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. Experience gained from frontrunners shows that cost effective solutions for campuses or city districts can be achieved through a combination of energy efficiency improvements in individual buildings and advanced energy supply, distribution, and storage systems. In addition to the application of state-of-the-art technologies, this requires a clear understanding of campus or district specific energy goals, concepts for community-wide energy master planning, and business and financial models for implementations of these plans.

The project is summarizing the state-of-the-art technologies and concepts for community-wide ‘near zero energy’ masterplanning that consider both power and heating and cooling needs. The project is advancing the methodology of the ‘near zero energy community’, to enhance existing masterplanning 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 like military garrisons, universities, housing areas, and so on. The guidelines and tools to be developed within the project will support the energy masterplanning 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.

The project objectives are:


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, and

dissemination and training in participating countries designed for decision makers, planners, building owners, architects, engineers, and energy managers of public-owned and operated communities.

The planned deliverables from this project are:


a guide for near zero energy planning in building communities,

an enhanced net zero planning tool,

a book of case studies with examples of energy masterplans and near zero energy communities, and

a report summarizing the results of several realized pilot case study projects.
