Building Enclosure

All exposed exterior columns are to be constructed to meet Class A concrete industry standards. Exterior concrete walls above grade are to be constructed to meet Class B Concrete industry standards. This concrete is to receive a medium sandblast to remove formwork marks. Formwork ties must be removed, round impressions may remain. Top of a wall is to be ground smooth to create a level and consistent edge and finish. Provide sandblasted finish to all exposed exterior concrete flooring/decking not specified in the landscape drawings. Fly ash is to be used in all concrete mix per the structural engineer’s specifications.

Stone Veneer is to be Pennsylvania Blue Stone Veneer
o Stone to be sawcut and smooth
o Stone to 2” thick, 8” tall, and average 48” in length, varying from 24” to 72”

Terra Cotta exterior rain screen paneling to be TerraClad System by Boston Valley. The façade uses 12” x 60” smooth panels.

The building interior will blur the lines between interior and exterior to create an environment that comes alive through its use of diverse natural materials, visual connection to the exterior and by allowing natural light to filter through the building.

Sustainability Features

--100% of the condensate, roof-harvested rainwater, and foundation groundwater will be collected and used for irrigation and toilet-flushing, as well as chiller makeup. A series of bio-swales will be introduced to naturally filter water and to allow it to infiltrate the adjacent soils prior to being introduced into the watershed.

--The biophilic design will enhance human health and happiness by celebrating our innate human attraction to natural systems and elements.

  1. Views to outside

  2. Ample daylight & fresh air

  3. Natural materials & patterns, natural shapes & forms

  4. Healthy materials, avoiding an established “red list”

  5. Comfortable spaces, indoors & outdoors.

Structural System

The materials used in the system includes cement, aggregates, admixtures, concrete, reinforcement, steel, and masonry were chosen by the ASTM standards and design stresses. The framing system for this building design is a conventional cast-in-place concrete two-way flat slab system. This concrete system provides a robust and flexible solution in a classroom/laboratory environment; allows for a reduced structural depth, provides an inherent fire rating, allows for simpler and cost-effective integration and maintenance of other building systems. Lateral loads, wind and seismic, will be resisted by the column and slab frame. No need for shear walls. Concrete moment frames result in a flexible long-term solution. There are two large auditorium type classrooms that will require a column-free space. Spread footing system founded on compacted aggregate piers was designed for an allowable composite bearing pressure of about 6,000 to 8,000 psi.

The strength of the concrete is 4500 psi for exterior and 3000 psi for interior due to different load bearings. The foundation wall system consists of 4500 psi concrete, and the framing system includes columns with a strength range of 4500 to 5000 psi, SOG of 3500 psi, floor framings of 5000 psi

Electrical

Primary electric service at 15kV voltage class will be derived from PEPCO from an existing manhole to the north or southeast of the project site and run to two or possibly three PEPCO-owned, pad-mounted transformers. PEPCO has indicated that they will provide secondary service at 480Y/277V, likely from two or three transformers, connected to a single medium-voltage feeder. Service entrance equipment will be designed to PEPCO standards. Busses will be copper.

Plumbing

Isolation valves will be provided to facilitate maintenance at each lab space, a group of toilet rooms, program suite, or at other branches where routine service shall be required. All isolation valves will be accessible and located on the floor being served, or in the interstitial space serving the respective program area. Sanitary waste from toilet rooms, service sinks, showers, drinking fountains, general use mechanical equipment will be conveyed by gravity, tied together in the basement and routed to discharge from the building. Flow rates and pipe sizes were calculated based on drainage fixture unit values (per IPC 2012) and adjusted/increased to allow for projected wastewater discharge from various mechanical equipment at the design stage, plus 20% for future expansion

Mechanical

Ten (10) LEED points are anticipated to be achieved through energy use reductions by the systems specified and through the optimization of their operation. One LEED point is anticipated to be achieved through the measurement and verification of energy use upon activation of the building. Multiple meters will be required for all utilities for sub-metering per LEED. One LEED point is anticipated by using CO2 sensors (and perhaps other types) to regulate indoor air quality. This will be accomplished through continual comparison between indoor CO2 (and perhaps other contaminants) levels and outdoor levels of the same and in turn modulation of outside air systems.

Lighting System

A complete lighting system for all indoor and outdoor illumination will be provided. The indoor lighting system will consist primarily of energy-efficient fixtures selected by the Lighting Consultant. The outdoor lighting system will consist of fixtures selected by the Landscape Architect. Light fixtures in “back of house” spaces will be primarily high-efficiency LED fixtures. In general, indoor lighting controls will consist of room occupancy sensors and line voltage switches and ambient light sensors. Outdoor lighting controls will utilize photocells and time switches with line voltage manual override switches. Emergency/night lighting will be provided by unswitched branch circuits. These unswitched branch circuits will be fed from an emergency lighting panel.
