Grand Bay National Estuarine Research Reserve

The Grand Bay National Estuarine Research Reserve (GNDNERR), established in 1999, is managed through a unique local, state and federal partnership designed to promote estuarine research and education within Mississippi’s Coastal Zone and its adjacent ecosystems. The LEED Gold Certified Building saves 54% annual energy cost compared to a baseline building (ASHRAE Standard 90.1-2001) for LEED v.2.1.

“Korber Energy Consultants has assisted Lord, Aeck & Sargent with energy analysis on several of our green building projects including a successful LEED Gold certification for the Grand Bay National Estuarine Research Reserve. Their deep knowledge of the nuances of LEED EAc1 documentation was a real asset to the project.”

Spring Creek Fire Hall, Whistler, BC Canada

(CBIP & LEED Compliance model, MNECB & ASHRAE 90.1-2001)
The Spring Creek Fire Hall was one of the first LEED (Leadership in Energy and Environmental Design) registered projects in Whistler. The Fire hall building incorporates green building technologies and reduces annual energy consumption by 21% compared to a LEED v2.0 Baseline building helping to achieve a LEED Silver Certification for this building design.

This project was modeled for Hughes Condon Marler Architects in Vancouver, BC with Keen Engineering providing the mechanical and electrical design and energy modeling services. The energy simulation was performed using Visual DOE 3.0/DOE-2.1e to perform the energy compliance simulations required for LEED-NC Version 2.0. The simulation results were provided to the client showing 34% energy savings versus the baseline building case which contributed to achieving a LEED Silver rating on the building.
The building is a volunteer fire department station with a hose tower, three-bay garage, a few small offices, one conference/training room and a second level residence area. The building was designed for natural ventilation and uses increased insulation levels, high performance glazing, a planted (green) roof, and a high efficiency heating system to reduce annual energy consumption.
To reduce energy use in the fire hall a high efficiency furnace was installed in the living area to provide heat. Infrared heaters were installed in the apparatus bay in order to heat only the equipment and occupants working on the equipment. The domestic water heater is a high efficiency heater that will also reduce the energy usage on the building. This building did not require an air conditioning system. An air to air recovery unit was installed for ventilation which will recover approximately 50% of the rejected heat from the exhaust air. In addition to this an air intake located on the lower level of the tower brings in outside air and acts as a natural stack effect for ventilation.

Telus Whistler Conference Center, Whistler, BC

(LEED Compliance model, ASHRAE 90.1)
This project achieved LEED Silver Certification. The whole building was modeled to include the existing building spaces and the new addition. The building areas included a new entryway and public entrance, an updated conference facility and several community rooms with all new HVAC systems throughout the building. The building was designed for displacement ventilation in the primary conference areas and uses increased insulation levels, high performance glazing, demand controlled ventilation, and a high efficiency heating system to reduce annual energy consumption. All HVAC equipment installed was high efficiency including the use of variable frequency drives on fans and pumps. The building also makes use of daylighting strategies that reduced annual lighting energy consumption in perimeter spaces. Daylighting strategies included celestory windows, skylights and the use of photocell sensors to dim the building lighting systems as needed. The simulation results showed 26% energy savings over the baseline building model.
