NATHAN JOHNSON “WE TRY TO BE HONEST. IF WE WANT TO DECORATE A CHURCH, WE LET THE STRUCTURE DO IT INSTEAD OF APPLYING ORNAMENTS.” NATHAN JOHNSON

BIOGRAPHY Nathan Johnson was born in 1925 in Herington, Kansas. When he was in eighth grade, his teacher asked what he wanted to be when he grew up. Johnson said he wanted to be an artist. And she said, “Nathan, artists aren’t appreciated until after they’re dead, why don’t you become an architect instead?” Which is why he became an architect.1
Herington, Kansas was a small town of 3500 citizens, described by Johnson as only having 35-40 black residents. Nathan Johnson was inspired and mentored by a white grade school teacher named Roxy Frost who has connected him with others who have started to help later on in his life. Since Johnson had an early talent for drawing, his grade school teacher steered him away from his original consideration of being an artist and encouraged him to pursue an interest in architecture because she explained to him, “you’ll live your whole life and never be respected,” indicating to the life of an artist where he would not be recognized while he is still alive. Johnson took that advice and went on to study. Prior to his education, Johnson also served in the US Navy.3 Later, Johnson moved to Detroit in 1950 to further pursue his career as an architect. He took a position with White and Griffin. Knowing that White was the first black architect registered in Michigan. Eventually, Johnson moved on to work with Harold H. Fisher and Victor Gruen & Associates who are notable for designing and building the Eastland and Northland malls.3 8
Johnson humorously reminisced that church commissions were the only jobs that he could be a part of at one point in his career. Johnson found his niche architectural expression in the modernist style, eventually being tapped by the Detroit Board of Education to become the first appointed African American architect for the board. This entry into designing and building schools led to more work.2 Nathan Johnson & Associates, Inc. was specifically an African American owned architecture firm, which was owned by Nathan Johnson. This firm was located at 2512 West Grand Boulevard, which is on the corner of West Grand Boulevard and Wabash Street. The building itself and its neighboring structure were purchased by the owner, Nathan Johnson, in 1960, and subsequently conjoined and remodeled as one office for his architecture firm which was established in 1956.1
to correctional facilities and the city’s People Mover stations. Nathan Johnson is a prolific designer in Detroit’s built environment.2 Nathan Johnson & Associates was rewarded with a Gold Medal in the year of 2018. It is the highest honor that AIA Detroit can give to individuals. It is conferred by the AIA Detroit Board of Directors in recognition of most distinguished service to the theory and practice of architecture to AIA Detroit.3 By the end of Johnson’s career, he was licensed to practice architecture in 13 states: Alabama, California, District of Columbia, Florida, Georgia, Illinois, Kansas, Kentucky, Michigan, New York, North Carolina, Ohio, and Texas.1
Johnson established a firm in I956, which lasted to about the 1990’s, an unrestrained time in the civil rights movement. The practice began in the basement of his home on Lawrence Street with only two employees. In 1960, the firm moved to 2512 West Grand Boulevard, Detroit, where it grew and eventually employed about 40 architects, designers, planners, and technicians.1 The work of this firm is seen in almost every district of Detroit. Their work ranges from private and multifamily residences, to schools, churches and restaurants,

HISTORIC DISTRICT GUIDELINES Owning a home in a Historic District has many advantages. The homes in the neighborhood always have a specific standard they need to be kept at, therefore the houses tend to be well maintained, thus increasing the housing market in return. However, if you wanted to change something about the exterior of your house there are certain guidelines you will need to follow. Keep in mind each house and Historic District has its own set of guidelines, for more information you can visit your cities official website about the guidelines and restrictions. Changing the facade our any outdoor features when within a historical district can be very limiting, each change will need to approved by the Historic District Commission and once approved you will need to apply for a building permit.

RESIDENTIAL WORKS AN IN-DEPTH LOOK AT NATHAN JOHNSON’S HOUSING PROJECTS As a predominant architect in the Detroit area, Nathan Johnson has many projects. However, there are only a handful of residential works. Three notable works include the Hong Residence, Broadstreet Residence and 4098 Fullerton. Out of these three, 4098 Fullerton has been the most neglected and in need of major preservation efforts to restore the home back to a functional state. The importance and value of this home is the reason why it merits to be preserved – to honor Nathan Johnson’s legacy.

