Buildings affect their surroundings and are affected by them in turn. DINETT quantitatively predicts the interplay of light, wind, sound and heat to get projects through review — and goes further, to certifications that raise building performance and asset value.
In building environment work, most project delays stem not from technical impossibility but from starting required reviews too late. Responding only after the review board raises issues sets off a chain of design changes and re-reviews.
At the earliest planning stage, DINETT identifies every review, assessment and certification item the site and use require, all at once, and first delivers a roadmap worked back from each submission deadline. Our first task is to make clear which reviews sit on the permitting critical path.
The review items are also interlinked. Placing buildings to secure sunlight can worsen the wind environment; enlarging windows improves daylighting but lowers energy performance. DINETT optimizes these trade-offs simultaneously within one team.
We group our capabilities by where they fall in the permitting process. Review response, performance prediction and certification differ in the form of deliverables required and the weight of responsibility.
We submit the items required by local building committees and by landscape and educational environment reviews, backed by quantitative evidence. Preventing resident complaints and disputes in advance is also a goal of this stage.
We assess combined building environment impacts — sunlight, noise, airflow, light pollution and more — against local building committee criteria and prepare the response report. Rather than preparing each item separately, we derive all results from a single 3D model to keep them consistent.

We measure continuous and total sunlight hours on the winter solstice and analyze shadow extents, submitting reports that prevent sunlight-rights disputes.

We simulate glare caused by light reflected off glass facades and diagnose actual impact through real-time illuminance and luminance measurement. Presenting predictions alongside measurements builds the evidence base for responding to complaints.

Using 3D models, we simulate and report on sightline obstruction, view retention ratio and privacy impacts for areas adjacent to housing.

We find on the drawings the problems that would otherwise surface after completion. We calculate the behavior of wind, light, heat and sound to adjust layouts and details, and where needed the same team carries out the mitigation works.
We provide mitigation design for construction, road and HVAC noise, non-destructive vibration measurement, soundproofing and vibration isolation works, and integrated architectural acoustics design. Because prediction → design → construction → post-construction measurement form one continuous flow, the same team is accountable for verifying the actual effect of the measures.

We distinguish mandatory from optional certifications and calculate in advance the achievable rating and the scope of design changes it requires. Setting the target rating first and working back saves the most in project costs.
We diagnose energy performance through simulation combining envelope insulation, renewable energy share and load calculations, and prepare permitting documents. Since the cost of earning the same points varies widely by item, we propose improvements in order of cost-effectiveness.
