DPR Phoenix Regional Offices Predicted Energy Use: 138,371 kwh Lucid Display showing for 2012 Showing Consumption vs. Production The Lucid Display shows the kwh s of Consumption and on-site Production for 2012. This demonstrates a Net Positive production for the DPR project of around 13,250 kwh. Approximately 10% over their energy needs.
DPR Phoenix Regional Offices Recently implemented a strategy to force upper level warm air down into main open space using big ass fans. The impact is reflected as the difference from Jan-13 to Feb-13. They should be able to do the same in Jan-14, having a significant improvement on heating demand. The gap between predicted loads and actual loads occurs between seasons when the passive hybrid evaporative cooling system, climate controlled windows and fans work in harmony to reduce typical system demands.
Sustainable Strategies Rehabilitation of a dilapidated 1972 building, using 93.7% of the existing buildings structure Day lighting provided via 82 solar tubes in roof reduces operational needs by 70%. Day lighting controls to turn lights off when adequate daylight available LED lighting utilized outside 12 BIG ASS fans help circulate air & improve occupant comfort thresholds Shower towers passively cool incoming air which is drawn naturally through a solar chimney generating 16 tons of effective cooling. Kill switch shuts down plug loads every night except refrigerator, fax and emergency lighting 250 of Green screen outside creates a microclimate for tempering outside air and shading of building spaces, reducing heat gain Low flow fixtures with waterless urinals 42% reduction in water use inside. 72% water reduction overall. 44.5% reduction in annual energy use prior to PV s EUI before PV of 28.85 kbtu/sf-yr 79kW-DC array takes projects EUI to Zero Covered parking helps reduce heat island Solar thermal DHW Within the Discovery triangle Access to Community Resources Employee fitness center with shower access Bike racks for employees Walking distance to light rail and bus transit routes 97% of all wood is FSC 32.76% recycled content 3.35% rapidly renewable content 12.88% regional content 78% of waste diverted from landfills Recycling program Green cleaning program Green educational program Low emitting interior finishes throughout Improved thermal envelope High performance glazing where necessary LUCID dashboard display keeps employees up to date on energy use