EXISTING CONDITIONS RUSSELL WOODS IN THE MODERN DAY
As the largest historic district in Detroit, Russell Woods offers a lot of potential for new opportunities to respond to its ecological context. The City of Detroit had worked in conjunction with Lorcan Oâ&#x20AC;&#x2122;Herlihy Architects to develop a neighborhood plan for Russell Woods and Nardin Park. The greatest identified issue are the vacant buildings. Revitalization plans include removing blight and activating vacant lots with programming, creating gateways into the historic neighborhoods, and infusing parks, commercial buildings and crosswalks with art.

Reducing carbon emissions of a building is often associated to the operational carbon consumption, but the embodied carbon of a project also plays a large role. By restoring a home, it can extend the lifespan of the building and also help avoid the embodied carbon needed to replace an old building with a new one1.

UNDER CONSTRUCTION REVIVING THE FORMER GLORY OF FULLERTON These series of images show the state of 4098 Fullerton Ave., after many years of no occupancy. Many of the features that are unique to this home are intact, but the structural integrity of the home itself has been compromised. With new effort to revive this home to its former glory, re-stabilization of the structure and roof have been undertaken to begin the process of restoring this Nathan Johnson home.

CURRENT CLIMATE ANALYZING LOCAL WEATHER AND ITS EFFECT ON 4098 FULLERTON The environment influences all aspects of designing a building. Local weather, soil, and natural sun paths affect all project types; from small local gardens to new housing construction to larger buildings in downtown Detroit. It is important to understand these elements and how they impact a building, to design an efficient and sustainable home.

FUTURE CLIMATE ANALYZING AND DESIGNING FOR CLIMATE CHANGE IN THE COMING DECADES The climate of today will not be the climate of tomorrow. This section takes a deeper look into the future climate of the mid-west and focusing on the impact that climate change will have on the City of Detroit and the ways that we can be proactive about our choices (to lessen the effect that it will have on us). Historically and in more recent times, Detroit has become an example of storm-water surge flooding, which has caused over 20 million dollars in damages. It also causes sewer systems to overflow into the cityâ&#x20AC;&#x2122;s potable drinking water, leaving residents without fresh water for days.

LOOKING TO THE FUTURE ANALYZING THE CLIMATE DATA FOR 2041-2070 Analyzing the climate date for the years of 2041-2070 we can take a closer look at the way that climate change will influence our region and the way we handle design. The mid-west as a whole is going to experience a slight increase in precipitation each year in the form of rain and snow. This correlates with the data showing that we will have less consecutive dry days and more rainy days , seen in the graphs on the left. Looking to the graphs on this page, it shows the increase in temperature during both the day and night. Due to global warming the cycle of warm days and cool nights will shift to have both warmer days and the nights will also get warmer. While Northern Michigan and Canada will see a drastic change in temperature at about a 5° increase. Our location in Southeast Michigan will also see an increase but not as drastic as those living in the north part of the state.
57
FLOODING AND STORM-WATER MANAGEMENT ANALYZING THE CLIMATE DATA FOR 2041-20701 According to the Federal Emergency Management Agency (FEMA), the site of the project is not in an area of present flooding hazard. However, this may not represent event of a storm surge over-flowing the sewer system. The property currently pays a drainage charge of about $18 a month. Other properties around our site pay up to $40 a month in drainage fees totally to over $450 a year of added fees on the water bill. Through the simple practice of rerouting the downspout on the house can reduce this cost by almost half such as rain-water harvesting, downspout re-routing, bio-retention, and installing permeable pavement, the drainage charge can be avoided all together. Through a small investment in permeable paving or brick drive and walk ways can not only lower the amount of surface but also add credit that can be taken away from the new total amount of impervious surface.
25%
of residential parcels do not allow water to absorb into the ground.

of the drainage charge can be reduced through simple practices.

