C.L.I. Group
evaluates each building by looking at the building as a whole system. Buildings are made up of many integral components which operate as a whole to make buildings safe, energy efficient and comfortable for the occupants. We evaluate each building and building component with this in mind. All too often, contractors & sub-contractors, inspectors and others overlook this fact with less than satisfactory results. For example, updating an older building by adding insulation, new windows, adding walls, etc. may create new problems such as depleting needed combustion air, changing building pressures and causing combustion gases to backdraft into the building. Changing building pressures and/or natural infiltration rates can also lead to inadequate fresh air ventilation, indoor air quality issues, moisture and condensation issues and other conditions which should be understood when undertaking such modifications. The same is true in commercial buildings. Is the building being used as it was originally designed? Have modifications been made such a splitting large, open areas into offices? Was the HVAC system updated and balanced to accommodate any such changes? These factors can all affect  the building and the occupants of the building and should be evaluated during renovations.
