This paper analyzes Leadership in Energy and Environmental Design for Interior Design and Construction: Commercial Interior (LEED-CIv4) projects, thereby presenting the first empirical evidence of these projects. The aim of the study was to reveal trends in Certified, Silver, Gold, and Platinum LEED-CIv4 US projects, certified in 2014–2019. The effect size between possible and achieved points in categories and credits was measured using Cliff’s δ. The following conclusions were drawn: (i) the Integrative Process, Innovation, and Regional Priority categories showed high achievements only in Platinum projects, so it is necessary to reconsider these categories toward increasing their acceptance at all certification levels; (ii) the Location and Transportation and Indoor Environmental Quality categories were quite well-designed because most credits in these categories showed varying levels of achievement (low/medium/high/very high) at all four certification levels; and (iii) the Water Efficiency, Energy and Atmosphere, and Material and Resources categories were badly designed because most credits there similarly showed low achievements at all four certification levels, thus needing more attention toward their improvement in the next LEED-CI version.

To date, no empirical evidence has been published on the certification achievements of Leadership in Energy and Environmental Design for New Construction (LEED-NCv4) projects. Therefore, the aim of this study was to determine the trends in LEED-NCv4 Certified, Silver, Gold, and Platinum projects in the U.S. Boxplots were used to measure the consistency of achievement points in categories; Cliff’s δ was used to measure the effect size between possible points and achieved points in categories and credits. The findings show that (1) the categories Sustainable Sites and Energy and Atmosphere were well designed, with consistency increasing from level to level and almost all their credits achieving low–very high points; (2) the categories Water Efficiency and Indoor Environmental Quality showed an average design, and certification levels were found to be inconsistent across the projects and only approximately half of the credits achieved medium or high points, whereas the other half achieved low points; and (3) the categories Location and Transportation and Materials and Resources were the worst designed, with four certification levels found to be inconsistent across the projects and most of the credits achieved low points.

The Difference

The Leadership in Energy and Environmental Design (LEED) is currently intensively applied in several European countries. The aims of the present study were to compare the difference between (i) two countries from the same region (i.e., Finland vs. Sweden or Turkey vs. Spain) and (ii) two European regions (northern Europe [Finland and Sweden] vs. [Turkey and Spain]) when the LEED- New Construction (NC) 2009 Certified rating level certified projects were analyzed. We found that, in the northern and southern parts of Europe, LEED- NC 2009 credit achievements in terms of Sustainable Sites (SS), Water Efficiency (WE), Materials and Resources (MR), and Indoor Environmental Quality (EQ) were similar, whereas credit achievements in Energy and Atmosphere (EA) were different. High achievements were revealed in WE and SS, with values of 80–100% and 70–75%, respectively; intermediate achievements were revealed in EQ, with values of 40–60%; and low achievements were revealed in MR (20–40%). EA achievements were intermediate (60–65%) in northern Europe, while they were low in southern Europe (40%). This evidence can help recognize the categories that are performed with a high number of points and those that are performed with a low number of points.

Layer Concept

Leadership in Energy and Environmental Design Commercial Interiors (LEED-CI) is more relevant to interior design, which, according to the sharing layer concept, differs from exterior design (which is usually evaluated with the LEED New Construction sub-scheme). LEED-CI requires separate empirical analyses of LEED-CI certified buildings to further improve this sub-scheme. Therefore, in this study, Silver and Gold projects certified under LEED-CI-2009 in 14 US states were considered. Three project performance analyses, (i) certification, (ii) category, and (iii) cross-certification, were studied. The following results were revealed: (i) the range of the medians for Silver- and Gold-certified projects were 51–57 pts and 62–71 pts, respectively; (ii) in both Silver- and Gold-certified projects, Sustainable Sites (SS), Water Efficiency (WE), and Innovation in Design (ID) were the best-performing; Energy and Atmosphere (EA) and Indoor Environmental Quality (EQ) were intermediate-performing; and Material and Resources (MR) was the worst-performing categories; and (iii) in Silver-Gold cross-certification, category-focused (in 10 of 14 states) and category-unfocused (in four of 14 states) strategies were determined; in the category-focused strategy, the highest popular category was EA; the intermediate popular categories were WE, MR, and ID; and the lowest popular category was SS. Pooling all projects and all states into one frame can lead to the obscurement of the actual LEED-CI-2009 strategy(ies) in the transition from Silver to Gold certification in the US.

