  • Shades of GreenViewing High Performance (HP) DesignSoutheastern Facility Masters Conference Southeastern Association of School Business OfficialsNovember 18-20, 2008Little Rock, ArkansasLarry Schoff, PEConsultant to the US Department of Energys EnergySmart Schools Program

  • DOE EnergySmart Schools GoalsApproachImpact

    1. Promote 50% improved efficiency in new schools and major renovations or additions and 30% in existing buildings2. Develop and disseminate technical guidance, best practices and case studies which address existing buildings and new construction3. Identify sources of financing for high performance schools and provide tools that help stakeholders make a compelling business case4. Collaborate with national, regional, and local partners to promote healthy, high-performance schools

    Anticipated total energy savings from 700 schools: 0.002 quads with $14 million in cost savings to schools by 2020

    Catalyze significant improvements in energy efficiency by promoting schools that progress towards net-zero energy buildings

  • DOE EnergySmart Schools (cont.)New Construction and Major RenovationsPrimarily suburban districts and states with growing populationsOpportunity: Design in sustainability and high-performance from the outsetTarget: At least 50% energy savings over ASHRAE standardsExisting Buildings/RetrofitsPrimarily urban and rural districts, some driven by consolidations or need to upgrade aging infrastructuresTarget: At least 30% energy savings

  • Defining High Performance/Green/ SustainabilitySustainabilityDevelopment that meets the needs of the present without compromising the ability of future generations to meet their own needsGreenTo significantly reduce or eliminate the negative impact of buildings on the environment and on the building occupantsHigh PerformanceWhen a building, its systems and the occupants are operating effectively and efficiently

  • Defining High Performance/Green/ Sustainability (cont.)HP/Green Design Concepts apply to all building typesLEED-NC initially applied to allNow Building types having LEED documentsK-12 SchoolsShell BuildingsCampusCHPS Now adopted by several states

  • Defining High Performance/Green/ Sustainability (cont.)Life Cycle Cost vs. First CostAll of the decisions affecting this entire life cycle cost are made in the smallest portion of the building life cycle cost-design. High performance design must be incorporated from the start!

  • Defining High Performance/Green/ Sustainability (cont.)Integrated or Whole Building DesignWhole-building design considers all building components Integrates all the subsystems Design team should be fully integrated from the beginning; all the pieces must fit togetherBuilding design team can include architects, engineers, building occupants and owners, and specialists in areas such as indoor air quality, materials, and energy use.
