What is LEED® ?The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings. LEED gives building owners and operators the tools they need to have an immediate and measurable impact on their buildings’ performance. LEED promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality. LEED provides a roadmap for measuring and documenting success for every building type and phase of a building lifecycle.

Nusantara Stone Mosaics™, can contribute to an overall strategy when applying for LEED Certification. Depending on the application and percentage of product used, LEED credits may be garnered in the following categories. Using concrete and high-reflectance white Nusantara Stone Mosaics™ rather than asphalt for at least 50 percent of sidewalks, courtyards, parking lots, driveways and access roads may reduce the Heat Island Effect. A second point can be achieved under reduced Heat Island Effect with a roof with high-reflective white Nusantara Stone Mosaics ™ tile. Using Nusantara Stone Mosaics™ covered concrete walls that are insulated to exceed minimum code requirements (about the same as minimum requirements for wood-frame walls) depending on the building type, orientation and climate can achieve Energy Savings. Since Nusantara Stone Mosaics™ incorporates a concrete sub-strate, mortar and grout it is a massive construction material that can be crushed and recycled into aggregate for road bases or construction fill, this Recyclable credit may be obtained when the building is demolished. Supplementary reclaimed material such as Nusantara Cut Stone Mosaics© which are reclaimed from quarry waste are considered Pre-consumer Recycled Content. Furthermore, using recycled Terra Cotta from de-commissioned roofing instead of extracted aggregates would qualify as post-consumer, Reuse/Recycled Content Material. Since approximately 50% of a Nusantara Stone Mosaics™ installation is in the form of mortar and grout may qualify as Regional Content if ready-mix and pre-cast plants are within 500 miles of a jobsite, and the materials used to make concrete are extracted within 500 miles. With a life expectancy of over 50 years, Nusantara Beachstone© and Cut Stone both qualify as Durable Material. Using a water based sealant on Nusantara Stone Mosaics™ will reduce the VOC (Volatile Organic Compound) off gassing significantly and qualify as a Low Emitting Material. The thermal mass of Nusantara Stone Mosaics™ covered concrete installation contributes to Indoor Environmental Quality Credit for Thermal Comfort. The amount of beach stone available for harvest is enormous. Glaciers, frequent land slides and constant tectonic activity has for millions of years created a constantly renewable supply of beach stone. Rainfall eroding and carrying stone continuously from mountains to sea shore where waves finish the shaping and polishing. This process maintains the ongoing natural supply chain. As long as there are mountains and rainfall in Indonesia, there will be a reliable supply of beach stones. Renewable Material Source
