The size of a home's windows impacts the building's energy efficiency, utilities costs, and carbon output--so smaller is better.

Buildings account for over one-third of global emissions and energy use. Meeting climate pledges will require achieving high operational energy effici…

This channel hosts video material in support of the BC Energy Step Code. The BC Energy Step Code is a new opt-in provincial standard that aims to create healthier, more efficient, and more comfortable new buildings. It does so by establishing measurable energy-efficiency requirements for new construction.

Explain to team members and clients the basic considerations for designing and building to Step 3 and beyond, including for future climate readiness, market expectations, cost, diverse building types, and future code readiness. Qualitatively assess a building’s likelihood of meeting the performance requirements of the BC Energy Step Code based on its design.

This video introduces builders to the different options they have to achieve higher performance levels when it comes to the building assemblies and their interfaces.

This module focuses firstly on building envelope details that are more commonly associated with performance issues. Viewers will then learn about quality assurance and control of the air barrier, and diagnosis and repair of the air barrier with the assistance of air tightness testing.

This module discusses correct design and construction steps for heating, cooling and ventilation systems used in Energy Step Code homes.

This module sets the groundwork for the overall design and compliance process. It shares the motivation behind this evolution towards performance-based code. It is not intended to cover design principles for the BC Energy Step Code (covered in Module 2).

This module builds on basic building science principles and applies them to the evolving/emerging enclosure design and construction practices required to meet the "envelope first" approach. This video is not intended to cover all foundational concepts and terms but offers important ideas to support.

This module presents ways in which the builder can manage the project, in cooperation with the rest of the project team and the trades, to achieve the expected performance levels.

This module discusses the different options that builders have when selecting an air barrier approach, and the important planning steps associated with a successful air barrier.

This is the 4th video in a multi-part tutorial on how to acquire daily weather data for a specific place, caclulate monthly and annual averages, and calculate heating and cooling degree days. In this video we calculate monthly heating and cooling degree days in Excel.

Minimizing thermal bridging through the building envelope is a key design aspect for achieving net-zero energy-ready (NZER) buildings. However, this can seem quite complicated for project teams, especially when much of the envelope is unknown during the early building design stage. Finding the optimal envelope solution for thermal performance that also incorporates architectural intent, cost savings, constructibility and durability is only achieved when the entire project team is engaged to collectively meet these goals. This playbook outlines good design practices for anticipating and dealing with thermal bridging in order to meet the expectations of the BC Energy [Step Code], Passive House or other NZER standards. The intent of this document is to provide guidance for design teams including developers, architects and consultants, to effectively tackle thermal bridging while meeting all project goals, not just thermal performance. 0:00 - Introduction 2:44 - Why does thermal bridging matter? 5:17 - How to set and achieve thermal bridging mitigation targets 9:06 - An example of thermal bridging mitigation for a multi-unit residential building 10:40 - Five tips to avoid thermal bridging pitfalls To access the playbook, check out 'Thermal Bridging In Net-Zero Energy-Ready Building Design' on the ZEBx.org website 'Resources' - or follow the link here: https://www.zebx.org/playbook-dealing-with-thermal-bridging-in-net-zero-energy-ready-building-design/
