☀ Daylight Intelligence for Rentals

Turn daylight into a leasing advantage.

We quantify when and how sunlight reaches bedrooms, Zoom rooms, and desks — then package it as a simple badge and scorecard prospects can trust.

All deliverables are marketing descriptors — not medical advice, not code compliance.

The Problem

Why daylight data matters now.

01

Photos can't show morning vs. afternoon sun.

Tours happen at one moment in time. "Sunny" is a subjective — and risky — claim in listings.

02

Two units in the same building can perform completely differently.

Because of orientation, floor plate, and urban shading. Generic building-level claims miss this entirely.

03

Mismatched daylight expectations slow lease decisions.

Credible, unit-specific light data reduces tour waste and shortens vacancy cycles.

What You Get

Productized daylight evidence.

Core Deliverable ☀️

Unit Daylight Scorecard

Time-of-day bands (morning / midday / evening) for each key room. Seasonal context included. Built on spatial daylight autonomy (sDA) and annual sunlight exposure (ASE) as technical backbone. Shows best-use windows per room in language prospects instantly understand.

Listing Asset 🏷️

Embeddable Daylight Badge

A simple, trustworthy badge for your listing pages and property site. Copy-paste ready. Signals credibility without overwhelming prospects.

Visual Proof 🎬

Seasonal Sunlight Clips

Short, visual proof of when light hits the desk, bedroom, or living area. Simple and persuasive for listings, social, and leasing packages.

The Science, Simplified

Light shapes how people live — and choose.

Ocular light exposure influences circadian rhythms and sleep regulation. Field research in residences has demonstrated improved circadian alignment when daylight access increases — not in labs, but in real homes.

Empirical studies have found that daylight-related variables are associated with meaningful housing price effects in real estate markets. Light isn't just wellness — it's an asset variable.

BrightUnit translates this science into daylight access descriptors: modeled data about when and how light arrives, expressed in plain language prospects can actually use to make decisions.

All BrightUnit deliverables are marketing descriptors — not medical advice, medical devices, or code/compliance reports.

sDA

Spatial Daylight Autonomy — floor area receiving sufficient daylight per year. IES LM-83 family.

ASE

Annual Sunlight Exposure — flags areas with too much direct sun for glare and thermal context.

EN 17037

European Daylighting Standard — covers daylight provision, view, sunlight access, and glare.

EML

Melanopic-weighted metrics (optional) — circadian-relevant light quantity, with strict non-medical disclaimers.

Common Questions

Got questions? We've got answers.

Is this a compliance report?
No. BrightUnit deliverables are marketing descriptors — not code compliance reports and not medical documents. They are designed to help leasing teams communicate daylight credibly, not to certify a unit against any regulatory standard.
What metrics do you use?
We use a two-layer approach: leasing-friendly metrics that prospects actually understand (e.g. "≥ X hours of morning sun in this bedroom"), backed by established technical metrics — spatial daylight autonomy (sDA) and annual sunlight exposure (ASE) from the IES LM-83 family. EN 17037 is used as a language bridge for daylight provision and sunlight access framing.
Can you compare units within one building?
Yes — and this is the whole point. Unit-level differentiation is what we're built for. Two units at the same address can perform completely differently based on orientation, floor, and urban shading. We surface exactly that difference, credibly.
How accurate is the modeling?
We use typical-year climate inputs and urban context geometry for credible simulated estimates. All outputs are labeled "modeled daylight access" or "estimated hours of direct sun" — never absolute guarantees. Furniture, blinds, finishes, and occupant behavior all affect real-world outcomes, which is why our copy packs include a clear limitations note.
Who is this best suited for?
Multifamily owners and operators, build-to-rent leasing teams, student housing and senior-living operators, and flexible office or hybrid workspace providers. If you have inventory where daylight is a genuine differentiator and you want to communicate it credibly, BrightUnit is built for you.
Can I make health claims using your reports?
No, and we actively help you avoid this mistake. Our marketing copy pack includes an approved phrasing guide and a do-not-say list. You can reference the science behind daylight and circadian health as context — but BrightUnit outputs are framed as daylight access descriptors, never wellness claims.
