Energy Net Zero LEED
This 12,000 SF two story facility in Bartlett, Illinois, received LEED Gold certification. WCL is the engineer of record and LEED project administrator for the design which includes occupancy-controlled lighting, very high efficiency air-cooled air conditioning, condensing furnaces, energy recovery ventilators, economizers, and low water consumption plumbing fixtures.
Extensive DOE2.1 energy simulations were used to model geothermal heat pumps, water-source heat pumps, high efficiency chillers, and high efficiency split systems. Several different types of vision and day lighting glass were modeled, as were various lengths of the overhangs and light shelves.
F-Chart simulations modeled the solar thermal and photovoltaic systems, and geothermal software was used to estimate the size of the geothermal field.
Energy costs for the facility are approximately 40% less than a similar structure built to the current Code.

A new 13,000 SF residence and estate in the lemon groves of Fallbrook, California. With a 1280 SF solar heating system that annually provides over 80% of the space, domestic hot water, and pool heat, at the time it was one of the largest residential systems in the state. Numerous computer energy simulations helped design the system and determine the lowest life cycle costs.

205 West Wacker Drive, formerly known as the Engineering Building, is a 25-story high-rise office building containing approximately 325,000 square feet and includes a 60-car indoor valet parking garage and two basement levels. The office building was designed by Burnham Brothers
Weber Consultants was commissioned to identify energy conservation investment opportunities and make recommendations for implementation. We studied the energy consumption relative to other buildings in the EPA’s Energy Star Program and were able to obtain an Energy Star Rating of 90 for the building.

Built in 2000, the Guest House has been a home to conference attendees of the Johnson Foundation. Part of an overall energy study performed by Weber Consultants in 2006, we recommended that the building would be a good candidate for LEED certification, given the Foundation’s interest in conservation and sustainability. In 2009, with help from WCL, The Guest House achieved LEED O+M: Existing Buildings, v3 LEED 2009.
This new 16 KW photovoltaic system went online in the spring of 2007. It produces over 20% of the Guest House’s annual electricity needs.
