How can we achieve sustainability and profitability at the same time?

This is one of the most common questions I receive from audiences and companies alike. In this article, I will explore how buildings can achieve both goals without compromising one another by leveraging emerging technologies. These insights are drawn from my recent webinar with Frost & Sullivan at the end of last month.

My webinar with Frost & Sullivan on 29 July 2025

1) IoT & Smart Building Controls

Smart Buildings from Johnson Controls

IoT sensors and smart building controls enable operators to monitor occupancy, temperature, lighting, and indoor air quality in real time and automatically optimise systems based on actual usage. These applications result in lower energy use, reduced operational waste and improved tenant comfort.

In practice, such deployments commonly achieve energy savings of 15–30%, depending on the baseline and scope of controls. For example, a centralised smart-building platform deployed across 400+ buildings in Malaysia reported roughly 15% energy savings and achieved a Green Building Index (GBI) Gold standard — demonstrating measurable reductions alongside improved asset performance.

2) AI & Predictive Analytics

AI-driven optimisation and predictive analytics are especially effective for Heating, Ventilation and Air Conditioning (HVAC) systems. By forecasting loads, anticipating faults and optimising plant schedules, these tools reduce carbon emissions, lower operating expenditure, minimise unplanned downtime, and extend equipment life. This shift from reactive to predictive maintenance means fewer breakdowns, lower spare-parts costs, and longer replacement cycles — creating both environmental and financial benefits.

3) Generative Design & Climate Adaptive Façades

Generative design uses AI and simulation to model thousands of building configurations, optimising for daylight access, thermal comfort, embodied carbon and cost simultaneously. When paired with climate-adaptive façades — such as dynamic shading or electrochromic glazing — buildings can automatically respond to changing external conditions. These strategies enhance occupant comfort and can deliver substantial energy savings, with dynamic façades alone contributing up to 30% reductions in cooling and lighting loads.

4) Renewable Integration & Passive Cooling

On-site renewable energy systems, such as building-integrated photovoltaics (BIPV) paired with battery storage, reduce utility bills and improve ESG ratings while cutting the building’s carbon footprint. Complementing these with passive radiative cooling techniques — such as sky-facing roof panels that reject heat to the atmosphere — can eliminate up to 35% of daytime air-conditioning loads. Together, these high- and low-tech solutions create a powerful pathway to lower operating costs and greater resilience against energy price volatility.

5) Mass Timber & Engineering Wood Construction

Mass timber and engineered wood products like cross-laminated timber (CLT) store carbon within their structure, significantly reducing embodied emissions. They also speed up construction timelines, simplify deconstruction and allow for future reuse of materials, supporting circular economy goals. Beyond environmental benefits, these materials appeal to tenants and investors seeking sustainable, high-performance buildings.

6) Retrofitting & Smart Urban Renewal

Strategic retrofits — from advanced building management systems (BMS) to integrated digital twin platforms — can extend an asset’s lifespan while reducing energy use and improving returns.

Keppel Bay Tower in Singapore

For example, Keppel Bay Tower in Singapore invested around USD 2.6 million (about 0.7% of the asset’s value) in retrofits, achieving a 30% cut in energy consumption through smart lighting, HVAC optimisation and performance monitoring. Such upgrades often deliver faster Return on investment (ROI) than new builds, preserve capital and unlock hidden value in existing stock.

Financial and Operational Trade-offs

While the technologies above offer strong potential, pursuing sustainability often carries short-term costs and operational complexities.

Financial Considerations:

Higher upfront capex: Green-certified designs can cost roughly 3–10% more than conventional builds because of enhanced insulation, advanced HVAC, certification fees and specialised materials. In some cases, overall construction premiums can approach ~6%, squeezing developer margins.

Payback timeline: Recovery of premium costs varies — some schemes see payback in 2–6 years depending on certification level, incentives and market rents.

Operational Considerations:

Increased maintenance complexity: Green roofs, advanced BMS and integrated renewables can raise Operations and Maintenance (O&M) demands and require skilled personnel. A green roof may cost more to install and maintain and could need structural reinforcement.

Performance risk: Without rigorous modelling, commissioning and sustained O&M, real-world performance can fall short of expectations. Occupants may override systems, or poor commissioning may lead to excess energy use.

Short- and long-term impacts — At a Glance

Capex premium — In the short term, higher build and certification costs can increase project expenditure. In the long term, these investments can lead to operational savings, higher rental premiums and uplifted asset value.

Payback delay (2–6+ years) — In the short term, the extended payback period can create cashflow pressure, especially for cost-sensitive projects. In the long term, the returns generated over the building’s lifecycle can be highly profitable.

Operational complexity — In the short term, specialised maintenance requirements and potential inefficiencies can add to operational burdens. In the long term, well-managed systems can extend asset life and enhance tenant experience.

Performance uncertainty — In the short term, there is a risk of missing energy or performance targets. In the long term, when systems are properly commissioned and maintained, they can deliver high reliability, reduce total cost of ownership and strengthen ESG performance.

Key Trends Shaping the Next Wave of Sustainable Growth in the Buildings Sector

Circular & smart materials — self-healing concrete, phase change materials (PCMs) reduce maintenance and smooth thermal loads.

Phase Change Materials (PCMs) are substances that absorb or release significant amounts of thermal energy during a phase transition, typically from solid to liquid or vice versa, at a relatively constant temperature.

Modular and prefabricated construction are building methods involving the off-site fabrication of building components or entire modules, which are then assembled on site.Modular and prefabricated construction are building methods involving the off-site fabrication of building components or entire modules, which are then assembled on site.

Modular & prefabricated construction — less waste, faster delivery and higher quality control.

Digital twins, BIM & predictive analytics — enable lifecycle management from design through operations, increasing reliability and driving continuous improvement.

Practical Advice: Balancing Ambition with Reality

Start with high-impact, low-cost measures — Prioritise no-regret actions supported by digital tools (BIM, energy analytics) and material optimisation.

Phased or hybrid investments — Retrofit first, then scale; combine small capital projects with performance contracts.

Use performance guarantees — Energy-savings contracts or performance-linked supplier agreements mitigate operational risk and align incentives.

Align with policy & incentives — Map grants, tax relief, Green Building schemes and carbon markets to your roadmap to shorten payback and pre-empt future compliance costs.

Conclusion

Sustainability and profitability are not mutually exclusive. The trick is to harmonise ambition with practicality. Prioritise interventions that deliver clear, measurable returns, de-risk projects via guarantees and digital controls and phase investments so cashflow and operational capacity are protected.

With smart deployment of IoT, AI, renewables, material innovation and retrofits, buildings can be both greener and more valuable — turning sustainability from a cost centre into a competitive advantage.
