The DAL 358 swirl diffuser
can contribute to achieving the requirements of LEED certification
LEED is a third-party certification program and an internationally accepted benchmark for the design, construction and operation of high performance green buildings.
It provides building owners and operators the tools they need to have an immediate and measurable impact on their buildings’ performance.
LEED promotes a whole-building approach to sustainability by recognizing performance
in five key areas of human and environmental health:
ustainable site development
indoor environmental quality
Credits and Prerequisites are organized into these five categories.
An additional category, focusing on
innovation, addresses sustainable building expertise, exemplary performance, and design (or operational)
measures not covered under these five environmental categories.
Certification is based on the total point score achieved, following an independent review.
With four possible levels of certification (certified, silver, gold and platinum),
LEED is flexible enough to accommodate a wide range of green building strategies
that best fit the constraints and goals of particular projects.
The Canadian rating systems are an adaptation of the
US Green Building Council's (USGBC) LEED Green Building Rating System,
tailored specifically for Canadian climates, construction practices and regulations.
The rating systems are adapted to the Canadian market through an inclusive process that engages
stakeholders and experts representing the various sectors of the Canadian industry.
The swirl diffuser DAL 358 can contribute to achieving the requirements of two (2) prerequisites and five (5) credits
thus to a potential of fourteen (14) possible points for
a proposed new construction or major renovation to a LEED Canada- NC version 1.0
|# Credit||Name of credit||Potential points||Contribution of DAL358 diffuser|
|ENERGY AND ATMOSPHERE|
|EAp2||Minimum Energy Performance||0 (required)||DAL358 Air diffusers contribute to reach the
minimum energy efficiency for the building.
|EAc1||Optimise Energy performance||
1 to 10 points possible according to energy performance of the building
|DAL358 air diffusers help obtaining an energy performance higher standards for construction.
*Note : a unique product can not determine the achievement of LEED® credits; they depend on the design project and strategies used.
|INDOOR ENVIRONMENTAL QUALITY|
Minimum IAQ Performance)
Tested according to ASHRAE Standard 129,
With Ez = 1.1, the DAL358 allows for an increase in the efficiency of the air flow. These performances also allow for a reduction of 27% of outdoor air rate.
Thermal confort :
DAL358 air diffusers help provide a ASHRAE 55-2004 comfortable environment terms of temperature of the building.
|MATERIAL AND RESOURCES|
he mechanical and electric credit is excluded from the category of Materials and Resources,
|INNOVATION AND DESIGN PROCESS|
|IPDc1.1||Innovation and design process||
Exemplary performance for EAIc1 : Optimise energy performance.
|IPDc1.2||Innovation and design process||
Exemplary performance for QEIc2 : Increasing the efficiency of ventilation.
