Sustainable building adaptation
How to adapt existing building stock is a problem being addressed by local and state governments worldwide. In most developed countries we now spend more on building adaptation than on new construction and there is an urgent need for greater knowledge and awareness of what happens to commercial buildings over time.
Sustainable Building Adaptation: innovations in decision-making is a significant contribution to understanding best practice in sustainable adaptations to existing commercial buildings by offering new knowledge-based theoretical and practical insights. Models used are grounded in results of case studies conducted within three collaborative construction project team settings in Australia and the Netherlands, and exemplars are drawn from the Americas, Asia, Japan, Korea and Europe to demonstrate the application of the knowledge more broadly.
Results clearly demonstrate that the new models can assist with informed decision-making in adaptation that challenges some of the prevailing solutions based on empirical approaches and which do not accommodate the sustainability dimension. The emphasis is on demonstrating how the new knowledge can be applied by practitioners to deliver professionally relevant outcomes.
The book offers guidance towards a balanced approach that incorporates sustainable and optimal approaches for effective management of sustainable adaptation of existing commercial buildings.

Energy Auditing for Efficient Planning and Implementation in Commercial and Residential Buildings
The ideology of ensuring energy-efficient design and construction of buildings by providing minimum requirements is the core objective of this work. Energy audit was conducted to improve the design of the building with incremental requirements to further enhance the energy efficiency. The Energy Conservation Building Code (ECBC) has been modified extensively over the years, starting from its initial deployment in the year 2011 to its latest modifications in the year 2019. The energy conservation standards in ECBC apply to building envelope, heating ventilation, air conditioning, lighting, service water heating, and electric power distribution. It should also be ensured that all-electric systems, transformers, energy-efficient motors, and diesel generators must meet the regulated set of mandatory requirements. From among the various software types that have been approved for ECBC design and application, this study has employed Energy Plus software to simulate the design based on the given input and the selected location. The location that has been chosen for this study was Bhubaneshwar, India. All necessary details ranging from latitude, longitude, weather, time zone, elevation, building area, lighting, heating, cooling, and much more have been covered in the simulation. Utilizing ECBC regulated standards for an energy-efficient building design has resulted in an increase in the energy savings by 27.4%, and thus, the building qualifies to be regarded as an ECBC compliant building.

Potential of artificial intelligence in reducing energy and carbon emissions of commercial buildings at scale
Artificial intelligence has emerged as a technology to enhance productivity and improve life quality. However, its role in building energy efficiency and carbon emission reduction has not been systematically studied. This study evaluated artificial intelligence’s potential in the building sector, focusing on medium office buildings in the United States. A methodology was developed to assess and quantify potential emissions reductions. Key areas identified were equipment, occupancy influence, control and operation, and design and construction. Six scenarios were used to estimate energy and emissions savings across representative climate zones. Here we show that artificial intelligence could reduce cost premiums, enhancing high energy efficiency and net zero building penetration. Adopting artificial intelligence could reduce energy consumption and carbon emissions by approximately 8% to 19% in 2050. Combining with energy policy and low-carbon power generation could approximately reduce energy consumption by 40% and carbon emissions by 90% compared to business-as-usual scenarios in 2050.
AI reduces building energy and emissions in design/construction, equipment, occupancy, and control/operation. By accelerating high-efficiency and net-zero buildings, AI could cut energy and emissions by 40-90% by 2050 combined with adequate policies.

Developing an Automated Workflow for Non-Residential Building Retrofit as a Function of Usage
Many countries have committed to zero carbon emissions by 2050 and have set ambitious targets for net-zero energy buildings in the coming years. To achieve this goal, highly insulated envelopes need to be combined with renewable energy generation. Energy conservation measures (ECM)s are needed as practical steps toward higher energy efficiency. At the same time, it is important to consider the building occupants' interaction with the energy supply and distribution systems as well as the control of thermostats, window openings, shading systems, or similar. Quantifying the occupant-related effects on the building energy can help to improve the building performance accuracy and reduce grid electricity stress. This paper proposes an automated workflow for analyzing the retrofits of non-residential buildings and the impact of their usage. The methodology is structured to follow three consecutive steps: (1) Extracting and modifying a Geo-based geometry model and assign attributes; (2) Energy modeling setup and parametric investigation; (3) Evaluating multi-objective scenarios for a range of construction, usages, and occupancy patterns. The methodology is applied to a case study on the re-use of an existing unoccupied industrial building complex located in Montreal, Canada, as part of a C40 re-inventing cities competition. The building geometry and surrounding context are processed and connected to an energy simulation software in order to examine a range of construction modifications, mechanical systems together with occupancy patterns. A construction and occupancy library has been developed to enrich the parametric investigation of the study. Various scenarios were investigated in a parametric process to guide design decisions for improved building performance. Different retrofit strategies that achieve the targeted objectives were compared in multiple aspects, such as energy, operational carbon, and embodied carbon. The presented workflow has the potential for expansion towards similar cases and building types. The methodology aims to support the decision-making for multiple stakeholders such as building owners, architects, engineers, and policymakers. Future investigations include developing a workflow that upscales the methodology to a broader spatial scale in a bottom-up approach.

The Diffusion of Energy Efficiency in Building
We analyze the diffusion of buildings certified for energy efficiency across US property markets. Using a panel of 48 metropolitan areas (MSAs) observed over the last 15 years, we model the geographic patterns and dynamics of building certification, relating industry composition, changes in economic conditions, characteristics of the local commercial property market, and the presence of human capital, to the cross-sectional variation in energy-efficient building technologies and the diffusion of those technologies over time. Understanding the determinants and the rate at which energy-efficient building practices diffuse is important for designing policies to affect resource consumption in the built environment.
