What Does an ESD Consultant Look for in Building Materials?

When specifying materials for a building project, Environmental Sustainable Design consultants are not only looking at how a product performs on day one. They are looking at the bigger picture.

How long will it last?

How often will it need to be maintained?

What is it made from?

How does it affect indoor air quality?

What happens over the full life of the building?

For ESD consultants, building materials are assessed through a broader sustainability lens. A product may claim to be “eco-friendly”, but its real value depends on performance, durability, health, maintenance requirements and environmental impact over time.

This is especially important when specifying coatings, paints and façade finishes. These materials are applied across large surface areas and play a major role in how a building performs, ages and is maintained.

What Is an ESD Consultant?

ESD stands for Environmentally Sustainable Design.

An ESD consultant is a sustainability specialist who helps project teams improve the environmental performance of a building. Their role is to look beyond the visual outcome and assess how a building uses resources, performs over time, supports occupant wellbeing and reduces environmental impact.

ESD consultants often work alongside architects, developers, builders, engineers, interior designers and specifiers. They may be involved from the early design stages through to documentation, certification and construction.

Their advice can influence decisions around energy efficiency, thermal comfort, water use, material selection, embodied carbon, indoor air quality, waste reduction, maintenance requirements and long-term building performance.

In simple terms, an ESD consultant helps make sure a building is not only well designed, but more responsible, resilient and efficient over its lifetime.

Who Uses ESD Consultants?

ESD consultants are used across a wide range of building projects in Australia, particularly where sustainability outcomes, compliance requirements or long-term performance targets are important.

They are commonly engaged by architects, developers, builders, project managers, government bodies, commercial property owners, education providers, healthcare organisations, aged care providers, interior designers and specifiers.

Architects may work with ESD consultants to strengthen sustainable design strategies, material choices and environmental performance goals. Developers may engage them to improve the value, marketability and long-term performance of a project. Builders may rely on their guidance when selecting compliant, practical and sustainable materials.

Government bodies and councils often use ESD consultants for public buildings, community infrastructure and climate-responsive developments. Commercial property owners may engage them to reduce operating costs, improve asset performance and meet sustainability targets. In education, healthcare and aged care settings, their input can be especially important because indoor air quality, durability and occupant wellbeing are closely linked to the performance of the building.

While ESD consultants are often associated with large commercial, civic and multi-residential developments, their role is increasingly relevant across almost every building type. From apartments, schools and workplaces to hotels, homes, health facilities and heritage projects, better material choices can have a major impact on how a building performs over time.

Why ESD Consultants Are Important in Australia

ESD consultants play an important role in the Australian building industry because our buildings are being asked to do more.

They need to respond to a demanding climate, meet higher sustainability expectations, reduce environmental impact and perform well for the people who use them every day.

Australia’s built environment faces intense UV exposure, heat, humidity, coastal conditions, rising energy demands, urban heat issues and increasing pressure to reduce carbon emissions. At the same time, clients, councils, developers and communities are placing greater value on buildings that are healthier, more durable and more sustainable.

This is where ESD consultants add real value.

They help project teams make better decisions earlier, before poor material choices become expensive maintenance issues or long-term performance problems.

Their work can help reduce unnecessary material waste, frequent replacement and repainting cycles, poor indoor air quality, moisture-related issues, operational energy demands, embodied carbon impacts, long-term maintenance costs and short-term thinking in material specification.

For coatings and finishes, this is especially important. Paint is often treated as a decorative layer, but for an ESD consultant, it is part of the broader building system. The right coating can influence durability, breathability, indoor air quality, maintenance cycles, façade performance and whole-of-life sustainability.

That is why material selection matters so much.

Looking Beyond the Product Label

Sustainable building design is no longer just about choosing products with green marketing claims. ESD consultants look for evidence.

They want to understand the full material story, including:

• What the product is made from

• How it performs over time

• Whether it supports building health

• How often it needs repainting or replacement

• Whether it contributes to lower maintenance cycles

• How it affects indoor air quality

• Whether it has transparent environmental documentation

• How it contributes to long-term building performance

A low-impact material should not simply perform well at the point of installation. It should continue to perform for years, ideally decades, without creating unnecessary maintenance, waste or replacement cycles.

Durability and Long-Term Performance

Durability is one of the most important considerations for ESD consultants.

