  4. 4. OPERATION [“Being there”] Your organization is working towards a sustainable future. You are striving for a clear understanding of your current position and to set goals to support your global vision. FACILITY MANAGEMENT Intep supports you in defining portfolio or project specific operation planning by defining FM structure, processes appropriate to the performance targets set. With new projects ideally accompanying the design process. GLOBAL IMPACT [“Where are we and where do we go?”] Your organization is working towards a sustainable future. You are striving for a clear understanding of your current position and to set goals to support your global vision. STRATEGIC PLANNING Intep creates framework plans based on the analysis of your current position and a global vision for resource and energy efficiency for your build environment. CITY/CAMPUS [“How do we get there?”] Your vision is to implement sustainable strategy for your built environments like the 2000-Watt Society. MASTER PLANNING Intep develops appropriate building performance standards and applying sustainability frame work to specific project developments including feasibility. BUILDINGS [“Going there”] You are implementing buildings projects based on global leading performance targets and design standards like Passive House or Minergie. IMPLEMENTING Intep offers project steering to you directing your design team, or comprehensive, integrated design services to execute your project to the highest standards.

  13. 13. “A rigorous, voluntary building energy standard focusing on highest energy efficiency and quality of life at low operating cost.” The Passive House Standard is the most rigorous building energy standard in the world. Consultants, projects or building components that have obtained the right to carry the logo have committed themselves to design excellence and the Passive House energy performance criteria.