PASSIVE STRATEGIES HOW TO MAKE AND KEEP AN ENERGY EFFICIENT HOME Passive strategies use no energy and capitalize on natural resources like the sun and wind. These strategies like cooling a house through natural ventilation in the summer, heating a house by using energy gained from the sun (solar gain) in the winter, and changing every day behavior year-round can help reduce your energy bills and are good for the environment.
61
EFFICIENT BUILDING SHAPES COMPACT
Best in heating-dominated climates like Northern Michigan. Low surface area controls minimizes the chance for heat loss.1 Southeast Michiganâ&#x20AC;&#x2122;s ideal shape is between compact and compact with wings as Climate Change takes place.
COMPACT WITH WINGS
Best in slightly warmer climates that require both heating and cooling like Kentucky or Tennessee. The shape can keep in heat, but also allows for natural ventilation needed in warmer months.1
COURTYARD
Best in cooling-dominated climates, like Southern California. Courtyards are used to allow for air circulation inside and around the building.1
THIN WINGS
Best in extreme cooling-dominated climates, like deserts. Thin wings allow for constant air circulation to cool the building and its occupants.1 62
THERMAL MASSES2 Thermal masses are made of masonry materials that heat up from direct sunlight to release heat over the night into the space These can be made of stone, rock, concrete, brick, etc. They must have thickness to be able to adequately trap the heat, but can be in the form of wall or floors.
63
PASSIVE STRATEGIES BUILT STRATEGIES
BEHAVIORAL STRATEGIES
Use trombe walls (south facing masses made of brick, stone, concrete, etc.) to trap heat during the day and release at night.2
Night flush in the summer by opening windows at night to ventilate out hot air and close windows in the morning to trap in cool air.3
Locate garages on the north side of the house to shield from strong winter winds.3
Keep doors and windows shut when using air conditioning or heating.3
Use jump ducts above doors to maximize air movement throughout the entire house.3
Hang clothes up instead of using dryers for clothes. Take advantage of breezes for ventilation by opening windows to circulate air through a house in warmer months.3 Limit water use by taking quicker showers, turning off the faucet when brushing teeth and washing face, and reusing bath towels. Save up to 10% each year in heating and cooling by raising the temperature 7째-10째F for 8 hours a day in the summer or lowering it 7째-10째F for 8 hours in the winter.5
64
EASY FIX STRATEGIES Switch incandescent bulbs to LED bulbs. LEDs use up to 90% less energy and can last 25 years longer. The upfront cost may be higher, but it will save about $80 in electricity cost over the lifetime of the bulb.4 Use ENERGY STAR® certified light fixtures to save up to $14 per fixture.4 Angle downspouts onto the lawn or into rain collection barrels. This water is considered “graywater” and can be used in gardens and on lawns or can be connected to systems in the house to replace or supplement water needed for showers, faucets, and/or laundry.6

INSULATION RESIDENTIAL INSULATION AND ITS IMPORTANCE A greater energy efficiency and understanding for the importance of sustainability is driving better building energy codes, meaning better and tighter insulated buildings. However, most American homes were built prior to standard building codes which means many Americans can significantly benefit from adding insulation to have a more energy efficient home. From small changes to larger renovations, you can take steps to better insulate your home.
69
WHATâ&#x20AC;&#x2122;S THE DIFFERENCE? Spray foam and rigid foam are the two most popular types of insulation for residential homes. Here are the differences between the two: SPRAY FOAM RIGID FOAM Insulation + Air sealing Excellent (foam Excellent (foam expands to fill expands to fill gaps and cracks) gaps and cracks)

WHY INSULATE? IS YOUR HOME POORLY INSULATED? Below are some signs of poorly insulated homes. If you checked off one or more boxes, your house is likely under insulated.1 hot and stuffy in the summer; very cold in the winter cold floors high energy bills upper floor is 5-10 degrees hotter than main floor in the summer; and colder than the main floor in the winter different temperatures in different rooms drafty rooms outdoor noise is audible indoors: lawn mowers, traffic, animals require usage of portable heaters, extra blankets visible floor joists in the attic
71
TYPES OF INSULATION + PROJECTS WHAT DOES THIS ALL MEAN? Benefits of a well insulated home include better comfort, saving money, and helping the environment by lowering the levels of carbon dioxide. It can also increase your homeâ&#x20AC;&#x2122;s value.

AIR TIGHTNESS UNDERSTANDING THE BUILDING ENVELOPE Airtight construction, or airtightness, quite simply means that there are no unintended gaps in the building envelope that allow air to leak in or out of the building. This means there are no cold droughts coming in through the building envelope. It also means there are no unintended gaps that allow air from inside the building to leak into the materials of the building envelope. Unintended gaps can be a result of poor design and detailing that doesnâ&#x20AC;&#x2122;t allow junctions to be constructed well and fully sealed. It can also be the result of poor quality work on site or mistakes during the construction.

