What We Do

Technical studies and reporting at the intersection of design, regulation, and the built environment

Shadow duration study — net new shadow mapped across a project site

Shadow Studies

Quantitative shadow impact assessments, Section 295 compliance, shadow envelope studies, and location-duration heatmapping for CEQA and planning review.

Building massing colour-mapped by solar exposure during form studies

Shadow Shaping

Design-phase collaboration that shapes building form to reduce or eliminate shadow cast on parks, plazas, and other sensitive areas — resolving impacts before they become entitlement risk.

Photometric daylight analysis of an interior, showing a sunlight shaft

Daylight Studies

Comprehensive daylight access analysis evaluating natural light conditions for proposed developments and their impact on surrounding properties.

Photorealistic visual simulation of a proposed waterfront development

Visual Studies

Photorealistic visual simulations and photomontages that communicate complex design proposals to stakeholders, planning commissions, and communities.

Independent technical review of another consultant’s analysis

Peer Review

Independent technical review of shadow studies, visual simulations, and environmental analyses prepared by other consultants for quality assurance.
