GES provided MEP & FP engineering services for the addition of an 800-seat auditorium at Crossland High School. The new 18,350 sf addition is being built to support the performing arts program and will include an auditorium, stage, dressing rooms, storage rooms, Black Box Theater, ticket booth, projection room, office and lobby area. GES has designed a new geothermal system to provide the heating and cooling system to support the new auditorium.

As the prime contractor, GES provided electrical engineering services for the development of a solar panel system capable of providing 500-600 kW of new power to supplement NIST's existing kW system. Specific projects include:

Laboratory Building 216: A 1200-module ground based photovoltaic array providing a system capacity of 252 kWp with first-year minimum energy output of 327 MWh, and first-year yield of 1299 kWh/kWp.

Laboratory Building 227: A 1152-module shade canopy mounted array including pre-engineered canopy structures over the existing parking areas configured to provide a system capacity of 241.92 kWp with first-year minimum energy output of 279 MWh, and first-year yield of 1154 kWh/kWp.

Administration Building 101 Roof Area: A ballasted, roof mounted 336-module array configured to provide a system capacity 70.56 kWp with first-year minimum energy output of 78.5 MWh and first-year yield of 1112 kWh/kWp.

Facility Services Building 301 Roof Area: A ballasted, roof mounted 36-module array configured to provide a system capacity of 7.56 kWp with first-year minimum energy output of 8.3 MWh and first-year yield of 1098 kWh/kWp. Work also included vehicle charging stations for the support of electric vehicle charging with instructional signage describing charging operations.

GES provided engineering services to evaluate the condition and energy usage for their existing MEP systems and identified ways to improve the energy efficiency of these systems, while reducing the overall operation and maintenance costs.

Based on requests from DDOE, DGS required an energy model be prepared to compare the performance of the school prior to the Phase 1 Modernization versus the school post renovation. GES developed a base line energy model that could be applied for the entire facility, but focused on the area of work that was renovated. The baseline model was developed based on ASHRAE 90.1 and modified as needed to depict real building values. Upon completion, GES coordinated with the DC SEU to assist the client in receiving funding for energy related improvements based on GES’ energy analysis.

GES provided a facility condition assessment for OTS 494,000 gsf Headquarters Building. As part of the project, an initial survey of the existing systems was completed which allowed for an evaluation of the building condition and development of opportunities to enhance sustainability and energy efficiency. The result was a comprehensive ten-year plan for building-wide systems and components upgrades, which included a conceptual design for an immediate and long term strategic plan.

Replacement of two inoperable chillers with high efficiency water cooled centrifugal chillers with VFDs, two cooling towers and pumps. The new chillers support both the existing nursing home facility, as well as a planned expansion that will add 50% more floor area. GES alos developed the load calculations and life cycle cost analysis.

Replacement of two existing chillers with high efficiency water cooled centrifigul chillers with VFDs, two cooling towers and pumps. This allows for a lead lag configuration with one system in place and one in standby to ensure 24/7 operations. The chillers will support the existing research building, as well as an 8,000 sf future expansion. GES also developed the load calculations and life cycle cost analysis.

As the prime contractor, GES is providing mechanical, electrical and plumbing engineering services to complete an energy efficiency and solar energy feasibility study. This includes an analysis of the current and historical energy use data and design of a rooftop solar thermal water heating system to reduce the cost of heating the facilities hot water. The study will prioritize recommendations through a comprehensive review detailing initial costs, ongoing maintenance requirements, life cycle costs, anticipated savings, and Green House Gas emissions reductions.

SOME is an interfaith, community-based organization in Washington DC that offers comprehensive, holistic approach to caring for the homeless and extremely poor citizens of the city. One of the apartment buildings, The Chabraja House home to 53 single adults had a solar thermal water heating system installed to supplement the water heating needs. The system will use fluids from the solar collectors to circulate through a 20 sf copper finned solar removable heat exchanger with in the water tank.
