11:00am - 12:00pm Speakers: David Waters and Robyn Gibbard | Metro Performance Glass
Synopsis: Managing Solar Gain: The Role of High Performance Glazing in Thermal Comfort
In a typical New Zealand home, glazing represents approximately 8% of the building envelope, yet it can contribute five to eight times that in heat gain and heat loss. When solar gain is not well managed, buildings are more prone to overheating, increasing the need for artificial cooling to maintain occupant comfort.
Glass is the only building material that allows both light and heat to pass through it, making glazing a critical factor in overall thermal performance. Under New Zealand conditions, solar radiation can be effectively managed through informed design decisions, supported by appropriate glazing selection and performance modelling.
This CPD session examines the role of Metro Low E high performance glazing can lower heat gain by up to 71% and reduce heat loss by up to 61% compared to standard double glazing and highlight that the key to product selection is all about balance.
Key Learning Outcomes:
Identify the primary causes of overheating in New Zealand buildings and the role glazing plays in thermal performance
Understand how thermal and solar modelling can be used to assess and mitigate overheating risk during the early design stages
Evaluate high performance glazing options to help reduce the risk of overheating while maintaining comfort and natural light.

Speaker:
Jason Quinn is an ex NASA engineer who was taken aback by the poor housing quality when he moved to New Zealand. He has a passion for improving home performance, a motivation sparked by his personal experience of renovating his own home. His business ‘’Sustainable Engineering’’ leverages his extensive knowledge and specific modelling data to assist the design community toward better built-in performance when designing homes.
Learning Outcomes:
Understanding the effects glass selection has on thermal comfort and solar heat gain, in relation to building types and climate zones – through predictive thermal modelling.
Knowledge of the performance difference between double and triple glazing with coated glass incorporated into the units.
Analysis of the impact on the homeowner when specifying Low E coating onto surface 2 or 3 of a double-glazed unit.
Is glass selection the rocket science of building today?

Windows remain a critical area for addressing heat loss or gain in our buildings, with glass being the largest contributing factor. Recent advancements in glass technology and thermal coatings, along with various types of insulated glass units, have transformed the landscape. What do the latest numbers tell us about the impact of these changes? How can we continue to reduce carbon emissions and lower both environmental and financial costs through innovative solutions?
Join us to hear from our highly qualified guest speakers who will share their targeted research and insights into these rapidly evolving topics.
Discover the data, solutions, and strategies that are shaping the future of energy-efficient building design.
