PROJECT SUMMARY Synergy is a project that incorporates dynamic design and innovative technologies, adapting to its surrounding environment to become a living, breathing machine. Synergy’s goal is to create a living environment that effectively benefits the city and its occupants by generating a better quality of life while achieving a net zero energy outcome.
RELEVANCE OF PROJECT TO THE GOALS OF THE COMPETITION Through the use of unconventional HVAC technologies which includes, the enVerid HLR ventilator, passive and daylighting strategies through site exploration, and the economic and eco-efficiency of modular construction, Synergy delivers net zero energy ready capabilities. The project also utilizes green roofs and solar strategies, and a roof solar array, to achieve net zero. Also introducing native flora to the site, alleviates the issues of hardscape while also naturally cutting down on air pollutants in the surrounding air, thus further benefiting the community and the occupants.
DESIGN STRATEGY AND KEY POINTS Daylighting Strategy Synergy’s approach to adapt to the varying environment lead to the introduction of the courtyard. This approach is vital to the schematic planning, natural daylighting strategies, and occupancy comfort of Synergy. Maximizing north natural daylighting is important for this climate, and the courtyard provides the units in the north sufficient natural light. This planning, through energy modeling analysis, resulted in at least 65%68% natural daylighting within living spaces. This percentage of daylighting is favorable for using less energy to light these spaces during the day.
Modular Strategy In conjunction with the modular construction of each unit, SIPS wall construction adds another layer of ingenuity and structural integrity. Through energy analysis, the structural insulation will be increased to an R-Value of around 45, for maximum thermal efficiency, as well as an air-tight envelope. In turn, this increase will cut down on energy consumption due to temperature controls within each unit. For insulation throughout the building the R-Values exceed the design goals of net zero ready such as: Walls R-45, Floors R-25, Accessible Flat Roof R-56. within the building.
Mechanical Strategy
Further development of the project resulted in the strategic planning of the mechanical cores sandwiched between a set of units. These cores were placed closest to the areas requiring plumbing and mechanical equipment. Thanks to modular construction, a stacking effect is achieved, thus minimizing the run of the plumbing and duct work throughout the units. Synergy’s harmonious relation between design and technology introduces the utilization of an HLR ventilation system, in conjunction with a conventional VRF Fan Coil system. This technology is already being used in large scale apartments and commercial buildings and has yielded favorable results in cutting down energy costs. This system also decreases the size of the required air handling units and duct work throughout the building. With this new technology implication, it eliminates the need for more conventional ventilation openings, allowing for a more thermally efficient envelope. In turn, this system allows for reduction on energy consumption and costs by 30-40%.

MEET THE CREW
TEAM INFORMATION Students will participate in the Race to Zero Student Design Competition as part of a two semester undergraduate design studio for academic credit. The design studios (Design 9 and 10) are part of Philadelphia University’s Bachelor of Architecture program and include both a design and research (thesis) component. Through a collaborative and multidisciplinary approach the studio will explore the challenges associated with this evolving typology including design, technological, and performance-based innovation, sustainable and best practices, cost effectiveness, energy efficiency (with and without renewable energy sources), and contextual responsiveness. Studio work will be separated into two phases to align with submission and technical requirements associated with the Race to Zero Student Design Competition and an informed integrated delivery platform. Phase 1 will focus on fundamental site and building design principals, an integrated design process, the principals associated with a Net Zero building enclosure and the essential elements of a Net Zero building. During this phase students will also complete the DOE Building Science Training Course (on line) and become familiar with REM/Rate and other energy modeling software. Phase 2 will focus on the technical design and documentation requirements of specific core construction practices, structural integration, and methods and materials of construction. Design and technical development and supporting documentation not covered during the fall term will become the framework of Design 10 which is offered in the spring.

PROJECT INTRODUCTION
PROJECT HIGHLIGHTS
ADAPTIBILITY Through further designing and planning, the units in Synergy have undergone major changes. The size of each unit has decreased in overall square footage by 60%. This is all possible by the utilization of multi-functionary factors, such as moveable walls, built-in wall storage, and hidden wall furniture. This strategic move also allows the units themselves to adapt to changes in daylighting, and occupancy functions.
MODULARITY. To decrease site degradation as well as building costs Synergy is based upon a prefabricated modular unit that will be sectioned off and brought to the site.

