Early consultation supports an integrated approach: Assessing the overall building strategies of ventilation, cooling, heating and façade design early is beneficial.

  • Ventilation Overview

    RWDI’s consultants provide expertise in integrated design - to achieve effective ventilation, cooling and heating - to optimize building thermal performance at minimum energy cost. 

    RWDI’s recommendations produce climate responsive designs that improve air movement and distribution and mitigate undesirables such as condensation on cold surfaces, exposure of building occupants to hazardous contaminants, and elevated levels of stack effect infiltration and exfiltration.

  • Benefits

    • An enhanced indoor environment will increase occupant satisfaction and improve occupant health, safety and comfort.
    • Integrated design and high efficiency ventilation equipment can reduce a building's annual energy costs by much as 50%, while increasing comfort.
    • Early design for superior thermal performance can result in smaller and more efficient HVAC equipment, reducing building first cost and lower operational costs.
    • Buildings with enhanced indoor environmental quality can be valued at a premium.
    • Smoke management systems that perform as intended and increase occupant safety.
    • Contributes to an environmentally responsible building.

     

  • Issues

    • Effective air distribution.
    • Thermal comfort.
    • Innovative use of active and passive solar/wind chimneys.
    • Façade type (single versus double skin).
    • Glass selection.
    • Natural and hybrid ventilation.
    • Fire safety/smoke management.
    • Chemical and biological contaminant migration.
    • Reducing amount of conditioned airflow through buildings.
    • In health care facilities protection of patients and caregivers.
    • Condensation.
    • Radiant cooling and heating.
    • Rain & snow Infiltration.
    • Risk of drafts in sensitive interior spaces.
