LEED Certification

Leadership in Energy and Environmental Design (LEED) is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies intended to improve performance in metrics such as energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

What does LEED certification mean for you?

> Reduction of waste sent to landfills
> Conservation of water and energy
> Reduction of greenhouse gas emissions
> Qualify for tax allowances, zoning accommodations and other incentives
> Lower costs of operation and increased asset value

In addition to the above there is also the peace of mind of knowing that you show that you genuinely care about the environment and the social responsibilities you have as a business. Green buildings promote healthy living by existing in harmony with the environment. They decrease carbon emissions by using energy efficient appliances and bio-degradable or recyclable materials.

Khalifeh & Associates has a great deal of LEED Certification experience. Learn more about our recognitions as a leader in LEED Certification here.

Comissioning Services

Commissioning is a third-party verification of a building’s energy-related systems to confirm that these systems are performing as set forth by the owner’s project requirements. A quality assurance-based process, commissioning delivers preventive and predictive maintenance plans, tailored operating manuals and training procedures for all users to follow. Our commissioning services are in accordance with LEED and are based on ASHRAE Guideline 2005,
  • Heating, ventilation, air conditioning, refrigeration and respective controls
  • Lighting and daylighting controls
  • Domestic hot water
  • Renewable energy

At the end of the construction, Khalifeh verifies all energy using equipment is installed and running per the design and specifications – assuring your building is not wasting energy and is functioning properly during occupancy.


Heating, A/C & Ventilation Design

The main purposes of a Heating, Ventilation, and Air-Conditioning (HVAC) system is to help maintain good indoor air temperature while also providing adequate ventilation and air filtration, ensuring the quality of the air in your facility. HVAC systems can consume a great deal of energy so the choice and design of the HVAC system is very important. Khalifeh & Associates is experienced in designing high quality and efficient heating, air conditioning and ventilation systems.

Let our award winning engineers design a quality system that will ultimately save you money while efficiently providing an indoor air quality that is maintainable, cost-effective, and enjoyed year round.


Title 24 Compliance & Energy Analysis

The California Energy Code, or Title 24, Part 6 of the California Code of Regulations, also titled The Energy Efficiency Standards for Residential and Nonresidential Buildings, were established in 1978 in response to a legislative mandate to reduce California’s energy consumption. The standards are updated periodically to allow consideration and possible incorporation of new energy efficiency technologies and methods.

Khalifeh & Associates offers Residential & Commercial Title 24 Energy Calculation Services to homeowners, architects, designers, and builders. After reviewing your facility’s design, we ensure that energy calculations are taken accurately and efficiently to ensure compliance to energy standards.


Mechanical, Electrical and Plumbing Engineering Services

Mechanical and electrical engineers are specialists, commonly referred to as “MEP” (mechanical, electrical, and plumbing) when engaged in the building design fields. Mechanical engineers design and oversee the heating ventilation and air conditioning (HVAC), plumbing, and rain gutter systems. Plumbing designers often include design specifications for simple active fire protection systems, but for more complicated projects, fire protection engineers are often separately retained. Electrical engineers are responsible for the building’s power distribution, telecommunication, fire alarm, signalization, lightning protection and control systems, as well as lighting systems.
