After evaluating the existing HVAC systems to determine causes for the system’s inability to maintain desirable environmental conditions, MMM recommended corrective action with construction schedules and estimated costs. The existing builiding is to be provided a new exterior skin and glass with construction documents prepared by a separate design package. MMM prepared annual energy analysis and life cycle cost analysis on multiple types of building materials, insulation and glass, and recommendations.

This analysis was prepared in-house on a PC-based Hourly Analysis Program (HAP 3.0). Existing HVAC equipment capacities were compared to the heating and cooling loads for each façade studied. By adding a slight amount of wall insulation, MMM was able to retain the central heating and cooling equipment that was otherwise undersized.
