    RCD CDHO - EE in HOME Workshop RCD CDHO - EE in HOME Workshop Presentation Transcript

    • Energy Efficiency, Renewables, and Green Building in HOME Housing Programs Lihbin Shiao, Consultant Project Manager Resources for Community Development Oxford Plaza/David Brower Center 2200 Oxford Street, Berkeley, CA San Jose Workshop June 10, 2008
    • RCD Greenbuilding Strategy • Priority – Measures resulting in beneficial outcomes to residents – Indoor Air Quality – Energy & Utility cost savings – Smart growth also promotes access to resources – Durable finishes – Access to natural resources • Secondarily – Sustainable building practices – Reduce impact of construction on environment
    • Sustainable Development and Green Building USGBC Shinsei Gardens LEED for Homes Oxford Plaza and David Brower Center Fox Courts Los Medanos Village Northgate Apartments Breakers at Bayport
    • Typical RCD Green Features Bioswales Steel Framing Infill Sites Photovoltaic Panels Formaldehyde Free Cabinets Brownfield Remediation & Insulation Recycled Rainwater for Irrigation Native Plant Landscaping Recycled Content Carpet Energy Star Appliances and Light Fixtures Natural Linoleum High Content Slag in Concrete
    • Overview of Oxford Plaza & Retail Case Study • 97 units of affordable housing – 30% - 60% AMI + PBS8 • 8,500 sq ft ground floor retail • Co-located with the David Brower Center – 50,000 sq ft including non-profit office space, a theatre, art gallery, and Back to Earth sustainable restaurant • Co-located with a City parking garage
    • Green Building Measures Smart Growth Principles • High Density Development (97 units / acre for total site, 143.7 units/acre for the housing parcel) • Transit Oriented, Urban Infill Development Reduction of Construction Waste • 75% of total project construction and demolition waste diverted from landfill
    • Energy Efficiency • Solar thermal hot water system on the roof for heating and hot water • Radiant hydronic in slab system for heating • Exceeds Title 24 standards for energy efficiency by more than 15% • Energy Star appliances and energy efficient lighting tttthroughout • Awnings on south facing windows which reduce the tttneed for summertime cooling and wintertimetheating
    • Recycled Content & Indoor Air Quality • Use of recycled-content building materials • CRI “Green Label” rated carpets throughout units and linoleum floors in kitchens; • Mechanically assisted ventilation • Low VOC paints and no VOC adhesives
    • Resource Conservation • High content slag concrete to reduce use of portland cement, CO2 emissions, and water • Low flow toilets and showers • 80% California Native and Mediterranean Species (climate appropriate) or edible plant landscaping that require little summer watering, once established • Planting grouped in hydrozones and are watered through a high- efficiency irrigation system, e.g. drip line irrigation
    • Resource Conservation • All metal framing (28% recycled content) which results in minimizing use of wood in the project. • Rainwater will be collected from Oxford Plaza and directed to a cistern in the Brower Center when there is capacity in the cistern • Durable finishes and cabinets with longer useful life
    • Challenges in Implementation of Green Measures • New technologies - trial and error & additional cost & time – Slag concrete – Metal framing – Radiant tubing • Financing – Increased cost per unit – Capturing savings through utility allowances to fund energy efficient measures • Other priorities for resources
    • Strategies to Promote Green HOME Housing • Eligibility for HOME Funds • Acceptance of Increased Costs – Upfront & in Change Orders • Some jurisdictions give points for inexpensive rating systems, e.g., Build It Green
