How Does Sustainable Engineering Design Improve Long-Term Building Efficiency?

‘Sustainable’ has gained a reputation as a buzzword over the years, but as time marches on, it is becoming increasingly clear how important this principle is in the creation of all long-term developments. As engineers, sustainable engineering design is a relatively new discipline in the industry, but it is quickly rising in importance for both developers and consultants.

This is down to a variety of reasons, including a greater focus on living and building greener, and more tangible governmental pressure to adhere to emerging sustainable engineering guidelines.

The crux of the matter is that sustainability engineering supports future-proofed buildings. Through the lens of helping you create developments that will go the distance (with minimal future alterations required), here is our breakdown of how sustainable engineering design improves the long-term efficiency of your building.

The 4 Principles of Sustainable Engineering Design

Because of its evolving nature, sustainable engineering is still understood as a spectrum. Generally speaking, it’s not just about adding some solar panels to the roof and moving on (though that is one aspect of your building’s engineering that you could make more sustainable).

Rather, four principles lie beneath the umbrella of a holistic approach to sustainable engineering design. These principles consider the entire lifecycle of the building and – most importantly – its impact on the environment now and into the future.

The four principles are:

1. Passive design integration, which utilises the natural design elements of the building (i.e. orientation, thermal mass, natural ventilation) to minimise the need for an overactive HVAC system.
2. System optimisation, which ensures all mechanical engineering systems are designed and controlled to operate at peak function with minimal waste.
3.  Embodied carbon optimisation encourages engineers to select materials that require less energy to produce and transport, which balances with operational efficiency.
4.  Adaptability, which assumes that buildings will not always be used for the same things, and asks how we can design spaces for easy reconfiguration in future.

These are the four pillars on which sustainable engineering design rests. They are an excellent guide for both developers and engineers who aim to build greener, and the principles themselves are constantly becoming more nuanced as we innovate in this space.

How Sustainable Engineering Design Improves Your Development

While the environmental benefits are clear, the business case for sustainable engineering design is just as compelling for developers and the city at large. Let’s look a bit deeper.

Significantly less expensive to operate.

The most immediate benefit is the bottom line. By optimising your mechanical engineering systems for sustainability, we can drastically lower your building’s energy and water consumption.

For a commercial skyscraper, even a 10% or 15% increase in efficiency translates to hundreds of thousands of dollars saved in utility costs over the building’s lifespan.

Compliant now and in the future.

New Zealand has increasingly stringent building codes and carbon neutrality targets, all of which are likely to become even tougher. If you are currently building, adopting sustainable engineering design now helps insulate your investment against future changes in legislation.

Increased appeal for potential tenants.

Your target for tenants might be multinational corporations or urban-focused premium residential buyers. In either case, many are now looking for green-star-rated spaces they can utilise.

Because of the specialised design work required, sustainable buildings often command higher rents and enjoy lower vacancy rates, as they are healthier and more modern than most other options. As the developer of the space, this is a major boon to you.

A more resilient urban space.

Urban buildings face some of the harshest conditions, both due to the surrounding environment and the increased foot traffic in a dense population centre. The more that sustainable engineering design principles become commonplace, the more we see how they take pressure off ageing infrastructure.

For example, a building that can manage stormwater on-site and reduce peak-load demands on the electrical grid is far more likely to be a celebrated addition to a stable urban environment. Auckland is fairly geographically constrained, so smart building practices are essential to ensure we build a wide-spanning network of sustainable developments that benefit the city as a whole.

More comfort for your tenants.

Sustainability and comfort go hand-in-hand. Better thermal regulation, natural light, and superior indoor air quality are the markers of a high-quality building. Happy, healthy tenants are long-term tenants, which provides the stability every developer aims for.

In short, adhering to sustainable engineering design principles absolutely offers short-term benefits to you as a developer, but the long-term benefits are unrivalled. Your final building performs better, lasts longer, and is far less likely to run into significant legislative challenges down the line.

Since sustainable engineering is relatively new compared to other schools of engineering, embodying these principles in your development is best done with the expertise of sustainable engineering consultants who can guide your choices.