A material that needs frequent recoating, repairing or replacing creates more than a maintenance issue. It creates additional resource use, labour, waste, transport emissions and cost across the life of the building.

This is where long-life coatings can make a significant difference.

Conventional acrylic paints typically form a plastic film over the surface. Over time, that film can weather, peel, trap moisture or require repainting. In contrast, KEIM mineral silicate paints work differently. Rather than sitting on the surface as a plastic layer, they chemically bond with mineral substrates through a process known as silicification.

This creates an extremely durable finish that becomes part of the substrate, rather than a coating that simply rests on top.

For ESD consultants, this matters because longer product life can support reduced repainting cycles, lower maintenance requirements, less material waste, reduced lifecycle impact, better long-term value for building owners and more resilient façade and interior finishes.

A coating that lasts longer is not only a performance decision. It is a sustainability decision.

Embodied Carbon and Lifecycle Impact

Embodied carbon is a key focus in sustainable building design. It refers to the carbon emissions associated with materials across their lifecycle, including raw material extraction, manufacturing, transport, installation, maintenance and end-of-life considerations.

While high-impact structural materials often receive the most attention, finishes and coatings should not be overlooked. Paint may seem like a small part of the overall building system, but it is applied repeatedly across large areas and often replaced many times over a building’s life.

That is why ESD consultants look beyond the initial litre of paint.

They consider the full lifecycle impact.

A coating that needs to be repainted every few years may carry a much higher long-term environmental cost than one that performs for decades. Each repainting cycle requires more product, more packaging, more transport, more labour and more waste.

KEIM mineral paints are designed for longevity. Their mineral composition, colour stability and substrate-bonding technology help reduce the need for frequent recoating. This can contribute to lower maintenance-related emissions over the life of the building.

For projects pursuing stronger sustainability outcomes, long-life material choices can help reduce the hidden environmental impact of ongoing maintenance.

Maintenance and Whole-of-Life Cost

ESD consultants often think in terms of whole-of-life performance.

This means looking beyond the upfront purchase price and assessing the true cost of a product over time. A cheaper coating may look attractive during construction, but if it requires frequent repainting, cleaning or repair, it may become more expensive and less sustainable in the long run.

Maintenance matters because it affects operational costs, building disruption, access equipment requirements, labour, transport, waste generation, material consumption, long-term appearance and asset value.

For façades, this is particularly important. Exterior coatings are exposed to UV, rain, pollution, heat and substrate movement. If the finish breaks down quickly, the cost and impact of maintenance can be significant.

KEIM mineral silicate paints are known for their exceptional durability and colour stability. Because they use inorganic mineral pigments, the colour is highly resistant to fading. The finish remains mineral, matte and lightfast, supporting long-term visual performance without relying on a plastic film.

For ESD consultants, reduced maintenance is not just a convenience. It is part of the environmental equation.

Health, Indoor Air Quality and Low-Tox Specification

Material health is another major consideration in sustainable design.

ESD consultants look closely at how products affect people, particularly in interior environments. Paints, coatings, adhesives and sealants can contribute to indoor air quality issues if they contain volatile organic compounds, solvents or other harmful additives.

For schools, healthcare environments, workplaces, homes, hospitality spaces and aged care settings, low-tox materials can play an important role in creating healthier interiors.

KEIM mineral interior paints offer a different approach to conventional plastic-based paints. Products such as KEIM Innostar are zero VOC and made with a mineral formulation that does not rely on solvents, plasticisers or added biocides.

This makes them a strong consideration for projects where indoor air quality, occupant wellbeing and low-emission materials are a priority.

For ESD consultants, healthier material choices can support better indoor air quality, reduced exposure to harmful emissions, low-tox interior environments, occupant wellbeing and more considered specification outcomes.

A sustainable building should not only reduce environmental harm. It should also support the people who live, work and spend time inside it.

Breathability and Moisture Management

Moisture is one of the most common causes of building performance issues.

When coatings prevent walls from breathing, moisture can become trapped within the substrate.

This can contribute to blistering, peeling, mould risk, material degradation and ongoing maintenance problems. ESD consultants understand that moisture management is closely linked to durability, health and long-term performance.

KEIM mineral silicate paints are highly vapour permeable, allowing moisture vapour to pass through the coating rather than becoming trapped beneath a plastic film. This supports the natural drying ability of mineral substrates and can help reduce issues associated with trapped moisture.

