Daybreak Corporate Center
Address: Salt Lake, Utah
Company/Developer: Kennecott Land
Project Specs: Build-to-suit
Project Type: Commercial
Square Feet: 180,000
Project History: Kennecott Land is the Master Developer of Daybreak, a 4,200-acre community in metro Salt Lake. Kennecott Land is owned by Rio Tinto, the second largest mining company in the world, with operations in the Salt Lake Valley. As part of the development, the company approached Rio Tinto to develop a building that would house all 700 of its local employees. Rio Tinto will occupy about 75% of Daybreak Corporate Center and pursued a Commercial Interiors LEED Gold Certification. This project delivered an exceptional, sustainable building under budget and on time.
Commitment to Sustainability
Daybreak Corporate Center allowed Kennecott Land to accelerate its vision of creating a sustainable community where people can live, work and recreate. Upon construction completion we held informational sessions for employees, residents and other interested parties regarding the advantages of green building. We have an informational kiosk in the lobby of Daybreak Corporate Center outlining the benefits of green building and the LEED Certification as it relates to the industry, the community and this particular project.
At Kennecott Land, every major business decision must pass a three-part litmus test: Is it sustainable environmentally, socially and economically? These “three pillars” of sustainable development, guided by strong governance, form the basis of everything we do.
- Daybreak Corporate Center is a self-funded project. No debt has been used on the project during construction, nor are there plans for debt post construction.
- No financial incentives were provided by any governmental jurisdiction, however we did apply for tax rebates associated with the significant capital investment in the photovoltaic system.
Site Sustainability/Materials Use
- The project is located about a half-mile walking distance from a proposed and funded light rail station. The Utah Transit Authority (UTA) and the building owner recognized there will be strong demand for a shuttle from the light rail stop to serve the building occupants. A contract has been drafted describing this shuttle service and the extent of the agreement.
- Bicycle storage and changing rooms with showers have been provided.
- Approximately 13 percent of the Daybreak development is built on the former site of the Kennecott Utah Copper South Jordan Evaporation Ponds. The evaporation ponds were used in mining operations. The sediment from the ponds contained elevated levels of heavy metals. In 1994, Kennecott Utah Copper began removing the sediment. Some of the sediment was consolidated, left in place and capped. When Kennecott Land decided to build the Daybreak community, a plan was put in place to remove the consolidated sediments. In 2006 Kennecott Land, the EPA and Utah Department of Environmental Quality entered into an agreement solidifying the unrestricted residential and commercial use clean up standards for the entire site.
- All post-development runoff, up to the 100-year storm event, is directed to a Storm Tech retention system. The runoff is infiltrated into the earth via two methods. The first being direct infiltrations through a gravel bottom to the system. In the second, water is directed subsurface through an approximately 75 foot deep dry well. All storm water runoff passes through a Storm Tech SC-740 Isolator Row, which is designed to remove 97 percent of Total Suspended Solids (TSS) from the runoff.
- Over 22 percent of materials by value were from recycled sources.
- Over 20 percent of materials by value were from regional sources.
- The building required a large amount of regular and fleet vehicle parking. This made it difficult to reduce the amount of hardscape. However, 100 percent of the hardscape was constructed using material with a SRI greater than 29. The sidewalks, on grade parking, parking garage slab floors, etc. were constructed using typical gray concrete with small areas of beige concrete with an equal SRI.
- The photovoltaic system consists of 112 - 190 watt solar panels for a total plate capacity of 22,400 watts. Each series array consists of 14 panels. Two series sets of 14 panels will be connected to each of 4 - 5,000 watt inverters. The solar panels are mounted on a ballasted racking system that is adjustable from a tilt of 26 to 56 degrees. The panels are adjusted four times a year to maximize power output. The installed solar panels are "Evergreen" SF 190-27-M rated at 200 watts. The rating for the subject panel is around 185 watts.
- Kennecott Land became a Rocky Mountain Power Blue Sky 100 percent Visionary partner in 2007. The company has purchased 1,949 - 100 kilowatt-hour blocks of Blue Sky renewable energy each month which equals 23,388 blocks annually. Kennecott Land is committed to remaining a 100 percent partner and will buy 100 percent of its electricity use in Blue Sky blocks a minimum of two years.
- The building has daylight throughout the entire floor area because of the incredible amount of window area. Each window has a height of 11 feet and contributes through sidelighting by both vision glazing and daylight glazing.
- Lowering overall water consumption through implementing key factors such as waterless urinals, low flow water system, Dolphin Water Treatment system, and a complete secondary water system for landscaping has resulted in an annual savings of over 67 percent in water use.
- Incorporates water-wise landscaping through four techniques: drip irrigation, drought tolerant species selection, weather-based controller efficiency, and a secondary non-potable water source.
- The landscaping plan consists exclusively of drip irrigation; which applies water directly to the soil, allowing minimal water loss due to evapotranspiration.
- The irrigation water source is a non-potable source in the form of a water feature/lake built for water re-use and recreation. This feature is fed from a canal the project client owns rights to and has been classified as onsite captured rain water.
- A weather based controller efficiency system is tied to Daybreak's centrally controlled system that is monitored via a weather station adjacent to the site. Annual water use reductions through use of this system range from three to nine percent.
