Northwest Housing VIII‐A features extensive underground utility relocations, including moving the campus’ main electrical and telecommunications feeder lines and extension of the campus chilled water and high temperature hot water campus loops . The project mechanical, electrical, and plumbing (MEP) systems are designed to maximize energy efficiency. The project incorporates low flow pumping systems to minimize pumping energy and fan coils with ECM motors for bed-room suites. The project is designed with low flow water fixtures to conserve water consumption and with high efficient lighting systems.

The buildings, of up to seven stories, will provide mostly four‐bed suites for the students. These cast‐in‐place concrete structures will have durable facades of brick, metal panels and glass curtain wall, and standing‐seam metal roofs. The project is being designed and will be built to meet USGBC’s LEED Silver sustainability standards.

Aronson

Client: Aronson & Co. Location: Rockville, MD

Encon provided services which include mechanical, electrical, plumbing, fire protection and life safety design for approximately 75,000 square feet for the tenant build out of Aronson’s new headquarters located in Rockville, MD. This project has the following components: multiple conference rooms, closed and open office areas, pantry areas, high density filing area, server room and IDF closets, and reception.

Prior to the selection of the new headquarters location, Encon assisted the project team in performing a MEP and FP location analysis of two proposed locations.

Our scope of work included visits to the project site as required during the preparation of the design documents to survey existing conditions, meetings with the project team, and internal document coordination meetings.

Encon also performed an onsite survey of the base building and of the project site to evaluate and become familiar with the existing conditions of the space and its architectural, mechanical, electrical, plumbing, life safety systems and provided solutions and or recommendations to correct or accommodate items which would impact the project requirements. Coordination with the base building landlord for emergency power, HVAC roof location, and adherence to base building standards was also performed.

Drawings were provided for the layout of all areas containing information technology and audio visual systems, interior spaces as well as private exterior offices. HVAC design included VAV terminal boxes, ductwork distribution, controls and supplemental server room cooling.

Blackboard Inc.

Encon also performed an on site survey of the base building and of the project site to evaluate and become familiar with the existing conditions of the space and its architectural, mechanical, electrical, plumbing, life safety systems and provided solutions and or recommendations to correct or accommodate items which would impact the project requirements.

Drawings were also provided for the layout of all areas containing information technology and audio visual systems. interior spaces as well as private exterior offices. HVAC design included VAV terminal boxes, ductwork distribution, controls and supplemental server room cooling..

There was significant MEP and FP above ceiling coordination on the project due the Client’s requirement to have maximum ceiling height which left the design team with little room for the systems. We had to provide above ceiling coordination drawings (ductwork, sprinkler, lighting) to make sure everything fit.

Harbor East

Client: PNC Reality Services (Harbor East) Location: Baltimore, MD

As an industry leader in sustainable practices, PNC Bank and Encon continually strive together to create healthy, energy-efficient and productive environments. At PNC Harbor East, there was a unique opportunity to incorporate the prototypical bank branch design objectives – recognizable, accessible and sustainable , within a redeveloped turn-of the-century furniture warehouse, known as The Bagby Building. Located within the context of Baltimore’s hip, new urban neighborhood, the historic character of the site epitomizes the dynamic nature of PNC Harbor East. The design infused salvaged material from the base building renovation with PNC’s standard kit-of-parts to create a welcoming banking environment – both unique and timeless. This project is LEED GOLD Certified.

This was an fun and unique project to work on due to the historical relevance of the Bagby Building and the sustainability component. The design used wood that was re-used from the old building , an old radiator that was cut in two to make a check writing desk, a reused corridor door that was used for a conference room door and the interior brick walls and concrete floor were retained from the original structure.

The World Bank

Client: The World Bank Location: Washington, D.C.

Encon Group as the prime design professional consultant provided mechanical, electrical, and structural engineering services for the replacement of three (3) existing 450 ton R-11 centrifugal with three (3) new 450 R-134A frictionless centrifugal chillers which was completed during the 3rd quarter of 2010.

This project was the second phase of the building’s mechanical plant upgrade which included the replacement of two (2) 2-cell existing cooling towers with four (4) 338 ton new cooling towers which was completed during the second quarter of 2005. As the prime design professional consultant for both projects, Encon Group performed a life cycle cost analysis (LCCA) for two (2) alternate cooling towers and six (6) alternate chillers. The analysis revealed the best selection base on first cost, operating and maintenance costs over the projected equipment life cycle.

Encon Group’s design included a construction phasing plan that would allow for the plant to operate during construction. The design included the replacement of the chilled water and condenser water pumps and converted the plant from a primary/secondary pumping system to the variable primary pumping system. Variable speed drives (VFDs) for the pumps and tower fans, new automatic temperature controls, electrical, and a refrigerant monitoring system were included in the project.

Encon provided construction administration services including shop drawing and request for information (RFI) review and response, site visits, attendance and recording of meeting minutes at construction meetings, punch list reports, review and approval of contractor applications for payment, and review of contractor change order requests. and documentation of as built and operation manuals. At the conclusion of the construction project, Encon Group performed commissioning services for the entire mechanical plant.

We also have Coordination with other design members including architecture, structural, and security. We are proud of our involvement of PNC’s Green (LEED) programs.

Design concepts for PNC Green projects include:

Glass in the windows three times more efficient than conventional glass. Natural “day lighting” in all occupied areas of the building.

Reduced water usage through dual‐flush toilets and low‐flow faucets.

Heating and air conditioning systems that use 35% less energy.

Lighting fixtures and day lighting controls that minimize electricity use.

Roofing material is highly reflective and reduces heat retention; and is supported by trusses and plywood that come from managed forests, which plant multiple trees for each one cut down.

Most everything is made from recycled material from the steel structure to the carpet.

Pre‐manufactured exterior panels reduce construction waste.

Roof projections were designed to shade the building interior from direct sunlight.

Solar shades for windows that block direct sunlight without eliminating daylight.

The paints, adhesives and caulking used during construction do not contribute to greenhouse gases.
