A review on critical success factors of sustainable retrofitting implementation

Sustainable retrofitting has been one of the alternate solutions to mitigate greenhouse gas emissions and climate change. However, it is apparent that limited existing buildings are being sustainably retrofitted and the reason lies within the influential forces which contribute to the failure of the sustainable retrofitting project. Thus, this study aims investigates the current literature based on critical success factors (CSFs) for sustainable retrofitting and to identify any gap that might exists. Journals were searched using the key words identified from the preliminary literature review. Successive round of article abstract reviews resulted in 59 articles being selected for compilation purpose. The CSF constructs were then identified using content analysis and inductive coding approach. Critical analysis of the literature revealed gaps in the literature. The most significant findings was the lack of research on CSFs for sustainable retrofitting from the stakeholders’ perspective. This research provides a comprehensive compilation of all previously identified CSFs for project purpose

A structured critical success factors model for the implementation of green retrofit projects

Existing buildings contribute to half of all annual energy and greenhouse gas emissions. Green retrofit has been the latest value added service under the facility management field to mitigate climate change caused by greenhouse gas emission. Yet, green retrofit implementation is not widely practiced by existing building stakeholders due to lack of participation and cooperation among them. Among the issues of green retrofit are high upfront costs and uncertain return, lack of green building professionals, lack of financial incentives, knowledge gap in green development quantification, lack of green awareness, lack of communication among the stakeholders, lack of internal leadership and lack of green materials and technology. These factors contribute to the failure of green retrofit projects’ implementation. Thus, the aim of this research is to identify the critical success factors (CSFs) of green retrofit projects’ implementation. The specific objectives of this research are: to identify the CSFs of green retrofit; to evaluate the criticality and ranking of CSFs of green retrofit; and to develop structural model for the CSFs of green retrofit. The research methodology adopted to achieve the aim of this research is quantitative method using a survey based approach consisting of three steps namely literature review, experts’ opinions and questionnaire survey. Based on literature review, eight CSFs with thirty three indicators of green retrofit implementation were identified. Experts’ opinions were sought to validate the identified CSFs and to develop relationships among the CSFs using an Interpretive Structural Modelling (ISM). Questionnaire survey was conducted to empirically confirm the ISM-Based Model using Structural Equation Modelling (SEM). The final model consists of eight CSFs with twenty seven indicators with CSF 1 (green building professionals) and CSF 5 (internal leadership) being the major drivers for the success of the green retrofit projects implementation

Benchmarking Index 2019: Carbon, Energy, and Water

The sixth annual Cornell Hotel Sustainability Benchmarking study finds that participating hotels generally have continued to reduce their energy and water use, although the energy intensity recorded by luxury hotels continues to be relatively high. With information from over 11,000 hotels, the study includes data from substantially more hotels than in all previous years. While the bulk of the data come from hotels in the United States, the study also recorded a greater international participation, with forty-eight nations and seventeen international brands represented. Participating hotels contributed information regarding their energy and water use, as well as greenhouse gas emissions, with data complete as of 2017. While these data permit hoteliers and potential guests to see benchmarks for various hotel segments and locations, individual hotel amenities cannot be accounted for in terms of energy or water use. This year’s study further analyzed the range among data sets to identify the common “efficiency gap range” between the upper and lower quartile among similar hotels, presenting the opportunity and business case for designing and operating energy- and water-efficient hotels. Data collection is now underway for CHSB2020 study, and the authors encourage additional hotels to participate, especially those in the lower tier segments, which are not as strongly represented in these data.ricaurte_2019_index_to_post.pdf: 1164 downloads, before Aug. 1, 2020.0-CHSB2019_Index_Tool_081319.xlsx: 649 downloads, before Aug. 1, 2020

