Kaizon Engineering offers an unmatched level of expertise on the entire building envelope. This includes extensive knowledge on roofing and waterproofing assemblies beyond what is conventionally provided by traditional facade engineers. As local councils are beginning to evaluate the complete building envelope during the consent process, the ability to deliver compliant enclosure assemblies that are integrated with the adjacent facade systems is imperative to the future of design.
Our Energy & Sustainability Consulting encompasses multiple services that allow building owners to trust their buildings are performing at the standard they should be, and gives them an understanding of improvements that can make their buildings more efficient. Some of the services we provide include energy auditing and benchmarking, building sustainability certification (LEED, Greenstar), HVAC commissioning and retro-commissioning, and condition assessment of mechanical, electrical, plumbing and fire/life safety systems.
Through our Fire Engineering capabilities, we deliver fit for purpose, cost-effective solutions for your projects. Our team of Fire Engineers is focused on delivering innovative and flexible designs to ensure your building is safe from the effects of fire, without compromising its performance or aesthetics.
Innovative facades can transform buildings into landmarks, but they are not only an aesthetic consideration. Facade design and facade consulting requires an in-depth understanding of materials, the environment, building movements, durability and sustainability, and construction methodology. We assist project teams through the consent process by performing design and construction reviews of new and existing buildings, while also preparing producer statements to document compliance with the New Zealand Building Code and specific project requirements.
Through a collaborative and integrated approach, we use our international expertise to promote an information-based design process. We help the project team select appropriate facade systems and materials and integrate them with adjacent enclosure systems to maintain performance throughout the service life of the building. Our Facade Engineers are problem solvers. They research and educate themselves to build on the knowledge they already obtain to ensure they provide the best outcomes for our clients.
Roofing and Waterproofing Consulting
Facades are not the only part of the building envelope that require expert attention. Other building enclosure systems such as plaza/terrace waterproofing, balcony deck waterproofing, vegetative roofs, exposed membrane roofs, and clad roofs must also be designed when providing an integrated building envelope. Kaizon Engineering offers a level of expertise on building enclosure assemblies beyond what is conventionally provided by traditional facade engineers.
Our understanding of international suppliers, material formulations, and product performance history allow us to evaluate individual components and determine how they will perform and interact with adjacent materials. By focusing on material properties and performance, and using an information-based collaboration process, we help the project team work through all phases of a project.
Basement Tanking Consulting
Often, the majority of attention is given to the facade on buildings, and Owners / Project Teams resign themselves to accepting a leaky basement or choosing a wet-wall approach rather than relying on a tanking membrane or DPM. Kaizon Engineering offers unique expertise and the ability to deliver the basement tanking systems that are needed to produce dry and habitable basements.
We collaborate with architects, owners, suppliers, installers, and contractors and assist them by designing and/or design peer-reviewing basement tanking assemblies. Using an information-based design process, we help the project team understand the available options and deliver a reliable and durable tanking solution.
Building Science Analysis
Building physics is an essential part of understanding how building envelopes interact with the environment and internal conditions. While New Zealand is relatively temperate, micro-climates and often humid conditions introduce challenges to deliver truly healthy living spaces. The presence of internal moisture, vapour drive, and inconsistent levels of ventilation increase the risk of condensation and biologically grown within the building envelope.
Over the last few years, the New Zealand AEC (industry) is further understanding the risk associated with traditional design strategies, and are looking for better ways to deliver energy-efficient and healthy built environments. Kaizon has the ability to utilise reliable analysis tools, such as WUFI and THERM, to help project teams evaluate insulation and ventilation strategies. The results are thermally efficient assemblies that minimise the risks that internal moisture can bring.
Quality Assurance and Field Testing
Kaizon Engineering has the resources to perform standardised tests on new materials, investigate failures, and find solutions for our clients. Our testing services support a wide variety of projects that require industry recognised, or specially tailored field-testing methods executed by trained and experienced staff. Whether testing is needed to understand new product performance, validate mock-up prototypes, quality control test installed materials, or investigate failures, qualified water testing is essential to determining field performance of facade and building enclosure systems.
