GRESB vs. ENERGY STAR: Understanding Their Roles in Building Sustainability

GRESB vs. ENERGY STAR: Understanding Their Roles in Building Sustainability

In the real estate and building sectors, sustainability is becoming increasingly critical—not just as a goal but as a standard for operations and investments. Two prominent frameworks that guide sustainability practices are GRESB (Global Real Estate Sustainability Benchmark) and ENERGY STAR. However, these frameworks serve different purposes. GRESB is a comprehensive, voluntary tool for evaluating ESG (Environmental, Social, and Governance) performance, while ENERGY STAR is a regulatory standard for energy efficiency in the United States. This article explores how both frameworks can be leveraged to optimize sustainability efforts in real estate, highlighting their unique roles and complementary benefits.

Understanding GRESB and ENERGY STAR

What is GRESB?

GRESB is an industry-driven organization that provides standardized and validated ESG data to financial markets. It serves as a benchmark for sustainability performance in real estate portfolios, infrastructure funds, and other assets. GRESB assessments focus on management practices, environmental impact, social performance, and stakeholder engagement, offering companies an opportunity to demonstrate their commitment to sustainable investment practices.

GRESB is particularly valuable for institutional investors and property managers seeking to benchmark their sustainability efforts against peers and identify areas for improvement. Unlike ENERGY STAR, participation in GRESB is voluntary, making it a strategic choice for companies looking to enhance their ESG transparency and appeal to sustainability-focused investors.

What is ENERGY STAR?

ENERGY STAR is a program managed by the U.S. Environmental Protection Agency (EPA) that promotes energy efficiency across various sectors, including commercial real estate. Unlike GRESB, ENERGY STAR is not just a voluntary standard; it is a regulatory requirement for certain building types in the U.S. Achieving ENERGY STAR certification is essential for compliance, as it demonstrates that a building meets or exceeds energy performance benchmarks.

Buildings that earn the ENERGY STAR label typically use at least 35% less energy than average buildings and release 35% fewer greenhouse gases. This certification helps organizations reduce energy costs, meet federal and state regulations, and position themselves as leaders in energy efficiency.

Key Differences Between GRESB and ENERGY STAR

1. Regulatory vs. Voluntary

• ENERGY STAR: A mandatory regulatory standard in the U.S. for specific building types, essential for compliance with federal and state energy efficiency laws.
• GRESB: A voluntary framework used primarily by real estate investors and property managers to assess and improve their ESG performance, with no regulatory requirements attached.

2. Scope and Focus

• ENERGY STAR focuses exclusively on energy efficiency and performance, offering a straightforward metric to compare a building’s energy use against national standards.
• GRESB takes a broader view, evaluating environmental, social, and governance practices across an organization’s entire real estate portfolio.

3. Evaluation Criteria

• ENERGY STAR evaluates individual buildings based on actual energy consumption, using a scoring system to assess performance.
• GRESB conducts a portfolio-level assessment, evaluating a company’s overall ESG practices rather than focusing solely on energy efficiency.

4. Geographic Reach

• ENERGY STAR is primarily a U.S.-based program but is recognized globally as a benchmark for energy efficiency.
• GRESB operates internationally, allowing global real estate investors to benchmark their ESG performance.

5. Benchmarking and Scoring

• ENERGY STAR benchmarks energy performance against national standards and assigns a score based on a building’s energy efficiency.
• GRESB uses peer benchmarking to compare ESG performance among industry peers, providing a more comprehensive sustainability assessment.

The Benefits of GRESB and ENERGY STAR Certifications

GRESB Benefits:

• Enhancing ESG Transparency: Provides insights into a company's overall sustainability performance, which can attract ESG-focused investors.
• Competitive Advantage: High GRESB scores enhance reputation and can lead to better financing opportunities and investor interest.

ENERGY STAR Benefits:

• Regulatory Compliance: Ensures buildings meet mandatory energy efficiency requirements, reducing the risk of fines and enhancing marketability.
• Operational Cost Savings: ENERGY STAR-certified buildings typically have lower operating costs due to reduced energy consumption.

Shared Benefits: Both GRESB and ENERGY STAR certifications can enhance a company's sustainability profile, reduce operational costs, and improve market positioning.

Integrating GRESB and ENERGY STAR into Your Sustainability Strategy

Navigating Regulatory Requirements: Compliance with ENERGY STAR is non-negotiable for many building types in the U.S., ensuring that properties meet federal and state energy efficiency standards.

Using GRESB to Enhance ESG Performance: GRESB provides an additional layer of sustainability evaluation that complements regulatory frameworks like ENERGY STAR, offering a comprehensive view of an organization’s ESG performance.

Maximizing Value with Both Certifications: By integrating both ENERGY STAR and GRESB into their strategies, organizations can ensure compliance while also positioning themselves as sustainability leaders in the real estate market.

Conclusion

GRESB and ENERGY STAR are two essential tools in the sustainability toolkit for real estate owners and managers. While ENERGY STAR is a required standard for compliance with U.S. energy efficiency regulations, GRESB offers a voluntary framework for broader ESG assessment and improvement. By understanding the distinct roles and complementary benefits of both, organizations can better navigate the complexities of sustainability in real estate, ensuring compliance, enhancing investor appeal, and contributing positively to environmental goals.