PROJECT INTRODUCTION
DAYLIGHTING Throughout the process of design development the team redesigned the building to make sure to maxmize on the daylighting that the site offers. With this reasoning the courtyard scheme was born. The team angled certain sides of the building to make sure that the units had at least 37+ lumen aspect ratio into the depth of the unit.
SYNERGY AS COMPARED TO A HUMAN BODY Through the development of Synergy we began to characterize the mechanical, eletrical, and other systems as well as the design of the building envelope to things comparable to the human body. Each part of the building begins to take on a human quality that allows for the building to become this living, breathing machine. Through understandings of vital organs such as the heart, lungs, eyes, kidneys, and skin we understand how to make a building become a successful living organism. These decisions will allow its inhabitants to be happy, healthy organisms as well.
INTEGRATION OF GREEN SPACE Throughout the whole project we wanted to make sure that green space had a key role in Synergy. We were able to utilize 20% of the site to green space for the community of the multi-family apartment building. Through these spaces we created a microclimate which begin to interact with our building systems to create better thermal comfort throughout the summer months and into the winter months.

PROJECT INTRODUCTION
SITE ANALYSIS BREWERYTOWN BACKGROUND In the 19th century Brewerytown was named for being home to many of Philadelphia’s breweries. The town underwent many changes throughout the years. Once all breweries, the town transitioned into a thriving residential community. Within the last decade Philadelphia has experienced a 42% growth in population specifically regarding young persons within the ages of 18-29. Within the last three years development in this area has increased to over 116%. Due to its location Brewerytown is an up and coming neighborhood of Philadelphia. Close proximity to the Fairmount Park and to Center City this town with a population of 39,040, is listed as one of Philadelphia’s most desired neighborhoods to live in. CHOOSING BREWERYTOWN FOR OUR SITE Based upon these findings of an ever growing, residential area, with over 7,000 family households already existing and a 42% growth in millennial population, we concluded that the site and new construction must be used for mixed-family residential apartment housing. Therefore allowing this area to become a completely diverse sector meeting the standard for Philadelphia region and Brewerytown, specifically.

PROJECT INTRODUCTION BREWER YTOWN GARDEN S
OUR SITE: CONTEXTUAL ANALYSIS The site resides in a heavily urban lot, in the neighborhood of Brewerytown, Philadelphia, PA. The lot is a ridged rectangular shape with a small overlap of 33 feet at the very north. This site rests in an urban landscape, thus possessing strong site potential and adaptability through surrounding context. This strong potential is also due to the surrounding edge conditions, which only the north side of the site is bordered by existing buildings, an existing Indigo Bike Sharing Station on Poplar Street, and a bust stop on 26th Street.

Our site located on the corner of Popular and Taney Street was listed as: CMX-2. Under the zoning code description for that category the site must be used as a mixed-use commercial and residential lot. The corner of Popular and Taney is densely populated with residences which directed our attention to the other corner of the lot. Under these constraints along with the analysis of the site we decided that a cafe was best suited on the corner of Poplar and 26th Street where it is accompanied with other commercial facilities. Due to the nature of being a corner site we are allowed to occupy 80% of the site and designate the other 20% to vegetation which Synergy meets. The maximum height for the lot is 38 feet with a minimum setback perimeter of 5 feet.

