The project involved an extensive renovation that combined 641-643 Huntington Avenue.

Additional site improvements were made to the exterior of the building, which include new paving and landscaping.

A new 8-stop elevator was installed, while new mechanical, electrical, plumbing and fire protection systems were added throughout.

1 BOSTON, MA LEED NCV2.2 Completed in August 2009, is a 25,000 square foot building in Boston Massachusetts, used as office and meeting space by the Department of Social Medicine within the Harvard Medical School (HMS). The project involved an extensive renovation that combined Huntington Avenue. The wood framed masonry façade was fully restored with new windows, and a comprehensive upgrade to the entire roofing system was undergone. Additional site improvements were made to the exterior of the building, which include new paving and landscaping. The interior of the building received a complete fit-out to all of the existing office spaces. A new 8-stop elevator was installed, while new mechanical, electrical, plumbing and fire protection systems were added throughout. In support of Harvard s goal to reduce greenhouse gas emissions 30% below 2006 levels by 2016, inclusive of growth, HMS and the project team were committed to sustainability throughout the duration of the project. This helped to guide decision making and inform the selection of materials, as well as the mechanical, electrical and plumbing (MEP) systems. Ultimately, 641 Huntington Avenue was awarded a LEED Gold Certification under the LEED for New Construction version 2.2 (LEED-NC) rating system. PROJECT HIGHLIGHTS Lobby Photo: G.

ENERGY EFFICIENCY Harvard Medical School (HMS) has committed, along with Harvard University as a whole, to reduce greenhouse gas emissions 30% below 2006 levels by 2016, inclusive of growth.

This model shows that the building should consume 36% less energy than the base case, saving nearly 29,886 kwhs of electricity and 3,920 therms of gas every year.

4 ENERGY EFFICIENCY Harvard Medical School (HMS) has committed, along with Harvard University as a whole, to reduce greenhouse gas emissions 30% below 2006 levels by 2016, inclusive of growth. Therefore, energy efficiency was a main focus. An energy model completed for the building compares the design to a minimum code-compliant base case. This model shows that the building should consume 36% less energy than the base case, saving nearly 29,886 kwhs of electricity and 3,920 therms of gas every year. These reductions will save $47,286 in utility costs yearly, and reduce greenhouse gas emissions by 572 metric tons of carbon dioxide equivalent (MTCDE) over the 20 year expected life of equipment. MECHANICAL SYSTEMS Enthalpy Wheel Energy Recovery: Exhaust air is run through a heat recovery (enthalpy) wheel, which transfers both heat and moisture to incoming fresh air, reducing the amount of energy needed to condition the air by up to 75%. Demand Control Ventilation: CO 2 sensors in all high density spaces control the amount of outdoor air supplied. If there are fewer people occupying the space then less air is required, ultimately saving energy. Occupancy and Temperature Sensors: Occupancy sensors tied to the building s control system modulate the supply air and maintain temperature set-points, allowing both to be set back whenever spaces are unoccupied. Condensing Boiler: The gas fired boiler is an 88% efficient condensing-type boiler, meaning that heat is recovered from the flue gasses before they are exhausted This is 10% more efficient that the code complaint base case. High Efficiency Chiller: The York high efficiency air cooled chiller has a Coefficient of Performance of 2.8, which is 3% more efficient than the base case. Premium Efficiency Pumps: All new pumps are rated by NEMA to be premium efficiency. Pumps that distribute hot water have variable frequency drives, further reducing energy consumption when full load is not required. Commissioning: The mechanical and electrical systems have been fully commissioned, ensuring that all energyrelated systems were installed as designed and operate efficiently prior to occupancy. Renewable Energy: Renewable Energy Certificates (RECs) were purchased from Sterling Planet (wind power) equivalent to 70% of the anticipated electricity over 2 years. Enthalpy Wheel Diagram Uptime Technology BV BUILDING ENVELOPE Windows: Energy Star certified windows provide a high insulating value and a low solar heat gain co-efficient. The windows have a U-value of Walls & Roof: Icynene foam insulation was provides greatly improved insulating values and reducing air filtration. The walls now have an overall R-value of ELECTRICAL SYSTEMS Icynene & Energy Star Window Photo: Jesse Foote, 2009 Real-Time Utility Displays: Energy consumption is measured in real time by smart meters and the computer based building management system. This information is displayed on a webpage as well as in the lobby of the building, informing occupants about energy use and encouraging them to conserve. Lighting Controls: A digital addressable lighting interface (DALI) system allows for sweep controls, time of day control, daylight harvesting, off hours zone control, occupancy sensors and dimming. Lighting Fixtures: Energy-efficient and lowmercury fluorescent lamps were carefully chosen and strategically placed to reduce electricity consumption while maintaining adequate lighting levels for each type of space. Plug Loads: Energy Star equipment was selected for all new equipment in the space. HMS Real-time Utility Webpage 4

INDOOR ENVIRONMENTAL QUALITY HMS is committed to providing a healthy indoor environment for all occupants.

Indoor Air Quality During Construction: A comprehensive indoor air quality management plan was implemented during construction to maintain healthy indoor air quality for workers and future occupants.

Fans were used to exhaust air directly to the outdoors, and building materials were kept sealed and off the grounds until they were installed.

The Operations team will adjust the heating or cooling in the project space as needed. Only Materials with Low or No VOC Content were used in.

5 INDOOR ENVIRONMENTAL QUALITY HMS is committed to providing a healthy indoor environment for all occupants. The project team was careful to maintain healthy indoor air quality during construction and to also ensure the space is designed to promote healthy indoor air quality during occupancy. Indoor Air Quality During Construction: A comprehensive indoor air quality management plan was implemented during construction to maintain healthy indoor air quality for workers and future occupants. All grills and vents were sealed and ductwork remained sealed until it was installed and covered. Fans were used to exhaust air directly to the outdoors, and building materials were kept sealed and off the grounds until they were installed. Construction IAQ Measures Implemented During Construction Photos: Harvard Office for Sustainability Thermal Comfort Survey: Occupants will be surveyed about their thermal comfort once per season. The Operations team will adjust the heating or cooling in the project space as needed. Only Materials with Low or No VOC Content were used in. Volatile Organic Compounds (VOCs) are chemical compounds and known carcinogens found in many construction materials that are considered detrimental to indoor air quality. Reducing the use of VOCs whenever possible improves indoor air quality and consequently occupant health and productivity. Composite Wood and Laminate Adhesives used have no added Urea Formaldehyde.

Green Housekeeping: The Harvard Medical School custodial department has made a commitment to using green cleaning processes in all of its buildings, including. This includes the use of Green Seal certified cleaning solutions, 100% recycled content toilet tissue and paper towels, portion control chemical dispensers, staff training.
