Difficult Challenge

Leadership in Energy and Environmental Design (LEED) is a national set of standards put forth by the U. S. Green Building Council in 1994 that was intended to inspire building designers to plan greener, more sustainable buildings. LEED offers up to ten points for improved energy optimization performance. It should be noted that achieving these ten points is time consuming, complex, and expensive. This research is a case study that details the process of using a computer simulation study as a building energy optimizing tool in order to achieve these optional points. Determination is made as to how many LEED points can be obtained when basic strategies such as window performance and day-lighting are integrated into one energy optimized building design. The results show that well-established energy conservation methods achieve as few as two or three LEED energy points, thereby possibly offering a disincentive for designers to attempt this difficult challenge. These fundamental efforts to achieve energy optimized building design are the first steps toward high performance building design and offer a fundamental solution to the substantial, negative environmental impacts caused by buildings today.

Many university campuses in the United States are working toward their sustainable goals by adopting energy or green building policies, which require Leadership in Energy and Environmental Design (LEED®) certification for new construction and major renovation projects. Because LEED certification heavily relies on whole building energy simulation to demonstrate building energy performance improvement, it is often assumed that the finished buildings will achieve the predicted level of energy efficiency. This paper presents a study that compares the energy model predictions with actual energy performance of three LEED buildings on a university campus. The study shows that one of the campus LEED buildings consumed twice the predicted energy usage while causing a high level of occupant dissatisfaction. Further investigation reveals a variety of contributing factors for these issues and provides insights to improve green building policy and practice. Not only are the research findings important for this particular campus (Ohio State University) on its way to sustainability, they also have widespread ramifications for other university campuses.

This is a case study on the Magic school of Green Technology (MSGT), the first zero-carbon building in Taiwan. This study simulated the energy performance of the MSGT by using eQUEST, a tool for simulating building energy, before the construction was complete. This study compared the simulated energy use with the actual energy use of the MSGT in 2011, and determined that the actual energy use was lower than the simulated energy use. Based on this comparison, the study proved that the MSGT consumed 65% less energy than do similarly sized buildings with the same functions.

AbstractThis research focuses on the energy performance of office building in Wuhan. The research explored and predicted the optimal solution of design variables by Multi-Island Genetic Algorithm (MIGA) and RBF Artificial neural networks (RBF-ANNs). Research analyzed the cluster centers of design variable by K-means cluster method. In the study, the RBF-ANNs model was established by 1,000 simulation cases. The RMSE (root mean square error) of the RBF-ANNs model in different energy aspects does not exceed 15%. Comparing to the reference case (the largest energy consumption case in the optimization), the 214 elite cases in RBF-ANNs model save at least 37.5% energy. By the cluster centers of the design variables in the elite cases, the study summarized the benchmark of 14 design variables and also suggested a building energy guidance for Wuhan office building design.

A common envelope performance problem in buildings is thermal bridging through balcony slab connections, which can be improved with the use of commercially available thermal break products. Several prior studies have used simulation-based and/or hot box test apparatus approaches to quantify the likely effect of balcony thermal breaks on effective thermal resistance of building enclosures. However, in-situ measurements of thermal performance in real buildings remain limited to date. This study uses a combination of field measurements and models to investigate the effects of installing balcony thermal breaks on the interior surface temperatures, effective thermal resistance, and annual building energy consumption. For the field experiment, yearlong measurements were conducted on the 13th floor of a 14-story multi-family building in Chicago, IL, in which thermocouple sensors were embedded into eight balconies and their adjacent interior floor slabs just before concrete was poured to complete the construction. The eight balconies included four control balconies without thermal breaks and four thermally-broken balconies with a commercially available thermal break product installed. The experimental data were then combined with 2-D heat transfer modeling and whole building energy simulations to investigate the impacts of the thermal break product installation on the envelope thermal resistance and overall energy use in the case study building as well as in several more generic building designs with simpler geometries. The results demonstrate that although the balcony thermal breaks helped regulate interior slab temperatures and improved the effective thermal resistance of the curtain wall enclosure assembly by an estimated ~14% in the case study building, the predicted effect on annual energy consumption in all modeled building types was small (i.e., less than 2%). The results also highlight the importance of paying careful attention to envelope design details when using thermal break products and considering the use of thermal break products in combination with other energy efficiency strategies to achieve high performance enclosures.