The Mediterranean Basin

Leadership in Energy and Environmental Design (LEED) has five basic categories: Sustainable sites (SS), Water Efficiency (WE), Energy and Atmosphere (EA), Materials and Resources (MR), and Indoor Environmental Quality (EQ). Additionally, in LEED 2009, the U.S. Green Building Council (USGBC) introduced regional priority (RP) points to adapt LEED to the local conditions of foreign countries. However, the appropriateness of the RP points stated for the Mediterranean basin has not yet been evaluated. Thus, we studied the similarities and differences in performances of LEED 2009 Commercial Interiors (CI) and LEED 2009 Core and Shell Development (C&S) Gold certified projects in Turkey, Spain, and Italy. We revealed that the categories without RP points, SS, MR, and EQ, performed similarly in all three countries, thereby signaling the correctness of CI and C&S applications in the Mediterranean basin. However, the categories with RP points, WE and EA, performed differently. It can be suggested that the following RP points would be beneficial for all three countries: (i) in the MR category, RP points that initiate decreases in virgin construction material; (ii) in the WE category, RP points that encourage water saving; and (iii) in the EA category, RP points that encourage using renewable energies.

Indoor environmental quality is a requirement for good architectural and interior design. The definition of indoor environmental quality refers to the conditions of the interior space that provide health and wellbeing for its occupants. Elements of indoor environmental quality are thermal comfort, indoor air quality, ventilation, ergonomics, natural and artificial lighting, odor, and acoustic quality. Indoor environmental quality is required in every type of interior space including ones with residential, educational, and cultural functions and workspaces. It is also included as one of the factors of energy efficient and sustainable design in building energy certification and accreditation systems. This study focuses on call center interiors as a type of workspaces, where the employees spend a long time in the interior space communicating with customers on the phone. The aim is to provide theoretical information and practical application suggestions for higher quality design in call center interiors. The methodology of this paper consists firstly of a literature review to study and analyze the definition and elements of indoor environmental quality, and its implementation into call center interiors as workspaces. Analytical studies lead to strategy proposals for better designed call center interior spaces. The results of the study indicate that better designed interior spaces in call centers lead to better health and wellbeing of the employees, resulting with higher performance and service quality.

Environmental Quality Assessment

Michigan State University and the Michigan Department of Natural Resources established a partnership for sustainable park planning in October 2011. The purpose of the partnership was to enable students in the design fields to work on real-world projects and provide practical solutions. One of the notable projects was to assess old historic buildings in one state park and propose renovation plan to improve its indoor environmental quality and energy efficiency. The buildings in the park functioned as the traveler’s destination in the 1920s and still preserve original interior and exterior features. The team of undergraduates and faculty in interior design visited the park and assessed the interior and exterior conditions of two of its buildings. They used an assessment tool which was designed on a basis of the elements in the indoor environmental quality category (IEQ) of the US Green Building Council’s LEED. Results revealed that the indoor environmental conditions of the buildings should be improved. The energy efficiency of the buildings was low. Based on this assessment, this study offered practical suggestions for improving the building’s indoor environmental quality. This study also proposed an assessment tool for the historic buildings in the state parks in Michigan to assess current indoor environmental quality of those buildings.

ABSTRACT The applicability of building rating systems has gained attention for achieving indoor environmental quality. Considering the wider internationalized recognition of LEED (Leadership in Energy and Environmental Design) and other rating systems, the case of Jordan provides a sense of particularity in consideration to its rather recent history in acknowledging these progressive standards. Utilizing a mixed approach based on paired comparisons between local LEED and non-LEED certified buildings, this research paper explores the level of satisfaction pertaining to Indoor Environmental Quality of building occupants. While it touches on the generality of such satisfaction, it proceeds to unpack and investigate how it resonates with the sustainability of the building measured through various means. The research outcomes reflected an overall appeal of LEED certified buildings and a decent level of comfort of their dwellers. Yet, it conveyed a vague, rather sporadic relation when comparing the subjective perception to the objective measures due to multiple potential reasons. The paper concludes by stressing the need for further appropriation of international environmental codes to better suit the local context. It lays a reliable foundation for further research, utilizing more case studies and exploring the applicability of rating systems in Jordan.

Plastic waste affects environmental quality and ecosystem health. In 2010, an estimated 5 to 13 million metric tons (Mt) of plastic waste entered the ocean from both developing countries with insufficient solid waste infrastructure and high-income countries with very high waste generation. We demonstrate that, in 2016, the United States generated the largest amount of plastic waste of any country in the world (42.0 Mt). Between 0.14 and 0.41 Mt of this waste was illegally dumped in the United States, and 0.15 to 0.99 Mt was inadequately managed in countries that imported materials collected in the United States for recycling. Accounting for these contributions, the amount of plastic waste generated in the United States estimated to enter the coastal environment in 2016 was up to five times larger than that estimated for 2010, rendering the United States’ contribution among the highest in the world.
