Traditional building retrofitting planning is a decision making process prior to the building retrofitting investment. Although the long term energy and financial issues of the retrofitting project are considered in some cases, the energy efficiency potentials due to the maintenance and operation of the retrofitted facilities are not sufficiently explored in existing studies. In the broad field...

This paper identifies the dilemma faced by the stakeholders of existing buildings in regards to a decision making process for energy retrofitting. This paper also identifies the missing stage viewed as the “integrity audit “which can lead to substantial savings in the area of building operation. The methodology is centered on identifying energy waste first, reducing the overall peak electrical ...

Given the current situation in which energy efficiency is considered as an important issue and the potential rise of greenhouse gas emissions, this paper analyzes and finds possible ways to improve energy efficiencies in buildings through an evaluation of existing business models and relevant policies. The first phase of analysis includes the selection of the best business model from the existi...

Since the introduction of the Green Mark Scheme in Singapore in January 2005, more than 650 projects have been awarded the Green Mark Award. In fact, from 2008, all new buildings must achieve the mandatory standard of a certified green building. However, the challenge is how to convert the existing stock of buildings in order for them to achieve the green mark standard. This study is motivated ...

In the context of an increasing number of retrofitting projects and greater consideration for the criteria of sustainability, architects and engineers are looking for a global optimization of existing buildings and therefore need to multiply comparisons between different possible variants. In order to structure the approach of this complex process, research carried out with the support of the S...

─This paper presents the retrofitting of beam-column joint using CFRP (Carbon Fiber Reinforced Polymer) and steel plate. This specimen was tested until failure up to 1.0% drift. This joint suffered severe damages and diagonal cracks at upper crack at upper column before retrofitted. CFRP were wrapped at corbel, bottom and top of the column. Steel plates with bonding were attached to the two bea...

BACKGROUND AND OBJECTIVE Continuous services provision of a hospital before and after a disaster is one of the most prominent issues that all people, especially the authorities must take into huge consideration. Concerning the experiences of previous earthquakes, the role and importance of nonstructural components becomes increasingly clear in the uninterrupted services of hospitals. In this st...

The built environment contributes around half of total greenhouse gas emissions and with 87% of residential buildings that we will have by 2050 already built, it is vital to adopt sustainable retrofitting practices. The question is: what are the viable solutions? One answer may be green roof retrofitting. The environmental benefits include reduced operational carbon emissions, reduced urban hea...

The building sector contributes a large proportion of the world’s total final energy consumption. As a result, considerable attention has been paid to energy efficiency in the building sector. At the current stage, building retrofitting is the most feasible and cost-effective method to improve building energy efficiency. This paper presents a multi-objective optimization model for life-cycle co...

Like many developed countries, energy efficiency and environment impact are the most important process in the development of power generation policy in India. A high ambient temperature reduces the air density and makes inlet air cooling (IAC) and steam injection gas turbine (STIG) attractive power augmentation method for existing regenerative gas turbine. With a high back work ratio and a high...
