Today’s Handout: Radon, et al (For future dedicated session)

During today’s colloquium we audit the literature that sets the standard of care for mechanical engineering design, construction operations and maintenance of campus district energy systems — typically miles (kilometers) of large underground pipes and wires that characterize a district energy system.  Topically, Mechanical 400 deals with energy systems “outside” or “between” buildings; whereas Mechanical 200 deals with energy systems within an individual building envelope.

A campus district energy system is a centralized heating and cooling network that supplies thermal energy to multiple buildings within a defined area, such as a college or university campus. The system generates steam, hot water, or chilled water at a central plant, which is then distributed through an underground network of pipes to individual buildings for space heating, domestic hot water, and air conditioning. By consolidating energy production and distribution, campus district energy systems can achieve significant energy and cost savings compared to individual building systems, as well as reduce greenhouse gas emissions and improve reliability and resiliency of the energy supply.

It is a large domain and virtually none of the organizations listed above deal with district energy systems outside their own (market-making) circle of influence.  As best we can we try to pull together the peak priorities for the real asset managers and engineers who are responsible for these system.

* Building services engineers are responsible for the design, installation, operation and monitoring of the technical services in buildings (including mechanical, electrical and public health systems, also known as MEP or HVAC), in order to ensure the safe, comfortable and environmentally friendly operation. Building services engineers work closely with other construction professionals such as architects, structural engineers and quantity surveyors. Building services engineers influence the architectural design of building, in particular facades, in relation to energy efficiency and indoor environment, and can integrate local energy production (e.g. façade-integrated photovoltaics) or community-scale energy facilities (e.g. district heating). Building services engineers therefore play an important role in the design and operation of energy-efficient buildings (including green buildings, passive houses and zero energybuildings.  uses. With buildings accounting for about a third of all carbon emissions^] and over a half of the global electricity demand, building services engineers play an important role in the move to a low-carbon society, hence mitigate global warming.
