Spring @ 8th, Phase 1

Spring @ 8th is the new corporate headquarters for NCR, the global leader in consumer transaction technologies. NCR’s software, hardware and portfolio of services make nearly 550 million transactions possible every day. In the Spring of 2015, NCR approached Cousins Properties to develop a new class of office building on a site in close proximity to Technology Square in Midtown Atlanta. Cousins Properties challenged Integral Consulting Engineering with designing building systems that balance water- and energy-efficiency with resilience and cost.

Site Water Strategy
Project goals include a 60% reduction in base building potable water demand through the harvesting, treatment and reuse of contaminated groundwater, rainwater and mechanical equipment condensate. Groundwater will be harvested treated and reused (~7,200 gallons/day; 7 days/week). The project prediction is to offset 100% of potable water demand for flush fixtures (~6,000 gallons/day; 5.5 days/week), excess groundwater (~17,000 gallons/week) predicted to cover 100% of site irrigation demand. Stormwater and condensate harvesting, treatment and reuse (~1,400,000 gallons/year) predicted to offset 30% of the potable water demand for cooling tower make-up. Project employs low flush and flow fixtures: toilets (1.28gpf), urinals (0.125gpf), showers (1.5gpm), lavatories (0.5gpm) and sinks (1.5gpm).

Site Energy Strategy
Other project goals are a 25% energy and energy cost reduction (vs. ASHRAE 90.1-2007) and an Energy Use Index (EUI) target of 45 kBtu/sf/yr. Targeted EUI represents a 50% reduction relative to similar buildings in the Commercial Building Energy Consumption Survey (national database used by EnergyStar). Energy and energy cost reduction is achieved, in part, through high-performance glazing, an efficient chilled water plant, dedicated outdoor air systems for energy recovery and dehumidification, low-energy lighting design (0.7 Watts/SF) with occupancy sensor controls and a building management system with advanced metering, fault detection and analytics. 10,000 SF (~160kW) solar PV array over open-air portion of parking deck predicted to generate 250,000 kWh of renewable power annually.

In addition to its water and energy efficiency goals, Spring @ 8th incorporates a Distributed Antenna System and redundant fiber feeds to facilitate Wifi and cellular connectivity throughout the building. The targeted network speed is 1Gb/sec from multiple providers.
