CoV Green Buildings Policy for Rezonings Amended November 29, 2016
• “This Policy is effective immediately and shall be mandatory for all Rezoning Applications received on or after May 1, 2017, with exceptions permitted at the discretion of the Director of Planning.” • All Rezonings must meet the following requirements of either: A. Near Zero Emissions Buildings or B. Low Emissions Green Buildings
CoV Green Buildings Policy for Rezonings • REQUIREMENTS
A. Near Zero Emissions Buildings Projects shall be designed to meet Passive House requirements and apply for certification, or to an alternate near zero emissions building standard, such as the International Living Future Institute’s Net Zero Energy Building Certification, as deemed suitable by the Director of Sustainability. OR A. Low Emissions Green Buildings

CoV Green Buildings Policy for Rezonings B. Low Emissions Green Buildings 1. LEED Gold – Building Design and Construction All projects – with the exception of residential buildings (at least 50% of gross floor area is residential space) – shall register with the CaGBC and be designed to achieve LEED Gold certification for BD+C, or an alternate holistic green building rating system. Where a project has multiple buildings, each building shall be evaluated separately. AND 2. Performance Limits All buildings shall meet or exceed performance limits according to their building type summarized in the tables below, as modelled according to the City of Vancouver Energy Modeling Guidelines. The Energy Modeling Guidelines set standard assumptions and requirements for energy models when assessing compliance with the limits, including accounting for thermal bridging, consideration of summertime thermal comfort, and the treatment of mixed-use buildings.
