Welcome to the pro clima Podcast, where we're dedicated to fostering better building practices in New Zealand.

Our mission is to

inspire and educate people to create healthy, durable and energy-efficient buildings
to live, learn, work and play in — now, and for generations to come.

Throughout this podcast series, we will talk to architects, builders and homeowners about various aspects of building design, construction techniques, and sustainable building. Here's what you can expect from our episodes:

Expert Interviews: We'll invite architects, engineers, builders, and other industry professionals to share their insights and experiences on designing and constructing high-performance buildings. From building to the code, through the Passive House design practices, to cutting-edge construction materials and innovative construction techniques - we'll cover it all.

Case Studies: We'll showcase New Zealand buildings that embody the principles of health, durability, and energy efficiency.

Homeowner Perspectives: We'll also hear firsthand from homeowners who have embarked on their own building journeys. They'll share their motivations, experiences and lessons learned.

Emerging Trends and Technologies: We'll explore the latest trends and advancements in effective and sustainable building practices. Discover new technologies and trends that are shaping the future of construction in New Zealand.

Audience Engagement: We value your input! We encourage listeners to share their questions, suggestions, and topics of interest for future pro clima Podcast episodes. Your feedback will give us direction and ensure that we're addressing the most pressing issues facing the New Zealand building community. If there are topics you would like us to talk about in our future podcasts or have feedback, contact us.

Join us on this journey towards better building practices in New Zealand.

Guest: Natasha Cockerell, Director of the Respond Architects

An architect with talent and focus, Natasha is a rarity within the industry – an ‘all-rounder’ combining a capability for sensitive design with an advanced knowledge of building science and technical detailing.

Natasha believes that communication is the key to a successful project and prides herself on building relationships with clients, stakeholders, consultants and contractors to ensure great outcomes.

She is involved in a variety of residential, commercial and educational projects, and although she relishes the challenge of large, complex projects (such as the Takapuna Main Block Development project which is currently under construction), she also appreciates the chance to work with Schools on a variety of unique projects of varying sizes. Natasha is passionate about creating great spaces for learning, and her track record of over 11 years working on Ministry of Education projects reflects this. She's also a member of MoE's Weathertightness Review Panel and the Passive House Institute NZ (PHINZ) Board.


“We accept a lot just because we don’t know any different.”

Podcast topic: In the second episode of pro clima podcast, Natasha explains how seeing her relatives work in construction sparked her interest in architecture, which she sees as a combination of art and science. From her experiences with leaky buildings to addressing challenges in the industry, we discuss the current state of the New Zealand construction sector, focusing on economic difficulties and the urgent need to address carbon emissions. Looking ahead, she advocates for a shift towards sustainable, energy-efficient building practices, emphasizing holistic approaches to building performance and the importance of homeowner awareness in selecting architects. Natasha champions prioritizing simplicity, efficiency, and comfort in building design, highlighting the potential of energy modelling to deliver better outcomes while saving costs.
