Vancouver pre-1940 houses: a cache for old-growth forest wood

Abstract

Purpose Single-family houses in Vancouver that were built prior to 1940 are a cache of wood from British Columbia (BC) old-growth forests. The purpose of this paper is to discuss the environmental and heritage values of maintaining this finite resource, assess the current policy and regulatory efforts of the City of Vancouver to save this resource and recommend further opportunities to improve and expedite these efforts. Design/methodology/approach Using the City of Vancouver as a case study, this paper identifies effective policy practices to encourage and facilitate salvaging and reusing old wood resources. Additionally, the paper discusses the key challenges and risks that need to be addressed for these policy approaches to succeed. Findings Pre-1940 houses constitute about 40 percent of single-family houses that have been demolished in Vancouver in the past few years. The City of Vancouver enacted the Green Demolition Bylaw in 2014 requiring a minimum of 75 percent diversion of demolition waste. However, wood from these houses has been mainly chipped and recycled as biomass fuel or landscape mulch rather than reused. The result shows that regulatory enforcement along with support for infrastructure development may be crucial to protect the remainder of this valuable heritage resource. Originality/value This paper considers the environmental and heritage values of wood elements used in old houses and recommends further policy and regulatory interventions to maximize wood s…