In this study, the authors explore the impact of the enhanced commissioning process required by LEED certification on the Architecture, Engineering and Construction (AEC) professionals through a case study of a (LEED) New Construction in New Cairo, Egypt. While research has consistently shown the positive impact of green-rated buildings on building occupants, little research discusses the impact of green building rating on AEC professionals. Observation, document analysis, and interview of AEC professionals were used throughout the course of design and construction to identify the impact of the enhanced commissioning process on the quality of Project delivery and experience of AEC professionals. All technical and managerial issues of the entire enhanced commissioning process were recorded and thoroughly analyzed. As a result, a comprehensive comparison between mainstream projects and the current LEED-certified building is established. The study introduces a novel insight on green building design and construction practice as a potential culture of quality for the building industry in developing countries.

Cities and nations worldwide are pledging to energy and carbon neutral objectives that imply a huge contribution from buildings. High-performance targets, either zero energy or zero carbon, are typically difficult to be reached by single buildings, but groups of properly-managed buildings might reach these ambitious goals. For this purpose we need tools and experiences to model, monitor, manage and optimize buildings and their neighborhood-level systems. The paper describes the activities pursued for the deployment of an advanced energy management system for a multi-carrier energy grid of an existing neighborhood in the area of Milan. The activities included: (i) development of a detailed monitoring plan, (ii) deployment of the monitoring plan, (iii) development of a virtual model of the neighborhood and simulation of the energy performance. Comparisons against early-stage energy monitoring data proved promising and the generation system showed high efficiency (EER equal to 5.84), to be further exploited.

Heating And Cooling

The concern regarding local responsive building design has gained more attention globally as of late. This is due to the issue of the rapid increase in energy consumption in buildings for the purpose of heating and cooling. This has become a crucial issue in educational buildings and especially in schools. The major issue in school buildings in Saudi Arabia is that they are a form of prototype school building design (PSBD). As a result, if there is any concern in the design stage and in relation to the selection of building materials, this will spread throughout the region. In addition to that, the design is repeated regardless of the climate variation within the kingdom of Saudi Arabia. This research will focus on the influence of the window to wall ratio on the energy load in various orientations and different climatic regions. The research will use the energy computer tool TAS Environmental Design Solution Limited (EDSL) to calculate the energy load as well as solar gain. During the visit to the sample schools, a globe thermometer will be used to monitor the globe temperature in the classrooms. This research introduces a framework to assist architects and engineers in selecting the proper window to wall ratio (WWR) in each direction within the same building based on adequate natural light with a minimum reliance on energy load. For ultimate WWR for energy performance and daylight, the WWR should range from 20% to 30%, depending on orientation, in order to provide the optimal daylight factor combined with building energy efficiency. This ratio can be slightly greater in higher altitude locations.

Point Of Interest

Urban building energy modeling (UBEM) is arousing interest in building energy modeling, which requires a large building dataset as an input. Building use is a critical parameter to infer archetype buildings for UBEM. This paper presented a case study to determine building use for city-scale buildings by integrating the Geographic Information System (GIS) based point-of-interest (POI) and community boundary datasets. A total of 68,966 building footprints, 281,767 POI data, and 3367 community boundaries were collected for Changsha, China. The primary building use was determined when a building was inside a community boundary (i.e., hospital or residential boundary) or the building contained POI data with main attributes (i.e., hotel or office building). Clustering analysis was used to divide buildings into sub-types for better energy performance evaluation. The method successfully identified building uses for 47,428 buildings among 68,966 building footprints, including 34,401 residential buildings, 1039 office buildings, 141 shopping malls, and 932 hotels. A validation process was carried out for 7895 buildings in the downtown area, which showed an overall accuracy rate of 86%. A UBEM case study for 243 office buildings in the downtown area was developed with the information identified from the POI and community boundary datasets. The proposed building use determination method can be easily applied to other cities. We will integrate the historical aerial imagery to determine the year of construction for a large scale of buildings in the future.
