I. Introduction and Principles
A. Commitment to Environmental Stewardship
The Mount Holyoke College Plan for 2003 called upon the College community to “improve environmental literacy and awareness, generate scientific knowledge, guide public policy, and encourage students, faculty and staff to advocate and effect social change to improve the environmental health of our community and our world.” While making continual progress toward that goal, the Mount Holyoke College Plan for 2010 calls upon us to “accelerate our progress toward systematic practice of environmental stewardship, providing an excellent example of synergy between curricular and administrative efforts and a clear focus on cost-effective applications of environmentally responsible principles.”
As evidence of that commitment, MHC received certification under the USGBC’s Leadership in Energy and Environmental Design (LEEDTM) Green Building Rating System, for the Science Center and Blanchard Campus Center. The Science Center, completed in the fall of 2003, is one of the nation’s first LEED-certified science centers. In fact, the Science Center and Blanchard, a turn-of-the-century building that reopened in September 2003 after reconstruction and renovation, were among the first nine projects registered for LEED certification.
Subsequent to the completion of those two LEED certified buildings, the College established a Green Building Design and Construction Working Group tasked with making recommendations on the future implementation of green building design and construction principles on campus. The Group has recommended that Mount Holyoke define campus Environmentally Responsible Building Principles and Guidelines.
While achieving LEED certification is not precluded for major projects, it is generally not achievable for smaller renovation projects. Campus standards will allow for application of the Principles and Guidelines to all construction and renovation projects on campus. For those instances when a decision to achieve LEED certification is made, the LEED section appropriate to the guideline is listed parenthetically.
B. Environmentally Responsible Building Principles
Green building design has both an environmental and economic sustainability component. The College is committed to environmental stewardship including construction of green buildings, however, design choices must be made in light of the ability of the College to finance the project. The following Environmentally Responsible Building Principles serve as a guide in decision making during building siting, design, construction, and operation. MHC Environmentally Responsible Performance Guidelines detail siting, design and construction requirements to meet these Principles.
- Site and design the building to minimize long-term environmental impact and operate the building to maximize the benefit of the environmental design elements.
- Design and construct the building to minimize the impact on the natural environment of the site and the campus.
- Optimize use of passive energy strategies to make the most of natural lighting, heating, cooling and shading to complement mechanical systems.
- Design mechanical lighting, heating and cooling systems to minimize energy use and emission of greenhouse gases.
- Create a comfortable and healthy indoor environment.
- Minimize potable water use by mechanical systems, building occupants, and for exterior landscaping.
- Minimize and control water runoff from the site to prevent degradation of Stony Brook and Upper and Lower Lakes.
- Use building materials that minimize the life cycle environmental impact of those materials. Minimize waste generation during the construction process and maximize reuse and recycling.
The following principles apply to the design process.
- Introduce environmental responsibility early in the planning process.
- Hire architects, engineers, and construction managers with experience in environmental design and construction and work collaboratively to achieve project goals.
- Use life cycle costing to evaluate building cost.
- Use building commissioning to evaluate systems and ensure performance standards are met.
C. Setting Goals
This document serves as a set of Guidelines to be used in the design and construction phase of construction and renovation projects on campus. While it may not be feasible to achieve all of the aspirations included in the Guidelines, the project review process established will establish goals for each project and measure performance against the Guidelines and individual project goals. These Guidelines are in addition to all legal obligations under local, state and federal codes and regulations. The Guidelines will be reviewed at least annually to determine if it is an effective tool in support of Mount Holyoke’s Environmentally Responsible Building Principles.
II. Environmentally Responsible Green Building Design Guidelines
A. Site Selection and Stewardship
Principle: Site and design the building to minimize long-term environmental impact and operate the building to maximize the benefit of the environmental design elements.
Principle: Construct the building to minimize the impact on the natural environment of the site and the campus.
Principle: Minimize and control water runoff from the site to prevent degradation of Stony Brook and Upper and Lower Lakes.
A.1.0 Site Selection
1.1 Development Area
- Select sites without sensitive natural features and restricted land uses.
- Give preference to sites with existing building space or in developed areas of campus.
- Restrict development to areas with existing infrastructure to protect undeveloped areas, and preserve habitat and natural resources.
- Locate buildings and plantings so that deciduous trees block summer sun to the south and west, and evergreens block winter wind.
A.2.0 Site Analysis and Development
2.1 Resource Conservation
- Determine whether or not inventories or analyses of natural (e.g., microclimate characteristics, habitats) or cultural (e.g., archeological) site features are needed to ensure that the project will achieve environmental goals and not have unanticipated impacts.
- Map sun and shade patterns, and ground level wind patterns associated with new construction.