WHY BUILD AIRTIGHT? The restriction of air movement by the air barriers system is one of the most important functions of the building enclosure and, in some cases, the interior partitions. air is a transport mechanism for water, vapor, heat energy, and airborne contaminants. as a result, uncontrolled air leakage can lead to moisture issues from condensation and bulk water ingress, excessive heat loss that leads to discomfort and energy waste, as well as poor indoor air quality that affects occupant health and comfort.2
Air barriers stop air leakage through individual holes.
77
WHY?
EXPLAIN
AIRTIGHT CONSTRUCTION IS REQUIRED TO PROTECT THE BUILDING ENVELOPE.
Airtight construction prevents the moisture and humidity inside the building from being carried by unintended air leaks into the building envelope. The moisture and humidity is mainly created by daily activities such as heating, cooking, bathing, washing, breathing etc.
AIRTIGHT CONSTRUCTION IS REQUIRED FOR ENERGY EFFICIENCY.
Airtight construction prevents heat energy from escaping out through unintended gaps in the building envelope. The main reason why some newer buildings require so little heating is because of the high-performance building envelope that reduces heat movement in and out of the building. Insulation plays a key role preventing unwanted heat-loss and so does airtightness. The air barrier also keeps the warm air inside the building, preventing it being lost through gaps in the building envelope.
AIRTIGHT CONSTRUCTION IS REQUIRED FOR COMFORT.
Airtight construction is a drought-free building envelope. This means that the building envelope prevents cold droughts from entering the building and causing discomfort.
AIRTIGHT CONSTRUCTION IS REQUIRED FOR EFFICIENT HEAT RECOVERY VENTILATION.
As already mentioned above, ventilation air needs to enter and leave the building where it is designed to do so. With airtight construction, air movement in and out of the building is controlled and this can be achieved. Without airtight construction, the heat energy in warm indoor air leaks out through the building envelope and cannot be recovered, it is lost.

PROFESSIONAL TESTS
HOW IT WORKS
BLOWER DOOR TEST
A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings.
SMOKE PENCIL TEST
The Smoke Pencil is a professional handheld air leak detector used by energy raters, HVAC technicians, auto mechanics, and contractors to identify drafts and air leaks in a home, business, or automobile.
Table showing common airtight tests based on information from â&#x20AC;&#x153;Airtightness Testâ&#x20AC;?2
WHAT CAN YOU DO AT HOME4? Step 1: Close all windows in a room. Step 2: Hold a light weight tissue near the edge of each window/ opening Step 3: Check to see if there is any motion occurring on the tissue. Step 4: If the tissue is showing movement, contact someone who can do a test for your home.

VAPOR CONTROL FUNCTION + HOW TO IMPLEMENT IN YOUR HOME The function of a vapor barrier is to keep out the migration of water vapor. Where it is located in an assembly and its permeability is a function of climate, the characteristics of the materials that comprise the assembly and the interior conditions. Vapor barriers are not typically intended to eliminate air from coming through. This is the function of air barriers, how they work, and how you can implement them in your home.
81
WHAT IS THE PROBLEM? Incorrect use of vapor barriers is leading to an increase in moisture related problems. Vapor barriers were originally intended to prevent assemblies from getting wet. However, they often prevent assemblies from drying. Vapor barriers installed on the interior of assemblies prevent assemblies from drying inward. This can be a problem in any airconditioned enclosure. This can be a problem in any below grade space. This can be a problem when there is also a vapor barrier on the exterior. This can be a problem where brick is installed over building paper and vapor permeable sheathing.3
Vapor barriers stop diffusion of moisture through solid materials

DO YOU WANT TO BE RELAXED AND COMFORTABLE?
83
VAPOR CONTROL STRATEGIES As building science progresses and increasingly influences the way houses are built, attention to detail and accuracy are critical. An assembly that calls for a vapor barrier, Images to the right, is designed to stop moisture on one surface, under a concrete slab. For example, while more permeable vapor retarders allow some movement of moisture. If walls, roofs, or floors are built with the wrong vapor-retarding products, a structure can trap moisture. Misusing these terms leads to confusion in product choice, which ultimately can lead to failure where it matters most in your home.2

WINDOW WALL SYSTEMS SINGLE PANE TO TRIPLE PANE: WHAT YOU NEED TO KNOW Windows are a key area of a home; it can literally make or break the energy efficiency of your house. Understanding how window systems work and allow the transfer of energy in and out of your home is very important. Typically, modern homes have double or triple pane windows, which create a better barrier between the indoors and outdoors. However, most historic homes â&#x20AC;&#x201C; like 4098 Fullerton â&#x20AC;&#x201C; have single pane windows, making it a lot less energy efficient. That is why window systems are a crucial element in energy efficient homes.

