First Principles to Deep Energy Retrofits in Old Buildings

Time: 11:00 AM – 12:30 PM

The masonry buildings of a hundred years ago make up the majority of our urban cores and provide significant heritage, cultural and embodied energy resources. In meeting the challenges of a net-carbon and energy-neutral building stock, replacing or demolishing all our underperforming heritage buildings is neither desirable nor advised given their resilient, robust assembly and adaptability to new uses that have proven their attractiveness over time.

This presentation is intended to dispel confusion and describe the steps one should take when facing a heritage energy retrofit. First principles to manage air leakage and moisture control—the most significant energy, heat loss and deterioration risks to heritage buildings—will be described. Three retrofit approaches, as applied to case study examples, will illustrate the concepts and impacts to energy reductions as compared to status quo conditions.

This webinar will be available with live closed captioning.

Learning Objectives

1) Understand the basics and risks of retrofitting old buildings

2) Learn the three Dos/ Don’ts for moisture control (Deflection, Drainage, Drying): Things one should never do with a heritage building.

3) Understand three retrofit approaches (maintain existing assembly; interior Insulation assembly; ventilated masonry wall retrofit / dynamic buffer zone approach).

4) Lear about case study examples demonstrating these approaches as applied to Monumental, Commercial, Residential, and Utility heritage building types and the impact to energy-use reductions.
