Green guarantees Vex Firms with added risk

February 2013

Authors:

More government owners of green projects are demanding long-term performance guarantees, and contractors and designers are trying to figure out how to defray the risks of such commitments. Required guarantees can range from getting a specified LEED certification to promising a building will deliver a specific amount of energy savings after occupancy. Owners' insistence that architects, engineers, construction companies and other contractors guarantee their work on sustainable projects coincides with the rise in demand for LEED-certified and other sustainable buildings. Owners pay a premium for green buildings, and they want to make sure they get their money's worth. Requiring new buildings to be sustainable has even become part of some city and state building codes, so contractors must deliver those buildings by law. Some insurers suggest contractors get all parties participating in any guarantee involved in the process as early as possible and perhaps bring in a third-party facilitator as well. That strategy ensures that parties understand and agree to the same objectives.

Integration Models of Building Information Modelling and Green Building Rating Systems: A Review

June 2018 · Journal of Computational and Theoretical Nanoscience

The extensive impact of construction on the environment and the increasing demand for greener buildings have pushed forward the building industry to adopt new approaches for sustainable building design. In the light of this issue, many countries developed their own green rating system for building sustainability assessment and rating. However, the process of executing this task to benchmark ... [Show full abstract] building sustainability is based on fragmented and manual methods which is time-consuming, laborious and inefficient. Simultaneously, many research and real case studies have argued that the implementation of Building Information Modelling (BIM) in green building design process is advantageous throughout the building life cycle. One of the critical research topics in such implementation is the integration of BIM with green rating systems in order to assess building sustainability and facilitate green certification documents provision. Hence, the purpose of this paper is to review available BIM-based methodologies and proposed models made for green building assessment and certification, which have been developed to be integrated with several rating systems around the world such as LEED® and BREEAM®. The results show that the integration of BIM with green building rating system is applicable. Nevertheless, still more focus on specific rating systems, mainly LEED®. Thus, further research and development are required in this area to integrate other recent rating systems and enhance the level of automation by integrating green material databases and new BIM technologies such as visual programing and cloud-based databases.

February 2018 · Renewable and Sustainable Energy Reviews

Building performances play a fundamental role in the worldwide energy scenario. In the last years, many countries have developed certification procedures in order to rate the environmental sustainability of buildings, aiming at reducing energy consumptions and environmental impacts during the construction, management and operational phases of a building. This study firstly provides an overview of ... [Show full abstract] the different certification procedures employed in several countries all over the world, considering also which Green Building Rating System (GBRS) is only applied in its own country and which one is developed in other countries by means of proper adaptations. Five widespread and well known green building rating systems (CASBEE, Green Star, BREEAM, LEED and ITACA) are then analyzed in detail and differences and similarities among them are highlighted. To this aim, six new macro-areas (site, water, energy, comfort and safety, materials and outdoor quality) are defined and a normalization procedure is implemented, in order to provide significant information about the sustainability aspects taken into account in the different rating tools and aiming at comparing them. This comparison allows to identify the main features of the five tools and to highlight qualitative and quantitative differences. The analysis shows that the certification tools are not homogeneous from both points of view. The aim of this work is to understand which issues have more influence on the final performance rate of each system and to give to final users a deeper knowledge of the aspects included in these tools.

May 2014 · Journal of Management in Engineering

Design-build (DB) is regarded as an effective means of delivering high performance green buildings, and the selection of DB contractors is of critical importance. The objective of this study is to evaluate the selection of design-builders for public buildings seeking leadership in energy and environmental design (LEED) certification and compare the selection practices involved with those of ... [Show full abstract] non-LEED-seeking DB projects through a robust content analysis of 74 DB requests for proposals (RFPs) for public DB projects. The results of the content analysis reveal that the level of LEED certification is the dominant means of conveying the sustainability requirements in RFPs for contractor selection, with the majority of RFPs (60%) including sustainability requirements as part of the contractor evaluation package. With the exception of contractors’ past performance, there is no statistically significant difference in the importance weights of selection criteria between LEED-seeking and non-LEED-seeking buildings, and DB owners tend to place more emphasis on innovative technical solutions rather than the past performance of DB contractors. Additionally, the research findings also indicate that owners of LEED-seeking building projects tend to provide fewer design decisions in RFPs to solicit innovative design alternatives from potential DB contractors. This study provides DB owners with a number of practical implications for selecting appropriate design-builders for green DB projects.

Analysis of Green Building Certification System for Developing G-SEED

February 2018 · Future Cities and Environment

G-SEED (Green Standard for Energy and Environmental Design) is operating in Korea as a certification system to evaluate the environmental friendliness of buildings. Buildings are generating loads such as carbon dioxide emission, energy consumption, the consumption of resources, destruction of natural ecosystem, change of global climate, pollution of indoor environment, and waste generation. For ... [Show full abstract] this purpose, a green building certification system has been introduced. In the green building certification system, evaluation of buildings through methods such as utilization of natural energy, adoption of energy saving system, rainwater management, etc., is induced to reduce environmental load. These certification systems are operated by each country. The level of the certification system is different according to the characteristics such as climate environment. BREEAM in the UK and LEED in the US are operating a version for international certification as well as domestic certification. In this study, analyze the certification system which operates the global version such as BREEAM, LEED. And to investigate the differences between domestic and international versions of each version of the certification system. Certification items classified as reflected by climate characteristics, national characteristics reflected items, general items, such as attempts to analyze the rating system. And certification items were grouped into general “Global certification items” having no specificity for locality and “Local certification items” that differ by each locality according to social, environmental, and political factors. Using the analysis results that comparison of LEED and BREEAM, the study then aims to ascertain the possibility of whether the G-SEED can be used to certify international buildings. And explore the possibility of developing international version of the G-SEED and indicate the direction of G-SEED amendments that may arise in the future. The study results would be available as basic data at the development of G-SEED for international version.

Integrating BIM with Green Building Certification System, Energy Analysis, and Cost Estimating Tools...

May 2014 · Electronic Journal of Information Technology in Construction

It is commonly known that the energy consumption of buildings is quite high; therefore, owners, architects, and engineers should be more concerned about the sustainability and energy performance of proposed building projects. For years, energy analysis tools have been used by designers to design energyefficient buildings. Generally, the energy analysis for this type of facilities is mostly ... [Show full abstract] conducted at the end of the design stage, once their components and elements have already been selected. However, analyzing the energy consumption of those components at the conceptual design stage is very helpful for designers when making decisions related to the selection of the most suitable design alternative that will lead to an energy-efficient building. Building Information Modeling (BIM) has the capability to help users assess different design alternatives and select vital energy strategies and systems at the conceptual design stage of proposed projects. Furthermore, by using BIM tools, designers are able to select the right type of materials early during the design stage and to make energy-related decisions that have great impact on the whole building life cycle. The main objective of this paper is to propose an integrated methodology that links BIM and energy analysis tools with green building certification systems. This methodology will be applied at the early design stage of a project's life. It will help designers measure and identify potential loss or gain of energy for different design alternatives and calculate the potential LEED points they may accumulate and gain and accordingly select the best one. An actual building project will be used to illustrate the workability and capability of the proposed methodology.
