Sydney's Latitude East |

A Positive Latitude
This new standard for green buildings will enable the transition from voluntary guidelines and programs to enforceable criteria that can be used by local, state or federal jurisdictions. The new consensus standard was developed by ASHRAE, the U.S. Green Building Council and the Illuminating Engineering Society. It addresses site sustainability, water use, IEQ, emissions, materials and high performance operation.

Old Concepts, New Tools
This Seattle commercial office building relies on passive strategies for cooling. Advanced building simulation tools allowed the building team to design the optimal environment for natural ventilation using shading, daylighting and a center courtyard. Radiant hydronic baseboards and motorized louvers controlled by CO2 sensors provide heating and ventilation in the winter. The lack of a mechanical cooling system and forced air system contribute to the building’s performance of 37 kBtu/ft2 • yr.

Energy Use Intensity (EUI) |

Building EUIs are valuable energy performance metrics for the design, energy modeling and assessment of building energy performance. This measurement can be calculated in different ways, impacting its accuracy for comparing buildings and the energy credit given to alternative building technologies. Building use, occupant schedules, maintenance, occupancy rates and climate also affect EUIs.

Maintaining Efficiency
Even a new building that is designed for efficiency and sustainability can improve its performance through constant monitoring, adjustments, maintenance and annual evaluation of systems. A recommissioning project, annual reviews of electricity consumption and load factors, and facilities staff training have contributed to the building’s energy savings. This Boise, Idaho, building takes advantage of a municipal geothermal heating system, which uses water from hot springs to heat buildings. A rail yard formerly occupied the site, which was designated as a brownfield.

Cool Savings
The cold storage facility was the first warehouse to earn the ENERGY STAR and reduced its annual energy use by 25% over four years. Energy-efficient lighting and HVAC controls contribute to savings while participation in a demand response program reduces peak loads. The company recycles 88% of its waste and sends waste produce to a local farm where it is used as feedstock. Changes to the cooling tower water treatment method have reduced water use significantly.

Green Dividends
Two decades of efficiency and sustainability improvements have resulted in steady utility bills despite rising rates, a higher than average occupancy rate and a rising ENERGY STAR rating (96 in 2009) for this Portland, Ore., building. Motion sensors and efficient lighting in offices, stairwells and the parking garage contribute to energy savings. Low-flow fixtures reduce water use by more than 1.6 million gallons a year. Green roofs reduce storm water runoff and provide space for a putting green and an annual bocci ball tournament.
