Our Services

At Simstream, we bring over a decade of expertise in building physics and environmental simulation to every project. Our services are designed to optimise comfort, harness natural daylight, reduce energy use, and ensure regulatory compliance — helping you create spaces that are not only sustainable but also deeply human-centred. From concept design to construction, we deliver insights that turn ambitious ideas into high-performing, future-ready buildings.

Comfort

Comfort

We use advanced simulation tools to predict and optimise thermal comfort, air quality, and acoustic performance, ensuring your spaces feel as good as they look. By combining detailed modelling with real-world insights, we help create environments that promote wellbeing and productivity for the people who use them.

With over a decade of experience in building physics, our team has guided projects ranging from residential developments to large-scale commercial and public infrastructure. We apply proven expertise in thermal modelling, ventilation strategies, and occupant behaviour analysis to deliver comfort-driven solutions that balance performance with human experience.

Daylight

Daylight

Natural light is a vital ingredient in sustainable, healthy buildings. Our daylighting simulations assess access to sunlight, glare, and overall light quality to inform design decisions that enhance visual comfort, reduce reliance on artificial lighting, and align with wellbeing standards.

Our specialists have worked alongside leading architects and engineers to shape daylighting strategies for projects of all scales. Drawing on in-depth knowledge of simulation software and international daylighting standards, we translate complex modelling outputs into clear recommendations that help design teams achieve both creative and performance goals.

Energy

Energy

Energy efficiency is at the core of resilient, future-ready buildings. Through precise modelling of building fabric, systems, and operational scenarios, we provide actionable strategies to lower energy use, reduce carbon emissions, and optimise performance without compromising comfort.

Since 2008, we’ve partnered with top universities and engineering firms to tackle some of the most demanding energy challenges in the built environment. Our skills span dynamic thermal modelling, HVAC system optimisation, and renewable integration, allowing us to support projects in achieving ambitious sustainability targets and net-zero commitments.

Compliance

Compliance

From local planning requirements to international sustainability certifications, we ensure your project meets and exceeds regulatory standards. Our compliance services translate complex building codes and performance criteria into clear, practical solutions, helping you navigate approvals with confidence.

Our team has extensive experience in delivering compliance assessments across multiple jurisdictions, from Part L and EPCs in the UK to BREEAM, LEED, and WELL certifications internationally. We combine technical rigour with practical project knowledge, ensuring that your designs align seamlessly with regulatory frameworks while maintaining design intent and performance ambition.
