In response to being awarded a Net Zero Energy School grant by the Maryland Energy Administration, Baltimore City Public Schools is funding the development and construction of Net Zero Energy designs for two new schools: Graceland Park/O’Donnell Heights Elementary/Middle School and Holabird Elementary/Middle School. Setty has been contracted by Grimm+Parker Architects to provide MEP/FP design for both schools. Graceland Park (84,774 sf) is being designed to fully achieve Net Zero Energy status, while Holabird (87,916 sf) will be designed to be “Net Zero Ready.” Both schools are expected to achieve minimum LEED Silver certification, and the target building Energy Use Index (EUI) for both facilities has been aggressively set at 25 kbtu/sr/yr or less.
Setty’s MEP/FP designs for both schools are expected to incorporate a variety of sustainable technologies. A closed-loop geothermal well field will work in conjunction with a water source heat pump to provide energy-efficient heating and cooling for portions of the buildings. Ventilation air will be provided by a Dedicated Outdoor Air System (DOAS), equipped with Variable Air Volume (VAV) terminal boxes and an energy recovery wheel. CO2 sensors located through the school buildings will modulate the amount of ventilation air provided by the VAV boxes. Lastly, roof-mounted photovoltaic arrays will provide on-site renewable energy generation.
Both new schools are expected to be ready for move-in by Fall 2018.
Setty has been contracted by Perkins Eastman Architects to provide complete MEP/FP design services for the construction of the new 21,500 sf Cleveland Park Library. The completed library is to achieve a minimum LEED Gold certification and will incorporate many sustainable technologies. Setty has been asked to provide two MEP/FP designs—a “standard” design, and an alternate Net Zero Energy design. If DCPS funds allow, the Net Zero Energy design will be chosen.
Regardless of which final design is chosen, the new library is expected to feature a range of sustainable technologies, including a ground source heat pump, geothermal wells, a Dedicated Outdoor Air System (DOAS) for ventilation, and an energy-efficient radiant floor heating system. Additionally, Setty expects to include roof-mounted photovoltaic arrays, LED lighting, and daylighting in its design.
The new Cleveland Park Library is expected to open by March 2017.
SETTY is investigating the feasibility of using an innovative combined heat and power (CHP) plant to serve four schools located in the District's new Southeast Eco-District. Because CHP plants effectively recover waste heat from the production of electric power, overall power plant efficiency is improved and the goal of NZE becomes more attainable.
Additionally, by using a biomass-powered fuel cell as the CHP's prime mover, on-site generation of renewable energy-a central tenant of NZE building design-is achieved. In the end, SETTY's proposed design not only realizes NZE, but it is projected to save the District over $300k per year in utility costs.
SETTY is providing MEP Design and Construction Administration services for the construction of a NZE demonstration home in Prince George's County, Maryland. By combining renewable energies-a photovoltaic array and solar water heating-with intelligent lighting and HVAC controls into the home design, this Urban Green-led project aims to show that NZE is a realistic option for low-income suburban residents. In both projects, SETTY's knowledgeable engineers are leveraging their expertise in high performing building practices to both serve our clients and advance state-of-the-art building technologies.
Setty is designing an innovative Net-Zero school facility with common HVAC and energy systems, but combined in a unique manner. The building is slated for four floors, with a total building area of 322,000 sf, and include a large football stadium.
The District of Columbia is pursuing LEED Platinum as well as a Net Zero Energy Building.