DESIGN GOALS Mechanical Efficiency
The mechanical cores are implemented to organize the network of piping and ducts of our building systems. Sandwiched in-between every unit is an architectural shaft that provides a more organized network of mechanical ducts and piping. This layout adds to a more efficient way to maintain these technologies. This also facilitates the reduction of ventilation openings and number of penetrations in the SIPS wall paneling system allowing for a more air tight envelope. Technology
Synergy is founded on the principle of creating a harmonious relation between design and energy efficient technologies. Through design strategies of modular units and the utilization of various technologies integrated in the project Synergy conveys our guiding principle in and out, adapting to the surrounding environment, occupants, and dynamic city. These technologies include the HLR ventilator acting as the lungs of the building, the water retention cisterns and pipes that consume water on site, and a solar active façade and roof-scape to absorb energy from the sun. Adaptability
The schematic layout for Synergy came from a more in-depth understanding of the site and the needs of the occupants. In order to adapt and maximize on southern winter daylighting, a courtyard scheme was investigated through energy modeling analysis. The units were also pushed back creating a staggered south façade. Pairing with the orientation of the building is the addition of more windows generating more daylighting into each unit. The data showed us that designing the apartments around a courtyard enhanced light quantity to the northern units. The new result is about 65% natural daylighting within the living spaces. The old unit layout was closed off and inhibited light throughout the space as well as being a static design that didn’t suit the occupants dynamic lifestyle. The modular units underwent a redesign that now allows for adaptable living. Walls and furniture can get tucked away to meet the growing and dynamic need of the user while also preserving open space. Suitable for any type of function working from home, dinner parties, or a cozy night at home. The walls slide into one another by use of a double track system that allows for the user to open up their space letting light filter through each section of their apartment. Now, these modular units become a dynamic but personalized home built for the ever-changing occupant.
Density
Synergy’s micro-modular units, allows for further site density, while still conforming to zoning restrictions. In relation to the new schematic planning of the building, this density does not negatively affect daylighting strategies and occupancy comfort. Site density is also favorable to meet market demand, and property value.

THE HEART
[COURTYARD]
The pump house. The role to provide the body with oxygen and nutrients while also carrying away waste. The role of the courtyard is to act as a natural way of bringing fresh air into the building and releasing stress on the HVAC system. We also want these cores to become the heart of socialization of the users.
THE LUNGS
[HVAC SYSTEMS]
The role of the lungs primarily is to bring air from the atomosphere and pass oxygen into the bloodstream; allowing the rest of the body to circulate the oxygen. The role of the HVAC system is to provide fresh outdoor air to dilute interior airborne contaminants, such as odors from occupants, volatile organic compounds (VOC’s) emitted from interior furnishings, chemicals used for cleaning, etc. In Synergy we use a VRF Fan Coil System with an HLR System.
THE SPINE
[MODULARITY, STRUCTURE]
The role of the spine serves as a pillar to support the body’s weight and to protect the spinal cord.The role of the our architectural spine acts as the literal building blocks to Synergy. Here, you are able to see how the modular units are used similar to how legos would be used. Stacked one atop the other which creates an organization for plumbing, electrical, and HVAC systems.
THE EYES
[WINDOWS]
The roles of the eyes are to convert light from the outside world into electrical nerve impulses. We are interpreting the windows to be the eyes of our architecture. The windows allow for the light to reach into the deepest areas of the units to reduce the use of artificial lighting
THE KIDNEYS [WATER COLLECTION] The kidneys maintain our body’s water balance by controlling the water concentration of blood plasma. Through our water collection system we are reusing grey water in order to maintain balance throughout our building.
THE SKIN
[BUILDING ENVELOPE]
The role of the skin is to protect, regulate and stimulate sensation. Its primary role is to act as a barrier. By integrating SIPs wall system we are creating a strong, energy efficient building envelope. The role of the skin is to protect, regulate, and stimulate sensation. Its primary role is to act as a barrier.

Prefabrication and modular construction are two of the larger strategic moves made in this project. Modular construction eliminates the need for large amounts of structure thus cutting costs on labor, site deterioration, and cost of construction. Separated in smalled units based upon bedroom size: two bedroom, one bedroom, and studio apartments. These modular units are constructed off site and trucked in. Each unit breaks off into even smaller compartmentalized sections. For dimensional and sectional reference see diagram [Figure 1.0] on the next page. Prefabrication
We are utilizing prefabrication techniques not only to cut construction costs which inevitably allows for rent to be cheaper, but also to ease the process of labor. We divided the building into sections that will fit into two different categories: build on-site and build off-site prefabricated. In order to do this we needed to divide the spaces of the corridor and units to one modular piece that would allow for construction assembly on-site to be cut by more than 50%. We also had to divide prefabrication technique into labor phases in order to generate a full-scale model. See [Figure 1.0].

Modularity
We chose modular construction due to its quality of construction, longevity, and strength. Building off-site fosters a structure that can withstand the rigors of transportation. This means wall, floor and roof assembly becomes an intregrated construction.

