Dagher Engineering, founded in 2000, is a mechanical and electrical engineering consulting firm. A leader in sustainable design, Dagher Engineering actively promotes programs and designs intended to reduce and reuse energy and water resources. They believe that properly designed, installed, and maintained energy- and water-efficient building systems can both save money and create comfortable working environments.
Dagher Engineering offices are located at 29 Broadway in downtown Manhattan, New York City. Their office space occupies floors 21 and 22 of this 30-story office building. When the firm relocated to the space, they designed and built the new space using the U.S. Green Building Council (USGBC) guidelines for interior spaces. As a first step, Dagher Engineering used the ENERGY STAR Portfolio Manager tool to benchmark the new office. Benchmarking with Portfolio Manager highlighted areas where energy-efficient upgrades could have high impact and based on the results, Dagher planned and implemented their office build-out. The results of their upgrades are impressive: Dagher Engineering offices have an ENERGY STAR rating of 89 and are LEED Gold certified!
Upgrades to the workspace fell into three categories: Energy Efficiency, Sustainable Materials and Indoor Air Quality. The goal was to “go green” without affecting the bottom line.
Dagher chose flooring for the office made from renewable materials (bamboo and linoleum) and used recycled denim insulation. If renewable and/or recycled materials were not available, low or zero Volatile Organic Compounds (VOCs)-emitting materials were applied.
The firm also partnered with owners and co-tenants to benchmark the entire 30-story office building in Portfolio Manager. Because the building was built in 1931, this presented a challenge; it can be difficult retrofit older buildings with modern energy and water efficiencies. With statistics from Portfolio Manager and guidance from Dagher Engineering, the building owners upgraded the chillers and tenants upgraded their individual mechanical, electrical, and plumbing systems. With this dedication, Dagher’s building earned the ENERGY STAR label in 2009.
In addition to using Portfolio Manager for their own office space and building, Dagher Engineering uses it to benchmark both commissioning and retro-commissioning client projects. In New York City, the ability to use Portfolio Manager for retro-commissioning is especially important because many of the buildings are older. Clients are encouraged to continue use of Portfolio Manager as a tool to verify performance after construction is completed.
During the process of building their office space and benchmarking at 29 Broadway, employees at Dagher Engineering became aware that construction professionals had difficulty implementing sustainable designs. To help educate contractors, they developed materials and presentations to teach contractors green building techniques.