For breathable building systems, this is a major advantage.

Vapour permeability can contribute to reduced risk of trapped moisture, improved coating longevity, lower likelihood of peeling or blistering, better substrate performance, reduced mould risk in moisture-prone environments and healthier building outcomes.

For ESD consultants, breathability is not a technical bonus. It can be central to how a material performs over time.

Transparency and Environmental Credentials

ESD consultants are increasingly looking for products with transparent documentation and credible environmental information.

This may include Environmental Product Declarations, lifecycle assessment data, third-party certifications, material health information, VOC documentation, fire and compliance data, durability testing and warranty information.

These documents help consultants make informed decisions and support the broader sustainability targets of a project.

KEIM products are supported by a strong environmental profile, including Cradle to Cradle Certified® products and Environmental Product Declarations for many systems. This level of transparency gives specifiers greater confidence when assessing KEIM within sustainable building projects.

For consultants, this is important because sustainability claims need to be backed by evidence.

Material Composition and Plastic-Free Thinking

Another area of growing interest is material composition.

Many conventional paints are based on acrylic polymers, which are essentially plastic binders. These coatings form a plastic film over the surface. While common, this approach can raise questions around breathability, longevity, microplastic pollution and end-of-life impact.

KEIM mineral paints are different.

They are not acrylic paints. They are mineral silicate paints made with potassium silicate or sol-silicate binders, mineral fillers and inorganic pigments. Instead of forming a plastic film, they bond with mineral substrates.

This makes them a compelling choice for ESD consultants looking for coating systems that align more closely with mineral construction materials, long-term durability and reduced reliance on plastic-based finishes.

Choosing paint is not only about colour. It is a material decision.

Exterior Performance in Australian Conditions

Australian buildings are exposed to intense UV, heat, rain, humidity, coastal conditions and major temperature variation.

For ESD consultants, exterior material performance must be assessed in context. A coating that performs well in mild conditions may not necessarily provide the same durability in harsher climates.

KEIM mineral silicate paints are well suited to demanding façade environments because they are UV-stable, vapour permeable, mineral-based and highly durable. Their inorganic pigments deliver long-term colour stability, helping buildings maintain their appearance without frequent repainting.

In warmer climates, KEIM also offers specialised systems such as Soldalit-Coolit, which uses infrared-reflective pigment technology to help reduce heat absorption on façades, even in darker colours.

This can support broader goals around thermal performance, façade longevity and urban heat island mitigation.

Why KEIM Is the Dream Product Range for ESD Consultants

For ESD consultants, the ideal building material is not just one that looks sustainable on paper. It needs to perform in the real world.

It needs to be durable, low maintenance, healthy for occupants, transparent in its environmental credentials and suited to the long-term demands of the building.

That is exactly where KEIM mineral paints stand apart.

KEIM offers a product range that aligns closely with the priorities ESD consultants consider when reviewing building materials. Its mineral silicate paints are designed for long-term durability, exceptional colour stability, vapour permeability, low-tox interiors and reduced reliance on plastic-based coating systems.

Unlike conventional acrylic paints, KEIM mineral paints do not form a plastic film over the surface. They work with mineral substrates through silicification, creating a durable bond that becomes part of the building fabric. This supports longer repaint cycles, reduced maintenance and better whole-of-life performance.

For interiors, KEIM’s zero VOC mineral paint options support healthier indoor environments. For exteriors, KEIM’s breathable, UV-stable and highly durable façade systems help buildings withstand harsh Australian conditions while maintaining their appearance over time.

For ESD consultants, that combination is powerful.

KEIM supports many of the material priorities that matter most in sustainable specification:

• Long-term durability

• Reduced maintenance

• Lower lifecycle impact

• Excellent colour stability

• Vapour permeability

• Zero VOC interior options

• Mineral-based composition

• Plastic-free paint technology

• Transparent environmental documentation

• Proven façade performance

• Healthier indoor environments

This makes KEIM more than a paint brand. It is a material solution for sustainable architecture.

For architects, developers, builders and ESD consultants looking for coatings that support durability, health, lower maintenance and long-term environmental performance, KEIM is the dream product range.

Because the most sustainable coating is not simply the one with the strongest claim.

It is the one that lasts, breathes, performs and supports the building for decades.
