According to the United Nations Environment Programme, carbon emissions from buildings and construction account for nearly 40% of global carbon emissions. The International Energy Agency’s Tracking Buildings 2021 Report indicates that all new buildings, along with 20% of existing ones, must be zero-carbon-ready by 2030 to reach carbon neutrality by 2050. The building sector, spanning public, residential, and commercial buildings, directly and indirectly consumes 30% of the world’s final energy, contributing to approximately 55% of global electricity usage.
Small and medium enterprises (SMEs), or small and medium businesses (SMBs), play a crucial role in commercial energy consumption. For instance, in the UK, around 1.5 million small business premises account for 50% of commercial energy use, with the potential to cut energy consumption by up to 40%. As energy efficiency regulations tighten in line with international Net Zero Emissions commitments, commercial landlords and small business tenants are driven to innovate. Nevertheless, the Energy Systems Catapult found that SMEs frequently mention a “lack of time, money, or confidence in available solutions” as barriers to implementing energy-saving measures.

Standards and Certifications for Evaluating Green Building Performance
Organizations like the World Green Building Council (WGBC) and the Green Building Initiative provide valuable guidance for the construction industry to adopt better building practices. Recognized sustainability certifications, such as the Building Research Establishment Environmental Assessment Method (BREEAM), Leadership in Energy and Environmental Design (LEED), and WELL Building Standard, offer methodologies, metrics, and benchmarks to assess sustainability performance throughout a building’s lifecycle. The following seven criteria influence design decisions, material selection, and construction scheduling:
- Energy Efficiency: Minimize energy consumption across systems including lighting, heating, and cooling, and incorporate renewable energy sources.
- Water Efficiency and Conservation: Decrease potable water use for appliances and processes, and minimize water loss due to leaks.
- Emissions: Lower carbon dioxide emissions and reduce concentrations of harmful chemicals like volatile organic compounds (VOCs) from materials and furnishings.
- Indoor Environment Quality: Enhance air quality, lighting, acoustic performance, and thermal comfort.
- Materials and Resource Use: Source materials responsibly, ensuring low embodied impact throughout their lifecycle including extraction, processing, and recycling.
- Operations and Maintenance: Maintain the built environment effectively to ensure it meets its intended function throughout its lifecycle.
- Waste Reduction: Implement waste reduction, recycling, and reuse programs to manage construction and operational waste sustainably.
These areas of focus are typically included in green building assessments. For more insights on how customers have successfully implemented sustainability solutions on AWS, read more on this blog post.
Five Key Areas for Enhanced Green Building Performance
The World Economic Forum, in conjunction with JLL, established the Green Building Principles as part of The Action Plan for Net-Zero Carbon Buildings in October 2021. These principles promote commercial and technical advancements across five key areas to make buildings and cities more livable, sustainable, resilient, and affordable.
- Adopting a Data-Driven Approach: Construction management teams should calculate a comprehensive carbon footprint of their real estate portfolio to pinpoint major emission sources and devise effective strategies. This may involve integrating data from existing sources, utilizing IoT sensors, and forecasting emissions as interventions are executed. Enhance building systems with AWS IoT services to create smart building solutions that collect and aggregate data from on-site management platforms, such as lighting and HVAC systems.
- Setting Goals Along the Journey: Executives should establish interim targets for 2030 to achieve net-zero carbon emissions by 2050 or sooner. Effective goal-setting requires a clear vision and collaboration among various stakeholders. Connect with the AWS Executive Briefing Center to strategize and expedite goal achievement.
- Tackling Embodied Carbon: Measure and document embodied carbon emissions associated with materials and construction processes using a whole lifecycle approach. Embodied carbon can often surpass operational carbon emissions throughout a building’s lifespan. As business operations expand, emissions monitoring tools should scale accordingly. High-quality carbon offsets may still be necessary to address residual emissions.
- Focusing on Clean Energy: Define energy efficiency targets and identify necessary optimizations to meet standards. Aim to maximize energy sourced from renewable on-site and off-site resources. The International Performance Measurement and Verification Protocol (IPMVP) offers a framework for verifying project performance and quantifying energy and cost impacts.
- Ensuring Continuous Learning: Stay updated on the latest trends and practices in sustainable building. For more information, this video provides excellent resources on the topic.