- Conserve existing natural areas and restore degraded areas to provide habitat and maintain diversity.
- Minimize impact on existing hydrological features (e.g., streams, lakes, wetlands, groundwater).
2.2 Site Access and Transportation and Parking
- Promote walking and bicycling and provide safe routes, including extending sidewalks to the end of campus, and supporting landscape features (e.g., paths, seating).
- Provide bicycle racks and evaluate need for changing rooms.
- Encourage use of public transportation by locating buildings a convenient distance from bus stops or evaluating the need for bus route changes.
- Avoid creation of additional parking spaces on campus and minimize parking lot size.
2.3 Building Footprint and Utility Placement
- Minimize the building footprint and other impervious surfaces to minimize site disruption and stormwater runoff.
- Cluster underground utilities running in conduits using shared-trench technology where feasible.
- Locate underground utilities in roadways or fire lanes, to minimize site disturbance.
2.4 Stormwater Runoff Generation and Management
- Maintain natural stormwater flows by designing the project site to promote infiltration and respect natural drainage patterns.
- Minimize program needs for paved surfaces such as sidewalks and roadways.
- Minimize stormwater runoff from impervious surfaces through use of groundwater recharge, porous paving materials, garden roofs or other techniques; consider overflow areas that use turf or other low impact material.
- Use natural runoff control and treatment systems such as bioswales. If natural methods are not feasible capture all runoff from impervious surfaces and treat prior to discharge.
- Reuse stormwater for non-potable uses such as landscape irrigation.
- Hold slopes in place with biotechnical erosion controls (e.g., organic mulch/tackifier combinations).
- Use greenwall technology (incorporating plantings) instead of hardscape for retaining walls.
- Use planted buffers to direct grading and drainage.
2.5 Reducing Heat-Island Effect
- Design planting to maximize shade on the site’s non-roof impervious surfaces.
- Utilize technologies that reduce heat absorption (such as high albedo paving).
2.6 Utilize Sustainable Landscape Practices
- Select plants that are native or adapted to the site’s microclimate. Stress plant diversity and avoid monoculture planting. Do not use invasive or potentially invasive plants.
- Avoid the use of plant species that are high maintenance and have significant pest problems.
- If possible, orient plants in the same direction they grew in the nursery.
- Choose plants with water requirements that can be met by natural precipitation patterns. When irrigating is unavoidable, use soaker hoses, or other methods that minimize water loss.
2.7 Improve Soil Quality
- Analyze planting soil and improve as needed.
- Implement soil remediation measures as needed for the site such as introducing earthworms if they are sparse, adding organic matter and microorganisms to break down pollutants, and removing toxic materials.
- Mulch plant beds to conserve soil moisture, and improve soil fertility and structure.
- Use compost from on-campus sources when possible; do not use peat moss to amend soil since it is a non-renewable resource.
- Compost any green waste from the site for use on campus.
2.8 Select Appropriate Materials For Landscaping Features
- Use recycled, renewable, salvaged, and/or locally sourced materials when constructing landscaping features.
- Consider using rapidly renewable materials, such as bamboo, which has been harvested using sustainable practices.

IV. Deliverables
A. Pre-Design
Principle: Introduce environmental responsibility early in the planning process.
Principle: Hire architects, engineers, and construction managers with experience in environmental design and construction and work collaboratively to achieve project goals.
A.1.0 Green Strategies Workshop
On projects of any significant size at Mount Holyoke College, a multi-disciplinary kick-off workshop shall be held. Purpose of the Workshop will be to create a road map for the project team to follow. This goal setting Workshop will identify green strategies and performance targets for this particular project. Also, it will be determined if formal certification will be sought for the project. Recognizing that good green design comes from a team driven approach, designers from all disciplines will be expected to participate in the kick-off Workshop – landscape, civil, electrical, mechanical, plumbing, architectural, interiors, etc.
A.2.0 Performance Plan
Based on the Workshop, the Design team will be responsible for a delivering a “Performance Plan” which summarizes all environmental and energy performance targets for the project, together with the strategies elected from this guideline to meet those benchmarks. Performance Plan shall consist of two parts:
- A narrative of the design intent
- A checklist of goals and strategies being considered for the project. The Design Team shall prepare the Performance Plan.
B. Design
Principle: Use life cycle costing to evaluate building cost.
B.1.0 Performance Plan Updates
During design, the Design Team shall be responsible for updating the Performance Plan so that it comprises a record of design intent and decision-making with respect to energy and environmental principles. Using the Performance Plan, the Design Team will provide explanatory notes for changes in strategies and deviation from performance targets and effectively justify non-compliance with the original performance targets.
B.2.0 Submittals
