This study examines the non-USA industry practitioner’s perspective on building information modeling maturity (BIMM). The purpose of this study is to get a more comprehensive understanding of the practitioner’s perspective on critical indicators of building information modeling (BIM), to better help academicians and the industry understand the current global status of BIM adoption. The findings of this study will better equip educators and industry practitioners in identifying BIM indicators that are important and therefore, help improve the future adoption and implementation of BIM in the Global context. Indicators in this study are grouped under four maturity factors: technology, information, process, and people. The methodology used was a survey deployed to industry practitioners with the purpose of conducting a quantitative study on the data collected by analyzing the mean and standard deviations to provide a ranking of the BIM indicators. The findings of the study revealed that indicators associated with the Information maturity factor, were of the greatest significance to non-USA practitioners.

Net Zero Energy Buildings (NZEB) are being constructed throughout the United States, promoting construction practices that achieve more than the minimum energy performance required to meet current codes and demonstrating their financial feasibility. The practicality of these technologies have been proven, in many cases, to improve energy efficiencies, and to provide buildings with capabilities to produce the energy levels necessary to sustain the building operation systems while maintaining comfort and minimizing the financial payback period of the investment. Broadly, these strategies include changes in site selection, water efficiencies, reducing energy consumption, and utilizing environmentally benign materials. This paper presents a detailed review of existing and developing technologies and their effectiveness in replacing conventional design and building strategies at all levels of the design and construction process. In addition, this work provides a user-friendly road map to assist practitioners in planning and implementing the energy reduction strategies necessary to move toward achieving energy efficiency, improving the indoor air quality and constructing buildings zero energy ready. Strategies for implementing energy efficiency measures in low-cost, budget-restrained conditions are also described.

This study investigates the prioritization of key BIM Maturity (BIMM) indicators by stakeholders with experience in BIM-assisted projects. A literature review was conducted to identify an initial pool of BIMM indicators, based on which a survey was generated and administered to global BIM-related practitioners. Descriptive statistics and ranking comparison are used to study the perceived importance of each BIMM indicator for practitioners with different business types and experiences. The results show that although there is a general agreement in the key BIMM indicators and the key dimensions among stakeholders with different profiles, there are significant differences in the perceived importance and ranking of some specific indicators and dimensions. This research has both theoretical and practical contributions. Theoretically, this study offers empirical evidence and possible justification about the underlying differences and agreement among global practitioners with different profiles.
Practically, current BIM practitioners can improve their BIM implementation by focusing on the key areas of BIMM and by better understanding the perceived difference of different stakeholders. Meanwhile, potential adopters of BIM can understand what BIM implementation really entails and the perceived focus of BIMM by practitioners with different years of experience.
With increasingly stringent energy standards set in place by the Department of Energy, energy efficiency is
becoming a paramount concern to manufacturers of appliances. Additionally, the production and disposal of the voluminous amount of polyurethane foam commonly utilized as insulation in refrigeration units poses a significant environmental challenge. In this context, this study investigated an alternative insulation for use in commercial refrigerator/freezer units. A prototype exploring the use of evacuated packets of pyrogenic silica substituting for conventional insulation was assessed. Assessment criteria included experimental comparison of heat transfer characteristics and the energy efficiency of the new insulation as well as its life cycle as it is related to environmental sustainability. Results indicate that in the new insulation design applied to the unit’s cover, heat flux decreased by an average of 36%, and energy efficiency improved by 5.1% over a 24 hour period. The new insulation design also resulted in improved environmental sustainability, resulting in a savings of 0.257 metric tons of CO2e over 20 years for a single unit. Results provide an alternative insulation design for use in commercial refrigerator and freezers, and a framework by which to assess the efficiency and environmental performance of similar products.