COURTYARD SYSTEMS
THE HEART
[COURTYARD]
The role of the courtyard is to act as a natural way of bringing fresh air into the building and releasing stress on the HVAC system. We also want these cores to become the heart of socialization of the users.
All rainwater collected on site will be re-used as grey water or for planting.
Figure 1.2
SOLAR PANELS Cutting down energy costs and protecting the environment are important, that is why Synergy utilizes solar energy to generate about 60% of its electricity from renewable solar energy.
STACKED PLUMBING In order to cut down on energy costs and consumption on the micro scale, the placement of plumbing fixtures was important in order to achieve a stacking effect thus limiting the run of hot water.
CENTRAL COURTYARD The central courtyard becomes not only a communcal element, but a multi-functional facet for natural daylighting, passive cooling, and passive ventilation.
GREEN WALLS The element of green space is important for natural cleansing of CO2 and other outdoor air pollutants, as well as functioning as a natural thermal barrier and dehumidifier.

SITE PLANTING STRATEGY
BREWER YTOWN GARDEN THESSITE. Design strategies for the site include reduction of hardscape by incorporating green spaces that focus on native based plants while also providing occupants and community members a pleasant environment. Located on our site is a regional bus stop. Instead of ignoring these features we want to highlight them by designating site specific areas providing pleasant seating for community members while they wait for their bus. Planting beds vary on the amount of light, shade, and durability. Shade meadow plantings are located in the shaded spots of the site, whereas, sunny plants are located on areas of the site that recieve a lot of sunlight. These plants thrive in the conditions they are put in. Salt-tolerant plantings are located in areas closest to the road. Known as Boulevard plants, they are found closest to sidewalks or roadways where they are subject to rough chemical hazards near road conditions. [Figure 1.3]

RAIN GARDEN Not only does this provide a micro-environment for birds and butterflies but is also a good way to allow for water to penetrate and filter pollutants. It also creates a quality of life for the residents and community members. There is also a mural opportunity for Philadelphia programs to participate in, such as Mural Arts Philadelphia. This brings philanthropic opportunities to the community.

LIGHTING& APPLIANCES
THE EYES
[WINDOWS]
We are interpreting the windows to be the eyes of our architecture. The windows allow for the light to reach into the deepest areas of the units to reduce the use of artificial lighting fixtures. Design Behind the Form
The new schematic layout for Synergy came from a more in-depth understanding of the site and the needs of the occupants. In order to adapt and maximize on southern winter daylighting, a courtyard scheme was investigated through energy modeling analysis. Pairing with the orientation of the building is the addition of more windows generating more daylighting into each unit. The data showed us that designing the apartments around a courtyard enhanced light quantity to the northern units. The new result is about 65% natural daylighting within the living spaces. [Figure 2.0] The old unit layout was closed off and inhibited light throughout the space, as well as being a static design that didnâ&#x20AC;&#x2122;t suit the occupants dynamic lifestyle. The modular units underwent a redesign that now allows for adaptable living. Walls and furniture can get tucked away to meet the growing and dynamic need of the user while also preserving open space. Suitable for any type of function working from home, dinner parties, or a cozy night at home. The walls slide into one another by use of a double track system that allows for the user to open up their space letting light filter through each section of their apartment. Now, these modular units become a dynamic but personalized home built for the ever-changing occupant.

UNIT DAYLIGHTING
DAYLIGHTING Due to the sites relationship to its solar condition we maximize on solar daylighting from the south. However, it was important to allow the units on the Northern side of the site to also achieve maximum daylighting. By incorporating a courtyard the units on the Northern side receive the same amount of daylight infiltration that the Southern units obtain with no obstructions. While our unit is designed to meet the users growing needs it also adapts to the changing of the daylight. We incorporated the use of frosted panel sliding doors that allow light to filter through without obstruction. Figure 2.0

CONSERVATION OF NATURAL RESOURCES Synergy we utilize ENERGY STAR-Rated products to ensure the best efficiency as well as cost effectiveness. An average household can spend up to $5,550 on energy bills annually. Our units contain appliances that cut traditional energy bills in half. By the utilization of ENERGY-STAR appliances, our units minimize the exploitation of natural resources by reducing the amount of natural gas, oil, coal, and water consumption. Designed for every unit is the introduction to motion censored faucets. This allows for the users to use what they need while also conserving as much water as possible.

