Methodology: The ZERO-PLUS approach

Morna Isaac, Shabtai Isaac

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


The ZERO-PLUS approach is a modular and collaborative solution for the design and construction of new residential net-zero energy settlements. It is composed of a method and accompanying tools that address the barriers to successful construction of net-zero energy settlements. The ZERO-PLUS approach brings together technology suppliers, energy efficiency and renewable energy experts, and developers who collaborate from the earliest stages of project conception. The approach covers three phases: design, construction, and occupancy. At the design phase, an optimization process is performed, accompanied by the selection of suitable technologies. This ensures that the project’s renewable energy and energy savings targets are achieved at the lowest possible cost. During construction, tools are provided to ensure that the as-built energy and financial performance conforms to the design. During occupancy, a WebGIS platform provides all the information needed for optimal, cost-effective maintenance of the settlement. The approach is technology-neutral.
