- 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 not considered to be: prime farmland, lower than 5 feet above 100 year flood plain, habitat for endangered or threatened species, within 100 ft. of wetlands, or previous public parkland.
- The site is located in close proximity to shops, entertainment venues, and other community resources for the pedestrian accessibility of occupants.
- Low-emitting and fuel-efficient vehicles have preferred parking to help minimize pollution associated with traditional automobile use.
- 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.
- The heat island effect was also reduced by using highly reflective or light colored roofing materials over the entire roof area.
- By utilizing low-flow fixtures (faucets, urinal, lavatories), potable water usage was reduced by 33% from the Energy Policy Act of 1992, thus reducing the burden on municipal water supplies.
- The 33% reduction in flush/flow fixture water use is equivalent to nearly 143,000 gallons, or over 2,374 full bathtubs per year.
- The high-efficiency toilets reduced the average gallons used per flush from 1.6 to 1.28, and the high-efficiency urinals reduced from 1 to 0.13 gallons per flush.
- When compared to the baseline case, low-flow kitchen sinks and showers alone reduced potable water usage by 43,790 gallons or 730 full bathtubs per year.
- 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 comparison against this baseline, the project exhibited a 34% 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 calculated that based on current energy rates, Pinnacle Heights I will provide a savings of over $18,900 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 with green power reduces the impact of the facility on air pollution, acid rain, smog and global climate change.
Materials & Resources
- In order to reduce the impacts resulting from the extraction and processing of virgin materials, over 11% 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.
- In order to encourage environmentally responsible forest management, the wood paneling in the lobby is certified by the Forest Stewardship Council (FSC). The FSC standard incorporates many criteria that contribute to the long-term health and integrity of forest ecosystems.
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.
- Outdoor airflow measurement devices were installed to assure that enough outdoor air is brought into multi-occupant rooms where reduced airflow could result in higher CO2levels.
- Pinnacle Heights was designed to provide ample natural daylight for occupants. 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.
- We have implemented an Integrated Pest Management Plan for the building. The goal of the plan is to reduce the exposure of building occupants and maintenance personnel to potentially hazardous chemical, biological and particle contaminants found in some pesticides, which adversely impact air quality, health, building finishes, building systems and the environment.
- 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.