COMMUNAL LAUNDRY ROOM
Instead of every unit having their own washer and dryer, we are implementing communal laundry rooms. By incorporating shared laundry we are effectively using ENERGY-STAR appliances that minimize chemical, water, and energy use. Our model by Kenmore requires less wash time and water consumption than a regular washing machine. This model is more efficient than a top-loading washing machine. Front-loading machines are generally more expensive, but produce better cleaning results, consume less water and are more gentle than top-loading washing machines.

SYNERGY
JEFFERSON UNIVERSITY RACE TO ZERO 2018
Sectioning the Modularity
We sectioned off the building so that the building as a whole can become a part of the prefabrication process, whilst others become a build-on-site construction. These design decisions allowed for 85% construction off-site and 15% on-site minimalizing the cost of labor. In figure 4.0, the grey is representative of the 15% built on site construction. This type of method allows for our building to be constructed in pieces. Some units are built off-site as a regular one unit construction. Others are paired with the corresponding Benefits of Modular Construction WASTE REDUCTION
Building in a factory reduces the amount of waste and therefore increases protection of building. THEFT REDUCTION
On-site theft is reduced because of off-site controlled building setting. FAST BUILD TIME
Since the project is split to on-site and off-site construction two jobs can occur simultaneously, allowing for 30-50% faster finish time.

Joint design should be highly considered for SIPs panels in order to avoid air penetration from the interior and exterior penetrations. If cold, damp, or humid air ends up reaching the interior or the outer sheathing layer it will cause damage and deterioration. Joint connections will be considered properly on site, which include seals within the thickness of the panel such as spray foam or gaskets. Having most of the building being modular allows for reduction of construction waste as well as save natural resources.

THE SKIN The role of the skin is to protect, regulate, and stimulate sensation. Its primary role is to act as a barrier. Structural Insulated Panels (SIPs)
By integrating SIPs wall system we are creating a strong, energy efficient building envelope. Due to the nature of how SIPs wall system is constructed, especially incorporating our prefabricated units, it cuts downs cost. Saving time, money and labor. By using SIPS wall system we are able to achieve our goals of a high-performance building enclosure. Compared to traditional construction SIPs construction provides a continuous vapor barrier while allowing a larger R-value. Normal SIPS construction includes two rigid board sheathing materials. The inner core sandwiched inbetween the ridgid board sheathing is expanded polystrene (EPS). EPS is pressure laminated together allowing for that continuous barrier and structural support. EPS is the least expensive of the foam fillers which is a completely recyclable material that is environmentally friendly. EPS foam insulation requires less energy than the traditional fiberglass insulation and also does not use any Chlorofluorocarbons (CFCs) in the process.

Longevity is inherent as long as there is proper lamination techniques applied in the manufacturing process. It is important to incorporate furring strips between the exterior face of the panel and the exterior cladding allowing the panels to dry out when water vapor enters the panel.

TENSILE FACADE Enhancing building thermal controls, tensile facade systems block solar heat and diffuse natural light. Reduction of lighting and cooling costs are highly benefical.
ECO-MESH This technology cleans the air while also cooling it whilst protecting the inhabitants by absorbing carbon oxide and heavy metals found in the air. Not only are their green benefits but aesthetically enhancing the area by incorporating more green.
METAL PANELS Versatile, durable, sustainable. Metal panels allow for quick installation and are not as heavy or carry the burden of cost that traditional masonry and concrete cladding have.
WOOD RAIN SCREEN Utilizing Climate-Shield Rain Screen Wood Siding System embraces the beauty of wood cladding but is strong and durable for an outlasting performance. Eliminates extra costs associated with labor and construction inadequacies.

Synergy’s envelope performance ultimately provides self-care to the building and keeps its inhabitants comfortable inside and outside. Synergy’s first approach to this is through its rainscreen, whichGutter provides an air gap between theGutter siding and theSIPs Gutter sheathing. The air gap benefits bothSIPs the exterior and Gutter SIPs interior spaces by managing moisture that accumulates GWB SIPs during cold weather and rain. This results GWB in a reduction of damage to materials because it allows the moisture8d Nails GWB Nails GWB to evaporate and dry quicker as well8das prevent waterBamboo 8d Nails Bamboo from penetrating the building’s envelope.

