This paper presents a techno-economic analysis of deep energy retrofit strategies aimed at improving a typical existing home to a Net Zero Ready (NZR) level. Three distinct pathways are selected to examine the impact of modifying the mechanical system and building envelope. Each pathway is analyzed in TRNSYS for both the Montreal and Vancouver regions using a validated housing model. A techno-economic analysis methodology then combines the calculated annual energy costs with the associated material and labour costs for each option.
The analysis of the 35th AIVC- 4th TightVent- 2nd venticool Conference evaluation survey has been finalized.
The evaluation questionnaire of the 35th AIVC conference: “Ventilation and airtightness in transforming the building stock to high performance” was sent out to 124 attendees of the event. The summary report is the result of the feedback from 64 of the participants who filled in the evaluation form.
The international workshop on “Ventilation and Airtightness in Buildings : Voluntary and Regulatory Frameworks to Improve Quality and Compliance” will be held in Lund, Sweden on March 16-17, 2015. One topic of specific attention will be schemes implemented in various countries to reduce errors in ventilation and airtightness input data used in energy performance certificates and to improve the quality of the works. Discussions will be based on analyses of lessons learnt from field data.
The EU project “School Vent Cool” developed different high performance renovation strategies for school buildings. New solutions for ventilation systems, natural cooling and application of prefabricated modules were investigated.
