HARVARD UNIVERSITY LEED-NC V3
HARVARD BUSINESS SCHOOL—DEAN’S HOUSE LEED SILVER
51 Harvard Way, Boston, MA 02163
This project encompassed the renovation of the Dean’s Residence located on the Harvard Business School
(HBS) campus in Boston. It consists of a four story structure with a total area of 11,000 square feet. The
purpose of this project was to correct numerous deferred maintenance issues and to make space alterations
and interior updates to prepare the Dean’s House for occupancy by the new HBS Dean and his family as well
as provide space for hosting social functions and events for HBS. The original facility was constructed in 1929
but was last occupied as a residence in the 1970s. The 82-year old brick masonry building had an exterior
upgrade completed in 2008. At that time only the kitchen was upgraded to replace flooring, cabinets, and
appliances in the interior of the building.
Prior to 2008, the last major renovation to the house occurred
in the early 80’s, but many of the major systems were not
touched. As a result there were significant deferred
maintenance issues that warranted addressing. These issues
involved all the major building systems – heating, ventilation
and air conditioning, electrical primary feeds, transformers
and panel distribution, fire alarm system expansion, and the
addition of sprinklers to the boiler room. Many of these
systems were well over 30 years old and had reached the end
of their useful life expectancy.
The facility now serves as a model for updating a historic
building to contemporary standards of sustainability and
resource conservation while highlighting Harvard Business
School’s commitment to the environment.

Located in the heart of the Harvard
Business School campus in Allston,
this building is well connected to many
basic services that can be accessed
via walking or biking.
The house is within a quarter mile of
both Harvard University campus and
MBTA bus lines.
Bike storage is ample and well pro-
tected from the environment, including
both a covered storage shed in the ex-
terior grounds and dedicated areas in
the garage.
The site is well landscaped, shading
much of the site hardscape and the
building itself, both of which help to
reduce cooling loads in the summer
heat.

FFICIENCY
The Harvard Business School has committed, along with Harvard University as a whole, to reduce greenhouse gas emis-
sions 30% below 2006 levels by 2016, inclusive of growth. Therefore energy efficiency was a main goal of this renovation
project.
E
LECTRICAL
S
YSTEMS
ECM 1: Low Power Lighting—Using the ASHRAE 90.1-
2007 ―Space by Space‖ lighting calculation method, the
Dean’s House lighting power density of 0.92 W/sf
outperforms the baseline by 18%.
ECM 2: Occupancy Controlled Lighting—Similar to
ECM4 in the Mechanical Systems section, the same
occupancy sensors will also regulate whether power is
supplied to lighting in each space, further reducing
electricity consumption.
ECM 3: Variable Frequency Drive (VFD) on HVAC
Pump—The primary pumps controlling the heating hot
water service can modulate to meet the aggregate demand
of each space, reducing energy consumption while
providing increased comfort to the building.
M
ECHANICAL
S
YSTEMS
ECM 1: Natural Ventilation—Most of the spaces at the
Dean’s House contain large operable windows that meet
ASHRAE 62.1 requirements for naturally ventilated space
and help to reduce consumption costs associated with
mechanical ventilation systems.
ECM 3: Increased Insulation—The insulation values for
all components of the building envelope significantly
exceed what is required by code, resulting in lower heating
and cooling loads than what would be encountered
otherwise.
ECM 3: Outdoor Air Temperature Resets—The boilers
supplying heating for the house reduce their temperature
setpoints based on the outdoor air temperature (OAT),
increasing the supply temperature as OAT decreases.
ECM 4: Occupancy-Based HVAC Controls—Fan coil
units in the Dean’s House will operate in conjunction with
occupancy sensors in each space to enable setbacks
whenever people are not currently using a room. This will
significantly reduce the need for heating and cooling in
certain event spaces and guest rooms.

The Harvard Business School 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. Through the use of low VOC products, the Dean’s House satisfied all LEED
requirements for low emitting paints, adhesives and sealants.
