With temperatures on the rise, this time of year can put a significant burden on a building’s HVAC load and the electric grid. Here are four key considerations for AEC firms as we move into the warmer season.
1. Make Time for Preventative Maintenance
Schedule performance checks of forced-air or central air conditioning and ventilation systems before summer. The first few days of heavy use can put too much strain on poorly maintained air conditioning systems. The result is system downtime at the first sign of hot weather.
Now is also the time for AEC firms to replace dirty filters or fans, check belts, fix air leaks, clean condenser coils, etc. When not properly maintained, these items can make HVAC systems work harder. Overstrained systems can create air quality issues and increased energy expenses.
2. Avoid Overcooling
In warmer months, building occupants usually wear light clothing so overly cooled indoor air can lead to complaints. The ambient indoor temperature should ideally be in the range of 74–78 degrees. Another benefit to keeping the temperature high is a 1–3% energy saving for each degree the thermostat is set above 72 degrees.
3. Reduce Relative Humidity
Increased temperatures and humidity can promote the growth of mold and mildew. To avoid this, AEC firms should maintain humidity below 50% in warmer months. Also inspect HVAC systems for mold and moisture. Drain and condensate pans should be draining properly, and HVAC ducts and system components should be kept dry.
In buildings where summer usage drops off drastically, such as in schools, HVAC systems should be put into “unoccupied mode.” That way, the system still operates but only as needed. Keeping HVAC systems running at a reduced level will maintain optimal humidity levels while reducing run time. This helps extend equipment life and saves energy.
4. AEC Firms: Assess and Address
Using a building automation system is an efficient way to manage energy usage in buildings and identify problem areas. For example, 4tell™’s iPlan™ platform can show how a building operates and identify periods of peak demand. This helps track and control costs from a single source. AEC firms can get ahead of the curve when it comes to capturing and reporting on data for clients’ buildings.
For building repairs and capital investments, warmer seasons are a good time to perform those projects. During spring or summer, you won’t expose your buildings to extreme cold conditions that can damage equipment and systems.
These tips can help AEC firms prepare clients’ buildings for warm weather changes. Not only do properly maintained buildings have reduced operational costs and extended equipment life, this also helps improve their environmental footprint too.
