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 United’s headquarters
Building idle for 5 years Severe water damage led to: Plaster falling Wood floors buckling Roof leaking Structure inhabited by nothing more than pigeons New York Life BuildingProject Scenario
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 atrium’s barrel-vaulted skylight and historical character • Lessen energy demands at peak times • Accomodate tighter conditions in the air-distribution system
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
New York Life BuildingSystem 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
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
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
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
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
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
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
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
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
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
