The Boulder Valley School District (BVSD) in Colorado is implementing a comprehensive energy strategy to reach net-zero energy and an 80 percent reduction in greenhouse gases by 2050. Supported by a $576.5 million bond approved in 2014, the district is utilizing deep retrofits, retrocommissioning, and new construction across its portfolio of over 50 buildings. In partnership with RMI, BVSD has adopted an integrative design process and a Sustainable Energy Plan (SEP) to reduce energy use intensity (EUI) from an average of 65 to less than 30 kBtu/SF. The initiative aims to save nearly $500,000 annually in utility bills and serve as a model for other U.S. school districts.

The paper examines how urban development decisions regarding buildings and transport infrastructure can 'lock in' future greenhouse gas emissions. By comparing a reference scenario with an aggressive 'urban action' scenario, the authors estimate that urban policy-makers can avoid committing approximately 45 Gt CO2 of cumulative future emissions by 2030 through energy-efficient technologies and compact urban design. The analysis emphasizes that current infrastructure already commits roughly 800 Gt CO2, meaning the 1,000 Gt CO2 global carbon budget for limiting warming to 2°C could be exceeded before 2020 if current trends continue.

The report examines clean energy financing tools used by six U.S. states and Germany to scale up renewable energy and energy efficiency investments. It highlights the role of 'green banks' and other mechanisms in reducing financial risks for the private sector and overcoming barriers like high upfront costs and limited technical understanding among financiers. Case studies include Connecticut and New York's green banks, Pennsylvania and Kentucky's use of the Warehouse for Energy Efficiency Loans (WHEEL), Iowa's revolving loans, and Massachusetts's Mass Save HEAT Loan. The report concludes that these tools can help states achieve Clean Power Plan targets by leveraging limited public funds to attract significant private capital.

The document argues that deep energy retrofits—defined as integrated measures reducing energy consumption by 30 percent or more—are often undervalued because investors focus solely on energy cost savings. It proposes a 'deep retrofit value' (DRV) approach that incorporates five key value elements: initial development costs, non-energy operating cost reductions (such as maintenance and insurance), risk analysis, tenant-based revenues (via higher rents and occupancy), and increased sales revenues driven by higher net operating income and lower cap rates.

The document outlines the GSA's National Deep Energy Retrofit (NDER) Program and provides a framework for achieving energy savings of 50% or more in federal buildings. It highlights the effectiveness of bundling energy conservation measures (ECMs), engaging diverse stakeholders, and utilizing a 'technical potential' tool to identify aggressive energy goals. Case studies, such as the Almeric Christian Federal Building, demonstrate the feasibility of net-zero energy through the ESPC process, while data analysis shows that NDER projects achieved an average of 38% energy savings, more than double the 18.5% average of non-NDER federal ESPC projects.

The document outlines eleven strategic solutions to help companies achieve net-zero energy in corporate real estate. It categorizes these into 'organize' (securing C-suite support and multi-disciplinary teams), 'capitalize' (investing in smart building management, health-focused design, and external financing), and 'optimize' (using value-based approaches and portfolio-wide investment allocation). The report emphasizes that energy efficiency should be the first priority due to its cost-effectiveness and potential to improve employee productivity.

The GSA's National Deep Energy Retrofit (NDER) program demonstrated that deep energy retrofits can achieve significantly higher savings than typical federal projects, with Round 1 projects averaging 38% energy savings compared to 21% in other agencies. The report details a collaborative workshop held in April 2014 to identify process improvements, technical barriers, and economic strategies to reach the goal of 50% or more energy savings. Key recommendations include adopting integrative design, incorporating operations and maintenance (O&M) into performance contracts, and combining energy efficiency upgrades with appropriated renovation funds.

The 2014 International Solar Decathlon at Versailles showcased sustainable housing designs from over 20 universities globally. The event emphasized the synergy between innovative products, such as polyisocyanurate insulation, and student ingenuity in addressing energy efficiency and urban retrofitting. Notable projects included Appalachian State University's modular town home, the Berlin Rooftop Project's use of abandoned roof space, and Delft University's 'second skin' for poorly insulated Dutch townhomes.

The executive summary introduces a guide for owner-occupants to capture the full value of deep energy retrofits, which are defined as those reducing energy consumption by 50 percent or more. It argues that these investments generate significant, quantifiable business value through non-energy benefits, such as improved employee health, productivity, and risk management. The document presents the RMI Retrofit Value Model, which links design and execution practices to direct and indirect outcomes, ultimately impacting property and enterprise performance. It details nine specific value elements—ranging from reduced health and employee costs to enhanced property-derived revenues—that professionals can use to build a comprehensive business case for deep retrofits.

The document argues that deep energy retrofits—those reducing energy consumption by 50% or more—generate significant, often overlooked business value.
