Green Buildings

...

Designed Green...

With building owners facing rising energy costs and reduced operations budgets an increasing number of them are looking to sustainable or green building practices in order to create efficient, healthier and socially responsible facilities. Experience clearly indicates that designing buildings with life cycle cost in mind not only provides significant environmental and social benefits, but also make good economic sense. Control Services’ LEED® Accredited Professionals have the experience and knowledge to assist building owners and designers in developing sustainable solutions for both new construction and renovations.


Energy Audits by Leed Professionals

...

Where are you losing money...

A site energy audit helps owners determine where their buildings are losing energy and money - and how such problems can be corrected to make the buildings more energy efficient.

Energy audits are the first step to assess how much energy your business consumes and to evaluate what measures you can take to make your buildings more energy efficient. An assessment will show you problems that may, when corrected, save you significant amounts of money over time.

A LEED certified professional from Control Services can give your business a checkup.

Retrocommissioning

...

Rebalancing your energy usage

Retrocommissioning is the term for applying the commissioning process to a building that has been commissioned previously (either during construction or as an existing building); it is normally done every three to five years to maintain top levels of building performance and/or after other stages of the upgrade process to identify new opportunities for improvement.

Retrocommissioning is the first stage in the building upgrade process. The staged approach accounts for the interactions among all the energy flows in a building and produces a systematic method for planning upgrades that increases energy savings. When the staged approach is adopted and performed sequentially, each stage includes changes that will affect the upgrades performed in subsequent stages, thus setting up the overall process for the greatest possible energy and cost savings. In this staged approach, retrocommissioning comes first because it provides an understanding of how closely the building comes to operating as intended. It also helps to identify improper equipment performance, what equipment or systems need to be replaced, opportunities for saving energy and money, and strategies for improving performance of the various building systems.

Specifically, retrocommissioning is a form of commissioning. Commissioning is the process of ensuring that systems are designed, installed, functionally tested, and capable of being operated and maintained according to the owner’s operational needs. Retrocommissioning is the same systematic process applied to existing buildings that have never been commissioned to ensure that their systems can be operated and maintained according to the owner’s needs. For buildings that have already been commissioned or retrocommissioned, it is recommended that the practices of recommissioning or ongoing commissioning be applied.



What is LEED

LEED, or Leadership in Energy & Environmental Design, is redefining the way we think about the places where we live, work and learn. As an internationally recognized mark of excellence, LEED provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.

With 10.5 billion square feet of building space participating in the suite of rating systems and 1.6 million feet certifying per day around the world, LEED is transforming the way built environments are designed, constructed, and operated.

How does LEED work?

LEED certification provides independent, third-party verification that a building, home or community was designed and built using strategies aimed at achieving high performance in key areas of human and environmental health: Sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality.

Prerequisites & Credits

Each category in a LEED rating system consists of prerequisites and credits. Prerequisites are required elements, or green building strategies that must be included in any LEEDcertified project. Credits are optional elements, or strategies that projects can elect to pursue to gain points toward LEED certification. LEED prerequisites and credits work together to provide a common foundation of performance and a flexible set of tools and strategies to accommodate the circumstances of individual projects.

Points & Levels of Certification

LEED rating systems generally have 100 base points plus six Innovation in Design points and four Regional Priority points, for a total of 110 points (LEED for Homes is based on a 125-point scale, plus 11 Innovation in Design points). Each credit is allocated points based on the environmental impacts and human benefits of the building-related impacts that it addresses. Projects achieve certification if they earn points according to the following levels:

Updates to LEED

The hallmark of LEED and its ability to affect market transformation is its continuous improvement cycle that enables the rating system to increase in scope and stringency as market readiness increases and new technologies become widely available.

LEED v4 , the next version of the rating system, will focus on increasing LEED's technical rigor, expanding the market sectors able to use LEED, and striving for simplicity in terms of usability. LEED v4 optimizes the foundations in LEED 2009, and will continue to improve the clarity, usability, functionality and interconnectedness of the rating systems through future version development.

How is LEED Developed?

LEED rating systems are developed through an open, consensus-based process led by USGBC member-based volunteer committees, subcommittees, and working groups, in conjunction with USGBC staff, and are then subject to review and approval by the LEED Steering Committee and the USGBC Board of Directors prior to a vote by USGBC membership.

BUILDING PERFORMANCE

The Building Performance Partnership is a comprehensive data collection and analysis infrastructure that receives data from LEED-certified projects, both commercial and residential. It is the next step for projects that want to continue to monitor, understand and improve their building's performance.


LEED Rating Systems

Rating systems are groups of requirements for projects that want to achieve LEED certification.

Each group is geared towards the unique needs of a project or building type. LEED is flexible enough to apply to all project types including healthcare facilities, schools, homes and even entire neighborhoods.

Projects earn points to satisfy green building requirements

Within each of the LEED credit categories, projects must satisfy prerequisites and earn points. The number of points the project earns determines its level of LEED certification.