VENTILATION AND LIGHTING COMPARING DIFFERENT LIGHTING STRATEGIES AND PASSIVE AIRFLOW STRATEGIES This section reviews two different passive airflow strategies to reduce your carbon footprint, while also saving money and most importantly creating a constant, healthy airflow. You can also control light and heat-loss in your home by utilizing light diffusing systems. The following pages compare a number of strategies and different variations that you can implement in your home.
99
VENTILATION CONTROL Natural Ventilation1 methods rely on external forces provided by nature to provide natural cooling methods for your house. Using natural ventilation methods has multiple benefits such as;
PROS
Both methods of ventilation have their pros and cons. However they both are passive ways of cooling your house with little to no effort and wonâ&#x20AC;&#x2122;t brake the bank
Optimal for smaller, single story homes
CROSS VENTILATION Cross Ventilation1 relies on wind energy to force cool air into your house while also pulling hot air out the other side.
100
Doesnâ&#x20AC;&#x2122;t cost anything, just opening windows Quickly cools and regulates temperatures
CONS
Building must be on an open site Perpendicular to wind direction Contain plenty of window openings
PROS
Good in all types of houses
STACK VENTILATION
Doesnâ&#x20AC;&#x2122;t cost much
Stack Ventilation1 relies on the buoyancy of air at different temperatures to cool your house. As hot air rises and is expelled from the top of the house, cooler air is sucked in towards the bottom.
CONS
This method works in every building system and is more suitable the Michigan area.
Works in all weather conditions Constantly cooling
Building requires a vent at the top of the building Very slow at cooling
101
DAYLIGHT CONTROL BLINDS Blinds are typically multiple pieces of wood, vinyl, or metal that can control the direction of light entering into a space.2
SHADES Shades are a fabric panel attached to a roller or frame and come in a variety of materials. They are usually fitted to fit each window system perfectly.2
CURTAINS Curtains are usually hung above the window system and can be swung open or closed. Often times the are see-through, only used to limit the amount of light passing through.2
102
CURTAIN SYSTEMS
LIGHT DIFFUSING SYSTEMS Light Diffusing window coverings use specific materials limit the amount of light that pass through them, making the light more softer and desirable. Best suited for living areas such as kitchens and dining rooms.2
BLACKOUT SYSTEMS Blackout window covering systems often have a slim foam backing to them preventing all light from passing through them. Best suited for areas that require darkness like bedrooms and theaters.2
INSULATION SYSTEMS Insulated window coverings use a cell like structure to help keep heat inside your house and keep the cold temperatures out. Best suited for homes in colder climates or for windows with low insulation value.2
103
LIGHT SHELVES WHAT ARE LIGHT SHELVES Light shelves, when placed strategically around windows, allow light to bounce off a smooth flat surface which in turn will bounce light off of the ceiling and across the room, lighting up more space.
OUTDOOR LIGHT SHELVES A system where the light shelf is placed outside of the space. Having the light shelves on the exterior turns them into a facade element while also leaving more room inside.
INDOOR LIGHT SHELVES A system where light shelves are placed inside the space. Having the light shelves inside optimizes the light bounces. Having the shelves inside also keeps them from being seen when outside.
WHY USE LIGHT SHELVES Light shelves prevent sun-spots, and areas that are highly concentrated with sunlight to be spread more evenly throughout the space. Reduces the use of indoor lighting needed during the day, saving on energy costs. 104

CONDITIONING SYSTEMS WHY THE WAY YOU HEAT AND COOL YOUR HOME IS SO IMPORTANT The heating system you choose for your home is very important. Ultimately, it will determine the cost of your energy bills and your comfort level for many years to come. Just because the majority of people have something, does not mean its the best option. There is much to consider when choosing your conditioning system. The initial cost, the operating costs, what type of energy is it using or not using, and many more.

A standard furnace is what you will find in the majority of homes in the Detroit area. Though, they have a relatively low instillation cost, compared to other systems; operating costs can become quite high. Furnaces are a typical choice due to availability. However, there are many, more efficient options to choose from. Retrofitting a house without ducts can be expensive and time consuming.

HIGH EFFICIENCY can be zoned to create more efficient heating and cooling.
A mini-split system is similar to a forced air furnace. It uses a series of smaller units to condition the air. Either, producing heated or cooled air. The system is also more efficient than a furnace. It does not have to transfer its conditioned air through large duct systems, which can result in a loss of efficiency. The smaller units also allow you to keep rooms at different temperatures. The system uses very little space. It can be mounted on the wall, in a variety of rooms; or be disguised in the ceiling or attic. The Cons of the system is the unit hanging on the wall. Although, through more sophisticated instillation methods, this can be avoided.

A geothermal heat pump system circulates liquid into the ground, the liquid then extracts the naturally occurring heat form the ground. The heat from the ground is then transferred into liquid running through tubes in your floor. Liquid is much more efficient at carrying heat energy, making it more efficient to run. The system takes up little space. However extensive ground works has to be done in order to bury the tubes under your yard. On the inside of the house the system can be virtually invisible, as it can be installed under the floors. The downsides of these systems is that they have a very large initial cost. Also, if your home does not already use a liquid based system such as: baseboard heat. The cost and process to install would be difficult.

