Sustainable Asset Management

Developing a software package for calculating GHG emissions of stationary and mobile assets

This work was a collaborative research project with Fiix. We recently developed a software package to calculate the carbon dioxide (CO2) equivalent and the total GHG cost of assets emitting Scope 1 or 2 emissions, or both. Scope 1 are direct GHG emissions, such as emissions from internal combustion sources. Scope 2 are the emissions from purchased electricity, heat, cooling, and steam. The location-based emission factors for all countries, provinces, states or regions have been aggregated in the package to make it globally applicable. This package can be utilized to provide estimates of the CO2 equivalent and the GHG costs of an asset during its operation phase.

A model to control environmental performance of project execution process based on greenhouse gas emissions

We have developed a model using several proposed metrics to estimate and measure the GHG emissions of a construction project. The model can be used at any point in time over the life of the project, and can be applied to any type of projects in an organization that aims to reduce its carbon footprint. The same structure can be applied to monitor and control any other environmental impact associated with project execution process.

Economic and environmental optimization of assets utilization, retrofit and replacement decisions

We are developing mathematical models for optimal planning of assets utilization, retrofit, and replacement, which results in the minimum total cost and environmental outcomes. Moreover, we are designing and developing a decision support tool based on the optimization models, which in addition to the optimal plan, provides the possibility of assessing the impact of various planning options and parameters uncertainty.

Energy-efficient process planning, production scheduling, and maintenance strategy in energy-intensive industries

We are determining jointly optimal process plans, production schedules, and maintenance policies for energy-intensive manufacturing processes, which result in minimum energy consumption, manufacturing cost, as well as production makespan.