(IAQ) & VENTILATION
THE LUNGS The role of the lungs primarily is to bring air from the atmosphere and pass oxygen into the bloodstream; allowing the rest of the body to circulate the oxygen.
HVAC The role of the HVAC system is to provide fresh outdoor air to dilute interior airborne contaminants, such as odors from occupants, volatile organic compounds (VOCâ&#x20AC;&#x2122;s) emitted from interior furnishings, chemicals used for cleaning, etc. A properly designed system will provide a comfortable indoor environment year round when properly maintained. In Synergy we use a VRF Fan Coil System with an HLR System.
Utilizing a Balanced System VRF FAN COIL SYSTEM Synergy utilizes a balanced VRF fan coil system to distribute heating and cooling throughout the building. The zoning of the VRF system is strategically planned based off of temperature conditions and orientation of the building. The North and West sides of the building are grouped into one zone, which would predominately be heat dominated zones. The units facing the south side of the building are grouped under the cooling dominated zone. This allows for the system to balance itself, and distribute the consumption of energy. Using refrigerant, VRF systems move heat between an outdoor unit (typically an air source or ground source heat pump) and one of many indoor units used to heat or cool an individual zone in a building. VRF systems have the ability to modulate the amount of refrigerant sent to each zone independently and in tune with diverse and changing space conditioning loads, thereby increasing energy savings. VRFs use a R-410a refrigerant, which is more energy dense than water or air. This means that a smaller volume of vapor or liquid refrigerant is required to move the same amount of heat. This can result in pumping motor savings and a more efficient transfer of heat to/from zones HEAT RECOVERY UNIT (Branch Controller) A heat recovery unit (HRU) allows for the simultaneous heating and cooling of several individual zones that are co-located on the same main refrigerant loop. For example, an HRU might extract heat from the refrigerant returning from a cooled zone to heat refrigerant leaving for a different zone that is currently in heating mode. By reusing the heat that can be extracted locally, HRUs can reduce the size of the overall heating and cooling loads that must be satisfied by the outdoor unit. The potential energy savings of utilizing this type of HVAC system, ranges from 10-30%. 42

In conjunction with the ERV, the HLR system is attached to the Ventilator on the roof of the building. The enVerid HVAC Load Reduction (HLR) module is an intelligent scrubber that removes all indoor air contaminants, including carbon dioxide (CO2), aldehydes and volatile organic compounds (VOCs).
When adjoined to the ERV system, the HLR module can result in a reduction greater than 60% in peak heating or cooling loads. Cleaning the indoor air instead of constantly replacing it with outside air, dramatically reduces the energy used by HVAC systems (in this case the VRF fan coil system) to heat or cool the outside air being brought into the building. In addition to removing indoor air contaminants, HLR technology also reduces the outside air pollution entering the building. This is a major benefit in metropolitan areas or near highways, airports, and highly trafficked areas. This is applicable in the heavily urban neighborhood of Brewerytown. With people spending 90% of their time indoors, indoor air quality has an enormous impact on health. Multiple studies showing that better indoor air quality can increase cognitive performance, health and productivity. The HLR 1000E-R module has the capacity air flow of 800 CFM. This inflow air take allows for the reduction in the sizing of the ERV module due to the lessening need for outside air intake. Based off of the infiltration calculations of the gross square footage of the appropriate HVAC zones and utilizing the HLR system, this allows for an ERV system with a Typical Airflow Range of about 1000 CFM to be utilized. Thus, with the use of a smaller ventilator system, the sizing of the ducts has decreased to about 5 inches being distributed into the units. In turn, this reduction in duct sizing now allows for more floor to ceiling height increase and flexibility.

As “Cores” became an important concept for Synergy’s design strategies, the mechanical core functions as the lungs of this living breathing machine. Providing individual vertical spaces sandwiched between each unit allows for efficient space for the units to “breath”. Located in these cores are utilities, such as an HLR system, a VRF system, an ERV system, a branch controller as well as plumbing. These systems work together and run vertically down into the mechanical channel and into each unit to create a comfortable space for its inhabitants.