Product Compliance Assessments
As the construction industry continues to grow in New Zealand, more and more overseas products are finding their place in the local market. International suppliers looking to compete with local New Zealand manufacturers must prove they can provide economical, durable, and weathertight products that are compliant with New Zealand codes and standards. Using our extensive experience with domestic standards (AS/NZS) and international standards (e.g. ASTM, AAMA, EN, etc.), Kaizon offers product assessments to provide suppliers with the engineering evaluations needed to bring in new building envelope components.
Independent Commissioning Agent Services for Green Star
All building owners should expect the best energy performance out of their newly designed buildings. With energy-efficient strategies and construction technology advancing regularly, design of the mechanical systems, building envelope, and lighting systems requires an in-depth understanding of the performance requirements, available equipment, and a wide variety of equipment control strategies. Utilising our experience in providing third-party, independent commissioning agent services per the ASHRAE guidelines, as well as a broad range of expertise in building envelope design and energy-efficient performance of mechanical and lighting systems, Kaizon Engineering is uniquely positioned to assist building owners and project teams through the design and construction process to produce buildings that are dry, comfortable, code compliant and energy-efficient.
Energy and Carbon Auditing
Kaizon Engineering facilitates all steps of the energy auditing process, establishing energy, carbon and water benchmarks based on historical consumption data, coordinating and conducting site visits to gain a thorough understanding of the building and its integrated mechanical and electrical systems, and generating a comprehensive list of appropriate Energy Conservation Measures (ECMs). Once the ECMs are identified, Kaizon performs detailed energy calculations to determine the potential energy, carbon, water and cost savings of each measure, the projected implementation costs, and the expected simple payback.
Kaizon is perfectly positioned to provide H1 compliance services. We routinely determine the building envelope R-Values and glazing U-values as part of our building envelope design and consultation services, so demonstrating the H1 Building Thermal Envelope compliance is the natural next step. Additionally, our mechanical engineer’s experience with mechanical and lighting efficiency optimization rounds out the skills needed to satisfy the H1 requirements for airflow control, hot water systems and artificial lighting. Coupling our building envelope services and mechanical systems expertise, we can guide the design to exceed the owner’s expectations, maximize the building efficiency, and demonstrate compliance with H1.
Building Energy Modelling (BEM)
BEM is an enormously helpful tool for demonstrating sustainable design, code compliance and support for green certification. Kaizon provides BEM services to assist design teams with energy efficient design, H1 compliance and carbon footprint calculations. Kaizon can generate the BEM for a project, utilizing Revit Energy Insights and Green Building Studio. Or, if a Revit model is generated by the design team, we can modify the Revit model with the pertinent building envelope thermal performance R and U values, building loads, and HVAC equipment to generate the BEM. Utilising a BEM can help the design team select their ideal WWR and building orientation early in the design, and then demonstrate H1 compliance at the end of the design.
As buildings age and their occupancies change, the HVAC equipment can start to underperform, leaving occupants uncomfortable and the utility bills high. By Retro-Commissioning (RCx) an existing building, Kaizon Engineering can functionally test the mechanical, electrical, plumbing and control systems to find and correct performance issues, as well as identify potential energy conservation measures.
MEPLS Condition Assessments
Kaizon Engineering’s Mechanical, Electrical and Plumbing (MEP) Condition Assessments provide building owners with an in-depth and technical understanding of the MEP assets contained at a property. A MEP Condition Assessment report not only delivers a comprehensive list of the main MEP equipment at a property, it also rates the current condition of each component, provides an estimated Remaining Useful Life, and provides cost estimates needed to fund immediate/short-term equipment replacements, as well as long-term upgrades.
Fire Safety is an important part of any new design. An in-efficient fire safety strategy could have significant cost and design implications. At Kaizon, we listen to your design requirements, and with you, we will develop a fit for purpose, cost-effective Fire Safety strategy for your building and provide actionable design solutions. We can also explore future-proofing options and undertake regulatory Peer Reviews of other Fire Engineers’ design.
Fire Safety Compliance
Kaizon Engineering can audit existing buildings for compliance with the current New Zealand Building Code requirements, whether that is to comfort a building owner in the level of fire safety of its building, or in anticipation of proposed upgrades.
Demonstrating a building is safe means providing its occupants have sufficient time to evacuate before the conditions inside the building become untenable. At Kaizon, we use recognised Modelling software such as NIST’s Fire Dynamic Simulator (FDS), and BRANZ’s B-RISK allowing us to provide a detailed analysis of the fire development and smoke movement within the building.
