Montgomery College began its green building program in the early 1970s in response to the “energy crisis” and partnered with the Department of Energy in completing energy audits and performing energy conservation retrofits. The College pioneered energy efficient building design when it expanded to its Germantown Campus in the late 1970s and early 1980s by incorporating high performance design features such as efficient envelopes(walls, windows, roof, shading devices) and whole building solar thermal systems as the heat source for high performance water source heat pump systems.
In the mid-1980s, the County Government legislated Building Energy Performance Standards requiring that all new and renovated buildings meet an energy performance budget. In response the College required Architecture/Engineering Design Teams implement requirements of the Energy Design Guidelines by forming an integrated design team, provide an Energy Analyst, perform Energy and Life Cycle Cost Analysis and implement new building technologies such as high performance envelopes, highly efficient HVAC systems, and high efficient lighting and controls. The College led the effort to include requirements for refrigerant management, lighting occupancy sensors, lighting daylight sensors, indoor air quality, commissioning, water conservation, solar energy, heat recovery, hazardous waste management, waste reduction and re-cycling. As a result, many College buildings have received design awards.
In the late 1980s and early 1990s the College performed Utility Master Plans on all three campuses which evaluated the expansion of the campus utility infrastructure to meet projected College growth. The master plans also performed life cycle cost analysis on systems such as centralized vs. decentralized production of heating and chilled water and opportunities for utility demand management. Some recommendations that have been implemented are the use of central chilled water and hot water plants with high performance ammonia refrigerant chillers, ice thermal storage, co-generation/co-process with heat recovery, variable speed pumping, low temperature chilled water distribution, multi-fuel capabilities and high efficiency boilers. During these years the College continued with its energy retrofit programs and received in excess of $750,000 in rebates from the utility companies. A formalized roof survey and replacement program not only improved the thermal roof envelopes but eliminated leaks which is a source of mold and one cause of indoor air contamination All of these efforts resulted in many years of nearly level utility cost, while only recently due to worldwide energy volatility, utility deregulation and expansion of College facilities have costs begun to escalate.
In the late 90s and early 2000s the College renovated the aging solar thermal systems at the Germantown Campus and replaced them with solar photovoltaic electricity generating panels and high performance evacuated tube collectors. On the new Health Sciences Center at the Takoma Park Campus 33 kW of solar photovoltaic panels have been installed.
From the beginning the College has taken its environmental stewardship responsibilities seriously and taken the lead by embracing the evolution of the green building and green campus concepts. The College continues to refine its processes such that green building design and operations is integrated into the fabric of the facilities management team.
Many opportunities remain for example, outreach and coordination with the faculty, staff and students continues to evolve and proves to be an untapped wealth of opportunity. This website is an effort to improve communications and we hope that you will find it useful and worthwhile.
