  FOR HOMES Passive Design Toolkit  Passive Design Toolkit for Homes BC Hydro is a proud supporter of the Passive Design Toolkits for the City of Vancouver. We recognize that part of providing clean energy for generations is helping British Columbians build Power Smart high performance buildings. We thank you for using this Toolkit in your project, and congratulate the City of Vancouver for providing leadership in helping designers create the buildings of tomorrow in BC today. Lisa Coltart, Executive Director Power Smart and Customer Care Cover Photo: Battersby Howat Photographer: Michael BolandHand Illustrations: Matthew Roddis Urban Design Prepared by: Light House Sustainable Building Centre and Dr. Guido Wimmers.July 2009 Vancouver City Council has taken an important rst step toward our goal of becoming the greenest city in the world, as the rst jurisdiction in North America to go beyond green building codes and use architecture itself to reduce greenhouse gases (GHGs). More than half of all GHG emissions in Vancouver come from building operations, so the City has set a target that all new construction will be GHG neutral by 2030, through carbon-neutral measures in areas such as lighting and heating technologies. The Passive Design Toolkits will serve as a resource to the development industry, and as a framework for the City’s Planning department to review and update its design guidelines. Passive design elements, when evaluated in terms of relative cost and eectiveness, have been shown to reduce a building’s energy demand by as much as 50 percent.The new Toolkits will help us create a more sustainable architectural form across the city, while improving the comfort of the people who live and work in new buildings.

Introduction How to use this toolkit: This toolkit has been written to inform City sta and the design and development communities about passive design. While covering best practices, the toolkit addresses the specic needs of Vancouver and outlines a succinct denition of what ‘passive’ means for Vancouver. This toolkit can be used as a reference for best practices, and considered complementary to design guidelines and policy. The principles of passive design are not new and are, in fact, based on simple, proven concepts. Passive design refers to an approach that discourages reliance on mechanical systems for heating, cooling and lighting and instead harnesses naturally occurring phenomenon such as the power of the sun, direction of wind and other climatic eects to maintain consistent indoor temperatures and occupant comfort. By leveraging the natural environment, buildings that incorporate passive design can: help to reduce or even eliminate utility bills improve the comfort and quality of the interior environment reduce GHG emissions associated with heating, cooling, mechanical ventilation and lighting reduce the need for mechanical systems, thereby reducing the resources required to manufacture these systems, as well as the costs associated with their purchase or operation make alternative energy systems viableHomes designed using passive strategies do not have to look aesthetically dierent from those that are designed without consideration for climatic factors, but occupants of a passive home will experience greater thermal comfort while paying lower energy bills. The most rigorous European standard, PassivHaus, regulates input energy to a maximum 15 kWh / m 2 / year for heating/cooling/ventilation – about one tenth of that in a typical new 200 m 2  Canadian house, and a dierence equivalent to 300 litres of oil, 300m 3  of natural gas or 3000 kWh of electricity annually. This toolkit outlines passive design practices for low-rise wood framed construction buildings in Vancouver.
