SS p1 Construction Activity Pollution Prevention

  Prevent soil from geo-thermal well digging on south side flowing into storm sewers

• • • •


SS c1 Site Selection

  Reduces impact from location of building


SS c2 Development Density & Community Connectivity

  Opt 1 - Is a previously developed site but not 60,000 sf per acre

  Opt 2 - Is a previously developed site but not 10 units per acre or enough Basic Services within ½ mile

  Square is 1 mile per side


SS c3 Brownfield Redevelopment

  Site isn’t documented as contaminated by federal, state, local or voluntary program


SS c4.1 Alternative Transportation – Public Transportation Access

  No bus stops within ¼ mile

  Picture is ½ mile per side

  The Middleton Ave. is so wide because it used to have a streetcar line down the middle of it.


SS c4.2 Alternative Transportation – Bicycle Storage and Changing Rooms

  2 FTE (Full Time Equivalent) Occupants

 Not a commercial or institutional building requiring racks for 5% of peak users and showers for 0.5% FTE

SS c5.1 Site Development – Protect or Restore Habitat

  Opt 1 Greenfield site – limit disturbance: 40’ bldg, 25’ permeable drive, 15’ roadway, 10’ patios

  Opt 2 Previously developed site – 50% to be planted with native or adaptive vegetation

  Exemplary Performance 75% of site area excluding building footprint


SS c5.2 Site Development – Maximize Open Space

  Opt 1 Exceed local zoning requirement by 25% with vegetated open space

  Opt 2 If no zoning requirements - Provide vegetated open space equal to footprint

  Opt 3 – No zoning requirement for open space – provide 20% vegetated open space

  Exemplary Performance for open space 2x the building footprint


SS c6.1 Stormwater Design– Quantity Control

  Opt 1 – Existing imperviousness is less than or equal 50% (one-year, 24-hour design storm – about 2.75” for Maryland). 1” of rain would require 890 gal. storage for the 1500 sf roof. Install 8 rain barrels.

  Opt 2 – Reduce existing, imperviousness greater than 50%, volume stormwater runoff by 25% (two-year, 24-hour design storm – about 3.5” for Maryland)


SS c6.2 Stormwater Design– Quality Control

  Cincinnati receives 40” of rain per year.

  To meet this credit we’ll demonstrate that the site can absorb 1” of rainfall. The site can but the roof’s 900 gallons need to be treated.

  East rain barrels would need to increase to 400 gallons

 West side would need to add a rain garden

Rain garden


SS c7.1 Heat Island Effect – Non-Roof

  Opt 1 – At least 50% of site has shade (paver drive doesn’t count because it isn’t at least 50%pervious)

  Opt 2 – Less than 50% of parking spaces are under cover (None are)


SS c7.1 Heat Island Effect – Roof

  Opt 1 – Roofing materials need SRI of 78 for 75% of roof. Current flat roof’s SRI is 70. Would need to paint it with a 78 SRI material.

  Opt 2 – Vegetated roof for 50% of roof area

  Opt 3 – 1500 sf = 60 4sf green roof trays for ballast and paint 765 sf with SRI material 78.


SS c8 Light Pollution Reduction

  For Interior Lighting – Some interior lighting’s angle of maximum candela exits out through the windows. Install motion sensors to automatically turn off lights.

  For Exterior Lighting – project is 80% below 1.0 w/sf for walkways. Building façade exterior lights are 1500w, above 100w (500 sf * 0.2 w/sf)

WE 3.1 – Water Use Reduction 20% Reduction


WE 3.2 – Water Use Reduction 30% Reduction

EA p2 – Minimum Energy Performance

  ASHRAE/IESNA 90.1-2004 Doesn’t apply to low rise residential buildings, single family houses, multi-family structures of three habitable stories or fewer above grade, manufactured housing or buildings that do not use either electricity or fossil fuel.

  Min/Existing Above roof R15/40 Walls R13/10 Slab floor R7.5/0


EA p2 – Minimum Energy Performance

  Walls are 35% glazing requiring Solar heat Gain Coefficients of:

  North .36

  All .25

  The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight. The SHGC is the fraction of the heat from the sun that enters through a window. SHGC is expressed as a number between 0 and 1. The lower a window's SHGC, the less solar heat it transmits.

  The Boulter House project can’t comply with this prerequisite without adding additional floor and wall insulation


EA p3 – Fundamental Refrigerant Management

  Replace or retrofit the CFC-based refrigerants in existing base building HVAC&R


EA c1 – Optimize Energy Performance



  Dual-Pane Metal Frame tinted low-E glass doors and windows are required with thermal break

  Ambient Lighting Power Density should average .898 w/sf   Boulter House living

room is 18’ x 28’ = 504 sf

  28 40w showcase lamps = 1120 watts

 Need to replace with LED showcase lamps



  Carport glass needs to be replaced with Dual-Pane Metal Frame tinted low-E glass doors and windows with thermal break. May use NanaWall.

  21% Improvement over EA p1 is needed for LEED Platinum 52 Points



  Installing NanaWall on both sides of carport breeze way will allow the space to again be used as designed by FLW Copyright 2009 Chuck Lohre
