Site Features

  • An erosion and sedimentation control plan was implemented for all project construction activities. The key objectives of the plan included: prevention of soil loss by stormwater runoff and/or wind erosion, prevention of sedimentation of storm sewers or receiving streams, and prevention of air pollution from dust and particulate matter.
  • The site is located in close proximity to community resources with pedestrian accessibility
  • Low-emitting and fuel-efficient vehicles have preferred parking to help minimize pollution associated with traditional automobile use.
  • Bicycle storage racks as well as acessible showers and changing are located on site. This promotes the use of alternative transportation, which reduces the negative impact of traditional automobiles.
  • Our project boundary is 34% vegetated open space. That’s 19,678 sf. Open space is an area consisting of grasses, and natural or introduced vegetation. This area is important because it provides habitat for vegetation and wildlife, helps with storm water infiltration, provides people in the area a connection to the outdoors, and reduces ‘heat island effect’. Heat island effect results when warmer temperatures occur in urban landscapes compared to natural areas as a result of solar energy retention on constructed surfaces.
  • A stormwater management plan was implemented to reduce the impact of development by mimicking the natural hydrologic cycle for the site. Stormwater runoff is directed to detention ponds that remove pollutants and promote ground infiltration.
  • A large portion of the property is restored habitat and open space for occupancy comfort.
  • The heat island effect was also reduced by using highly reflective or light colored roofing materials and highly reflective hardscapes.

Water Use

  • By selecting tolerant and native landscaping plants no permanent irrigation system has been installed.
  • By utilizing low-flow fixtures (faucets, urinals, and lavatories), potable water usage was reduced by more than 41% from the Energy Policy Act of 1992, thus reducing the burden on municipal water supplies.
  • The 40% reduction in flush/flow fixture water use is equivalent to nearly 62,780 gallons, or over 1046 full bathtubs per year.
  • The high-efficiency toilets reduced the average gallons used per flush from 1.6 to 1.1, and the high-efficiency urinals reduced from 1 to 0.13 gallons per flush.
  • When compared to the baseline case, lavatory faucets alone reduced potable water usage by 10,010 gallons or 166 full bathtubs per year.

Energy Use

  • To provide for continued energy and operational efficiency, all energy systems underwent fundamental commissioning. This process prevents the unnecessary use of energy while reducing Greenhouse emissions.
  • The building envelope, HVAC (Heating, Ventilation, and Air Conditioning), lighting, and other systems were designed to maximize energy performance.  In an effort to quantify the effects of each efficiency measure and the actual total expected savings, an energy simulation of the facility was performed. The baseline used for comparison was a similar building constructed to the energy efficiency standard of ASHRAE 90.1 2007 which is the same as the current minimum energy efficiency standard as required by the state of Arkansas.  In the comparison against this baseline, the project exhibited a 31% energy savings. The majority of the savings was attributed to efficient interior and exterior lighting, improved HVAC systems, and efficient hot water heating. The simulation calculation that are based on current energy rates, show Pinnacle Springs I’s design providing a savings of over $7,065.08 annually. 
  • The HVAC system of the building uses a non-HCFC refrigerant, which significantly reduces the release of harmful ozone-depleting gases.
  • Over 70% of the annual electricity usage for the first two years of building occupancy is offset by purchasing additional green power that is produced from renewable sources. Offsetting non-renewable energy purchases with green power reduces the impact of the facility on air pollution, acid rain, smog, and global climate change.

Materials & Resources

  • We created a recycling plan for recycling cardboard, paper, plastics, glass, and metals.
  • In order to reduce the impacts resulting from the extraction and processing of virgin materials, over 20% of the materials used in the construction of the building contains recycled content.
  • In order to reduce the environmental impacts resulting from transportation, and to support the use of indigenous resources, at least 20% of the materials used for Pinnacle Heights were both extracted and manufactured within 500 miles of the building.

Indoor Environmental Quality

  • In order to provide for the comfort and well-being of the occupants, minimum indoor air quality requirements were established.
  • To protect occupants from harmful second-hand smoke, smoking is prohibited within the building and within 25 feet of all entrances.
  • To provide for the comfort and well-being of construction workers and occupants, an Indoor Air Quality (IAQ) Management Plan for the construction and pre-occupancy phases was developed to maintain indoor air quality.
  • Pinnacle Springs I was designed to provide extensive views from the brewery patio and most rooms of the building. This offers tenants a connection to the outdoors, while requiring less indoor lighting.
  • Interior paints, adhesives and sealants, wall and ceiling systems, and flooring have minimal or no Volatile Organic Compound (VOC) content. VOC’s contribute to smog generation and air pollution as well as adversely affecting the well-being of building occupants, so keeping their levels minimal is essential.
  • To provide a healthier work environment, all composite wood and agrifiber products used in the construction, such as plywood, cabinetry, and doors, contained no added urea formaldehyde.
  • To support productivity and the well-being of all building occupants, the HVAC system and building envelope were designed and verified to provide a comfortable thermal environment.


  • An educational program was developed to educate the public about the sustainability principles involved in this LEED certification project. The hope is that this education program will generate greater interest in environmentally friendly construction and development.
  • Core Development, the owners of the building, has created this webpage and submitted a case study of the building to the U.S. Green Building Council. The intent is for the project to serve as a learning tool for future building owners, designers, construction teams and the general public interest in sustainable design and construction.
