Matthew Wiechart, PE, CxA, LEED AP, CEM Principal/Senior Automated Engineer, TLC Engineering for Architectonics Inc., Orlando, Fla.

CSE: What abnormal systems or appearance are owners requesting to accomplish their accessories added efficient-for example, thermal action accumulator or accumulated calefaction and ability (CHP)?

Holbert: One of our university audience in a Southern accompaniment chip chilled-water thermal accumulator via an acceding with an action account aggregation (ESCO). The ESCO installs and operates the thermal accumulator system, acumen revenues through optimizing time-of-use electricity rates, acclimate conditions, and a demand-response acceding with the bounded utility. This university additionally is amalgam solar PV on its campuses. An absorbing approaching abstraction could be leveraging the thermal accumulator tanks as a array to abundance balance PV generation.

Wiechart: Cogeneration and trigeneration are connected altercation items. Compassionate abject loading of an assimilation chiller, administration of all-embracing accustomed gas, and opportunities for hydronic reheat can accomplish these systems attractive. Chilled-water accumulator additionally is acclimated to accommodate for back-up and aiguille energy-load shaving.

Sylvain: We accept apparent assorted approaches as of late. Some audience accept focused on carbon and low-energy/renewable systems, while others accept focused on action costs and resiliency. To acknowledge to the latter, we accept been asked to appraise and apparatus CHP in a cardinal of locations. CHP provides an adorable action amount and appeal accumulation while alms a campus added airy ability adequacy and acceptance for added uptime in the accident of an connected filigree outage.

CSE: What types of acceptable appearance or apropos ability you appointment on such accessories that you wouldn’t on added projects?

Sylvain: This varies depending on the client’s approach, but absolute and abstinent action acceptance basis (EUI) and aiguille action draw is a constant affair we accept been seeing. Owners in general, and universities specifically, assume to be added anxious with how abundant action they will absolutely be application than they are with how abundant abstract accumulation a predesign archetypal shows adjoin a abstract baseline.

Holbert: It seems added projects are advancing developer-led and financed projects for action ability and renewable energy. These types of projects can be a win for owners if analytical aspects of the agreements are appropriately aligned. The ESCO acceding risks for HVAC systems assume to be almost acclaimed aback they accept been about for a while. Leasing buyer amplitude for renewable action bearing is new. Some aspects to accede are the acceding of the acceding and about-face to the owner, optimizing the admeasurement and area of the arrangement to accretion the best value, and compassionate the amount of the amplitude that is actuality angry over to the developer. For example, developers generally adopt to abode PV in accessible fields to abate cost; however, the buyer needs to accede the amount of that acreage for the future. PV systems can tie up acreage throughout a advantageous action that can ability 50 years.

Wiechart: The composure of the architectonics automation arrangement and the assay of the arrangement is provided on university and academy jobs area added action types do not accept that akin of sophistication.

CSE: What types of renewable or another action systems accept you afresh defined to accommodate ability for academy or university projects? This may accommodate photovoltaics, wind turbines, etc. Describe the challenges and solutions.

Sylvain: In accession to the gas-fired CHP mentioned earlier, we afresh accept had a cardinal of university audience apparatus all-embracing PV renewable action systems, both at a campus scale, at William Patterson University, Wayne, N.J., and on a architectonics scale, for a architectonics in following of net aught action at Millersville University, Pa.

Wiechart: Abundant of our assignment is in Florida, area the prevailing apprehension can about-face from day to day-if there is a prevailing wind. Therefore, wind turbines are not able uses of basic due to poor return. PV panels are the preference, and as technology increases in ability and costs are minimized, these systems will become alike added prevalent.

Holbert: We accept apparent the best action with solar PV systems. Primarily because prices accept fallen, they accommodate a actual arresting sustainability commitment, and they are an adorable advance for specialized developers. Some universities access into offsite power-purchase agreements for wind energy. These can accommodate a ample carbon account for the university that is beneath complex, fast to procure, and generally beneath cher than campus action ability efforts and onsite renewable action systems.

CSE: What are some of the challenges or issues aback designing for baptize use in such facilities?

Wiechart: Ample campuses accept issues with their baptize acceptance and capacities. The accomplishing of application reclaimed or greywater helps them with those accommodation issues. Proper administration and basal sterilization charge occur, but these issues are adequately accessible to mitigate. The use of biscuit toilets and sinks in lieu of white helps abate the staining that sometimes occurs with these systems.

Holbert: Baptize has consistently taken a aback bench to energy. This is generally due to cost; for some facilities, baptize is alike free. We do not ahead this actuality the case in the future, as baptize availability is abbreviating in abounding geographies. One of the issues that arises is that baptize and action burning generally can compete; dehydration of baptize generally is acclimated to accomplish HVAC accessories added efficient. In added cases, they can assignment together. Baptize from dehumidification is apple-pie and can be alternate to water-consuming systems. Baptize accumulator seems to be a alive factor-it is expensive, large, and abundant to store. It additionally needs to be bankrupt for use in the facility. This is added big-ticket to do onsite than at a accessible water-treatment plant. New technologies that are efficient, accept a baby footprint, and can be acclimated in absolute time (without ample accumulator needs) accept the abeyant to accomplish a big appulse on this topic.

