Roddan Lodge: Vancouver’s new near zero emissions social housing facility

Past Event: August 28 @ 11:30 am – 1:30 pm


The Roddan Lodge redevelopment strives to meet both the City of Vancouver’s affordable housing priority and green building targets. Located in the Downtown Eastside, this 11-storey, 213-unit social housing project, currently under construction, will provide replacement self-contained units for the existing residents and low-end of market rental units. The new building will also contain a replacement facility for the Evelyn Saller Centre, a City of Vancouver, social service facility for low income and at-risk adults, and include a low-cost cafeteria, showers, laundry services, and a variety of social and recreational programs.

The redevelopment will be certified to a LEED Gold environmental performance standard and use high-efficiency air source heat pump systems for building heating, cooling, and domestic hot water, in order to significantly reduce its GHG emissions.

Dys architecture and MCW Consultants will discuss the project’s key energy efficiency features, as well as the outcome of an early design evaluation process comparing Passive House versus a fully electrified heating system on a more conventional envelope, as well as a comparison between air source and ground source heat pumps for space heating and domestic hot water. The rational for choosing the final design – air to water heat pumps for both space and water heating – will be outlined.

The August Decarb Lunch has been moved online to help keep our community healthy. This month only we are offering free registration! With many people working remotely, we would like to provide an opportunity for the building community to connect in a safe way, share ideas and stay inspired.
