For many people, the desire to own their home is a lifelong dream. Before you move in, there lies an exciting path full of challenges, decisions, and opportunities. We would like to accompany you on this journey so that you can experience a creative construction process and live in a comfortable, healthy house with low running costs.

Our Mission

Provide construction consulting services based on a unique combination of building science, building biology, and whole building simulations to improve the quality, durability, and hygrothermal efficiency of houses.

Our Values

Quality and industry-leading service are the hallmarks of HBS. We stay ahead of the curve by listening to our customers and embracing new market possibilities. Our partners trust us to provide the most advanced services and technologies available, keeping their building systems future-proof and efficient.

“Holisting Building Services & pro clima HUB working together: Marcela Brauner was the architectural designer and project manager throughout the design and construction of the pro clima HUB. Marcela combined her passion for natural building materials with her international experience to create truly unique spaces. The pro clima HUB buildings demonstrate the use of European windows, hardware, tiles, exposed timber, natural clays and organic shapes. These influences are all reflections of Marcela’s design. As well as aesthetics, Marcela paid special attention to acoustics, colours, lighting and indoor air quality to create a healthy office space and optimal learning environment.”

Dr Marcela Brauner, PhD, MSc Managing Director

Marcela is a distinguished building science and building biology authority with a PhD in hygrothermal modelling and over 25 years of cross-disciplinary experience in the construction industry. As the Managing Director of Holistic Building Services Limited, she provides strategic energy and building envelope consultancy for architects, developers, and homeowners across New Zealand and Australia.

Marcela specializes in moisture-mitigation strategies, building biology, and the integration of natural, non-toxic materials. She is a leading expert in whole-building hygrothermal modelling, delivering precise design advisory and thermal simulations tailored to meet New Zealand Building Code H1 Energy Efficiency requirements via the H1/VM1 Verification Method.

Experience, Knowledge, Integrity

Our Expertise – Your Vision

From initial consultations and material specifications to integrated whole building hygrothermal and energy simulations, we provide the expert analysis required for high-performance building systems. We offer our proven technical expertise to stakeholders committed to health and sustainability in new construction, renovation, and the modern workspace.

Business Prospects

HBS is the optimal business partner if you are looking for:
  • Elevating Construction Quality: We implement rigorous standards to ensure the highest level of structural and functional integrity.
  • Strategic Benefits of Early Project Engagement:
    • Comprehensive Risk Mitigation: We identify and eliminate design defects—including functional, structural, and technological flaws—while conducting precision assessments for interstitial condensation and mold growth.
    • Holistic Design Optimization: We facilitate interdisciplinary collaboration to maximize hygrothermal performance, significantly reducing environmental impact and improving occupant health.
    • Capital Expenditure (CAPEX) Reduction: Our rigorous design assessments and whole-building simulations optimize material use and prevent costly onsite errors through regular construction oversight.
    • Operational Efficiency (OPEX): We deliver long-term savings by minimizing heating and cooling demands and reducing lifecycle maintenance requirements.
    • End-to-End Lifecycle Support: We provide dedicated technical consultancy throughout every phase of the project, from initial concept to final occupancy.