ELECTRICAL SYSTEMS AND APPLIANCES DETERMINING PAYBACK PERIOD AND LONG TERM FEASIBILITY Buying new appliances is an intimidating experience that many homeowners dread. Analyzing the long term impacts of certain appliances allows the homeowner to make informed decisions. In many cases, it is cheaper to replace an old, inefficient, appliance with a newer, more efficient model.
121
APPLIANCE LIFE CYCLE ASSESSMENT WATER HEATER ENERGY COMPARISON Water Heaters are one of the most energy-intensive appliances in the home4. Efficiencies vary between models depending on the fuel source and operating strategies1. Electric Water Heaters are less efficient at heating water than their gas counterparts. However, electricity is less expensive than natural gas2. Natural Gas Water Heaters are usually more expensive than electric water heaters. However, because natural gas is more efficient at heating water, these units usually have lower operating costs. This leads to long term benefits2. Heat pump water heaters use electricity to move heat from one place to another instead of generating heat directly. To move the heat, heat pumps work like a refrigerator in reverse5.

APPLIANCE LIFE CYCLE ASSESSMENT CLOTHES WASHING AND DRYING MACHINES Washers and Dryers have developed to use less energy. These two appliances usually work in pairs. An efficient EnergySTAR washing machine wrings more water out of the clothes than a traditional washer. This makes the dryer more efficient because there is less water to remove from the clothes1. Newer Washing machines use, less electricity, less water, and remove more water at the end of their cycle than older models1.

ELECTRIC LIGHTING LIGHTING DECISIONS HOME OWNERS CAN MAKE FOR A MORE ENERGY EFFICIENT HOME Why switching your light bulbs to LED bulbs makes such a big difference in the efficiency of your home and the annual cost of electricity. Information about home lighting is broken down by Household Income (HHI) to highlight inequality in energy efficient choices.
129
BULB TYPE: CFL Compact Fluorescent Lamp (CFL) lighting products have become more efficient over time, most using costing less than $2/ annually per bulb. However, CFL light bulbs last only about 6,000- 15,000 hours1.
BULB TYPE: INCANDESCENT The traditional incandescent light bulb has an average lifespan of about 1,000 hours, making it the shortest life of all common residential light bulbs1.
130
BULB TYPE: LED Light Emitting Diode (LED) lighting products produce light approximately 90% more efficiently than incandescent light bulbs. LED bulbs can last up to 50,000 hours, about 3 times longer than the longest CFL bulb lifespan or up to 50 times the lifespan of an incandescent bulb. offered in 4 shapes, 5 colors (warm to cool/daylight), 3 wattage amounts Energy Star certified LED bulbs use up to 90% less energy than standard bulbs and can last 15 times longer2.

Timers and dimmers are a simple and affordable way to save energy. Timers are a simple way to save energy in case people forget to turn off lights and can be on a set schedule you choose. In most cases, lowering your lights to 75 percent capacity can save 20 percent of the energy needed to power the bulb. Dimmers give the power of choice to the people using them. Lighting level changes based on natural lighting, task, etc, so itâ&#x20AC;&#x2122;s both unnecessary and wasteful to use a two-choice on/off switch.

MATERIALITY SELECTING MATERIALS FOR THE BENEFIT OF HOMEOWNERS AND THE ENVIRONMENT Materiality is an important part of any house or building a user occupies. Building materials have an impact on a health, comfort, money, and the surrounding natural environment. Because of this, the idea is to understand the types of materials that should be used as well as the types of materials that should be avoided or utilized the least.
137
When it comes to selecting materials for your home, the following must be taken into consideration: ics m ra Ce

ZERO LEVELS OF VOCS3 Construction and household materials should be free of volatile organic compounds (VOCs), which are groups of chemicals that can cause serious health issues among humans and` the natural environment. VOCs include benzene, ethylene glycol, and formaldehyde and are often found in paint, carpet, cleaning products, and insulation.
VOCs are linked to the onset of asthma and cancer
VOCs negatively impact the Earthâ&#x20AC;&#x2122;s atmosphere
VOCs deteriorate the health of vegetation
VOCs damage the nervous system
LOCALLY SOURCED4 Locally sourced materials help cut down on transportation costs and as well as help cut down on distances, therefore lowering the amount of harmful gases emitted from trucks into the atmosphere. 139
ENVIRONMENTALLY CERTIFIED Materials should meet eco-friendly certifications in order to be considered safe for homes and the environment. The following are examples of “green” certifications:
“GREEN GUARD” CERTIFIED5 The Green Guard certification ensures that products (such as paints and finishes) meets strict chemical emissions limits to improve the indoor air quality.
Based on information from the UL GREEN GUARD Certification Program15
“FSC” CERTIFIED6 The Forest Stewardship Council certification ensures that wood products for floors and walls come from responsibly managed forests
“LBC DECLARE” CERTIFIED

