From Climate Data toDesign Impact

C4B provides instant, data-driven climate and energy insights before design begins, guiding better decisions for architects, engineers and developers.

climate data

Climate Zone

Classifies the site using recognised systems (Köppen-Geiger and ANSI/ASHRAE), with reference maps and legends explaining each climate class and zone.

design direction

Passive Design Strategies for Indoor Environments

Uses a Givoni-style climate analysis to recommend the most effective passive strategies (natural ventilation, thermal mass, passive solar heating, and others) and the share of hours each one can address.

energy data

Country Grid Carbon Intensity Assessment

Shows the carbon intensity of the national electricity grid, benchmarks it against other countries, and breaks down the electricity generation mix by source.

design direction

Comfort Strategies for Outdoor Environments

Tests outdoor interventions such as shade and wind shelter, showing how each one raises the share of comfortable hours by season and time of day.

climate data

Annual Wind Rose Diagram

Maps the frequency, direction, and speed of wind across the year, with speed bands linked to which outdoor activities remain comfortable.

energy data

Solar Radiation

Displays the solar energy reaching the site across its three components (direct normal, diffuse horizontal, and global horizontal), interpreted for photovoltaic generation potential.

climate data

Precipitation Event Intensity

Shows how intense individual rainfall events are, useful for understanding storm severity and drainage needs.

mission

From your first sketch,not your final review.

This project began with a simple intention: to make climatic data more accessible and relevant for architects, promoters, and design teams.

At (embrace ideas), we wanted to explore what happens when climate and energy information which feed more sustainable and resilient building design is available from the first step. This information would no longer be a part of a 'sustainability checkbox', but a core part of the design process itself.

C4B was built to bridge the gap between complex data and early-stage conceptualization, equipping you with the insights to integrate climate and energy data efficiently, clearly, and proactively

Common practice

Common practice process: design, climate data analysis, validation, redesign, and delivery.

Climate4Buildings process: design direction and climate energy data inform design before validation and delivery.

who it’s for

architects

Good architecture already understands where it stands.

Bring your site's climate into the very first sketch, not the final review. C4B turns the raw climatic conditions of any location into design direction you can act on: passive design strategies, outdoor comfort strategies, and the climate context (solar path, wind roses, UTCI comfort) that shapes a considered response from day one. Then export it as a report your team and your client can actually read.

engineers and sustainability specialists

Reliable climate and energy data from any location on the globe.

Pull a consistent, technically sound climate and energy stack for any coordinates worldwide: EPW files, psychrometric analysis, solar radiation, PV and wind potential, and grid carbon intensity. Built to sit alongside your expertise, turning hours of data-gathering into minutes, not to replace the judgment you bring to it.

promoters and developers

Climate and energy insight, ready for the decisions that come first.

Understand the site's climate and energy profile early, before the big decisions are made, in a format you can put in front of a board or a client without a technical translator. Readable reports covering local conditions, on-site energy generation potential and grid carbon intensity give you an early, defensible read on where a project stands.

platform

Enter a location. Get clear data.

No scripts. No weather-file wrangling. C4B automatically collects and processes site-specific climate, energy and comfort data into a report you, and the rest of your team, can actually read.

step 01

drop a pin

Type an address or click a map. We pull historical weather, regional grid intensity, and local solar & wind resource for the exact coordinates.

step 02

we compute

Sun paths, wind roses, UTCI comfort, PV potential, geothermal feasibility. A full climate & energy stack, site-specific.

step 03

you design

Receive a curated set of diagrams and design directions, ready to drop into a competition, a brief, or the first conversation with a client.

Every report brings together climate, energy and design direction, with each output explained, contextualised, and ready to use.

site specific EPW

Your actual site, not the nearest weather station.

Many readily available weather files are tied to the closest weather station, which can be kilometers away from your site, at a different elevation, in a different microclimate. In some contexts this gap in context is fine, but in others, the difference in weather data is substantial.

C4B builds an EPW anchored to your project's exact coordinates, so the climate you design against represents the site itself, not a proxy some distance away.

intelligence

The data, read for you.

Across your project overview and inside every module, each graphic comes with a written interpretation: what it's showing, and what it means for your site. In the design direction modules it goes further, reading your turning solar radiation, prevailing wind and the rest of your site's climate into passive design strategies. Every insight is generated only from your project's own data, drawn from the results on the page, so it stays grounded in your site and nothing else.
