modelling of building performance during sketch design.  The two types of building translation schema evaluated in this thesis divided identified references between a dedicated and generalised approach. The dedicated approach of gbXML and the generic approach of IFC identified similar issues; however, IFC contained more of these problems because it communicates with all modelling programs at a lower information quality. Due to the generic approaches containing more issues that take longer to solve, it is currently more complicated to generate an energy model out of IFC data. While the gbXML schema can only provide benefits for BPS related translations, it is the most viable way to provide the service.</p>
