DESCRIPTION OF SHELL CONDITION SCHEMATIC DESIGN ARCHITECTURAL OUTLINE DESCRIPTION TOWN CENTRE ONE – KIRKSEY PROJECT #2012066 700 Town & Country Boulevard Houston, TX 77024 I. GENERAL The project site is 4.493 acres located on the corner of the Town & Country Boulevard and Queensbury Lane. The project consists of a 10-story office building, a 2-story theatre building and an 8-story parking garage and associated site and utility work. The office building contains approximately 256,000 BOMA net rentable square feet. The theatre building is approximately 19,750 square feet of gross square footage. The parking garage contains approximately 1,370 parking spaces. The building does not include a basement with the first floor being at grade level. The main mechanical, electrical, fire protection systems and back-of-house services will be located primarily at the first floor. The roof penthouse will house HVAC equipment as well. The existing site is covered by impervious surfaces and therefore, site storm water detention is not anticipated. The project is designed in accordance with the requirements of the 2006 International Building Code, with Houston amendments, and 2012 Texas Accessibility Standards. The office tower construction is Type IA, fully sprinklered, and the garage construction is Type IA, open, not sprinklered. The proposed level of U.S. Green Building Council L.E.E.D. rating is Silver. II. BUILDING CORE AND SHELL, SYSTEMS AND FINISHES a.

BUILDING DESIGN The building is designed for 10 stories with the typical floor plate providing approximately 26,000 NRA. The first and second floors are smaller to accommodate overhangs along the west façade to provide pedestrian access. A Registered Accessibility Specialist (RAS) has been contracted to assist the Architect review, identify and resolve any compliance issues related to T.A.S., A.D.A. or other accessibility issues. The Architect’s in-house LEED consultants have reviewed and advised the A/E team with respect to applicable credits. The building, as designed, will achieve a LEED Silver certification without negatively impacting the development budget. Additional credits were considered to achieve LEED Gold certification, but were not feasible due to project type and location. Landlord shall incorporate into the Building design requirements necessary for Tenant to LEED certify their interiors construction, such as minimum energy and Indoor Air Quality performance standards, collection and storage of recyclables, etc. document1. The building is designed to be 20% better in energy efficiency than a similar building built to City Code. Energy efficiency measures include variable speed chillers, increased part load efficiency due to pony chiller, Supply air temperature resets, VFD on all fans, Demand control ventilation, efficient lighting in garage with daylight harvesting. An M&V Plan is proposed for the Base building and another for tenant space for occupants to track their energy usage. The office floor plate is designed to have sufficient daylight in 75% or more spaces and with outside views in 90% or more spaces. The Visual Light Transmittance (VLT) used in the building's glazing is between 30% to 73% while their Solar Heat Gain Coefficient (SHGC) is between 0.23 to 0.39. Low-emitting materials will be used throughout the building in order to help ensure healthy indoor air quality. In addition, an indoor air quality management plan will be implemented during construction to minimize the amount of pollutants and particulate matter that will enter the building or remain in the space. At least 50% of the wood on the project (by cost) will be Forest Stewardship Council-certified, ensuring that it has come from sustainably harvested forests. Materials in common areas such as lobbies and restrooms will be commercial grade, generally nonporous and in a finish that will facilitate maintenance and cleaning.
