Transcript and Presenter's Notes

Title: Action Starts at Home:


1
Action Starts at Home
  • Building Sustainable Neighborhoods and Green
    Housing for Nantucket Residents

2
Background
3
Housing Nantucket
  • Private, non-profit organization
  • Creating sustainable housing opportunities for
    Nantucket residents
  • Through three areas of focus
  • Rental Services
  • Homeownership Services
  • Technical Assistance

4
Our Role in Affordable Housing
5
What is Affordable Housing?
  • Generally serves those earning below 100 of Area
    Median Income (84,400)
  • Housing Needs Covenant serves those earning up to
    150 of AMI
  • The residents are town employees, service
    workers, construction workers, and health
    workers.
  • Scattered sites Surfside, Tom Nevers

6
Why do we need housing?
  • Serves those that cannot fit within the community
    expectations for costs
  • Provides sustainable, long term housing
  • Provides supportive services for those who may
    not have access to them
  • Creates a well rounded community

7
Affordable and Green?
  • One of the most important connections
  • Create solutions between those who earn less and
    lowering energy costs
  • Housing developers have an opportunity to create
    holistic visions for their developments
  • Ability to concentrate goals and outcomes for the
    projects

8
What are the steps to making green work?
  • Better basic design
  • Better neighborhood development
  • More responsive to community
  • Setting a basic level of green
  • Developing a case study

9
Better Design, Better Neighborhoods
10
Defining Terms
  • Green Neighborhood A neighborhood that is
  • moderately dense
  • range of uses
  • designed for people and pedestrians first
  • network of paths and streets
  • human-scaled buildings
  • pedestrian-oriented street design
  • green elements network of green spaces,
    street trees, significant private landscaping
    (including possibly green roofs)
  • Buildings are often green buildings
  • Green infrastructure low-impact stormwater
    management to district energy systems

11
Methods for Green Neighborhoods
  • Cluster Development
  • Conservation Subdivision
  • Low-Impact Development
  • Neo-Traditional Design

12
Envisioning a Green Neighborhood
  • Several criteria can be used
  • Most common criteria is the LEED standard
  • Leadership in Energy and Environmental Design
  • Developed by the US Green Building Council

13
The Big DDensity
14
So, what Density works?
  • New England small towns tend to have between 3
    and 10 units per acre depending on the community
    nature.
  • Nantucket seems to appreciate a density around 4
    units per acre
  • Preserves some yard, but generally provides right
    mix
  • Would work out to 2 units per ½ acre

15
What does it look like?
  • St. Johnsbury, VT
  • 3.8 units per acre
  • Gives a yard, a garage, and a house
  • Density without overcrowding

16
Density Sizes
  • 2 acres 8 units
  • 10 acres 40 units
  • 15 acres 60 units
  • It isnt an efficient use of space to deal with
    the over 600 units of housing needed.

17
LEED for ND Criteria
  • The goal is
  • Smarter planning
  • Better use of resources
  • Better linkages
  • Incorporation of new technologies
  • Retention of historical elements
  • Retention of wetlands and habitats

18
Green Construction
19
Building Green
  • The energy required to operate the heating,
    cooling, and electrical systems ofthe typical
    American house for one year generates more than
    26,000 pounds of greenhouse gas enough to fill
    the Goodyear blimp.
  • Green buildings aren't just good for people and
    the environment but, if measured against long
    enough time frames, they make sound financial
    investments both in terms of reduced maintenance
    and operational costs as well as increased worker
    productivity. (Or resident retention.)

20
LEED for Homes
  • A distilled version of LEED for New
    Construction
  • Less stringent, more responsive
  • Less Cost
  • Same basic areas of concern

23
But it Costs too much!
  • ...a report commissioned by California's
    Sustainable Building Task Force, an upfront
    investment of two percent of construction costs
    will typically yield life cycle savings of over
    ten times the value of the intial investment.
  • However, most developers aren't interested in
    life cycle savings - it works for homeowners and
    those in it for the long haul, such as
    affordable housing developers.

25
Ways to Go Green
  • Simple changes
  • Flooring
  • Paints
  • Appliances
  • HVAC
  • Site Planning

26
Above all - Communicate
  • Communication is the key
  • Its not as hard as it sounds
  • But it might take some stepping out of your
    traditional way of operating
  • Dont make green a different layer incorporate
    it into everything.

27
LEED-ing The Way
  • 2 Clarendon Street(Berkley Street Side)

28
LEED Standard
  • Minimum LEED for Homes Certified
  • Attempt for LEED for Homes Silver
  • Project will
  • Be super-insulated energy efficient
  • Durable easy to maintain
  • Have good air quality for tenants
  • Conserve natural resources
  • A showcase for the Island

29
LEED for Homes
  • Requires use of LEED professionals and a third
    party verification process
  • Home Depot Foundation provides funding to cover
    costs of verification process
  • Will be the first LEED for Homes rated building
    on Nantucket and an early affordable housing unit
    in country rated this way

30
Infill Location
31
Compact Design
32
Site Planning
  • Building oriented for best passive solar
  • Native plantings
  • Limited driveway materials
  • Minimized turf areas
  • Shared well
  • Alternative septic system

33
Construction Details
  • Using insulated concrete forms to minimize
    material waste
  • Speeds up construction process
  • Will use waste management systems

34
Insulation Energy
  • ICFs all have high energy ratings
  • Will ensure lower fuel bills for tenants
  • Will ensure better sound quality
  • Will ensure better air quality
  • Windows will be double pane for best U value

35
Heating / Ventilation / AC
  • Unit will use radiant heat with a solar
    heating system
  • Tankless water heater will be used
  • PEX style plumbing systems (HDPE)
  • Kitchen bath will use vents to ensure good
    indoor air quality

36
Interior Materials
  • Low-Volatile Organic Compounds (VOC) paints
  • All lighting to be Energy Star rated
  • Bamboo flooring (hardwood)
  • Natural linoleum
  • Recycled PET carpeting

37
Kitchen Bath
  • Energy Star rated appliances
  • Low flow toilets and sinks
  • Aerators, tap savers, and low flow shower heads

38
Getting closer to finish!

  • Community wide green neighborhood planning
  • Implementation of all civic buildings as green
  • Cobb Hill CoHousing, VT
  • Green buildings, rural landscape
  • Orchard Gardens, MT
  • Strawbale building
