About Annex 73

Until recently, most planners of public communities - for example military and university campuses - have addressed energy systems for new facilities on an individual building basis without consideration of energy sources, renewables, storage, or future energy generation needs. This situation in planning and execution of energy-related projects does not support attainment of current energy reduction goals or the minimization of costs for providing energy security.

The project is summarizing the state-of-the-art technologies and concepts for community-wide ‘near zero energy’ master-planning that consider both power and heating and cooling needs. The project is advancing the methodology of the ‘near zero energy community’, to enhance existing master-planning strategies and modelling tools, and expand their application by adding standardized country-specific building data on specific building types, and information on advanced energy efficiency technologies and on their performance and cost characteristics.

The scope of the project is to develop the methodology and the decision-making process that will be transferred into computer-based modelling tools for achieving near zero energy in public communities such as military garrisons, universities, housing areas, and so on. The guidelines and tools to be developed within the project will support the energy master-planning process and will address technical, economic, social, financial, and business components presented in the way that is easy to understand and execute. The outcomes will be applicable to public communities in the participating countries.

Project Objectives

  • establishing energy goals and a database of energy utilization indices for representative buildings and building communities
  • developing a catalogue of building models, including mixed-use buildings, applicable to national public and private communities and military garrisons
  • collecting and analyzing best practices of energy master planning with the goal of establishing a step-by-step energy master planning process to be executed using the computerized tool
  • collecting information on the architecture of advanced central energy systems, analyzing their applicability to different building communities’ needs and constraints, and evaluating these scenarios from the technical, economic, financial, and business perspective
  • dissemination and training in participating countries designed for decision makers, planners, building owners, architects, engineers, and energy managers of public-owned and operated communities .