SOLAR POWER PV VS PVT3 The photovoltaic cell is the basic element. Photovoltaics (PV) convert solar energy into electricity. High temperatures of the PVs causes a high electrical resistance that limits efficiency of the photovoltaic systems.
PVT3 The PV panels convert solar radiation into an electric current that can be used on-site, stored for later use, or fed back to the electrical grid for financial incentives. The majority of the solar radiation striking the PV panels, however, is lost as heat energy.
PV3 A PVT system draws the excess heat away from the PV modules, significantly increasing their electrical output. The heat generated from the PV and solar thermal collector panels is used to heat the buildingâ&#x20AC;&#x2122;s fresh air supply.
148
On-Grid Systems are solar PV systems that only generate power when the utility power grid is available. They must connect to the grid to function. They can send excess power generated back to the grid when you are overproducing so you credit it for later use. Benefits: These are are simplest systems and the most cost effective to install. These systems will pay for themselves by offsetting utility bills in 3-8 yrs. Downside: These do not provide power during a grid outage.
These systems allow you to store your solar power in batteries for use when the power grid goes down or if you are not on the grid. Hybrid systems will even send excess power to the grid for credit for later use. Benefits: Provides power for your critical loads when the power grid is down. Downside: Cannot be expected to provide power for all your loads. Off-Grid systems require a lot more specialized equipment to function that is more costly and more complex to install.

SOLAR POWER: BUYING VS. LEASING WHAT IS A SOLAR LEASE? A solar lease is a financing option for residential solar panels where the homeowner leases panels from a solar company. In a lease, you pay to rent the solar power system, typically for less than you were paying for electricity, The contract usually lasts for 15-20 years. There is often no down payment and maintenance is the responsibility of the solar company. The homeowner does pay a fee to the utility company to stay connected to the grid, At the end of the contract, the lessee can renew, buy the panels outright (often for a discounted price), or have the panels removed9.

WIND POWER Instead of using electricity to make wind, wind turbines use wind to make electricity. Wind turns the propellerlike blades of a turbine around a rotor, which spins a generator, which creates electricity11.
SIZES: UTILITY-SCALE WIND TURBINES
Larger wind turbines are more cost effective and are grouped together into wind plants, which provide bulk power to the electrical grid.11
OFFSHORE WIND TURBINES
Offshore wind turbines tend to be massive, and taller than the Statue of Liberty. They do not have the same transportation challenges of land-based wind installations. These turbines are able to capture powerful ocean winds and generate vast amounts of energy.11
SINGLE SMALL TURBINES
Typically used for residential. Small turbines can be used in hybrid energy systems with other distributed energy resources. These systems are called hybrid wind systems and are typically used in remote, off-grid locations and are becoming more common in gridconnected applications.11
152
Advantages4 • Cost effective • Wind Farms create jobs • Enables Industry Growth • Clean Fuel Source • Abundant and Inexhaustible • Sustainable • Wind Turbines can be built almost anywhere • Tax credits available • State rebates
Disadvantages4 • Expensive • Good wind sites are often located in remote locations, far from cities where the electricity is needed • Turbines might cause noise and aesthetic pollution • Turbine blades could damage local wildlife • Requires a minimum wind speed

The entrance to 4098 Fullerton is located on the homeâ&#x20AC;&#x2122;s side street. To draw attention to the entry, the original architect: Nathan Johnson, placed floating frames over the doorway.
In this renovation proposal landscape was used to further accentuate the entry sequence. A mall of trees was added on the west side of the property (left of photo). The mall of trees add much needed shade to the west, while providing a framing mechanism to the front of the house. A series of red hedges were brought in to further highlight the path one should take to enter the home. Due to the extensive damage of the exterior sheathing. A restoration must be completed. To respect the vertical window bands of Nathan Johnsonâ&#x20AC;&#x2122;s design. A fluted sheathing was used between the bands to further accentuate their prominence. 168

HVAC SYSTEM With Passive House Design a specific Requirement has been dedicated Specifically to air exchange. Fresh air must be constantly supplied to all spaces in the house creating a more healthier, breathable space. Heat Recovery Unit (HRU) A heat recovery unit pumps in fresh air from outside that is then heated/ cooled with the existing air from in the house where it is then dispersed throughout the house. This system can be used during the winter for heating and in the summer for cooling.

