Overview How we help How it works Benefits Projects Experts FAQs

Human-led. Performance-informed. Integrated design.

Having the right information at the right moment can make or break a project. When issues only surface late in the process, teams are left with limited options and expensive fixes that can slow delivery.

Daisy changes that. It brings the right specialists around the table during the earliest stages of a project, giving them the opportunity to shape more connected, more resilient building designs.

By drawing on real multidisciplinary expertise, supported by fast AI-powered simulation, structured analysis and advanced automation, Daisy helps teams compare options quickly and uncover optimal designs maximising whole‑building performance across carbon, energy, daylight and comfort – helping you understand the consequences of different designs and move projects forward with confidence.

How we help

At concept stage, Daisy gives you the insight to understand how early design choices ripple through whole building performance. It brings clarity to the choices that shape comfort, energy use and long term value, so you can make informed decisions and progress projects with confidence.

Massing and orientation studies

Explore early design options to see how form, height, orientation and layout influence carbon use, energy performance, daylight and comfort. This early clarity helps you shape a massing strategy that supports stronger whole‑building outcomes, shaping places that contribute to thriving people, communities and ecosystems.

Envelope studies

Test glazing ratios, shading strategies and facade choices to identify envelope options that deliver balanced daylight, comfort and energy performance. These insights allow you to refine the facade before key decisions are fixed, reducing late-stage issues.

Early systems sensitivity

Examine how initial services assumptions interact with architectural and facade choices to affect overall building performance. Understanding these relationships at the outset helps teams make informed decisions and avoid unnecessary re-design.

Custom concept-stage studies

When projects have specific performance questions, Daisy can focus on the variables and criteria that matter most. This tailored approach gives you the evidence you need to steer early design discussions with confidence and clarity.

How it works

Our co-design tool rethinks how buildings are shaped, bringing together people, data and AI intelligence to create future-focused designs.

01

Define

We work with you to set appropriate design options, constraints and performance goals for your project.

02

Simulate

We test how different choices impact key factors such as carbon, energy, daylight and comfort.

03

Compare

We show what improves, what conflicts and where risk sits across options.

04

Refine

You can use insights to refine the design, reduce uncertainty and focus effort where it will have the greatest impact.

How Daisy can benefit you

Daisy gives you the clarity to make smarter early design decisions that strengthen performance, reduce risk and create better project outcomes.

Better cost and programme management

Daisy allows you to use real data to test various optimal designs at concept stage, when there is flexibility to make changes and it’s more cost-effective to do. This means you can progress projects with more certainty, reducing late-stage redesign risk, optimising costs and limiting disruptions to delivery timelines.

Optimised building performance

Rather than looking at one issue separately, Daisy helps you see how choices across massing, facade, structure and building services affect performance together. This shapes more integrated building designs that are resilient and adaptable in an ever-changing landscape.

Stronger sustainability outcomes

Daisy enables you to analyse and maximise changes supporting low embodied carbon, better energy performance, improved daylight and reduced overheating risk during early project stages. This means your sustainability ambitions, such as BREEAM, WELL, NABERS and EPC certification, are not just achievable in design but deliverable in practice.

Projects we delivered

Gresham redevelopment

Using advanced analysis and multi-objective design exploration, Daisy helped the team compare options across daylight, energy use and embodied carbon – uncovering benchmark designs that supported a reduction in facade embodied carbon by 182tCO2 and saving of £420,800 by cutting facade area by 708m².

Anonymous residential envelope study

At RIBA Stage 3, Daisy simulated 14 representative apartment types and helped the team pinpoint facade changes associated with 45% lower overheating risk and 28% lower heating energy.

Anonymous healthcare optioneering

Daisy brought clarity to early optioneering, highlighting how different design paths affected whole‑building performance and helping the team weigh constraints and priorities with confidence.

FAQs

What is Daisy?

Daisy is our concept‑stage co‑design capability. It brings architects, engineers and analysts together early on, helping teams explore how choices in massing, facade, structure and building services influence energy use, carbon, daylight and comfort. It supports human decision‑making, it does not replace it.

How is Daisy different from standard early-stage analysis?

Typical early‑stage analysis often examines issues in isolation; Daisy looks at them together. By showing the interplay between comfort, energy, carbon and daylight, it helps teams understand trade‑offs sooner and avoid costly rework later.

Does Daisy tell architects what to design?

No. Daisy does not generate designs or dictate outcomes. It helps teams see and compare the impacts of their decisions so they can refine ideas with clarity and confidence.

When should Daisy be used?

Daisy is most valuable during concept and early design stages, when projects still have room to evolve and early choices have the greatest impact.

Can Daisy support planning, certification and project targets?

Daisy can help teams test early options against project ambitions and highlight risks earlier in the process. It strengthens evidence‑based discussions, but it does not replace the formal steps required for approvals, certification and/or compliance.

What is whole-building performance and how can Daisy benefit this?

Whole‑building performance recognises that design decisions are interconnected, improving one area can affect another. Instead of focusing only on metrics like cost, time or quality, it brings all performance objectives into a shared conversation.

Daisy works with this systems‑level view. It helps teams compare multiple objectives at once, daylight, thermal comfort, energy use and embodied carbon, and understand how to balance them. This joined‑up approach leads to clearer choices and better‑performing buildings overall.
