base case *

 

Electricity costs are based on late draft of the forthcoming SAP 2001, that is, 7.92 £/GJ off peak and 20.91 £/GJ on peak.

Assuming 10% on peak and 90% off peak consumption gives a weighted average of 9.22 £/GJ

Gas costs (also based on SAP 2001 figures) are 4.14 £/GJ

Gas conversion factor 0.19kg CO² / kWh

Electric conversion factor 0.44kg CO² / kWh

U-Value of Existing Wall

 

LAYER	THICKNESS	CONDUCTIVITY	RESISTANCE
Internal surface	n/a	n/a	standard	= 0.123
Plaster	0.015	0.500	0.015 / 0.500	= 0.03
Internal brick	0.105	0.62	0.105 / 0.62	= 0.169
Exposed brick	0.105	0.84	0.105 / 0.84	= 0.125
External surface	n/a	n/a	standard	= 0.055
			TOTAL RESISTANCE	= 0.502
USING u =   1   =     1             Rt    0.502 =  1.99 w / mk ( u-value )

 

With the addition of . . .

	40mm new insulation plaster / render, u-value = 0.81 w/mk giving a 60% energy saving.
	50mm new insulation plaster / render, u-value = 0.70 w/mk giving a 65% energy saving.
	60mm new insulation plaster / render, u-value = 0.62 w/mk giving a 69% energy saving.

 

The plaster / render has the added benefit of sound insulation qualities which will comply with the proposed amendments of Document E of the Building Regulations with initial test results showing a 3 decibel reduction as will be required.

 

Wallreform is 89% MORE thermally efficient than any standard render.

 

WHY use anything else?

 

HELP THE ENVIRONMENT as buildings account for 50% of CO² emissions.

 

 

Comparative Materials

 

Glasswool. mat / fibre	0.040 w/mk
Fibre insulation board	0.055 w/mk
Mineral wool	0.040 w/mk
E P S	0.040 w/mk
Plaster	0.500 w/mk
Render	0.500 w/mk
Plasterboard	0.160 w/mk
Woodwool slab	0.100 w/mk
Concrete block (lightweight)	0.190 w/mk
Urea formaldehyde foam	0.040 w/mk
Wallreform confirmed by the B.B.A.	0.055 w/mk

 

Equal to 89% better than standard renders, equivalent to insulation boards and can be equal to cavity wall insulation.

 

Wallreform can be applied to 40mm thickness in a single coat. It has the benefit of overcoming the problems inherent with rigidboard insulation systems, being mechanically stronger and crack resistant.

 

Any structure can be coated and a brick finish can be recreated.

 

Product can be sprayed for larger contracts

 

 

Case Study - Project Wallreform

The following case study illustrates the energy saving on a 3 bed roomed terraced / semi house with a solid wall.

Existing Heat Loss Calculation

Below are the calculations to determine how much heat loss is currently being exhibited.

 

Fabric Heat Loss
Surface	U-Value		Area		Dt		Watts
Window	5.60	x	9.00	x	17	=	856.80
Door	3.00	x	4.00	x	17	=	204.00
Wall	2.10	x	91.50	x	17	=	3266.55
Roof	3.00	x	42.00	x	17	=	2142.00
Floor	2.00	x	42.00	x	17	=	1428.00
Total Fabric Heat Loss						=	7897.35

 

Fabric Heat Loss	=	Pf	=	U	x	A	x	Dt
		heat energy lost / time		u-value		area		difference in internal external temperatures

 

Ventilation Loss

Cv x n x v x Dt = 1300 x 1.5 x 231 x 17 = 7657650 / 3600 Total Ventilation Loss = 2127.13W

 

Ventilation Loss	=	Pv	=	Cv	x	n	x	v	x	Dt
		heat energy lost / time		volumetric capacity		air change		volume		difference in internal external temperatures

 

Heat Gains
South facing windows	=	680 mj/m²	x	4.5	=	3060
North facing windows	=	250 mj/m²	x	4.5	=	1125
3 occupants inhabit the property	=	1000 mj/m²	x	3.0	=	3000
Cooking by gas					=	6500
Water heating					=	2000
Electrical					=	3000
Total Heat Gain					=	1868.50

 

Total Heat Loss - Before Wallreform

= ( Fabric Heat Loss + Ventilation Loss ) - Heat Gains = ( 7897.35 + 2127.13 ) - 1868.50 = ( 10024.48W x (33 weeks x 7 days x 24 hours x 60 mins x 60 seconds) ) - 1868.50     ( heating assessment is carried out over 33 weeks, the seasonal standard period ) = ( 10024.48W x 19958400 ) - 1868.50 = 20007 - 1868.50 = 181.38 GJ at £4.26 GJ = £771.06

 

Heating Requirements

181 GJ heat requirement supplied by gas convector heating system with 67% overall efficiency. Fuel calorific value = 40.6 MJ / M³ as supplied by British Gas = 67 / 100 output energy require at 181 GJ = 181 * (100/67) = 270149 / 40.6 = 6653 kg required

Heating assessment is carried out over 33 weeks, the seasonal standard period

 

Heat Loss Calculations after 50mm Wallreform Applied

When 50mm of insulation is applied to the walls a u-value of 0.70 w/mk is achieved.

 

Total Heat Loss - After Wallreform

Fabric Heat Loss (wall) = U x A x Dt = 0.70 x 91.5 x 17 = 1088.85W Total Fabric Heat Loss = reduced to 5719.65W from original 7897.35W (see calculation above)   Total Heat Loss = Fabric Loss + Ventilation Loss = 5719.65 + 2127.13 = 7846.78 * (33 weeks x 7 days x 24 hours x 60 minutes x 60 seconds)     ( heating assessment is carried out over 33 weeks, the seasonal standard period ) = 7846.78 * 19958400 = 15661 GJ - Heat Gains = 15561 GJ - 1868.50 GJ = 137.925 GJ at £4.26 GJ = £583.62 Heat Loss Cost - before Wallreform = £771.06 Heat Loss Cost - after Wallreform = £582.62 Wallreform gives a 24% cut in annual heating bills and energy used.

 

Heating Requirements

137 GJ heat requirement supplied by gas convector heating system with 67% overall efficiency. Fuel calorific value = 40.6 MJ / M³ as supplied by British Gas = 67 / 100 output energy require at 181 GJ = 137 * (100/67) = 204477 / 40.6 = 5036 kg required Fuel required before Wallreform = 6653 kg Fuel required after Wallreform = 5036 kg = 24% less fuel required

Heating assessment is carried out over 33 weeks, the seasonal standard period
