Efficient project delivery in the context of contemporary construction management is dependent on large volumes of data. However, due to pertinent challenges underlying implementation, easy access to key construction management data remains a significant hurdle. Management is quickly transforming to facilitate the employment of predictive decision-...
Chapter
Full-text available
Industrial greenhouse gas (GHG) emission reporting has been an error-prone process due to the lack of universally accepted guidelines. Challenges pertaining to industrial GHG emission quantification consist of enhancing the accuracy of estimates by reducing the risk of double-counting. Currently, GHG emissions from overall natural gas use and large...
Article

Adopting critical life cycle thinking is crucial when deciding on how to implement building retrofits. This article first evaluates innovative and proven building energy retrofits through a life cycle t...
Article
Traditionally, green building rating systems have used a building-centric sustainability evaluation. This research challenges the status-quo of building sustainability assessment with a user-centric approach. A user-centric sustainability evaluation can provide a comprehensive assessment of building from a user's perspective. An ideal user-centric...
Article
A significant share of federal and regional infrastructure budgets is spent on constructing, maintaining, repairing, and replacing road infrastructure. Due to its magnitude, sustainable road construction practices can support national sustainable development goals (e.g. The Federal Sustainable Development Strategy of Canada). However, the quest for...
Article
Full-text available
The residential sector consumes about 50% of the electricity produced from fossil fuels in Saudi Arabia. The residential energy demand is increasing. Moreover, a simple building energy performance assessment framework is not available for hot arid developing countries. This research proposes an energy performance assessment framework for residentia...
Article
Change iterations in construction create uncertainties and make the project management dynamic and unstable. Published literature shows that 30% of the construction cost is attributed to rework. Moreover, change orders are considered as the largest source of construction waste. Construction professionals have to make change decisions based on their...
Article
Supplying the energy needs of a community through renewable energy sources is a vital aspect in developing sustainable communities. Many variations and uncertainties affect the development of a renewable-powered net-zero energy system. Community developers face challenges in making the investment decisions when planning community-level renewable en...
Article
Full-text available
Occupant behavior in residential buildings has a direct impact on the effectiveness of energy-saving measures. In order to realize a buildings’ carbon mitigation targets, the impact of individual occupancy profiles needs to be integrated with building simulation models. This paper introduces a decision support framework as a potential solution to m...
Conference Paper
Full-text available
Green building construction has received global interest over the past two decades. The definition of a green building has evolved from energy-efficient buildings to net-zero buildings, and now is expanding towards net-positive buildings. Even though these concepts entail significant environmental benefits, they largely overlook life cycle environm...
Conference Paper
Full-text available
Energy-related decision making for a building is a demanding task, due to the challenges associated with energy system performance prediction. Performance prediction can be done either with simulation tools or by referring to the building energy performance databases. However, in Canada, interactive building energy performance databases that allow...
Article
Construction project proposal evaluations received much attention during the recent years due to increased awareness of sustainability, value for money, and transparency. The bid evaluation matrix is the commonly used method in the construction industry for project proposal evaluation. The subjective judgments used for evaluation criteria are assoc...
Article
The building industry has a high energy consumption, which results in natural resource depletion, land use, ecosystem degradation, atmospheric pollution, and many other environmental impacts. Therefore, in modern construction, while maintaining a satisfactory and comfortable interior environment, less energy consumption and resource use is a major...
Article
Full-text available
Residential sector accounts for 17% of domestic energy use and 14% of the greenhouse gas emissions in Canada. Improving the energy performance of the Canadian residential building stock is vital in achieving climate action goals. A comprehensive review of popular building energy rating systems noted their lack of life cycle thinking. The scope of t...
Conference Paper
Full-text available
Post-occupancy performance evaluation (POPE) is an important process in the life cycle management of built infrastructure. Since Canadians spend approximately 80% of their time indoors, operational management of built environment is of extreme importance. Due to the increased popularity of multiunit residential buildings (MURB) in urban areas, ther...
Article
Small-sized urban neighbourhoods are facing challenges to achieve their sustainability objectives due to lack of resources and their limited economies of scale. Establishing benchmarks and evaluating the sustainability indicators (SIs) for such neighbourhoods using a fixed-point scoring approach without addressing the uncertainties associated with...
Article
Improving the environmental performance of built environments has received wider interest in the recent past. Asset management is an under-utilized strategy to enhance and maintain desired environmental performance of a building at low life cycle costs (LCC). Current asset management decision-making methods are not fully capable of incorporating fu...
Article
Full-text available
Increased awareness of climate change has precipitated more stringent mitigation targets. Public sector institutions in Canada are committed to becoming carbon neutral to attain a leadership position in climate change mitigation-related initiatives. Recent statistics reveal that buildings account for the majority of the corporate carbon footprint o...
Article
Climate-conscious development is a topic which has received widespread attention. One consequence of this is the prominence of greenhouse gas (GHG) emissions reduction targets set at various administrative levels (i.e. global, national, provincial and local governments). Despite the global interest, current models are incapable of integrating GHG e...
Article
Even though there is a large body of knowledge related to buildings, only a limited number of examples with a focus on asset management exist in published literature. More importantly, current literature lacks rating systems that support tactical and operational management of building infrastructure. This paper addresses the aforementioned knowledg...
Article
Ongoing climate action programs are prompting more stringent energy performance standards for buildings. Consequently, energy retrofitting of existing buildings has become a common climate action initiative around the world. Building owners are keen to assess the technical and financial feasibility of energy retrofitting in pre-project planning sta...
Article
Full-text available
The building industry has regularly been criticized for resource exploitation, energy use, waste production, greenhouse gas emissions, and impacts on the landscape. The growing population demands more built environment to accommodate the socioeconomic wellbeing. Adopting conventional construction practices would continue the aforementioned issues....
Article
Full-text available
During the recent past, the individual responsibility of climate change mitigation has been acknowledged by the society at large. Energy planning is pivotal in mitigating GHG emissions and adopting climate resilient strategies. However, community level energy planning has been overlooked in the urban development planning and the approval process. M...
Article
The building stock in the world consumes approximately 40% of the energy and emits one third of the total greenhouse gases emissions (GHG). Improving the energy efficiency in buildings is vital to address the climate change and achieve energy independence (i.e. to become net-zero energy). Improving energy performance in existing buildings has been...
