Title: New York Life Building 20 West Ninth Street


1
New York Life Building20 West Ninth Street
  • Mike Thome
  • Hoss Brown

2
New York Life Building
  • Built in 1888
  • Italian Renaissance structure with steel framing
  • 10 Story, 200,000 sq. ft.
  • Class A Office Space
  • 500 employees
  • H-shaped footprint
  • Now Utilicorp Uniteds headquarters

3
New York Life BuildingProject Scenario
  • Building idle for 5 years
  • Severe water damage led to
  • Plaster falling
  • Wood floors buckling
  • Roof leaking
  • Structure inhabited by nothing more than pigeons

4
New York Life BuildingProject Challenges
  • Aim for a 7-year payback period
  • Operate the building at 1/3 less cost than any
    Class A building in Kansas City
  • Preserve the atriums barrel-vaulted skylight and
    historical character
  • Lessen energy demands at peak times
  • Accomodate tighter conditions in the
    air-distribution system

5
New York Life BuildingOther Project Challenges
  • Upgrade to meet current building codes
  • emergency exits
  • seismic stability
  • thermal exposure
  • Add state-of-the-art mechanical and electrical
    systems to 100 year old building

6
New York Life Building System Solutions
  • Electric centrifugal chillers with ice-storage
    capabilities
  • Variable air volume (VAV) air distribution system
  • New operable energy-efficient windows
  • Added insulation to building envelope
  • New heating and hot water systems
  • 10-story infill of H footprint
  • Energy-efficient lighting and daylighting

7
New York Life BuildingNew Cooling Plant
  • Electric centrifugal chillers
  • Two 300 ton Trane machines, R-123
  • daytime chiller full-load 0.55 kW/ton efficiency,
    0.538 kW/ton efficiency at 75 load
  • ice storage chiller 0.762 kW/ton efficiency
  • Ice-storage system
  • Giant Slurpie Machine or Popsicle Machine
  • fourteen 15-foot tall, 1600 gallon insulated
    tanks
  • glycol solution cooled to 22 F at night
  • ice cools interior air during the day

8
New York Life BuildingHeating and Hot Water
  • High-efficiency gas-fired boilers
  • hot water heat to VAV boxes
  • Point-of-use hot water heaters
  • eliminated need for insulated piping and boiler
    maintenance
  • sensor-activated fixtures with preset wash times

9
New York Life BuildingLighting Improvements
  • Overhead lighting
  • T8 Fluorescent tubes
  • solid-state, low-energy, dimmable ballasts
  • Computer-controlled system
  • adjust overhead light levels according to the
    amount of daylight
  • occupancy sensors turn off lights when no one is
    present
  • Daylighting
  • ceilings slope down from windows to reflect light
    into interior
  • interior light shelves
  • light reflective colors

10
New York Life Building Other Building Load
Reductions
  • New energy-efficient windows installed
  • double-pane, low-e, insulated frames
  • custom-made operable windows to meet historical
    restoration requirements
  • Exterior masonry walls
  • R-11 fiberglass insulation added
  • New roof with R-20 insulation

11
New York Life BuildingTen-Story Infill
  • Filled in part of the H-shaped footprint with
    full height addition
  • 9,000 square feet of office space added
  • new light well protects the original skylight
  • Reduced building surface area by 15
  • Steel frame increases structural support
  • Skylight designed to evacuate smoke in an
    emergency

12
New York Life BuildingIntegrated Economics
  • All building energy systems were designed to
    reduce peak electrical demands
  • New chillers ice storage
  • purchase installation cost of 810,000
  • payback period of 10.2 years
  • Lighting system payback period of 3-4 years
  • All other building systems have 5-7 year paybacks
  • Lower payback measures
  • help to finance expensive chiller/ice storage
    work
  • help reduce overall project payback period

13
New York Life BuildingFinancing Structure
  • 35 million project, including 7 million for
    adjacent parking structure
  • Missouri Tax Incentive Program - used to finance
    75 of the renovation
  • Credit of 100 of property tax increases and up
    to 50 of sales and profits tax increases

14
New York Life BuildingProject Timeline
  • Building purchased in November 1992
  • Extensive redesign of interior and exterior to
    Class-A office space
  • Complete mechanical/electrical overhaul
  • Construction began in October 1995
  • Project complete in beginning of 1997

15
New York Life BuildingProject Results
  • Highly efficient, state-of-the-art HVAC systems
  • Utilicorp United is saving 1.4 million a year on
    utility bills from its previous headquarters
  • utility cost savings of 0.50-0.80/square foot
  • operating costs reduced from 23 to 15/square
    foot
  • overall project payback of 7 years
  • Created an extremely comfortable, modern office
    building, while retaining the character of the
    original historic building
