Passive design by way of definition is a simple logical approach to design that uses the building’s architecture, orientation and envelope to minimize energy consumption and to optimize natural light and user comfort. 

The key elements are based on the combination of the following principles: 

  • Building location and orientation on the site.
  • Façade design – how you design the outside “skin” of the building.
  • Sun shading and glare control.
  • Thermal comfort and insulation.
  • Access to natural light and ventilation.
  • Material specifications.
  • Landscape and planting – the concepts of biophilia and biomimicry.

The typical energy saving techniques we have applied to the electrical installation are as follows: 

  • LED light fitting will be used throughout the building.
  • Motion sensors will be used in the parking levels and common areas.
  • A PV system will be installed to generate electricity to supplement the council supply.
  • A building management system will be installed to monitor the metering of electricity and
    water supplies, which tenants will have access to.
  • Provision will be made for electric vehicle charging stations.
  • Provision will be made for metered generator backup supply to tenants.

The typical energy saving techniques we have applied to the mechanical installation are as follows: 

  • The electric lifts will contain energy efficient motor drives that will automatically shut down the lifts progressively whenever there is no demand for the lifts, as would typically be the case after hours.
  • The air-conditioning systems are VRV heat-pump units that operate with high efficiency. The units
    use an environmentally friendly refrigerant gas and do not consume any water. The office areas are provided with a system that provides mechanically forced filtered fresh air into all areas in order to ensure good ventilation of the various occupied areas.
  • Water conservation will be implemented by using water saving fittings. Water sourced from the site basements will be used for toilet flushing.
  • The basement water will also be used for landscaping and irrigation, should the chemical content thereof permit it.
    The integration of these principles will not only enhance the quality of the workspace environment but will ensure a sustainable longevity to a timeless architectural design.
