Abstract
Recently, attempts have been made to improve the efficiency of energy use in buildings in many countries all over the world. Most hotel buildings are deemed as unprofitable non-energy efficient constructions whilst renovations to their energy-efficient system are still non-resolute or unexplored. The Retrofit Energy Efficiency Sustainable Hotel Building (REESH) is not only the best opportunity to minimize energy use, but it also enhances environmental protection, cost-efficient use of resources and health benefits for residents. Sustainable development strategies need a variety of modification towards the sustainability of existing buildings. Improvements can be made based on the concept of Integration Sustainable Development (ISD) on existing buildings by retrofit. The REESH projects are in compliance with the sustainable model development strategy and can be done through the Energy Performance Contract (EPC) method which uses performance indicators to measure the efficiency of the REESH project. This study adapts the energy efficiency strategies to produce energy efficient hotel buildings through the energy contracting method. It also produces energy efficiency modifications to be sustainable in Malaysia. The main objective of the study is to identify the Key Performance Indicators (KPIs) and Critical Success Factors (CSF) for hotel building renovations using the EPC methods. The second objective is the development of the REESH model that relates to REESH‘s CSF and KPI using the Decision-Making Trial and Evaluation Laboratory Process (DEMATEL), hybrid method and model comparison. The third objective is to find out the barriers to the implementation of the guidelines. The last objective entails the evaluation of the Guideline Retrofit Energy Efficiency for Hotel (GREESH) by taking into consideration the REESH‘s model which is required to specify its benefits and limitations. The academic experts and private parties reviewed the validity of GREESH and Model evaluations. The main outcome of this study is the establishment of the REESH model and GREESH guideline that links the 53 CSFs, 8 KPIs and sustainable dimensions for REESH building in Malaysia. From this study it is observed that the most important factors in REESH are project objectives control method, contract type, access to technology, contract award method, effective coordination, organizational leadership capability, accurate measurement and verification, mutual trust, rational organizational structure, time management, and technical background staff related to REESH building in Malaysia. The concluding remark of the research is a proposed model for establishing a retrofit guideline towards the RESSH buildings in Malaysia by using the EPC method.