The system captures drain water from showers, tubs, and washing machines and directs it to a holding tank where it is filtered and pumped back into flush toilets. This reduces the amount of potable water and relieves strain on water treatment plants. Philadelphia’s annual rainfall is 41.45 inches, which is not drastically high, but by incorporating rainwater collection into our greywater system we can capture the water and utilize it for other purposes.

Tankless Water Heaters Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed. They don’t produce the stand-by energy losses associated with storage water heaters, which can save the project money. Based off of the estimating worksheet for peak water demand within the different unit types, each studio and one bedroom would need a water heater model with a first hour rating of 30 to 34 gallons. Each two bedroom unit would need a water heater model with a first hour rating of 54 to 58 gallons. For homes that use 41 gallons or less of hot water daily, demand water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters. They can be 8%–14% more energy efficient for homes that use a lot of hot water around 86 gallons per day. You can achieve even greater energy savings of 27%–50% if you install a demand water heater at each hot water outlet. ENERGY STAR® estimates that a typical family can save $100 or more per year with an ENERGY STAR qualified tankless water heater. Water Heater Model: Stiebel Eltron Tempra 24 Plus. The flow rate of the Tempra 24 Plus, ranges from 0.58 GPM – 5 GPM. This range will depend on the temperature rise required. For the most part, getting close to 5 GPM will provide enough flow for 2 bathrooms and other common utilities of a medium sized home.
Demand - Hot Water Systems Demand hot water recirculating systems can save water and energy in some situations. Potential benefits of installing a demand recirculating system during your next new construction or home retrofitting project, include: Demand recirculating pumps have the potential to solve the problem of a long wait for hot water at a distant fixture, while simultaneously saving energy, water and money. You no longer need to send cold water down the drain while waiting for warm water. Instead, recirculating pumps rapidly pull hot water from a water heater, while simultaneously sending cool water from the hot water lines back to the water heater to be reheated and reused. Demand systems can be controlled by the push of a button, a timer, or motion sensor. [Pump Being Used: UP15-10SU7P TLC, Comfort Hot Water Recirculation Pump, 3/4” NPT, 115 V]

Another advantage to this strategic approach, is the shortening of hot water supply time to each water fixture. By cutting down the amount of pipe run and creating a hot-water plumbing loop system water continually moves in an efficient cycle.

JEFFERSON UNIVERSITY RACE TO ZERO 2018
PROJECT SUMMARIZED
INNOVATIVE STRATEGIES From the beginning of the project’s life, research and in-depth insight of innovative technologies was taken into consideration. Exploring the use of HVAC technologies that are not commonly used at this scale, proved to be beneficial to the building’s overall energy performance. While technology was a big part of this complex system, the design of the building was just as important, if not more. Synergy’s approach to adapt to the varying environment lead to the introduction of the courtyard. This courtyard, became the “heart” of the design. It allows for the low southern winter sun to reach to units in the back of the building, while also helping achieve passive cooling during the summer months. As the design and the technology merged, this idea of the building being a living, breathing, machine was born. Further development of adding new technological systems, and energy conserving methods, lead to a more complex network of energy systems. Systems such as the water cisterns on site, drink the water coming from the runoff of the building, and store for use in grey water and landscaping. Viewing the building as a complex organism, gives new meaning to the architecture, and allows for a better understanding of how the building is energy efficient and adaptable to its surroundings. Like the cells in the human body, the micro-units can adapt to both its occupants and the infiltration of daylighting. This adaptability is due to the introduction of collapsible furniture systems tucked away within the walls, and movable panel walls. These features within the units also affects the overall “health” of the structure. This planning, through energy modeling analysis, resulted in at least 65%-68% natural daylighting within living spaces, in turn cutting down on energy consumption in the overall building. The strategic planning of the mechanical channels sandwiched between a set of stacked units, is a way of organizing the MEP and plumbing distribution. Instead of the conventional way of scattered mechanical equipment in mechanical rooms and long runs of plumbing to reach the water heaters, the mechanical channels give organization and balance to the system. Synergy’s careful consideration for the complex technological systems, married with the design of the overall building, has proven to reach net zero energy capabilities.
