Housing construction and mistakes


1. Poor access to above-ceiling additives. Poor get admission to frequently yields negative upkeep of building systems. Equipment, valves, disconnect switches, and dampers often are placed above ceilings in locations that are not on hand to the constructing operations and renovation group of workers. Resolution of these troubles not only encourages better maintenance of the constructing structures, however additionally reduces hazard of damage to facility staff seeking to attain components in tough places.

2. Insufficient get right of entry to panels supplied. System components placed above tough ceilings have to be accessible. Resolving instances where an get right of entry to panel has not been supplied, is insufficient in size, or is blocked by means of cabinetry or different permanent objects including millwork or fixtures is extremely vital.


3. Duct insulation vapor barrier this is damaged. Often, a vapor barrier surrounding duct insulation is broken or unsealed during set up. These openings within the vapor barrier permit warm air to condense at the bloodless ductwork, yielding moisture that damages duct insulation and constructing materials under the duct.

4. Insufficient space to allow full thickness of duct insulation. Spaces among duct additives and adjacent piping, building shape, or different duct additives are often inadequate for the entire required intensity of duct insulation. Compressed duct insulation now not most effective contributes to terrible strength performance however can also harm building substances under due to condensation because of the decreased R value of the compressed insulation.

5. Duct insulation that is not continuous. Duct insulation that isn’t non-stop via partitions (non-fire-rated) is a frequent difficulty. This permits heat air to condense at the exposed duct phase within the wall. This condensation then damages adjoining drywall, insulation, and finishes even as also contributing to energy loss thru the uninsulated location. Situations like this are also high applicants for mildew and mildew formation because the results of condensation are regularly hidden inside the partition and aren’t noticed fast.

6. Piping not insulated. Similar to duct insulation, piping is likewise frequently found to be uninsulated. This allows heat air to condense on cool piping, contributing to harm of adjacent materials, and causing pointless electricity loss via the uninsulated place on each warm- and bloodless-water piping.

7. Mechanical controls troubles. It’s fairly not unusual, whilst a commissioning agent begins checking out, to discover that mechanical equipment does now not respond to controls, does not operate in a particular mode, and has no longer been optimized for long-time period operation.

8. Lighting controls tuning. Lighting controls problems also are very commonplace. These include occupancy controls that don’t deactivate lights on the right time and daylighting controls which can be improperly calibrated and over-illuminate the spaces that they serve.

9. Moisture intrusion via windows. During commissioning checking out of windows in the constructing envelope, commissioning retailers frequently become aware of systemic troubles in window installations. These problems permit moisture intrusion into the building that results in material harm and conditions promoting mildew and mold formation.

10. Moisture intrusion thru roof. Observations throughout set up and testing of finished roofs often pick out improperly installed roofing materials and roof drain bodies that permit moisture intrusion via the roof so as to additionally harm materials and sell mildew and mould formation.
