School buildings in general host many activities that require special mechanical and electrical system design considerations. Due to the high occupant density load, the need for air handing systems with high percentage of outdoor air (above 30%) can be found in several areas in educational facilities, in order to prevent indoor air quality problems and conserve energy. Among other special requirements such as: lighting, power, and demand control ventilation, classrooms require humidity control to provide comfort and prevent humidity related issues, in fact low humidity, favors longevity of infectious viruses, and therefore their transmission between occupants.
Health Care & Institutional
Continual advances in medicine and technology necessitate constant re-evaluation of the Mechanical and Electrical Systems needs for hospitals and institutional facilities. Research evidence shows that, proper HVAC is helpful in preventing and treating many conditions, when ventilation requirements exist to protect against harmful occupational exposures.
Studies have shown that 30 to 40 percent of healthcare facilities total energy use can be caulked up to the HVAC system – the steam chilled-hot water plant, and air distribution.
When operations run 24/7, the opportunities for savings are constant. Smart practices can cut energy use and related costs in half.
Energy conservation codes and standards must be considered because they have a major impact on design and performance. High energy costs and consequent environmental damage requires that these types of facilities be energy efficient and sustainable. Occupants need insurance that they can afford the fuel bills and that their lifestyle is not damaging the planet.
Office Building & R&D
Office buildings are considered the most complex and competitive segments of real estate development. Office buildings can be single tenant or multi-tenant. A single tenant building can be owned by the tenant or leased by the landlord. From a mechanical and electrical system standpoint, a single tenant/owner is more cautious considering issues such as life cycle cost and energy conservation. In many cases, the systems are not selected based on the lowest first cost but on a life-cycle cost. Sometimes the Mechanical and Electrical Systems are selected in order to allow individual tenants to pay directly for the energy they consume.
Restaurant & Food Service
The Mechanical and Electrical system selection and design for retail and food facilities are normally determined by economics. First cost is usually the determining factor for small stores or restaurants. For large facilities, owning, operation and maintenance costs are also considered. Decisions about mechanical and electrical system for retail and food facilities are typically based on a cash flow analysis rather than a full life cycle analysis.