Sylvain: The baptize challenges we accept focused on afresh are energy-related or focused on reclaim for automated systems. The action focus has been in the anatomy of calm hot-water generation, application renewable (solar), abbreviating boilers, and accumulated architectonics heating/domestic plants. The reclaim focus has been on building-collected or a sitewide accumulating of stormwater, which can be advised and acclimated as cooling belfry composition baptize for a commune plant.

CSE: How has the appeal for action accretion technology afflicted the architectonics for these kinds of projects?

Sczomak: I would say that the appeal for action ability has afflicted the architectonics for college/university projects, which in about-face has apprenticed the appeal for action recovery. Added use of action accretion from bankrupt air is actuality apprenticed by action codes, which in contempo years accept abundantly added the requirements. At the architectonics and campus bulb level, on assertive college/university projects we accept been implementing calefaction accretion in the anatomy of calefaction pump chillers to actual calmly abode the times aback both heating and cooling are appropriate in a building. Unlike a archetypal water-source calefaction pump system, in which abstracted calefaction pumps accomplish accompanying to abode accompanying heating and cooling requirements in a building, a distinct calefaction pump alarming draws calefaction from the building’s chilled-water arrangement and transfers it to the heating hot-water system, which is a abundant added able way of acclamation accompanying heating and cooling needs aback endless are balanced.

Wiechart: Action accretion has added badly as action codes accept become added stringent. The use of enthalpy auto from accretion has become a accepted architectonics practice. Educating owners apropos the aliment of this accessories is the key to abiding success and connected action conservation.

Locke: The action accretion articles accept acquired rapidly and are authoritative an appulse on action use. The educational accessories crave ample quantities of blast that charge be exhausted. Through the use of these devices, the blast air can be preheated or precooled to accommodate accustomed entering-air altitude while abbreviation the heating and cooling bulb accessories sizes.

Sylvain: This has had the better appulse on absolute barrio that are retrofitting/upgrading automated systems. Specifically, it is generally a claiming to calmly and finer fit action accretion systems and accumulation and acknowledgment administration into the constraints inherent in an absolute building. We accept had to get artistic with how and area we balance energy, what average is used, and how we accent the exhaust/relief airstreams to balance from.

Holbert: Action accretion is accepted convenance in abounding altitude zones-and appropriate by codes and standards in assertive altitude zones. For airside action recovery, this pushes the architectonics against committed outdoor-air systems. These systems additionally save a lot of reheat action for the project. For projects with aerial air-change requirements (thus aerial reheat loads) like labs and bloom affliction projects, we see waterside action accretion as an able advantage to save energy.

CSE: High-performance architectonics strategies accept been apparent to accept an appulse on the achievement of the architectonics and its occupants. What value-add items are you abacus to these kinds of accessories to accomplish the barrio accomplish at a academy and added able level?

Horkey: High-performance strategies are usually a aggregate of amount reduction, action efficiency, and amount matching. We accept a committed aggregation of achievement analysts who are affianced in the architectonics action to quantify the appulse of architectonics appearance on advancing achievement and accretion insights into the acknowledgment on advance and lifecycle amount of anniversary measure, with the aim of accouterment predicted achievement abstracts for actionable intelligence. They assay assorted strategies’ impacts on the all-embracing architectonics including:

Holbert: It seems the accomplished 10 years accept focused on HVAC arrangement technologies as primary drivers to accredit low action use. Added recently, we are accretion focus on acquiescent strategies aboriginal and again addition these with alive HVAC systems. New assay approaches accept enabled thermal and aurora freedom studies to abundantly acquaint the architecture. These approaches aboriginal optimize how able-bodied the architectonics performs application its own acclimatization and accumulation after the use of HVAC and lighting. This after-effects in a abundant advance in the thermal and beheld abundance of the addressee from the beginning. HVAC and lighting systems are again leveraged to supplement and actualize a awful adorable calm environment. With HVAC systems, we still focus on befitting them simple by centralizing aliment to specific architectonics areas or systems. This allows specialized buyer agents or a distinct aliment arrangement to handle the added circuitous apparatus of the architectonics while acceptance ambiguous aliment to abide accustomed and simple for centralized aliment staff. A few examples accommodate capricious refrigerant breeze (VRF) systems, awful able VAV, or centralized water-to-water calefaction pumps with broadcast terminal units and a committed outdoor-air system.

Sylvain: The account can be broad, but one of the aboriginal things that comes to apperception is architectonics abstracts for the occupants, accurately thermal-comfort, air-quality, and energy-usage advice presented in a way that makes them see the affection of the amplitude they abide and shows the action appulse of the decisions they make.

Wiechart: Absorptive air-filtration accessories that abbreviate airy amoebic compounds (VOCs) and carbon dioxide acquiesce the architectonics to be appropriately “cleaned” while aspersing ventilation. These designs accommodate abundance and are energy-efficient, which are goals of high-performance buildings. High-performing barrio additionally use controls to automatically set aback systems, which accommodate temperature, lighting, and alike ability to save action while not affecting archetypal animal behaviors.
