As part of any construction planning and execution process, businesses are always looking for proactive ways to safeguard their investment, create efficiencies, and effectively deliver to client requirements. One powerful tool in this industry is the HVAC dilapidation report, a comprehensive document that assesses the current condition of HVAC systems within a property before any adjacent construction or development work commences. We've put together more information on how to use HVAC dilapidation reports in your next project.

𝗛𝘆𝗱𝗿𝗼𝗻𝗶𝗰 𝗕𝗮𝗹𝗮𝗻𝗰𝗶𝗻𝗴: 𝘁𝗵𝗲 𝗦𝘁𝗮𝗻𝗱𝗮𝗿𝗱𝘀 & 𝗗𝗿𝗶𝘃𝗶𝗻𝗴 𝗙𝗼𝗿𝗰𝗲 𝗕𝗲𝗵𝗶𝗻𝗱 𝘁𝗵𝗲 𝗡𝗲𝘄 𝗥𝗲𝗾𝘂𝗶𝗿𝗲𝗺𝗲𝗻𝘁𝘀 Hydronic Balancing plays a critical roll in the performance of any hydronic heating and cooling system. For that reason alone, ASHRAE has made hydronic balancing a non-negotiable stop on the road to compliance with ASHRAE 90.1-2010 (or 2013), starting with this requirement: 1.    𝗣𝘂𝗺𝗽 𝗛𝗲𝗮𝗱: Pump differential pressure (head) for the purpose of sizing pumps shall be determined in accordance with generally accepted engineering standards and handbooks acceptable to the adopting authority. The pressure drop through each device and pipe segment in the critical circuit at design conditions shall be calculated. Furthermore, systems must be balanced: 2.    𝗛𝘆𝗱𝗿𝗼𝗻𝗶𝗰 𝗦𝘆𝘀𝘁𝗲𝗺 𝗕𝗮𝗹𝗮𝗻𝗰𝗶𝗻𝗴: Hydronic systems shall be proportionately balanced in a manner to first minimize throttling losses; then the pump impeller shall be trimmed or pump speed shall be adjusted to meet design flow conditions. And finally, there is this: 3.    𝗚𝗲𝗻𝗲𝗿𝗮𝗹: Construction documents shall require that all HVAC systems be balanced in accordance with generally accepted engineering standards. Construction documents shall require that a written balance report be provided to the building owner or the designated representative of the building owner for HVAC systems serving zones with a total conditions area exceeding 5000 ft2. All of these standards are interrelated. Accurately calculating pressure drops ensures that pumps are not oversized. Oversized pumps can lead to inefficient pump operation over the life of the system. Flow balancing (during and after commissioning) is how we make sure that we only put as much energy into the system as we are take out. Flow balancing is also how we begin to benchmark the performance of our buildings, a practice that ASHRAE aspires to make commonplace. It is all part of a long-term plan to drive more and more buildings to net zero energy performance.

To those who are interested in going deeply into one of the most important topics in HVAC design and construction work. HVAC systems commonly used 2-way control valves with commissioning sets, but challenges arose due to pressure fluctuations, causing control valve authority to drop below 50% during part-load conditions. Many studies found that this set was often inefficient in part-load situations, leading to either excess flow rates through the control valve or, conversely, a risk of valve starvation. The inefficiency in part-load conditions was attributed to the pressure-dependent nature of the 2-way control valve and commissioning set. Without delving into detailed explanations, these studies revealed that the system struggled to maintain optimal performance under varying loads. Specifically, during part-load scenarios, the flow rates through the control valve tended to deviate from the desired levels, creating operational challenges. To address this, some opted for Differential Pressure Control Valves (DPCVs) to make the system partially or fully pressure-independent.  As shown in the figure below CIBSE recommended limiting DPCV settings to 150% of the differential pressure across the index terminal unit sub-circuit at design flow rate with a maximum of 12 terminal units per sub-circuit. (A 50% increase in differential pressure with the DPCV set at 150% results in a 22% higher flow rate which could be acceptable). While effective, installing DPCVs in each terminal circuit will convert it to be fully pressure-independent but also very expensive. As a solution, Pressure Independent Control Valves (PICVs) emerged. PICVs offer a more cost-effective and efficient way to maintain stable performance under varying conditions, making them a preferred choice in modern HVAC design which gives a valve authority almost 1 in all part load cases and if it works at the minimum pressure required for its functionality.
