RMI Deep Retrofit Needs Assessment 1. Financing: none available 2. Risk/litigation: never done it before; don’t want to reduce installed cooling capacity, don’t want to force on tenants, etc. 3. Business case: rapid building turnover; more compelling alternative investments, etc. Value of energy efficiency 4. First cost: cost of technologies and of services, etc. 5. Split incentives: tenant/landlord; costs of sub-metering, etc. 6. Retrofit process: time-consuming phases; non-standardized analysis/audit procedures; difficult to engage all stakeholders 7. Design: few capable engineers; cream-skimming habits; no incentives to maximize savings, etc. 8.

Why did we find mostly “Renewals”* * “renewals”, “major renovations”, “whole building upgrades” all denote that the building had significant changes to the interior, structure and/or activity type in addition to efficiency measure improvements. – Real Estate Industry is Repositioning Assets – Improving existing buildings is the best value now – Where deepest savings are more likely to occur – More public and ‘green firms’ continuing to renovate buildings during the economic downturn – Larger scopes are more likely to be documented – Single measure or ‘shallow’ retrofits are less likely to be found in a search (more contractor driven) Deep Savings Webinar 6/30/2011
Digging into buildings and data • Best of Best – advanced mechanical, daylighting, advanced controls, natural ventilation plus pay attention • Worst of Best – usually no clue that building not performing, mostly operational issues, occasionally design or construction; Cx post occupancy should fix most • Ongoing measured performance of buildings is critical – Metering and monitoring Deep Savings Webinar 6/30/2011
Cross-Cutting Themes • Integrated design is more critical to the development of low/zero-energy buildings than is any given technology. • Moving beyond design and construction into operations, plug loads, process energy and other “unregulated loads” is a critical step. • There is need for a consistent, long-term metric to measure the performance of buildings and policy, such as the Zero Energy Performance Index (zEPI). • More measured performance data at the case-study level, and at the system level to support owner and private financing.

  • 65. Why did we find mostly “Renewals”* * “renewals”, “major renovations”, “whole building upgrades” all denote that the building had significant changes to the interior, structure and/or activity type in addition to efficiency measure improvements. – Real Estate Industry is Repositioning Assets – Improving existing buildings is the best value now – Where deepest savings are more likely to occur – More public and ‘green firms’ continuing to renovate buildings during the economic downturn – Larger scopes are more likely to be documented – Single measure or ‘shallow’ retrofits are less likely to be found in a search (more contractor driven) Deep Savings Webinar 6/30/2011
  • 66. Digging into buildings and data • Best of Best – advanced mechanical, daylighting, advanced controls, natural ventilation plus pay attention • Worst of Best – usually no clue that building not performing, mostly operational issues, occasionally design or construction; Cx post occupancy should fix most • Ongoing measured performance of buildings is critical – Metering and monitoring Deep Savings Webinar 6/30/2011
  • 67. Cross-Cutting Themes • Integrated design is more critical to the development of low/zero-energy buildings than is any given technology. • Moving beyond design and construction into operations, plug loads, process energy and other “unregulated loads” is a critical step. • There is need for a consistent, long-term metric to measure the performance of buildings and policy, such as the Zero Energy Performance Index (zEPI). • More measured performance data at the case-study level, and at the system level to support owner and private financing.
