The building industry is associated with several environmental impacts. In considering the total building lifecycle, the use phase has a strong influence on the level of impact. According to the literature, the use phase of residential buildings represents up to 92% of energy consumption, constitutes 95% of water consumption (indoor and outdoor), accounts for 45% of the weight of materials used, and produces 50% of the waste (maintenance, repair, and renovation). Green building and certification programs used in North America, such as BOMA-BESt®, LEED®, and Living Building ChallengeTM, aim to reduce the environmental footprint of housing. However, while these certifications provide a useful framework for practices related to buildings and their systems, a documentary analysis shows that they do not adequately take into account the use phase of residential buildings. The purpose of this paper is to show that consideration of the use phase is inconsistent with the impacts associated with it.

Urbanization and technology have proven to be detrimental to the environment. Buildings contribute a significant portion of this damage. This issue motivated governments, builders, engineers, and architects to seek ways to reduce buildings’ environmental footprints. Leadership in Energy and Environmental Design (LEED), developed by the U.S. Green Building Council (USGBC), is one of the most widely used strategies to ensure energy efficiency and a clean environment in buildings. In Afghanistan, where there are no active regulatory frameworks for energy saving and efficiency for the building sector, it is imperative to promote the transformation of the building industry and practices towards sustainability. In this regard, the role of the residential building sector is of utmost importance due to its major share in the country’s energy consumption and GHG emissions profile. Thus, this study assesses the energy efficiency and environmental impact of existing buildings in Kabul city concerning the LEED rating system. This research suggests practical steps to improve the sustainability of the residential building stock in Kabul city. Robust sets of data on existing residential buildings in Kabul are collected, classified, evaluated, and compared to LEED standards. This research reveals and concludes that most of the existing buildings in Kabul city are in poor conditions and do not meet the minimum requirements to be a candidate for LEED certification. A detailed analysis of the results has led to recommendations on how these buildings could improve to meet the LEED criteria. This is the first study of its kind conducted for Kabul city residential building. Considering the cross-sectoral nature of the building industry, the findings of this study will contribute to many other areas such as water, transportation, ICT, health, energy and the environment.

Green Certification

The Living Community Challenge (LCC) is a green certification program that, unlike most certification programs, is geared toward whole neighborhoods as opposed to singular buildings. Unfortunately, no existing communities have achieved Living Community Challenge certification. Still, there are many neighborhoods utilizing the ideals – known as petals – of the LCC in attempts to become more sustainable. The Living Building Challenge (LBC), the parent certification for the LCC, has seen more success than the LCC and will provide further research on the implications of its criterion. This paper will look at the hypothetical variables of the LCC, the communities trying to achieve these variables, and how elements of it could be used in relation to impoverished communities. Through case studies on groups and individuals attempting LCC and LBC certification, specifically Bend, Oregon and the BLOCK Project, the potential of the research becomes evident. This paper seeks to demonstrate how the LCC could be applied specifically in low-income areas in Gainesville, FL without achieving all the requirements of each petal.

The degree of technical wear of old buildings, which are made of basic materials (cement, concrete, steel, timber, plaster, brick) using traditional technology, is expressed by the size and intensity of damage to their elements. The topic of the research concerns old residential buildings from the turn of the 19th and 20th centuries, which are located in the downtown district of Wroclaw, Poland. The descriptive analysis and the analysis of the definitions of defects that occur in the elements of residential buildings, which were performed as random analyzes, do not allow defects to be considered as measurable variables at a level of visual investigation. The major drawback of the method that is used by experts when assessing the technical condition of civil engineering buildings is that it does not numerically express the magnitude (strength) of the defects. Therefore, an attempt was made to numerically express the relationship (if such a relationship exists) between the occurred defects of buildings and the extent of their technical wear process. When calculating the strength of this relationship, the method of determining the point biserial correlation coefficient for the measurable property and the dichotomous property was used. It was found that the direction of the relation is right-hand for all the tested building elements, but the strength of the correlation between the detected defects and technical wear shows a considerable span and depends on the conditions of the apartment house’s maintenance. As a rule, damage caused by water penetration and moisture penetration always shows correlations of at least moderate strength.

One of the consequences of COVID-19 pandemic is the momentum it has created for global changes affecting various aspects of daily lives. Among these, green building certification systems (GBCSs) should not be left behind as significant potential modifications may be required to ensure their versatility for residential buildings due to the new pandemic reality. The present study aims to evaluate the readiness of chosen GBCSs for a proper assessment of existing residential housing sustainability in a post-pandemic world. Based on a literature review of the state-of-the-art data sources and round table discussions, the present study proposes a particular set of sustainability indicators covering special sustainability requirements under pandemic conditions. Then, those indicators are used to evaluate the readiness of selected GBCSs (BREEAM, LEED, WELL, CASBEE) to meet new pandemic-resilient requirements based on their responses to the indicators. The assessment shows that none of the reviewed GBCSs are fully ready to cover all the proposed indicators. GBCSs have differing focuses on particular sustainability pillars, which also affected their responses to pandemic-resilient categories. For instance, WELL rating system successfully responded to the health and safety category, whereas LEED showed better preparedness in terms of environmental efficiency. BREEAM and CASBEE systems have a more evenly distributed attention to all three pandemic-resilient categories (Health & Safety, Environmental Resources Consumption, and Comfort) with an accent on the Comfort category. On a specific note, all GBCSs are insufficiently prepared for waste and wastewater management. In the future, GBCSs should be modified to better adapt to pandemic conditions, for which the current work may provide a basis. As an alternative, brand new standards can be created to face newly arising and evolving post-pandemic requirements.

The natural ventilation of residential areas has placed more and more emphasis on residential area planning, according to the relationship between natural ventilation environments and the layout of architecture, we can reduce the energy consumption and the adverse effect of wind outdoors, improve the living environment and quality of life, making harmony between human and the nature. In this paper, we use Air-Pak to simulate the wind environment of residential areas. Through analyzing and simulating the air field which forms when the wind blows around the residential buildings by Air-Pak, we explain the advantage of the combination of computer simulation software and residential area planning. And we give some advice to the layout of the outdoor environment early in the residential planning area by the simulation of outdoor environments of buildings.

Leed Buildings

The US Green Building Council's (USGBC) Leadership in Energy and Environmental Design (LEED) green building rating program has grown from a little known tool for market change to a label and brand relied upon by many of the largest players in real estate. It now serves as an indicator of sustainability and an instrument for environmental management. While LEED-certified buildings tend to offer greater environmental benefits than their conventional counterparts, research and experience shows that the variation in and magnitude of these benefits varies, even among buildings of the same LEED certification level. In light of growing concerns about “greenwashing” and the liability associated with questionable environmental declarations, it is important to ensure that users of LEED and similar certification programs receive a set of benefits comparable to those expected. With a focus on energy-related issues, this research (1) highlights evidence of the inconsistency between the expected and actual benefits of LEED buildings, (2) suggests revisions to LEED's Energy & Atmosphere (EA) section to reduce the variation and magnitude in the energy-related environmental impacts from LEED buildings, (3) quantifies this reduction in variation and magnitude of impacts using Monte Carlo analyses and probabilistic models created specifically for this research, (4) compares carbon dioxide emissions from LEED buildings to the Architecture 2030 Challenge goals and (5) quantifies the importance of scoring LEED buildings on a per capita normalized basis. This research is a follow-up piece to the authors' previous work published in the Journal of Green Building (Wedding and Crawford-Brown 2007).