Hotel Sustainability Benchmarking Index 2020: Carbon, Energy, and Water

The seventh annual Cornell Hotel Sustainability Benchmarking study includes data from considerably more hotels than last year. While the bulk of the data still come from hotels in the United States, the study also recorded a greater international participation, with 55 nations and 20 international hotel chains represented. More than 18,000 hotels contributed information regarding their energy and water usage, as well as their greenhouse gas emissions. Complete as of 2018, the data show that the participating hotels have generally continued to reduce their energy and water usage. While the data permit hoteliers and potential guests to see benchmarks for various hotel segments and locations, individual hotel amenities cannot be accounted for in terms of energy or water usage. Data collection is now underway for CHSB2021 study, and the authors encourage additional hotels to participate, especially those in the lower-tier segments which are not as strongly represented here

Hotel Sustainability Benchmarking Index 2023

For the ninth consecutive year, the annual Cornell Hotel Sustainability Benchmarking research reveals a general decrease in energy and water usage among the participating hotels. The decrease is largely associated with the pandemic which shook the world and granted no exception to the hospitality industry. For this reason, low occupancy rates and hotel closures are major contributors to the decreased energy and water consumption reported, as compared to the 2019 calendar year data set. A total of 25,576 hotels from 31 international hotel groups took part by providing data on their water and energy use for the calendar year of 2021. Of the total, around 50 percent of the data set comes from hotels in the United States. The data do not account for individual hotel amenities in terms of energy or water usage, but they do allow hoteliers and potential visitors to see benchmarks for different hotel segments and locations. Despite the challenges faced by the industry, the study continues to present a strong picture of the industry’s performance over the years. To provide a more robust and useful data set of the industry for benchmarking and to promote improvements in energy, water, and carbon performance, the authors encourage additional hotels and hotel chains to take part in CHSB2024, especially those in the lower tier segments, which are not as strongly represented

Hotel Sustainability Benchmarking Index 2021: Carbon, Energy, and Water

The annual Cornell Hotel Sustainability Benchmarking study, published for the eighth consecutive year, finds a general reduction in energy and water usage among the participating hotels over the past three years (2017 -2019). However, a slight increase in usage is reported among full-service resorts, a new grouping established for this year’s reporting. A total of 21,432 hotels from 26 international hotel chains participated by contributing information regarding their energy and water usage. Over 60% of the total data comes from hotels in the United States. While the data permit hoteliers and potential guests to see benchmarks for various hotel segments and locations, individual hotel amenities are not accounted for in terms of energy or water usage. The authors encourage additional hotels and hotel companies to participate in the study, as increased participation allows us to build a stronger and more meaningful data set of the industry for benchmarking and to drive improvements in energy, water, and carbon performance

Hotel Sustainability Benchmarking Index 2024

For the first time in the ten annual cycles of the Cornell Hotel Sustainability Benchmarking cycle, we find a general increase from 2021 to 2022 in energy and water consumption among participating hotels. This increase is largely associated with the global recovery from the anomaly of 2021, where occupancy levels were lower than usual and most hotels were not operational for the full year due to the pandemic. The increase in hotel occupancy rates between 2021 and 2022 and recovery to pre-pandemic operating levels contributed to the increase in energy consumption levels in 2022. Comparison between 2019 and 2022 consumption levels show a general decrease in energy and water consumption per square meter, but an increase in energy and water consumption per occupied room. This observation is largely attributed to the lag time between the resumption of hotel operations and the return of travelers

An overview of green retrofitting implementation in non residential existing buildings

Sustainability has been the latest value added service in the facility management field. However, the practice of sustainability in the facility management field is not well recognized and understood by the facility management team. As a result, building sector account to be the largest source of greenhouse gas emissions around the world. In fact, there is a strong business case for green building, yet green buildings represent the next phase of buildings. Since, the majority of the existing stock of buildings is not sustainably built and as it is not practically viable to demolish all the existing buildings, hence, one alternate solution is green retrofitting. However, the responses for green retrofitting are at very low rate. This paper reports the need to green retrofitting, reasons behind the limited number of green retrofitting implementation, and finally, a critical review of the existing body of knowledge on green retrofitting has been conducted. It is found that there has been no research conducted till to date on identifying the success factors for successful green retrofitting implementation
