Leadership in Energy and Environmental Design (LEED)

LEED is transforming the way we think about how our buildings and communities are designed, constructed, maintained and operated across the globe. Comprehensive and flexible, LEED is a green building tool that addresses the entire building lifecycle recognizing best-in-class building strategies.

At its core, LEED is a program developed by the US Green Building Council that provides third-party verification of sustainable buildings. Building projects satisfy prerequisites and earn points to achieve different levels of certification. Prerequisites and credits depend on the project type (selected rating system), and teams choose the best fit for the project. 

What can LEED do for you?

  • Lower operating costs
  • Increase the asset value
  • Conserve energy, water and other resources
  • Be healthier and safer for occupants
  • Increase the productivity and comfort of the occupants
  • Increase marketability
  • Gain international recognition and prestige

1 billion square meters of space has been certified using LEED around the world, with 170 thousand more square meters certifying daily. Your project will be in good company among the most efficient, high-performing buildings across the globe.

General Credit Requirements:

Mechanically Ventilated Spaces

 Increase breathing zone outdoor air ventilation rates to all occupied spaces by at least 30% above the minimum rates required by ASHRAE Standard 62.1-2007 or by the CEN standard EN 15251:2007 as determined by IEQ Prerequisite 1: Minimum Indoor Air Quality Performance.

 Naturally Ventilated Spaces

 Use a macroscopic, multizone, analytic model to predict that room-by-room airflows will effectively naturally ventilate, defined as providing the minimum ventilation rates required by ASHRAE 62.1-2007 section 6, for at least 90% of occupied spaces. Projects outside the U.S. may use Annex B of Comité Européen de Normalisation (CEN) Standard EN 15251: 2007.

Compliance Service:

Internal and external airflow models are provided in order to prove compliance with the requirements in naturally ventilated spaces as well as for compliance calculations required for mechanical ventilated spaces as established in ASHRAE 62.1.

General Credit Requirements:

Use on-site renewable energy systems to offset building energy costs. Credits are awarded for a percentage of renewable energy used on-site from 1% to 13%.

Compliance Service:

Facilitate in the selection of energy systems by the assessment of the project for nonpolluting and renewable energy potential including solar, wind, geothermal, biomass and bio-gas strategies.

Provide calculation of the project’s performance by expressing the energy produced by the renewable systems as a percentage of the building’s annual energy cost.
