Scowcroft Building Renovation (Ogden, UT)

LEED Silver Version 2.0

Sustainable Site

• Urban redevelopment area in central business area
• Preferred parking for carpooling to serve 13.33% of occupants
• Adjacency to public transportation
• 34.2% of non roof impervious areas are provided non colored concrete and shading to reduce heat island effect.
• 100% of roof meets Energy Star emissivity requirements to reduce heat islands effect. 

Water Efficiency

• 53% reduction of potable water usage for landscaping through high efficiency irrigation systems and low demand indigenous and adaptive plantings
• 23.31% water use reduction  through use of low-flow and water efficient fixtures and appliances

Energy & Atmosphere

• Optimized energy efficiency through a 20.6% energy reduction compared to ASHRAE 90.1-1999.
• Improved roof insulation, radiant base board heating, variable speed condensers
• Combines under floor air distribution with indirect/direct evaporative cooling to reduce annual energy consumption
• Improved lighting power density.
• Plan for sub metering water and energy usage
• HCFC and Halon free HVAC (heating ventilation and air conditioning) equipment 
• Green power purchased from Wind Current to meet 100% of the building electrical needs for minimum of 2 years

Materials & Resources

• Occupant recycling
• Reuse of historic building achieved 100% of the shell and 50% of the non shell
• Diverted 75.77% of construction waste through effective waste management plan
• 5.04% of total building materials by value contain recycled materials
  Indoor Environmental Quality (IEQ)
• CO2 sensors monitor to outside ambient levels and increased ventilation if exceeding thresholds
• Under floor air delivery system provides increased ventilation effectiveness in compliance with ASHRAE 129-1997
• Construction IAQ Management plan was in compliance with SMACNA guidelines. During construction, MERV 8  filters were installed at grilles and MERV 13 filters prior to occupancy
• Low emitting carpet was used
• Indoor pollutant source control
• Controllability of non perimeter temperature, ventilation and lighting systems
• Designed for thermal comfort compliance with ASHRAE 55 – 1992 for relative humidity and temperature
• Thermal comfort monitoring system installed for compliance with ASHRAE 55 – 1992 for relative humidity and temperature
• 2% day lighting  factor for 81% of occupied space for critical visual tasks achieve through introduction of 2 full height atria
• 90.6% of all occupants have direct line of sight to views for all space occupied for critical visual tasks
