GREENHOUSE AT PARK ROW
The Greenhouse at Park Row project is located at 2051 Greenhouse Rd., Houston, TX 77084 and includes
a three story 120,000 sf office building and associated site improvements. D’Agostino Companies seeks
with every development to provide world class facilities, which are able to be tailored to suit a tenant’s
specific needs. As part of this effort, the Greenhouse at Park Row project elected to seek LEED
certification under the LEED-CS 2009 requirements. The project is estimating to achieve 43 points,
earning it “Certified” level certification.
In order to promote the environmental aspects of the building throughout the community, tours will be
conducted for groups and individual representatives of corporations, and individuals interested in LEED
amongst others. Tours can be scheduled during business hours (typically 8a.m. – 5p.m.) on weekdays.
Tours are to be scheduled by contacting the D’Agostino Companies office. For scheduled tours,
designated members of the developer’s team will help guide attendees through the tour highlights listed
in this document.
A brochure highlighting some of the LEED features of the Greenhouse at Park Row project are provided
to each visitor attending the tour. In addition, the brochure is available electronically by visiting
www.dagostinocompanies.com and in the building lobby on the directory monitor for daily visitors.

Open space has been maximized by providing vegetative cover greater than the building footprint.
A storm water quality control feature, or storm trooper, has been installed to remove suspended
solids.
Reduction in the heat island effect by using new white concrete instead of asphalt and highly
reflective roofing material, resulting in radiant reflection therefore reducing radiant heat
absorption.
Increase water use efficiency by installing low flow fixtures in restrooms and by reducing water
required for irrigation through plant selection, and use of efficient controllers and spray heads.
All lighting is low energy (LED and fluorescent) and is controlled through a lighting control panel
to minimize energy use.
Optimized energy performance of the building through improving the envelope of the building by
insulating the roof and exterior walls, and installing HVAC (heating, ventilation, and air
conditioning) that outperforms current energy codes.
Selection of refrigerant for the HVAC system that does not contain any CFC (chlorofluorocarbon)
based refrigerants.
70% of the building’s common area power is purchased as Green Power.
An area for recycling containers for use by building occupants has been designated within the
lobby. Recycling is focused on materials such as paper, corrugated cardboard, plastics, glass and
aluminum.
Waste generated during construction is planned to be reduced to 75% by the diversion of waste
from the landfill through segregation of the waste stream.

All elements used in the project, outside of those in the MEP systems, contain at least 20%
recycled content by cost. They were also extracted, harvested or recovered, and manufactured
within 500 miles of the jobsite.
Permanently installed wood products are Forest Stewardship Council Certified.
Greenhouse at Park Row is a non-smoking building. Smoking allowed only 25’ away from the
building entrances.
Improved ventilation systems and thermal comfort to improve indoor air quality, occupant
comfort, well-being and productivity.
Increase indoor air quality for occupants by using low VOC (volatile organic compounds) carpet,
paint, adhesive, sealant and composite wood.
The HVAC system is computer controlled to maximize energy efficiency and occupant comfort.
The control system is expandable to allow future tenants to fully control their spaces as well.
All windows are 1” insulated glass panels with a low –e coating to decrease heat gain while
allowing maximum view.
