The selection of buildings for refurbishment is a multi-objective problem and it should be based on integrated assessment of the current performance of the buildings. Accurate assessment allows the development of strategies for the optimisation of building performance and the selection of appropriate and most efficient refurbishment measures. This paper presents a computer-based integrated building performance assessment methodology based on the multiple-criteria approach. A case study from the Šiauliai district, Lithuania, illustrates the proposed methodology in use. The assessment results indicate what are the worst performing buildings and help with the selection of appropriate refurbishment measures and estimation of possible outcomes.

“…Based on the gaseous emission of a material in terms of unit mass (e.g., kg of CO 2 emission per kg), the masses of the materials associated with different components can be converted to their environmental impact. The basic parameters associated with CO 2 emissions for different structural and non‐structural components have been investigated by and . Generally, the amount of CO 2 associated with the materials used in a building component can be calculated based on the mass quantity of material and the unit emission coefficient of unit quantity of material (e.g., kg CO 2 /kg) .…”

Sustainability and resilience are issues that are recognized worldwide, and increased attention should be placed on strategies to design and maintain infrastructure systems that are hazard resilient, damage tolerant, and sustainable. In this paper, a methodology to evaluate the seismic sustainability and resilience of both conventional and base-isolated steel buildings is presented. Furthermore, the proposed approach is used to explore the difference between the performance associated with these buildings by considering the three pillars of sustainability: economic, social, and environmental. Sustainability and resilience are both considered to cover a comprehensive performance-based assessment content. The uncertainties associated with performance and consequence evaluation of structural and non-structural components are incorporated within the assessment process. The proposed performance-based assessment approach is illustrated on conventional and base-isolated steel buildings under given seismic scenarios. 54% of energy consumption in the United States is caused by building [4]. Additionally, buildings account for a paramount portion of greenhouse emission. Although building rating systems, such as LEED [5], evaluate the greenness of new and existing structural systems, the ratings do not measure building hazard performance, which can impact building sustainability performance as well. Hazardresistant and green structure design that aims to improve building performance is needed [6,7].Several improvements have been made in codes to increase seismic resistance of buildings [8]. The protection associated with non-structural components, equipment, and contents of buildings under seismic hazard is gaining increased attention in building design provisions, such as the International Building Code [9] incorporating more stringent design requirements for non-structural components. Loss associated with non-structural components could be much larger than that of structural components [10]. The concept of base-isolation can be adopted to reduce the floor acceleration of buildings, consequently, reduce the damage of acceleration sensitive non-structural components. However, because of the high initial construction cost, the performance benefits associated with base-isolated buildings are not recognized. Several studies have investigated the nonlinear seismic performance of isolated systems [10][11][12][13]; the isolation device can reduce the seismic demands compared with a base-fixed building. [14] investigated the cost and benefit of retrofitting reinforced concrete frame buildings and concluded that this benefit can outweigh the repair cost within the lifecycle. [15] concluded that an isolated building is more cost effective when the life-cycle is longer than 250 years considering the direct loss only.[10] evaluated cost-benefit of several common retrofit solutions for older RC frame buildings and showed that the cost-effectiveness became more significant when fatalities were considered. However, the sustainability per...

“…In addition to these, it has been reported that the OE contribution from buildings to total energy consumption in the United States, European Union and the United Kingdom are 40%, 37%, and 29% respectively (Pérez-Lombard et al 2008, Environmental Protection Agency (EPA) 2009). In states that rely heavily on a service driven economy, for example Hong Kong, this proportion can be as high as 80% (Chau et al 2012). The factors contributing to this and requirement for its improvement have been previously extensively discussed .…”

The incorporation of sustainability principles into structural engineering design of buildings has been poorly conducted. Numerous Green Building Ratings Systems (GBRS) exist to attempt to improve this. These systems have focused largely on Operational Energy (OE) efficiencies and management aspects to attain high assessment scores. Previous research has identified this focus to be inconsistent with published data in comparison with the overall Building Life Cycle (BLC) impacts. The consideration of structural elements, through which structural engineers have the greatest ability to influence outcomes, was shown to account for over 20% of BLC considerations. However these elements only account for approximately 10% of points achievable under existing GBRS. The advent of Zero Energy Buildings (ZEB) will result in the gap between these values increasing, further highlighting the requirement for the improvement in the focus of existing GBRS if they are to achieve any quantifiable overall improvements to buildings environmental performance. This research builds on the outcomes of previous research and the identification of these discrepancies. The research proposes methods to improve the focus of GBRS in order to bring them into line with the current understanding of total BLC energy consumptions and environmental impacts.
