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

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
• 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
Smart Growth Principles

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
![Page 9: RCD CDHO - EE in HOME Workshop](https://reader033.vdocuments.us/reader033/viewer/2022052900/55626fe6d8b42a14048b58c7/html5/thumbnails/9.jpg)
• High content slag concrete to reduce use of portland cement, CO2emissions, 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

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