HOT WATER SYSTEM In order to reduce the energy costs for the Passive House design solar panels have been placed along the roof of the house to collect solar power which is then sourced to the city and reduces cost on the hydro bill. By running the water intake line through the solar panels it both heats the water reducing costs, and cools the solar panels which improves performance. The water is then stored in a boiler until needed throughout the house.

LIVING BUILDING CHALLENGE DESIGN SCHEME The Living Building Challenge Certification aims to provide the framework of how to achieve a highly sustainable and eco-friendly structure. This certification is composed of several performance areas or “petals” that the building must abide by. These “petals” will be implemented into the Nathan Johnson home with the intent of making it more sustainable and eco-friendly.

LEED RENOVATION DESIGN SCHEME PROPOSAL FOR 4098 FULLERTON Leadership in Energy and Environmental Design, commonly known as LEED, aims at transforming the way buildings and communities are designed, built and operated â&#x20AC;&#x201C; enabling an environmentally, socially responsible and healthy environment that improves the quality of life. Looking at the Fullerton project through the perspective of LEED will create a sustainable home that uses less energy and water, improves indoor air quality, and saves maintenance costs.
203
BREAK-DOWN OF LEED RATING SYSTEMS LEED is a points based rating system that is used internationally. It is recognized for healthy, highly efficient, and cost-saving buildings. There are different criteria (rating systems) based on the type of project. This includes new construction, interior fit outs, operations and maintenance, and core and shell. Visit the LEED website at usgbc.org/leed for more information about the different rating systems. In the Fullerton project, the BD+C for Homes rating system will be implemented for this design scheme.

LEED ZERO On top of obtaining a LEED certification, extremely well preforming projects have the opportunity to obtain a â&#x20AC;&#x153;LEED Zeroâ&#x20AC;? designation if net zero goals are achieved and monitored for a 12 month period. There are four categories for this classification: carbon, energy, water, and waste. The Fullerton project will focus on obtaining the LEED Zero Energy and Water certification. 204
HOW THE POINT SYSTEM WORKS PL A TIN
There are 4 designations that a project could obtain: LEED Certified, LEED Silver, LEED Gold, and LEED Platinum. This depends on how many points the project satisfies based on the primary goal to reduce carbon.

The drawing below shows the relationship of the interior space to the exterior as well as the materiality throughout the house and site.
LANDSCAPE PLAN
With a formal and linear massing and faรงade, the landscape becomes an opportunity to embrace the organic freedom of nature.
MICHIGAN WILDFLOWER ASSORTMENT o Low maintenance o Requires less water
VEGETABLE GARDEN BEDS o Raised to provide accessibility for all ages
PATIO AREA RAISED PORCH o Connect with neighbours o Interstitial space between public and private
o Private area for home owners to enjoy the outdoors
PERMEABLE PAVERS o Allows water to be absorbed into the ground o Accessible path around the home
MARY POTTER CRABAPPLE TREE o Reduces glare and direct light in the living room o White blooms provide contrast against very red faรงade
PENNSYLVANIA FESCUE GRASS o Low maintenance o Holds up well to foot traffic

INTERIOR + EXTERIOR SPACES TRANSITIONING FROM PUBLIC TO PRIVATE Nathan Johnson used large wrap-around panels of glass to dissolve the harsh edges relating the building to the exterior. We’ve used these these points to connect interior spaces to similar e adjacent exterior spaces.
AGE IN PLACE The flex room offers a variety of programs in the Northeast corner of the house. To the right, it’s shown being used as a playroom, an office, and as an inlaw’s suite to allow the house owners to age in place.

Keeping with the original vision of Nathan Johnson, the structure exposed in the ceiling as well as the double height space were both maintained.

Replacing the wall seen on the back of the kitchen allows for both a private space located towards the back of the house and space for additional appliances and storage in the kitchen.

HISTORIC PRESERVATION
In order to maintain Nathan Johnsonâ&#x20AC;&#x2122;s original vision for the home, it was decided that the exterior materials be replaced and updated according to historic preservation guidelines. The wood paneling that was initially used was covered over the years with vinyl siding. This scheme brings back the traditional wood siding which is painted complementary to the red brick that Johnson had originally included in the house. The metal trimming was also cleaned and restored to its original color. With new triple pane windows and insulation added to the interior, Nathan Johnsonâ&#x20AC;&#x2122;s historic vision from the outside was able to be retained and will continue to live on for the years to come.
